Constrained Dynamic Economical Dispatch using a Compact Quadratic Programming Method inluding Losses

Abstract

In this paper we present an improved compact Quadratic Programming (CQP) methodology, to solve the constrained Dynamic Economic Dispatch (DED) problem taking into account the ramp rate limit and the transmission line losses. The techniques include, the use of very compact and efficient code of QP Matlab function iteratively for solving the Economic Dispatch (ED), using a full quadratic form of losses based B-coefficients. We adapt the QP function by an external loop to adjust the equalities constraints, until convergence of the process. Another loop is dedicated to solve the DED problem by taking into account the ramping rate constraints. The effectiveness of the developed CQP method is identified through its application to three test systems. Computational results manifest that the method has a lot of excellent performances, and it is superior to other methods in many respects.
