Smart Grid Economic Dispatch

Procedia Technology, 2016
AbstractThis paper describes a smart grid economic dispatch (SGED) approach without considering the network equality security constraints. The economic dispatch (ED) problem is one of the fundamental problems in the power system. The objective of ED is to reduce the total power generation cost.

Application of pattern search method to power system valve-point economic load dispatch

, 2007
Direct search (DS) methods are evolutionary algorithms used to solve constrained optimization problems. DS methods do not require any information about the gradient of the objective function at hand, while searching for an optimum solution.
