A Network-Oriented and Economically-Viable Power Dispatch Coordination Scheme for Battery-Integrated Solar Photovoltaic Systems

Integration of battery energy storage systems with solar photovoltaic provides a perpetually accessible and dispatchable alternative that can be deployed to improve network performance. The high-cost implications of battery energy storage systems (BESS) have necessitated the development of optimal charging/discharging schedules to meet network requirements and preserve the longevity of these resources. This paper presents a novel network-oriented BESS and solar-PV coordination approach to determine the optimal charging and discharging schedules for the BESS system. The proposed approach allows the Solar-BESS integrated system to efficiently provide optimal dispatch service throughout the day while minimizing battery cycles. Further, the optimal power dispatch by the integrated system generates grid benefits and gets remunerated according to its contribution. Implementing the proposed approach on the IEEE European network for different sizes of solar PVs and batteries illustrates that optimal coordination generates significant financial benefits to offset the associated expenses. This research offers valuable insights for system operators planning to deploy battery energy storage systems to improve network efficiency.
