Research on Distributed Electric Grid Economic Dispatch Model Based on Multi-objective Optimization

Abstract

At present, the electric grid economic dispatch problems present a trend of non-linearity, high dimensionality, discretization and multi-objective. The principle and objective of electric grid dispatch operation are facing new challenges. This paper establishes a distributed electric grid economic dispatch mathematical model based on multi-objective optimization, considers three objective functions, such as maximization of economic benefit, minimization of unit operating energy consumption and minimization of polluting gas emissions from the perspective of electric grid partitioning and coordination calculation, and elaborates the solving process of the model. The results of calculation cases show that this method can achieve a good result in the optimization process of distributed electric grid economic dispatch.
