摘要
设计一种基于电力集能器的微电网能力管理系统,由能源局域网、能源子网能量管理系统组成,采用专家控制策略多种策略,正常运行、故障处理和孤岛运行模式。电力集能器自带电网交流、微网直流、负荷交流转换等功能满足系统负荷的不同供电需求,通过微网及光伏起到能量协调平衡功能。主要能源从交流电网获取,光伏与直流微电网做为辅助能源,该系统主要负责系统级控制与协调,在子网系统实现电能管理及电能平衡。通过对微网能量管理、储能技术的高效利用、储能数据的集中管理分析,在削峰填谷、节省电费开支、延缓输配电扩容升级等方面具有良好的经济效益。
A micropower grid capacity management system based on power collector is designed,composed of energy LAN and energy subnet energy management system,with a variety of expert control strategies,normal operation,fault processing and island operation mode.The power collector has its own power grid AC,micro-network DC,load AC conversion and other functions to meet the different power supply needs of the system load,and plays the energy coordination and balance function through the micro-network and photovoltaic.The main energy is obtained from AC power grid,and photovoltaic and DC micro power grid are auxiliary energy.The system is mainly responsible for system-level control and coordination to realize power management and balance in the subnet system.Through the energy management of micro-network,the efficient utilization of energy storage technology,and the centralized management and analysis of energy storage data,it has good economic benefits in cutting peak and filling,saving electricity bills,and delaying the expansion of power transmission,distribution and upgrading.
