Distribution system interruptions are responsible for approximately 90% of outages experienced by customers. This fact alone
makes distribution reliability an important restructuring issue.
Recent regulatory developments reveal that regulators are interested in the reliability, affordability, and availability of power. It is
possible, however, for utilities to make significant investments in
network expansion and refurbishment and still fail to achieve the
desired levels of reliability and availability. Utilities will succeed in
this new environment only by understanding the ways they can
optimize investments while maintaining customer satisfaction and
reliability. PTI and Stone & Webster recently completed a comprehensive distribution reliability assessment for a major southwestern utility. Through this work, the team developed a new approach
to optimizing reliability expenditures using a fact-based process:

Our approach follows an advanced statistical technique that
includes a rigorous analysis of 3 to 5 years of historical outage
information. Feeders are grouped according to climate, overhead
vs. underground, voltage level, and other key attributes. The selection process combines these key attributes with historical reliability performance to produce a statistically valid sample at the

Our team of experts employs an inspection process utilizing
detailed data collection forms tailored to the client's system. These
forms are completed during feeder walks-down to note conditions
that could cause customer outages. Information is entered into an
appropriately designed database, which produces information
about each feeder as to the types of failures that are likely to occur.

Although not rigorously quantifiable, there are both real and

include loss of revenue to business customers and the utility, cost
of potential litigation for business interruption, and the potential
loss of customer loyalty/goodwill as a result of seeking services
and products from competitors during power outages.

While the physical inspections are progressing, another part of
the team calculates historical failure rates by protective zone and
cause code, and creates the computerized feeder models used in
PTI's DRNM (Distribution Reliability Analysis) tool. This state-ofthe-art tool allows assessment of existing and target feeder
reliability performance. Parametric studies are performed for each
feeder to determine potential reliability benefit using indices such
as SAIFI and SAIDI for each mitigation strategy. For example,
separate failure rates are calculated for main and tap line feeder
sections. Failure rates are further distilled by cause code
(e.g., animals, trees, equipment, and weather). Mitigation strategies are then selected until reliability targets are achieved. Figure 3
shows the results of parametric studies for a sample feeder. For
this example, two mitigation options (animals and animals + trees)
would reduce the base case to meet the targeted reliability level.
The R-SPACETM process provides utilities a systematic methodology to critically evaluate alternative feeder reliability options. The
process is designed to determine the best strategy based on costbenefit criteria and customer satisfaction issues. Further, since the
process relies on selecting a statistically valid and manageable
sample from the entire distribution system, the results are valid
and supportable, both for the selected feeders as well as the entire
distribution system. This approach has been successfully
employed for utility clients, and accepted by regulators as well.
Using the results from the analytical and physical processes,
an optimal mitigation strategy is formulated using a unique cost
benefit evaluation, which incorporates actual cost data experienced
by the client company for various mitigation activities. Key to this
process is the ranking and prioritization of mitigation options
based on combinations of these cost elements versus their predicted impacts on reliability. For example, the following table
shows the mitigation costs for each 0.1 reduction in SAIFI.

