Solving Electrical Dispatch Problem Using Sine Cosine Algorithm (SCA) with Sequential Quadratic Programming

Abstract

The Power system faces a number of complex problems like Electrical Dispatch. The aim of Electrical dispatch problem is the efficient utilization of resources to provide the demanded power while generating cost turns out to be minimum and no constraint is violated either equality or inequality. The Electrical dispatch (ED) optimization problem, is necessary because of limited resources, high fuel cost and ever growing demand of power. In this research a new technique named Sine Cosine Algorithm (SCA) modified with Sequential Quadratic Programming (SQP) is introduced to tackle the Electrical Dispatch (ED) problem. The basic methodology of this technique is to apply SCA to Electrical Dispatch problem and then further improvement of results is evaluated using Sequential Quadratic Programming (SQP) which is a mathematical technique. The suggested algorithm has been implemented in MATLAB to solve ED problem and validated using the 40 unit IEEE test system with transmission losses. Finally the results of suggested algorithm has been compared with the other optimization algorithms reported in literature to show the applicability and feasibility of the suggested algorithm. The simulation results evidently prove that the proposed algorithm outperforms other techniques in terms of cost and convergence characteristics.
