Implementation of ABC Algorithm To Solve Simultaneous Substation Expansion And Transmission Expansion Planning

Abstract

In this paper, the transmission and substation expansion planning is solved simultaneously by Artificial Bee Colony (ABC) optimization technique. The objective of this proposed approach is to minimize the summation of the Transmission Line Investment cost (TIC) and the Operation Cost (OC). The OC is the combination of the fuel cost of generating units and the Total Wind Power Uncertainty Cost (TWC). To formulate the mathematical structure of Simultaneous Transmission and Substation Expansion Planning (STSEP) problem the widely used DC power flow model is used. The proposed problem also considers the uncertainties in the load. The proposed model is tested on the modified IEEE 24-bus reliability test system. Numerical analyses on the results are briefly presented.
