Abstract

Economic Dispatch (ED) optimization problem is the most important issue which is to be taken into consideration in power systems. The problem of ED in power systems is to plan the power output for each devoted generator unit in such a way that the operating cost is minimized and simultaneously, matching load demand, power operating limits and maintaining stability. This problem becomes more complex in large scale power systems, as it is hard to find out optimal solution because it is nonlinear function and it contains number of local optimal. Various techniques are proposed by the researchers for ED. The main objective of ED techniques is to minimize the total cost of the emission while maintaining stability of the power systems. This paper presents a review on particle swam optimization (PSO) for solving economic load dispatch problem.

Abstract

The demand of electricity is increasing very rapidly, with this increase in demand the burden on power system is increasing to meet this increasing demand, but it is very challenging because, the power system which we are using is aradial bus distribution system. The main problem while using redial system as a distribution network is the voltage drop which distorts the voltage profile of whole network. The primary cause of reduction of system voltage is, a huge amount of reactive power requirement of the load, because a large part of load is inductive. Around 13% of the generated power is wasted during transmission of power, so it is very necessary to improve voltage profile and to increase the efficiency of the network to prevent this loss of power. The PSO approach has been implemented to improve the voltage profile by optimizing the location of capacitor and to find its size. This test has been performed on the IEEE 33-bus and 66-bus radial distribution system which is designed with the use of MATLAB Software. The maximum number of capacitor units appropriate for the improvement for voltage profile is also checked in this work.
