【摘要】 为满足对微电网进行监控和能量管理的需要,借鉴智能变电站分层体系结构,提出了由设备层、管理层和优化层3个逻辑层次构成的微电网监控与能量管理一体化系统。并基于此,设计了位于管理层的微电网监控与能量管理装置(MMEMD)。MMEMD的主要功能包括:采用异构通信技术对微电网中各类分布式电源、储能、负荷及开关等设备进行实时监控;通过微气象监测功能对风光出力进行超短期预测;将"源—储—荷"的运行信息统一转换为IEC 61850信息模型,并通过通用面向对象变电站事件(GOOSE)通信服务与优化层进行信息交互,以及配合优化层进行微电网的多时间尺度协调控制和能量优化。在介绍MMEMD软硬件设计的基础上,构建了实验平台对MMEMD的主要功能进行了实验验证。更多还原

【Abstract】 In order to meet the needs of real-time monitoring and energy management in a microgrid,a microgrid monitoring and energy management integrated system composed of three logical levels(the device layer,the management layer and the optimization layer)is presented according to the hierarchical architecture of smart substations.Based on the integrated system, a microgrid monitoring and energy management device(MMEMD)in the management layer is designed.The key functions of MMEMD include:real-time monitoring of distributed generators,energy-storage systems,loads,switches and other devices within the microgrid through heterogeneous communication technology;ultra-short-term forecasting of wind and solar output power through the micrometeorological monitoring function;converting of microgrid operation information into an IEC 61850 information model for exchange of data with the optimization layer through the generic object-oriented substation event(GOOSE)communication service;cooperating with the optimization layer to realize coordinated control and energy optimization based on multi-time scale.On the basis of the proposed hardware and software design of MMEMD,an experimental platform is developed to verify the main functions of MMEMD.更多还原
