微网经济调度优化模型研究综述

Survey on Economic Dispatch Optimization Model for Microgrid

微网的经济调度模型直接影响着微网运行方案的可行性和合理性,是微网经济调度研究中的核心内容。对目前已有的微网经济调度优化模型做了综述性的研究,分别从静态调度和动态调度2个方面阐述了经济调度模型,并分类概括了不同模型的组成结构及特点。静态经济调度方面从基本模型入手,依次分析了包含热电联产、环保成本等因素的模型结构及特点;动态经济调度方面则在基本模型的基础上,主要研究了包含不确定性因素的动态经济调度模型的结构组成,并分析了该模型相对于静态经济调度模型的区别与优势。最后总结了目前微网经济调度模型的研究现状与不足,并为其进一步的发展与研究提出了建议。

The economic dispatch model for microgrid directly influences the feasibility and rationality of microgrid operation scheme, it is the key content in microgrid economic dispatch research. In this paper,the present economic dispatch optimization models for mircogrid are summarized from static dispatch and dynamic dispatch, and the structure and characteristics of them are classified and summarized. In aspect of static dispatch, the basic model is introduced firstly, the structure and characteristics of models which contain some factors such as cogeneration and environmental cost are analyzed. In the aspect of dynamic dispatch, the basic model is introduced at the beginning, and the structure characteristics of dynamic dispatch models contain uncertain factors are mainly studied. The difference and advantage relative to the static scheduling model are analyzed at last. Finally, the development and insufficiency of mierogrid economic dispatch models is summed up and the development trend is looked ahead.
