摘要
为满足微网系统监控和能量管理的需求,文章首先对微网系统进行了优化协调层、SCADA与算法控制层和设备层3个逻辑层次的分层控制研究。在此基础上,设计了位于优化协调层的微网能量管理和监控软件(EMMS),并阐述了其主要功能。其次,重点阐述了采用粒子群算法实现EMMS的能量优化功能,以及EMMS协调下级设备共同实现微网的频率稳定、电压稳定和并离网的平滑切换功能。最后,构建了实验平台和算法对其主要功能进行了实验验证。
In order to meet the requirements of monitoring and energy management of micro-grid system,the hierarchical control of micro-grid system is firstly studied in this paper. Hierarchical control consists of 3 logical levels: coordination and optimization layer,SCADA and algorithm control layer,and equipment layer. On this basis,this paper discussed the main function of micro-grid monitoring and energy management software( EMMS) in the coordination and optimization layer in detail. Secondly,we illustrate that using particle swarm optimization( PSO) to realize energy management optimization function of EMMS,and EMMS coordinating subordinate equipment together to achieve stable frequency and voltage,the switching of off-grid and on-grid operation of micro-grid. Finally,this paper constructed the experimental platform and algorithm to prove its main functions.
