Security Constrained Dispatch at the New York Power Pool

This paper describes the Security Constrained Economic Dispatch (SCD) System implemented at the New York Power Poo The Economic Dispatch program uses the differential algorithm coupled with the revised simplex technique with bounding to produce an optimal generation schedule with security constraints. The constraints used in the initial program implementation consist of generator limitations and transniission line constraints selected by the power system dispatcher. Generator limitations include megawatt minimums and maximums, response rate and regulation constraints. Curreritly 228 lines and transformer banks are monitored, operating at voltage levels ranging from 765 kV to 69 kV.
