Review of cooperative optimization operation strategies for demand response in photovoltaic and energy storage park

As the penetration rate of renewable energy increases, photovoltaic-energy storage parks (PESPs), integrating photovoltaic (PV) generation and energy storage systems as regional energy units, demonstrate significant advantages in the context of demand response. This paper systematically reviews the collaborative optimization strategies of PESPs and demand response, covering key technologies such as price signal-based mechanisms, multi-objective optimization, and intelligent algorithms. It also deeply analyses existing challenges and proposes corresponding solutions. Future directions focus on emerging technology integration (e.g., AI, blockchain), multi-energy complementarity, and integrated energy management, aiming to provide theoretical reference and practical guidance for high-proportion renewable energy consumption and grid flexibility interaction in PESPs.
