USE OF GAS-FIRED CO-GENERATION SOURCES IN 20 K.V DISTRIBUTION GRIDS FROM THE PERSPECTIVE OF DISTRIBUTION SERVICE COMPANY BY THE GROUP SEARCH OPTIMIZER ALGORITHM

Abstract

The use of Gas-fired co-generation sources has been widely adopted in the electrical grids in Iran and many other countries across the world over the past few years. In this paper, the problem of locating and determining the capacity of co-generation sources has been studied from the perspective of a distribution service company. The Company is the investor of the project. The main objective is to reduce the operational cost of the electrical grids during a year. Constrains of the electrical grids and the distributed generation sources have been taken into account in modeling the problem. To solve the problem group search optimizer algorithm has been used. To do the numerical analysis a 20 kv distribution service grid has been used. The results show that operating costs reduce if distributed generation sources are used in the grids. The income from heat recovery and the amount of loss reduction in the grid are significant
