摘要
储能系统在海岛独立型微电网中具有协调负荷和平抑波动的作用,选择合适的储能技术才能充分体现其价值和作用。首先,介绍了主流储能技术类型,并针对海岛独立型微电网特点,从技术和成本角度分析了适宜海岛独立型微电网的储能类型。其次,对海岛独立型微电网中储能系统优化配置模型进行了分析,并从储能单位功率和单位能量成本的角度对储能技术经济性进行了讨论,重点比较分析了铅酸蓄电池和磷酸铁锂电池的性能。最后,对海岛独立型微电网中储能技术的商业运营模式进行了探讨,对不同储能技术对应的补贴方式给出了建议。
As the energy storage system in the island stand-alone microgrid can coordinate load and stabilize fluctuation, only suitable energy storage technology can fully reflect its value and role. First, the mainstream type of energy storage technology is dealt with. According to the characteristics of the island stand-alone microgrid, suitable energy storage types for the island stand-alone microgrid are analyzed from a technical and cost perspective. Then, the optimal allocation model of energy storage systems in the island stand-alone microgrid is analyzed. The economy of energy storage technology is discussed from the point of view of unit power cost and unit energy cost, and mainly the performance of lead-acid battery and LiFePO4 battery is treated and compared. Finally, the commercial operation mode of energy storage technology in the island stand-alone microgrid is discussed and ways of subsidizing different energy storage technologies are recommended.
