微电网经济运行研究综述

Overview of the Economic Operation of Microgrid

微电网的经济效益是微电网吸引用户并能在电力系统得以推广的关键因素,而经济运行是微电网经济效益得以实现的重要手段。本文综述了微电网的经济运行研究状况,从网损、发电设备和经济运行研究方法3个方面详细介绍了微电网与传统电网在经济运行方面的差异,概述了目前国内外关于微电网经济运行的研究现状,从是否考虑环境效益的角度对各经济模型进行分类,并总结概括了其结构组成及特点,指出了目前微电网经济运行方面的研究重点以及有待解决的问题和不足,对从事该方面研究的人员有一定参考价值。

The economic benefit is the key factor of attrac- ting users for microgrid. Economic operation is the main measure to obtain economic benefit of microgrid. In this pa- per, a review of economic operation research on microgrid is presented, and the difference between microgrid and tradi- tional power grid is introduced in detail from three aspects, which are power loss, generating equipments and research methods. Then the current research status on microgrid eco- nomic operation is described, and economic models are clas- sified according to whether environmental benefit is consid- ered. In addition, their structure and characteristics are summarized. In the end, the research directions and prob- lems needed to be solved in economic operation of microgrid are pointed out, which is reference for the researchers in re- lated field.
