【摘要】：为减少储能总容量和蓄电池动作次数,提出一种计及需求侧管理的微电网能量优化策略。考虑热泵的负荷特性,根据产热量与热泵工质流速的关系建立相应的热泵系统模型。根据热负荷日需求曲线,对热泵的储热容量模型进行分析与计算;按照频率区间将微电网功率波动划分为高频成分与中低频成分,并采用模糊控制理论将波动功率在热泵、蓄电池与超级电容间进行分配。该策略对微电网进行削峰填谷,对功率波动进行抑制,实现了微电网的可靠、经济运行。算例验证了所提能量管理策略的正确性与有效性。
[Abstract]:In order to reduce the total energy storage capacity and the number of battery operations, an energy optimization strategy for microgrid considering demand-side management is proposed. Considering the load characteristics of heat pump, the heat pump system model is established according to the relationship between heat production and working fluid velocity. According to the daily demand curve of heat load, the heat storage capacity model of heat pump is analyzed and calculated. According to the frequency range, the power fluctuation of microgrid is divided into high frequency component and middle and low frequency component, and the fluctuating power is distributed between heat pump, battery and super capacitor by fuzzy control theory. This strategy can cut the peak and fill the valley, restrain the power fluctuation, and realize the reliable and economical operation of the microgrid. An example is given to verify the correctness and effectiveness of the proposed energy management strategy.
