Against the backdrop of large-scale integration of renewable energy sources
there is a practical need to simultaneously enhance the system’s capacity support capability and the allocation efficiency of regulation resources. Traditional planning methods struggle to capture the dynamic regulation capabilities and capacity support value of multiple types of units under varying operating conditions. To address the challenges of quantifying the diverse contributions of different types of units in renewable energy bases and the insufficient incentives for regulation resources
this paper proposes a coordinated planning model for multiple types of units in renewable energy bases that incorporates compensation incentives
aiming to achieve the coordinated optimization of capacity and energy allocation. The model introduces a kernel density estimation method to probabilistically characterize capacity demand margins and establishes a compensation pricing mechanism based on marginal capacity contribution. This mechanism guides different types of units to participate in capacity allocation decisions according to their regulation capabilities. Case studies demonstrate that the proposed model can effectively enhance the willingness of regulation resources to provide support and improve system operational flexibility
significantly increasing the level of renewable energy integration. It also provides a quantitative basis for the classified allocation of regulation resources and the refinement of capacity mechanisms.
