基于D-OSGi的光伏微电网能量管理系统

Photovoltaic Microgrid Energy Management System Based on D-OSGi

微电网需要能量管理系统(EMS)对分布式电源进行实时优化控制,但传统软件开发模型及中间件技术在模块热插拔及代码侵入性等方面尚有不足。为此,依托安徽工程大学100k W光伏微网项目,提出一种基于分布式开放服务网关(D-OSGi)的微网能量管理系统。阐述D-OSGi的扩展方法、EMS软件逻辑层划分、能量优化调度策略及SCADA图元变更机制,给出系统在宣城微网的实施方法。对典型业务模块的功能进行验证,结果表明,该系统能有效降低用户对功能进行细粒度定制和扩展的难度,方便电力系统相关科研人员对微网控制算法进行快速仿真。

Microgrid needs the Energy Management System（EMS）to optimize and control Distributed Generation（DG）,but the traditional software development models and middleware technologies are insufficient in module hot-plug capability and code invasion. Based on the 100 k W photovoltaic microgrid project in Anhui Polytechnic University,this paper proposes a microgrid EMS based on Distributed Open Service Gateway initiative（D-OSGi）,and then discusses the aspect-oriented approach to extend the D-OSGi,software logical layers of EMS,energy scheduling strategies and changes of SCADA graphics primitive. The implementation approach of EMS in Xuancheng microgrid is presented,and some tests are done for typical modules＇ functionality. The results show that the system reduces the difficulties to customize and extend functions effectively,and it is convenient for power system related researchers to simulate microgrid control algorithms rapidly.
