Joint Scheduling Strategy for Multi-Virtual Power Plant Based on Temperature-Controlled Load's Participation
Temperature-controlled loads,such as air conditioners,play a crucial role in the optimal scheduling of virtual power plants(VPP).In order to deal with the instability of renewal energy,a joint scheduling strategy of multi-virtual power plant based on the participation of temperature-controlled loads was proposed.Firstly,the temperature-controlled loads'aggregation model is studied,and the multi-virtual power plant's joint dispatching framework of distributed energy resources is constructed.The joint dispatching plan is formulated according to the forecast data in the pre-day stage,the multi-virtual power plant management center carries out multi-energy complementarity for each VPP,and the temperature-controlled loads model considering the user's willingness is introduced in the pre-day stage.In the intraday stage,the scheduling plan is revised on a rolling basis according to the short-term forecast data to reduce the supply and demand deviation caused by the instability of renewal energy,and finally the Cplex simulation invoked by Matlab verifies that the proposed strategy not only ensures the reliability of power supply,but also effectively reduces the compensation cost caused by the prediction deviation.
