Article Title: Optimal Operation of Large Power System by GA Method
by Sangita Das Biswas and Anupama Debbarma

The optimal operation of a power system, involves many considerations like economy of operation, system security, emission at certain fossil-fuel plants etc. All this considerations cannot be taken into account at the same time and as a result compromise has to be made for the optimal operation of the power system. In our work we shall consider the economy of operation, called the economic load dispatch. In an Interconnected power system it is necessary to find power generation scheduling of each power plant to minimize the operating cost. This means the power generations are allowed to vary within a certain limit to meet a particular load demand with minimum fuel cost. The main objectives of economic load dispatch are to minimize generation cost, while meeting the system load and the transmission loss of the system. The aim of this work is to solve the economic load dispatch problem with Genetic Algorithm keeping the power generation of each plant within security limit and meeting the demand of the power system. A MATLAB program will be developed to solve the economic load dispatch using Genetic Algorithm
Keywords: crossover, economic load dispatch, fitness function, genetic algorithm, and optimal power flow
