Voltage Profile Improvement & Loss Reduction using Optimal Allocation of Svc Based on Fvsi

Abstract

Power sector is one of the factors that play an eminent role in the economic progress of a country and India has got a distinguished power sector with sources of power generation from feasible renewable energy resources to non-renewable energy resources. Owing to the fact of increasing day to day demand in power sector, integration of renewable energy sources, increased usage of non linear loads etc. results in voltage fluctuations, which in turn affects most of the customer’s load and their electricity bills too. If these voltage problems are not treated properly it may lead to serious conditions like voltage instability. Hence firstly in order to meet the increase in demand either new transmission line should be opted or the existing transmission line should be analyzed whether it is capable of handling increased load or not. Secondly to resolve Voltage fluctuation issues compensating devices should be used. Hence in this paper an effort is made to address both of the aforementioned issues, a 10-bus system is checked for existing transmission line performance under normal condition then for increased load condition , followed by an effort to shed light on the voltage profile improvement and loss reduction using SVC and also enlightens about the optimal allocation of SVC based on FVSI in a compact form.
