多能源发电微网实验平台及其能量管理信息集成

Testbed and Information Integration of EMS for a Microgrid with Multi-energy Generation Systems

典型的多能源发电微网(MGMEG)由风能、太阳能、生物质能等可再生能源发电系统,燃料电池、微型燃气轮机等清洁能源发电系统,储能装置以及各类负载组成。MGMEG的集成、运行控制及能量管理等方面面临诸多新的挑战,而作为一种有效的研究手段,MGMEG实验平台(TB-MGMEG)一直是许多国家研究和开发的重点之一。文中在研究MGMEG控制模型的基础上,提出一种TB-MGMEG集成方案,包括硬件及软件集成关键技术。该TB-MGMEG的特点是单、三相混合的多交流母线系统及其能量管理系统。采用面向对象技术,吸纳IEC 61970标准在常规电力系统中的成功应用经验,实现了MGMEG系统能量管理软件构架及信息集成。

A typical microgrid with multi-energy generation systems （MGMEG） is composed of renewable energy generation systems including wind turbines, photovoltaic arrays, biomass etc. , clean energy generation systems such as micro gas turbines and fuel cells, energy storage units, and local loads. Because of MGMEG＇ s inherent characteristics, the integration and operation control of the microgrid face great challenges. As a cost-effective research method, testbeds for MGMEG （TB- MGMEG） in labs have been developed in some key projects all over world. This paper presents a framework of comprehensive TB-MGMEG including key technologies of hardware and software design. The feature of the TB-MGMEG is a single-phase and three-phase hybrid multi-AC-bus system with an energy management system （EMS）. An IEC 61970-based information integration and EMS software framework for the MGMEG is developed by referring to the successful experience of application of IEC 61970 to conventional power systems and adopting object-oriented programming techniques.
