| 针对交直流微电网中多种能源间的协同控制能力和利用效率较差这一问题，本文考虑将冰蓄冷系统集成到交直流混合微电网中，并提出了一种基于双向接口变流器的多能互补交直流混合微电网多模式自主协同控制策略。分析了系统运行在以下几种情况时所提策略的准确性：（1）在储能期内，冰蓄冷系统和储能系统可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，其余冷负荷和电力负荷由储能系统根据其额定容量比共享。（3）在发生故障时，系统能迅速回到稳定状态。在PSCAD/EMTDC中进行仿真分析，验证了所提策略的有效性。 |

| To address the issue of suboptimal coordination capability and utilization efficiency among various energy sources within alternating current/direct current (AC/DC) microgrids, this paper explores the integration of ice storage systems into hybrid AC/DC microgrids. It proposes a multi-mode autonomous coordination control strategy for a hybrid AC/DC microgrid with multi-energy complementarity, based on bidirectional interface converters. The accuracy of the proposed strategy is analyzed under the following scenarios: (1) During the energy storage period, both the ice storage system and the energy storage system can absorb energy according to their rated capacities. (2) During the energy release period, the ice storage system is activated first, with the remaining cooling and electrical loads shared by the energy storage system according to their capacity ratios. (3) In the event of a fault, the system can quickly return to a stable state. The effectiveness of the proposed strategy is verified through simulation analysis in PSCAD/EMTDC. |
