中文摘要：

微电网系统包含多种微电源和不同类型的负荷,受自然条件的限制,微电源的波动幅度和速度常常大于负荷的变化,因此微电源对电网稳定性的扰动也常大于其负荷,从而使得传统的能量管理系统不再适用。为了充分发挥微电网低碳、经济的优势,需要优化微电网的能量调度以使微电源得到最大利用。针对微电网系统的特点,提出了一套较为完善的微电网能量管理系统,并对其各功能模块的主要任务及其完善的特色进行了详细阐述,该系统能够实现预报、实时、历史信息的全面监测、微电网系统状态的同步监控、预报警和预防控制以及微电网的能量多目标优化运行综合协调控制功能。提出的微电网能量管理系统进一步完善了微电网的控制功能,提高了微电网的控制精度和有效性,为原型系统的开发及工程应用提供重要支持。

英文摘要：

Micro-grid system contains variety of power sources and loads .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 .Com-pared 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 ap-plication of the prototype system .
