Abstract: With the accelerated development of the new energy system, the market-oriented and continuous participation of virtual power plants (VPPs) in grid interaction has become a crucial means to enhance the regulation capability of the new power system. To address the optimal operation under continuous market-based regulation, this paper proposes an optimized operation method for VPP that considers proactive recovery of residual available regulation capacity. First, based on the regulation and rebound characteristics of VPPs, the proactive rebound effect on the recovery of residual available regulation capacity is analyzed, and an equivalent energy storage regulation model incorporating proactive recovery is constructed. Second, based on this model, a market-based operation framework integrating electricity spot, peak regulation, and frequency regulation markets is established, along with a joint optimization model. Finally, case studies are conducted to validate the proposed method. Simulation results demonstrate that the proposed approach contributes to ensuring the continuous and stable operation of VPP in market participation while enhancing operational economics. The impact of VPP participating in different markets on operational costs is analyzed, validating the effectiveness and adaptability of the proposed method.
