Market-based Operation Method for Virtual Power Plant Considering Active Recovery of Remaining Available Flexibility

Virtual power plant (VPP) play a crucial role in the market-based operation of power systems, contributing to enhanced electricity supply security and the local consumption of renewable energy. To improve the economic performance of VPPs in market operations, this paper proposes a market-based operation method for VPP that considers the active recovery of remaining available regulation capacity. First, an equivalent energy storage regulation model for VPP is developed, accounting for the regulation and rebound characteristics of VPP and incorporating the active recovery of remaining available regulation capacity. Next, based on this equivalent energy storage regulation model, a joint optimization model for the VPP in the electricity spot market, peak-shaving, and frequency regulation markets are established. Finally, case studies demonstrate the effectiveness of the proposed method in reducing VPP operating costs in market environments.
