PowerWorld Simulator - Optimal Power Flow Analysis Tool (OPF)
The PowerWorld Optimal Power
Flow Analysis Tool (OPF) is an optional add-on to the base Simulator package.
Simulator OPF starts with all the functionality of the
original Simulator, but then adds an optimal power flow (OPF). Simulator
OPF provides the ability to optimally dispatch the generation in an area or
group of areas while simultaneously enforcing the transmission line
and interface limits. Simulator OPF can then calculate the marginal
price to supply electricity to a bus (locational marginal price or LMP),
while taking into account transmission system congestion.

The advantages of the Simulator OPF over other commercially available
Optimal Power Flow packages include the ability to:
-
display the OPF
results on system one-line diagrams and contour the results for ease
of interpretation
-
export the OPF results to a spreadsheet, a text file,
or a PowerWorld AUX file
for added functionality
Simulator OPF grew out of a project completed with the
U.S. Energy Information Administration (EIA) looking at the cost of
supplying electricity in the Northeast portion of the U.S. Because
this project involved studying relatively large systems, greater than
9,000 buses, we had to make Simulator OPF fast. As an example,
the figures below show contours of several thousand bus marginal costs
in the New York and New England regions using FERC 715 data for the
power system values and EIA supplied generation costs. Solving the OPF
for this 9,270 bus system - including enforcing approximately 20 binding
transmission line MVA constraints and calculating the bus marginal
prices at 5,627 buses - took about 10 seconds using a 500 MHz Pentium
III machine.
