The Impact of Coordinated Configuration of Photovoltaic, Energy Storage, and Grid Structure on the Operational Efficiency of the Power Grid

Le résumé fourni par la source

With the rapid development of renewable energy, the integration of distributed photovoltaic (DPV) and energy storage (ES) will gradually change the structure and operational form of the distribution network. For the coordinated configuration of DPV, ES, and grid structures, a comprehensive coordination planning model based on stochastic optimization is established by comprehensively considering the investment in DPV, ES and distribution network, operation loss, power outage loss, DPV power abandonment loss, and power purchase cost from the superior power grid. Through the iterative optimization of investment decision and operation simulation, the optimal planning scheme that can adapt to uncertain factors is obtained. The simulation results show that the coordinated planning of DPV, ES and distribution network not only effectively reduces the construction quantity of the distribution network, but also enables the equipment operation to maintain a high utilization level, and has obvious advantages in coping with the load peak characteristics.
