Abstract:
Virtual power plant serves as an important market players in the construction of new power system, and the reasonable allocation of revenue is essential to promote its orderly construction. In this paper we propose a revenue allocation strategy for virtual power plants that considers the rights and responsibilities of the participants. The primary objective is to maximize the total revenue of the virtual power plant. With the uncertainty of wind power output taken into account, an intraday optimal scheduling model for the virtual power plant is constructed, incorporating distributed wind power, energy storage devices and adjustable loads. The performance of the virtual power plant is simulated under the participation of various participants. The historical credibility, deviation adjustment contribution, and profit growth contribution of participants are defined to assess the contribution of each participant to the overall revenue of the VPP from both the dual time scales of historical performance and the day-to-be-assigned date. An improved Shapley value method, which considers the weighting of the contribution factors, is proposed to allocate the overall revenue of the virtual power plant. This method ensures that the allocation of the revenue achieves a dual impact of both the historical contribution and the day-to-be-assigned date performance, thus motivating the participants to participate in the collaborative control of the VPP. Example results indicate that the proposed revenue allocation strategy can clarify the contribution of each participant to the overall revenue and assessment of the virtual power plant, realize the principle of "whoever provides, whoever profits", and ensure the fairness and reasonableness of the revenue allocation of each participant in the virtual power plant aggregation.
