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 multi-power generation micro-grid (MGMEG) is composed of renewable energy power generation systems such as wind energy, solar energy and biomass energy, clean energy power generation systems such as fuel cells and micro gas turbines, energy storage devices, and various types of loads. MGMEG faces many new challenges in terms of integration, operation control and energy management. As an effective research tool, the MGMEG experiment platform (TB-MGMEG) has been one of the focuses of research and development in many countries. Based on the research of MGMEG control model, this paper proposes a TB-MGMEG integration scheme, including the key technologies of hardware and software integration. The TB-MGMEG features single- and three-phase hybrid multi-AC bus systems and their energy management systems. Adopting the object-oriented technology and absorbing the successful application experience of IEC 61970 standard in the conventional power system, the energy management software architecture and information integration of the MGMEG system are realized.
