Dynamic Economic Load Dispatch Using Quadratic Programming and GAMS

This paper presents a comparative analysis study of an efficient and reliable quadratic programming (QP) and general algebraic modeling system (GAMS) to solve dynamic economic load dispatch (DELD) problem with and without considering transmission losses in a power system. The proposed QP method takes care of different unit and system constraints to find optimal solution. To validate the effectiveness of the proposed QP and GAMS solution, simulations have been performed using four different cases, a 18-unit, 20-unit with losses, 40-unit and a very large system consisting of 110-unit. Results obtained with the QP method and GAMS have been compared with other existing relevant approaches available in literatures. Experimental results show a proficiency of the QP method over other existing techniques in terms of robustness and its optimal search behavior comparing to GAMS.