Short circuit calculations are available for three-phase, phaseto-ground, phase-to-phase-to-ground, and phase-to-phase faults.
Either individual faults or a series of faults may be placed at any
node in the distribution system, and faults also may be applied
sequentially to all nodes in the network.
Motor starting analysis is provided to determine the impact
of starting individual or multiple machines in the system.
PSS/AOEPT easily exchanges data with PSS/U to provide the
following additional capabilities: protective device coordination,
capacitor placement optimization, tie open point optimization,
harmonics, advanced reporting and spreadsheet data editing, and
predictive distribution reliability analysis.
PSS/AOEPT does not impose any limitations on the size of
the electrical network to be analyzed; users' computer memory is
the primary constraint. The program incorporates many of the
suggestions of PSS/U users and has been designed to work with
legacy data and systems. For example, it is backward-compatible
with PSS/U Rev. B.x raw data, construction dictionary, and
machine dictionary files. Once all of the PSS/U functionality is
available within PSS/AOEPT, PSS/U will be phased out completely.
The central focus of PSS/AOEPT's interface is the system
one-line diagram, with which users can easily create, edit, and
navigate a network (Fig. 2). Navigation of large networks is aided
by a tree view, from which users can zoom the one-line diagram to
any selected node or branch.
PTI developers are busy working on the next two releases of
PSS/AOEPT. Revision 2.0, scheduled for release in mid-1999, will
incorporate additional analysis capabilities including capacitor
placement optimization, tie open point optimization, and advanced
user-directed reporting. Revision 3.0, tentatively scheduled for the
end of 1999 or early 2000, will add protective device coordination,
harmonics analysis, and a transmission line constants calculation.
We are also working on a facility to allow users to
import/export data to and from the database of their choice using
OOBC technology. With all these capabilities, PSS/AOEPT provides
improved performance over PSS/U in a modern, easy-to-use package that will be welcomed by new and experienced users alike.
PTI created PSS/AOEPT because users wanted many issues
addressed in PSS/U that were difficult to implement, given the
legacy structure of PSS/U.
Therefore, PTI created a new architecture that is better suited
for responding to user needs. The strategy in designing
PSS/AOEPT was to decouple the interface from the engineering
analysis functions in PSS/U, and to make the new program a
familiar Microsoft Windows application.
In the process, PTI created the PSSIEngines™ suite of software libraries to carry out the core engineering calculations. Each
PSS/U engineering function was made into a separate calculation
server, or engine.
PSS/Engines are an integral part of PSS/AOEPT, but they are
open and available separately to developers who want to embed

Figure 2
Due to T&D system support benefits, it has been said that one
kilowatt-hour of injected DG power at the distribution feeder level
provides the equivalent financial benefit to the utility of up to 2
kWh of central station power. Whether or not this is true depends
on system configuration details, however, in concept it makes
sense when one considers the market cost of central station
power relative to delivered energy.
Careful placement and sizing of the distributed generators are
needed to maximize these benefits and not all systems can realize
such dramatic benefits from DG. This analysis requires a location
and system-specific study of how the added generators would
impact loading conditions and demand cycles on specific feeders
and transformers. It also requires load flow analysis to assess
how generator placements would affect voltage support and loss
Where there are significant system-wide distributed-generation
additions, the analysis needs to be extended to the entire utility
T&D system. An overall system planning analysis also would be
needed to determine how much bulk generation/transmission
capacity can be released or deferred by adding distributed generators, and to determine the optimum locations for the greatest
possible effect in deferring other equipment upgrades.
The ability of distributed generators to function in a reliable
fashion will become critical as penetration levels of DG increase.
Studies that investigate the dynamics and operational response of
DG to system disturbances are crucial to evaluating the true
capacity and reliability contributions that DG can provide to the
system. DG will offer little benefit and may actually worsen system
conditions if, for example, a transient system event causes many
units to trip off-line which were needed to carry the load and
maintain system stability!
The "dispatchability" of distributed generation capacity also
greatly impacts the potential T&D support benefits that can be
achieved. For maximum system support, these facilities need to be
operated or be available to operate at times of peak system load.
Fuel-powered generators under utility control like gas turbines,
fuel cells, and diesel. engines can be dispatched as needed, but
generators operated by customers not under utility control generally cannot. Still, a statistically reliable dispatch from a group of
such customers can be achieved if appropriate financial incentives
are offered or dispatch agreements are provided.
With intermittent, non-dispatchable, renewable resources like
wind turbines and photovoltaic systems, there is no guarantee that
renewable resources will be available when needed, and therefore
T&D-deferral values for solar and wind systems are derated from
their peak capacity ratings. Determining the derating factor
depends on many complex issues including the similarity between
the system demand cycle and the resource availability. Also, the
way in which the resource is to be used and where it is to be
placed will significantly impact its derating value.
For solar photovoltaic systems, a good match often can be
achieved with a utility that has system and local feeder loads that
peak in the summer and during mid-day periods. Experience indicates that under such conditions derated solar system capacity is
typically in the range of 50% to 80% of peak rated capacity;
however, these numbers could become much lower depending on
the nature of the capacity requirement. Given the variability and
uncertainty of solar and wind resources, it is often not advisable
for them to exceed 20% of peak feeder capacity unless analysis
shows that the system will work adequately without them.
Overall T&D support benefits can be significant, but achieving
them in practice will require careful attention to details and
advanced analyses of the system behavior under steady state and
dynamic conditions.
Distributed Generation and the
Deregulated Energy MarBle!

