Dispersed generation planning using improved Hereford Ranch algorithm

The paper presents a new approach to dispersed generation planning based on Hereford Ranch algorithm in a subtransmission system. Dispersed generations could be photovoltaic cells, wind generation, battery storage, fuel cell, etc. A method to optimally locate such generation in a meshed network for maximizing the potential benefits is outlined using the Hereford Ranch algorithm and its improvement. The benefit expressed as a performance index is minimization of losses. The proposed method was tested for several sample power systems with 6, 14 and 30 bus types. Also, to show its effectiveness, the results of suggested algorithm are compared with those of the classical genetic algorithm and conventional second order method.
