Virtual Power Plant Optimization Decision Method Considering the Interaction Between Combined Cooling-Heating and Power and Electric Heating Equipment

The energy Internet revolution has greatly improved users' flexibility in using energy. The extensive use of electric heating equipment(EHE), combined cooling heating and power(CCHP) and many other equipment enables the flexible conversion of different types of energy at the user side, which has widened the regulation scope for virtual power plant(VPP) in participating in the demand response of large power grid. In this paper, a flexible operation technology framework of VPP considering the interaction between CCHP and EHE is proposed and the operation characteristics of CCHP and EHE are emphatically introduced. Then an optimal decision model for VPP considering the interaction between CCHP and EHE is proposed which could fully satisfy the user's comprehensive energy demand and aims at maximizing the operation efficiency of VPP. Finally, a case study based on the actual data of an industrial park in China is used to prove the validity of the proposed method.
