PowerWorld Corporation | Optimal Power Flow Reserves

Available starting with PowerWorld Simulator 13, the Optimal Power Flow for Reserve Markets (OPF Reserves) extends Simulator OPF to model simultaneous energy and reserve markets. Simulator OPF Reserves helps you find the optimal economic operation of the system taking into account both energy and reserves bids. In the reserves market, generators and loads bid for the ability to increase their active power output (or reduce load active) in the short term. Generators and load resources can provide, and have separate controls to model regulation, spinning, and supplemental reserves. For each resource, the regulation reserve controls can act as a single bidirectional control or as separate up and down regulation reserves.

System areas and zones can specify reserve requirements using reserve demand curves. Requirements may be specified as combinations of regulation, operation and contingency reserves. The outcome of the combined optimization provided by Simulator OPF Reserves include security as modeled by the ISO reserve requirements, and results in Locational Marginal Prices (LMP) that reflect reserves. OPR Reserves is fully integrated with the Simulator OPF and SCOPF Add-Ons. Note that the Simulator OPF add-on is required to run Simulator OPF Reserves.

Several small sample cases are tailored especially for evaluation of Simulator OPF Reserves. These cases may be used with the free 12-bus demo version of PowerWorld Simulator.
