AN EFFICIENT HEURISTIC METHOD FOR PLANNING ELECTRICAL NETWORK

Sobhy M. Farrag

   In this paper, a new and simple heuristic planning approach flexible to optimum design as well as to expansion planning of electrical transmission, subtransmission and distribution networks is presented. The procedure is initialized by considering all possible lines and conforming dummy impedance matrix for the fictitious network and a corresponding load flow solution. A criterion is established to calculate the impact of a line removal on the existing bus voltages and line flow without the need to run a new load flow solution. Accordingly, removing all possible lines successively except that causing system disintegration or overloading leads to the optimal configuration based on planning horizon year data. Examples have been incorporated to illustrate the potentials of the proposed approach.