A new energy market is emerging due to the deregulation of
the utility industry. The cost, quality, and reliability of power will
be the guiding principles by which all electricity providers participating in this new market will be judged. A high value will also be
placed on energy sources with the most benign environmental
impact. Utilities that provide the best combination of these elements will be the winners of this market.
Distributed generation (DG) can playa significant role in the
deregulated energy market by offering environmentally sound
approaches for generating power and providing a means by which
cost, power quality, and reliability issues can be effectively
addressed for specific customers. Strategically located DG facilities can lower utility operating costs by deferring the need to
expand T&D infrastructure and central station generation. In
conjunction with these benefits, power quality and reliability of
service may also be improved at sites where DG is applied.
Technologies such as photovoltaics, fuel cells, wind turbines,
internal combustion engines, and microturbines are examples of
DG technologies that may be suitable to achieve these objectives.
Various technical, enVironmental, and economic factors will determine which energy source is most appropriate for each specific
Strategically applied DG at the distribution feeder level can
provide support for the bulk transmission and generation system
as well as for the local distribution system (see Fig.1). Here, the
need to generate and transport bulk power from a central generation facility to the load is reduced, providing the following system
• reduced power losses on both the transmission and distribution system
• reduced peak loading of feeders, substations, and transmission lines
• reduced peak loading of the bulk generation system
• support for the local T&D system voltage
• potential deferment of new generation, transmission, and
distribution facilities

