[Abstract]:In order to effectively smooth the tie-line power fluctuation of electric-thermal microgrid, a cooperative control strategy based on electrothermal pump and battery is proposed. Considering the operation characteristics and energy interaction mode of electric-heat combined microgrid, the electro-thermal energy conversion model is established based on the operation characteristics of electrothermal pump. By analyzing the priority sequence of the electrothermal pump group, the number of the electrothermal pump group can be operated and the pointer of the state switching serial number is calculated. The switching sequence of electric heat pump group is calculated by cluster control algorithm considering the control limit of unit starting and stopping. Based on the state of storage charge and actual output of electric pump, the power distribution function of battery and electric heat pump is established, and the fluctuating power of tie-line is distributed between battery and electric heat pump group. The simulation results show that the proposed strategy can achieve smooth tie-line power through electric-thermal energy coordination control, and improve the complementary economy and energy utilization efficiency of the electric-thermal combined microgrid at the same time.
