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 mierogrid 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.
