微网并网时的经济运行研究

Research on Economic Operation Optimization of Grid-connected Microgrid

微网是智能电网的重要组成部分,作为大电网的有效补充和分布式能源的有效利用形式,微网已经引起各国学者的广泛关注,微网经济运行是其中的一个重要研究方面。在建立含多种微电源的微网模型的基础上,提出了一种通过改进粒子群算法对微网系统进行经济运行优化的方法。对一个微网系统算例进行了研究,仿真计算结果表明了所提方法的正确性和有效性。

Microgrid is an important part of smart grid, as an effective supplement of the great power grid and an effective form used by the distributed energy, microgrid has attracted wide attention, and the economic operation of the microgrid plays an important role. This paper proposed an improved PSO algorithm to solve the economic optimization problem. The economic dispatch of a small microgird example was optimized by the proposed method, simulation results show the effectiveness of the proposed method.
