区域微网可拓式设计及实例分析

Region Microgrid Extension Design and Engineering Case Analysis

摘要: 在创建节约型社会、加快农村城镇化进程、推进建设绿色低碳行业的大环境下，围绕可再生能源和清洁能源的开发利用，我国正逐步加大微网建设部署的力度。微网是传统电网的有益补充，可以对分布式能源进行灵活有效的组合，是未来智能电网的有机组成部分。但是，由于分布式电源的特性、电网的可接纳性以及政策因素，导致分布式电源无法大范围的推广，也影响了微网的大范围应用。本文充分考虑当前电力系统的特点、微网的功能以及国家政策等因素，提出区域微网的概念，分析了区域微网应具备的五大功能，将微网按照农村微网、城市区域微网以及偏远地区微网进行规划，设计出满足区域特征的可拓式微网结构及运行控制方案。并以云南电网科技园某微网示范工程作为案例，验证设计方案的可行性。

Abstract: China creates a conservation-oriented society, accelerates the process of rural urbanization and promotes the construction of green low carbon industry. Surrounding the development and utilization of renewable energy and clean energy, China is stepping up efforts to build microgrid. Microgrid is the beneficial supplement for traditional power grid, is an organic part of the future smart grid, and it can combine a flexible and effective distributed energy network. However, due to the characteristic of distributed power supply, power grid adaptability and policy factors, dis-tributed power and microgrid can not promote widely. In this paper, according to the characteristics of the current power system, the function of the microgrid and other factors, such as national policy, the author puts forward the concept of regional microgrid. And five functions of microgrid are analysed. Microgrid is divided to the rural microgrid, city region microgrid and remote areas microgrid in the paper. The microgrid structure and operation scheme is designed, which meets the regional characteristics. Taking Yunnan Power Grid Technology Park microgrid project as a case, it verifies the feasibility of design.
