Collaborative Planning Strategy of the PV-ES Joint System in Park Considering Multi-user Bidding

Photovoltaic (PV) park equipped with energy storage (ES) can reduce the volatility of PV output and promote the PV consumption. However, the single application of ES restricts the development of PV and ES industry. It is crucial to explore the collaborative planning of the joint system under multiple application scenarios. Therefore, a collaborative planning strategy for the PV-ES joint system in park considering multi-user bidding is proposed. Firstly, the interactive models of various users participating in the park are established according to the user categories. Users can act as electric suppliers or demanders according to their own power supply and demand. They declare prices and electricity to the PV and ES operator in park to participate in the collaborative planning of the PV and ES joint system. Secondly, the objective function is to minimize the cost of the PV and ES operator in park. Finally, based on a real PV park, the simulation analysis is carried out to verify the rationality and effectiveness of the proposed collaborative planning strategy of the PV-ES joint system in park.
