Restricted by the natural condition, as the fluctuation range and speed of power sources is more rapidly than that of loads, the power source has greater impact on the disturbance of micro-grid stability than load. Therefore,traditional system for energy management does not work anymore. In order to make full extent of its advantages such as low-carbon and economic benefits, much optimization should be imposed on energy management system. The paper put forward a novel energy management system suitable for micro-grid system concerned. The main mission and characteristics of each function is elaborated in detail. The system could achieve all-round monitor, synchronous monitor, pre-alert and multiple-target energy optimization. Compared to the original energy management system, the proposed micro-grid energy management systems could further improve the micro-grid control function, control accuracy, and provide important support to the development and application of the prototype system. Key words: Micro-grid; energy management system; monitor synchronized; forecast information; prediction of alarm; preventive control; multi-objective optimization; integrated coordination control 0 引言 微电网以分布式发电（微电源）小型化和数量多为特点，各微电源的发电特性不同，发电量与环境温度、风速、日照辐射量等条件密切相关，使输出有很大的随机性和波动性。微电网中的负荷也会随着时间、天气和经济等因素而不断变化。这使得分布式发电设备的故障率也随环境条件和时间变化，微电源和负荷之间的能量交换过程也变得更为复杂。传统的能量管理系统中，只采用侧重于监测系统稳态运行情况的SCADA(Supervisory Control And Data Acquisition)进行信息采集与监控，无法实现整体动态分析、同步监测。 对于多能源微电网，其能量管理系统需要从微电网的系统安全、供电品质、经济环保等多方面进行综合调控。 目前，国内外的研究主要针对微电网系统网络结构框架、调度控制策略以及单元级发电/储能的控制，对微电网系统级的能量管理系统的研究还处于理论起步阶段[1]。文献[2]主要对微电网能量管理系统的人机界面设计进行了优化。文献[3]提出了一种基于中央控制器分层控制
