摘要
研究微网优化运行模式,将全景理论(Landscape theory)应用在多微网系统中,将微网聚合到一起运行以实现更好的效益。考虑微网不同分布式电源互补性,定义了全景理论对应参数,利用全景理论的能量函数将多微网进行分组聚合。在确定多微网聚合形式的基础上,建立了考虑主网连接点(Point of common coupling,PCC)波动的微网能量优化模型,对聚合前后的多微网能量优化结果进行对比分析。仿真算例表明,聚合后各微网在实现自身经济性的同时提高了系统安全性,证明了全景理论在多微网聚合方面应用的合理性和有效性。
The operation modes of microgrid are researched and landscape theory is adopted in multi-microgrid systems to group microgrids in order to achieve better benefit. Complementarity of distributed energy resources is studied to define corresponding parameters in landscape theory, then landscape energy function is taken to group multi-microgrid. Based on the aggregation alignment of multi-microgrid, an optimization model considering interactive power fluctuation of PCC is proposed and the original values and the aggregation multi-microgrid energy optimal values are comparatively analyzed. The simulation result validates that the aggregation of microgrids increases individual economic benefit and enhances security of power system. So the validity and rationality of the application of landscape theory in multi-microgrid aggregation is proved.
