An optimization technique for real and reactive power allocation

Abstract

An economic schedule for real power generation is obtained by a Lagrangian method and the allocation of reactive power generation is determined by a gradient method. Alternate real and reactive power requirements for economic system operation are computed until the total cost is minimized within the limitations imposed by system constraints. Repeated solutions of the network equations are used to incorporate the effects of transmission losses in lieu of a precalculated transmission loss formula. The computer program provides a means to determine the optimum use of available real and reactive power generation and to plan economically for future requirements.
