Impact Valuation of all Connected Generators Separately by Power Sharing Approach in the Wind Incorporated System

Debashish Bhowmik, Ashoke Kumar Sinha

Abstract


This paper presents a maiden attempt to the impact of renewable (wind) energy on the power system from an individual generator to all demands. A modified method is proposed by which the proportion of power going from a specific generator to the loads, and to rest of the transmission networks has been traced in a grid system under thermal as well as wind-thermal environment. Also, it gives the individual load distribution and generator contribution to overall system losses. The method is simple, fast and accurate to the solution obtained. To clarify the analysis, the resolution to a sample case study is provided using the proposed method. The developed technique has been experimented on a modified IEEE 6-bus test system with thermal as well as wind-thermal generations. A wind generator of 10.2235 MW with wind speed 5.1376 m/sec has been incorporated into the system to see the impact of the wind generation to the system. To validate the method, the outcomes of both the cases under the projected algorithm of the test systems are compared.