Many variations of this arrangement can be used.
Photovoltaics, fuel cells, microturbines, and/or energy storage can
all be employed with a UPS in a variety of configurations.
Advanced versions of this arrangement may have inverters capable of providing reactive power support and harmonic filtering
during normal system conditions which also provide benefit to the
T&D system. One example is a 125-kVA device called Power
Enhancement and Delivery System (PEDS), which has recently
been developed by PTI and is now operational at a test site near
Albany, New York (see Fig. 3).
Distributed Generation and the
Deregulated Energy Marh:et
(continued from page 5)
Another area of focus for DG is its use as a tool to improve
power quality and reliability at specific customer sites. Ideal power
quality and reliability is a perfectly sinusoidal wave with no interruptions or transient disturbances, but in practice the power which
reaches customers is impacted by a wide range of disturbances
including long-duration interruptions, momentary interruptions,
voltage sags and swells, flicker, harmonic distortion, and various
sub-cycle transients.
With distributed generation, it is possible to make dramatic
enhancements in the quality and reliability of power enabling utilities to provide customers with a value-added energy service. The
marketing benefit of that service can match or even exceed the
cost-based contributions DG makes to traditional T&D support.
Several levels of improvement are possible, depending on the
type of distributed generation equipment used and its placement
on the system. The most basic installation is a backup generator
with automatic startup, mechanical transfer switch, and utility
paralleling equipment, including synchronizing relays, overcurrent,
and anti-islanding protection (see Fig. 2). It can eliminate longduration customer interruptions while serving as a distributed
generator during normal conditions, enabling the customer to use
it as a peak-shaving device to reduce demand charges. However,
because this arrangement typically requires 5 to 10 seconds to get
the generator on-line following a disturbance, it cannot be relied
on to eliminate unexpected voltage sags or momentary interruptions.
I _____________________ J
Figure 3. PEDS - An advanced package, such as PEDS,
upgrades the reliability and quality of power at a customer site
while also providing DG support to the T&D system. Inset photo
shows operational prototype [note: some switchgear elements
omitted in drawing for clarity]
PEDS will interface with a variety of distributed generation
sources and provide protection against outages, voltage sags, and
transient conditions as well as provide utility-system-friendly functions like low harmonic distortion and power-factor correction.
Ultimately, PEDS and other similar technologies are expected to
accelerate deployment of DG by combining the functions of power
quality and T&D support into a single package. Depending on
market conditions, such equipment could be available in sizes
from a few kilowatts to nearly a megawatt and is expected to fit
well into the new energy market.
Since distributed generation is located at the customer site,
waste heat from the DG energy source may be used for industrial
processes, space heating, or water heating at the customer facility.
Not every DG source is capable of producing waste heat and not
every DG application will need or want to use it; however, in applications where it makes sense it can really add substantial payback
to the project. Microturbines, fuel cells, and internal combustion
engines are particularly well suited to cogeneration applications.
When the waste heat is used, the total efficiency of energy utilization (including electricity and heat) can be as high as 85%, more
than double the typical utility system efficiency.
Figure 2. A basic standby DG system might be employed for peak
shaving and as a means of standby power during long outages.
However, it cannot provide protection against voltage sags and
momentary interruptions in the configuration shown here.
Commercial and industrial loads such as data processing facilities, automated manufacturing, telecommunications sites, and
other critical loads cannot tolerate momentary service interruptions and consequently may require more sophisticated protection.
By combining the generation source of Figure 2 with a short-duration uninterruptible power supply (UPS), momentary interruptions
and sags can be prevented from reaching customer loads. The
generator can then pick up the load for longer duration outage
events prior to the exhaustion of the UPS battery.
In most current applications, distributed generation is not the
lowest-cost option when only traditional T&D support benefits are
considered. However, when power quality and reliability benefits
J.t. A Stone & Webster Company
are included, many applications become viable. When waste heat
utilization and applications are included, DG may become the least
cost alternative for the customer. In order to take advantage of
these benefits, a significant change will be necessary in traditional
utility planning philosophies. In the past, utilities have placed the
emphasis on a central station generation approach that focuses on
robust T&D system design and economies of scale to achieve the
desired level of reliability and cost. Design and operating philosophies are now changing, and the idea of distributed generation
deployed as a tool for meeting these objectives will require utilities
to focus on specific smaller scale applications and services tailored
to meet individual customer needs.
Distributed generation is already being deployed by some utilities to meet these objectives, and many electricity customers have
also moved forward with their own installations to take advantage
of both cogeneration and reliability benefits. However, the costs of
DG have, until recently, been too high in most cases to allow a
widespread industry movement in this direction. Most DG solutions cost between $400 and $7,000 per kilowatt installed, with
internal combustion engines and small gas turbines occupying the
low end of this range, fuel cell technologies the middle of the
range, and photovoltaics the top end of the range. For applications
above $1,000 per kilowatt which also have associated fuel costs, it
is difficult to justify them in the current market based only on traditional T&D support benefits. If T&D support benefits are combined
with providing power quality, reliability, and/or cogeneration benefits, then higher installed cost solutions may make sense when the
total benefits over the lifetime are included. Currently, the economic
case for distributed generation is strongest for traditional internal
combustion engines, small turbines, and microturbines. Fuels cells
are rapidly progressing on a cost basis and will seriously compete
with these other energy sources in the near future. Photovoltaic systems are still too expensive to justify on a purely economic basis,
but may be justified for environmental reasons. Reductions in PV
cost are continuing and will likely make them justified on economics
alone within a few years.
The emerging DG market is in its early phases and, given the
current cost and maturity of DG equipment, the most successful
applications are those where power quality, reliability, T&D support, and cogeneration benefits can be mutually achieved. Many
electricity customers have already recognized this and have moved
forward with applications with an attractive cost-benefit relationship. Furthermore, as DG costs become less, many more applications will become viable and utilities risk losing considerable market share if they are not positioned to offer DG services and products. However, utilities need not abandon this market to others
and, in fact, may be better positioned in the long run to offer DG
services to customers as is allowed within the regulatory limitations imposed by governing authorities. There are many possible
approaches for utilities to be more DG-oriented. Utilities may sell
premium power to customers by installing utility owned DG equipment at the customer facility to provide premium grade power. The
customer would pay a premium rate over their normal rate for this
added service. The utility may also sell the waste heat from such a
facility to the customer. These extra service fees would offset much
or all of the cost of the DG unit while the utility enjoys the T&D
system support benefits. Another approach is that utilities could
sell DG equipment directly to customers and offer maintenance
services as justified by the market-this approach could also provide system support benefits while meeting customer expectations
for high reliability and low cost of service. There are many other
possible marketing approaches that could emerge and ultimately
what will occur will depend on the regulatory environment as well
as pricing strategies. Thus, while the future details of the market
are uncertain, it is clear that utilities need to move rapidly to
embrace the possibility of significant DG penetration and develop
plans for capitalizing on the emergence of this market or face the
threat of losing this market share to others.
