摘要
微电网是将可再生分布式发电集成到电力系统中最有效的解决方案之一,但单微电网在解决能量互补、提高可再生能源渗透率以及大规模可再生能源带来的不确定性问题上处理能力有限。多微电网(multi-microgrid,MMG)技术的发展为解决以上问题提供了思路,MMG通过自治管理和微电网间的能量互济,在提高电网运行的稳定性、经济性和能源利用率上优势明显。首先从MMG的能量管理框架入手,重点分析了MMG系统的主要物理拓扑结构、控制策略和能量调度策略,总结了MMG系统在面临不确定性因素影响时的主要建模方法,最后对MMG系统未来的研究方向和发展趋势做了展望,希望为MMG在能源互联网背景下的发展提供借鉴。
Microgrid(MG) is considered to be one of the most effective solutions to integrate renewable distributed generation into power system. However, microgrid has limited capacity to deal with some problems, such as hybrid multi-energy complementarity, increasing renewable energy penetration, and the uncertainties caused by the large-scale incorporation of renewable energy. The development of multi-microgrid(MMG) provides ideas for solving the above problems. MMG has obvious advantages in improving the stability, economy and energy utilization of power grid operation through autonomous management and energy interaction among microgrids. Firstly, this paper focused on the analysis of the main physical topology of the MMG, the corresponding control strategies and energy dispatching strategies in the context of MMG energy management framework. Then, the main modeling methods of MMG system under the influence of uncertainties were summarized. Finally, the future research and development trend of MMG system were prospected, hoping to provide reference for the development of MMG under the background of energy internet.
