Multi-energy hybrid AC/DC microgrids (MGs), considering ice storage systems (ISSs), can promote the flexible integration and efficient utilization of distributed generators (DGs) and energy storage systems (ESSs), provide a reliable power supply for local loads, and achieve multi-energy complementarity and energy savings at the same time. An autonomous cooperative control of multi-energy MGs is proposed in this paper, which can realize the following targets: 1) In the energy storage period, ice storage systems and energy storage systems can absorb energy in accordance with their rated capacity. 2) In the energy releasing period, ice storage systems are first put into operation, and the rest of the equivalent cooling loads and electrical loads are shared by the energy storage systems according to their rated capacity ratio. Besides, the complete system small signal model is constructed, which can be used to analyze the features and characteristics of the system and guide the optimal design of the control parameters. Finally, the effectiveness of the proposed control is corroborated by several case studies conducted in PSCAD/EMTDC.

考虑多能互补的交直流混合微电网自主协同控制

多能源交直流混合微电网（MGs），考虑冰蓄冷系统（ISSs），可以促进分布式发电机（DGs）和储能系统（ESSs）的灵活集成和高效利用，为本地负载提供可靠的电力供应，同时实现多能互补和节能。本文提出了一种多能量MGs的自主协同控制，可以实现以下目标：1）在储能期间，冰蓄冷系统和储能系统可以根据其额定容量吸收能量。2）在能量释放期，冰蓄冷系统首先投入运行，其余等效冷负荷和电力负荷由储能系统按额定容量比例分担。除了，构建了完整的系统小信号模型，可用于分析系统的特点和特性，指导控制参数的优化设计。最后，在 PSCAD/EMTDC 中进行的几个案例研究证实了所提出的控制的有效性。
