摘要
Abstract
In order to improve the ability of consuming renewable energy output,a coordination control strategy to stabilize fluctuation of renewable energy based on heat pumps and hybrid energy storage was put forward in microgrids with combined heat and power system.Based on the analysis of structure characteristics and energy flow control mode,heat pumps were used as the heat energy conversion devices.An electricity-heat conversion model was established considering their operation characteristics.Power fluctuation suppression strategy used modular structure.Control layer of power fluctuation optimization used fuzzy control to regulate the filter time constant based on the operation state of heat pumps and hybrid energy storage,realizing the suppression between low-frequency and high-frequency components.Collaborative layer of heat control corrected the heat pump output considering users' hot demand.Results show the proposed method can achieve the optimal coordination of electric and heat energy flow,ensure the power smoothing effect and enhance the microgrid control flexibility and complementary economy.关键词
