基于清洁能源发电系统的微网技术

清洁能源发电系统联网对于缓解传统电网供电压力，改变能源结构具有重要作用。通过分析以清洁能源发电为主的分布式电源大量联网的局限性，引入了微网技术，介绍了微网的相关概念及其基本结构、三种微网的基本控制模式：恒功率控制、考虑分布式电源功率限制的功率控制和联合最优功率控制．最后提出了微网研究中需要重点解决的问题。

Microgrid Technology Based on Clean Energy Power Generation System

grid connection of the clean energy power generation system plays an important role to relieve the pressure of the traditional electrical network, and it can change the energy structure. This paper introduces the microgrid technology by analyzing the limitations of the large scale grid connected distributed generations which are mainly by clean energy, represents the definition and the basic structure of microgrid, and introduces the three kinds of control strategies which include constant power control, power control with considering limitations of distributed generations, and comprehensive optimal power control. In the end, this paper puts forward some problems which needs to be worked out in microgrid in the future.
