Economic dispatch with valve point effect and Prohibited Operating Zones (POZs) is a non-convex and discontinuous optimization problem. Harmony Search (HS) is one of the recently presented meta-heuristic algorithms for solving optimization problems, which has different variants. The performances of these variants are severely affected by selection of different parameters of the algorithm. Intel...

An efficient Particle Swarm Optimization (PSO) technique, employed to solve Economic Dispatch (ED) problems in power system is presented in this paper. With practical consideration, ED will have nonsmooth cost functions with equality and inequality constraints that makes the problem, a large-scale highly constrained nonlinear optimization problem.The proposed method expands the original PSO to ...

Dynamic economic dispatch (DED) is one of the most significant non-linear problems in power systems. The purpose is determining the optimal power outputs of available generating units in order to meet the load demand subject to satisfying various operational constraints over a certain period of time. In real power systems, the valve-point effects should be considered that makes the DED a non-sm...

This paper presents a new efficient approach to Economic Load Dispatch (ELD) problems with non-convex cost functions using PSO-ANN. The practical ELD problems have non-smooth cost functions considering valve point loading effects with equality and inequality constraints that make the problem of finding the global optimum difficult using any traditional mathematical approach. Therefore, Particle...

The rational economic load dispatch can not only save the energy, but also improve efficiency of power systems. Therefore it is important to research economic load dispatch problem. However, The problem is a complex and nonlinear optimization problem considering valve-point loading effects of generating units; it is difficult to solve the problem using traditional optimization method. Therefore...
