Abstract
This project examines operation model of multiple virtual power plants (multiVPPs), aiming at unified management of the multiVPP through VPP central controller, which reveals the controllability of the VPP as source and load in general. Two operation models will be analyzed in this project. At first, VPP dispatch model and The Second, the game theoretic model for multiVPP dispatch. In the VPP dispatch model, with considering interactive coordination between VPP and energy consumers, a demand response model based on time-of-use pricing mechanism also incentive-based demand response are employed. And then the optimal results of VPP dispatch model are applied in the game theoretic model for multiVPP dispatch. During the process of market competition, the bidding strategy of each VPP is determined by its affordable power output and fuel cost. Finally, taking the multiVPP, which consists of various distributed generations and battery storage devices, as an example, variables including transferred load, compensation capacity, optimal bidding strategy, and profits for each VPP are obtained. It should be mentioned that in this project, the presence of thermal loads (through fuel cell output thermal power and gas boiler) has been considered as essential loads in the power systems, because nowadays, the responsibility of the supply of the thermal loads is in the hands of power system operator. From the analysis of the results, the method serves as a foundation for dispatch of multiVPP.
