Optimization Strategy for Wind-Solar Complementary Energy Storage Capacity Leveraging Photovoltaic Virtual Energy Storage

In this study, we present an integrated optimization model for configuring energy storage capacities in wind-solar energy systems, utilizing an innovative approach of Photovoltaic (PV) Virtual Energy Storage (PV-VES). This model aims to mitigate the high costs associated with conventional electrochemical storage solutions by integrating cost-effective PV components. The proposed optimization framework constructs a cost-minimization objective function, considering the operational characteristics and constraints of wind turbines, PV arrays, and energy storage units. By calculating the optimal installation capacities for both electrochemical and virtual energy storage, the model provides selective cost advantages in investment for renewable energy storage infrastructures. The results demonstrate that PV-VES can enhance the economic feasibility of wind-solar complementary storage systems.
