Impact of embedded genaration on 33 KV distribution system voltage

Abstract

Recently introduced schemes of Embedded Generation on the radial distribution lines have several remarkable advantages though· they produce some of the technical problems on the network. One of the major problems encountered is the variation of steady state voltage during the switching on/off operation of the Embedded Generators. The consumers connected on the line are subjected to larger variations during such operations. This research focuses on the study of the steady state voltage variation patterns and proposes solutions to mitigate the problem. The utilities impose several standards and require meeting specifications in connecting generators on the distribution network. Focusing on the effects on the locally connected COnStHl1erSto the network, both domestic and industrial, they are subjected to most of the prevailing technical problems arisen out of connecting Generators on the lines. Mainly, the problem of steady state voltage variations experienced by the consumer and finding ways of mitigating the same is discussed in this research paper. Data collection, application of load flow theories, modelling in SynerGEE software, analysis, application of mitigate measures on the model and the conclusion of the outcome of the research work are presented. A statistical way of approach is used to obtain the percentage of consumers affected in the case studies undertaken during the study. Recommendations are made that lead to mitigation of the problem concerned.
