Credible capacity forming of a VPP with wind, solar, and storage resources
The credible capacity formation is a critical task in the design of a virtual power plant (VPP) and serves as the foundation for maintaining stability between the VPP and the power grid. In this study, an optimal configuration method for distributed generations (DGs) for units within a VPP is proposed, based on the concept of credible capacity. The expected energy not served (EENS) is used as the system reliability index to evaluate the credible capacity of the VPP. To optimize the benefit function of cooperative operation between the VPP and the power grid, cooperative game theory is applied to configure the capacities of the VPP's DG resources—namely, wind, solar, and storage units. Multiple scenarios of EENS and credible capacity were analysed to validate the effectiveness of the proposed approach. The results demonstrate that the method can successfully achieve credible capacity for a VPP by optimally configuring the capacities of individual DG units.
