Solving dynamic economic load dispatch with ramp rate limit using quadratic programming

This paper presents a comparative analysis study of an efficient and reliable quadratic programming (QP) with and without ramp rate limit constraints to solve dynamic economic load dispatch (DELD) problem 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 solution, simulations have been performed using 18-unit system. Results obtained with the QP method 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.
