含多种分布式电源的微电网优化配置分析

Optimal Configuration Analysis of Microgrid with Multiple Distributed Generators

分布式发电形式具备十分明显的经济社会效益,对于一些偏远地区而言,经常会出现供电不足、大电网供电巨额投资等问题,而利用风力光照资源实现供电,孤岛型的微电网配置的措施就可以有效解决这一问题,实现高效供电。随着微电网技术的不断深入发展,微电网项目的不断增多,经常会出现控制较为困难等问题,并且微电网单机电源接入下的成本极高,抑制了分布式电源的大规模利用。对此,文章基于分布式电源与微电网的概念,分析微电网的结构与组成,重点阐述含多种分布式电源的微电网优化配置策略,通过理论研究进一步推动微电网并网与孤岛运行方式实现平稳过渡。

The generation of distributed generation has very obvious economic and social benefits.For some remote areas,there are often problems such as insufficient power supply,huge investment in power supply from large power grids,and the use of wind and light resources to achieve power supply.The island type micro grid configuration measures can effectively solve the problem and achieve efficient power supply.With the continuous in-depth development of micro grid technology and the increasing number of micro grid projects,problems such as difficult control degree often occur,and the high cost of single microgrid power supply access inhibits the large-scale use of distributed power.In this regard,based on the concept of distributed generation and microgrid,this paper analyzes the structure and composition of microgrid,focuses on the optimization configuration strategy of microgrid with multiple distributed generation,and further promotes the smooth transition between grid connection and island operation of microgrid through theoretical research.
