Low Carbon Economic Dispatching of Virtual Power Plant Considering Changing Heat Price-integrated Demand Response
In order to realize low carbon economic operation of virtual power plant,we propose an optimal dispatching model of virtual power plant considering changing heat price-integrated demand response.Firstly,we establish an inte-grated demand response structure containing various load types,and analyze the relationship between user satisfaction and the changes of transferable,substitutable and reducible loads.Based on the energy use difference degree and time-of-use electricity price,we propose a heat price adjustment strategy that affects the changes of substitutable loads in the integrated demand response,and establish a changing heat price-integrated demand response model based on energy use satisfaction.Secondly,we analyze the influence of changing heat price-integrated demand response on energy use characteristics to realize the cooperative optimization of energy coupling and price coupling in virtual power plant.Fi-nally,combined with the stepped carbon trading mechanism,we optimize the output of the energy supply equipment to realize the low-carbon economic dispatch of the virtual power plant.The simulation results show that the proposed mod-el not only plays the role of peak clipping and valley filling better,but also improves the satisfaction of energy consump-tion,which is of guiding significance to virtual power plant for the heat price adjustment and low-carbon economic oper-ation.
