On December 21, the Key Technology for Large-scale Photovoltaic Power Generation Project Ended by Qinghai Electric Power Company under the State Grid was evaluated by the expert group of the Provincial Science and Technology Department.
The expert group agreed that the research results using energy storage technology to improve the credibility and scalability of photovoltaic power generation capacity, reducing the abandoned photovoltaic power, and in the optical storage model, optical storage optimization coordination and scheduling made technological innovation , The research achievement reached the international advanced level.
Relying on abundant solar energy and lithium resources, at present, our province is building 10 billion kilowatt-class photovoltaic power generation base and 100 billion yuan lithium battery industry chain, and the provincial energy storage industry has enjoyed a good development situation. Photovoltaic capacity, but also to promote the healthy development of light, storage and power grid.The results for the coordinated development of photovoltaic, energy storage and Qinghai power grid in Qinghai Province to explore a practical way, with broad prospects for development.
The results of this research are based on the research on the mechanism of light storage and power generation, energy storage optimization, light-storage combined operation and dispatching and the operation economy of light storage power station. In view of the problem of large-scale centralized photovoltaic power generation output fluctuation and dissipation, Excavating the output characteristics of photovoltaic and energy storage and generation, setting up a network-source-storage simulation system including the detail model of optical storage, optimizing the reliability model of the photovoltaic power plant after adding energy storage, and putting forward the method and evaluation of capacity optimization of energy storage system Indicators, developed a joint storage and dispatch management system to achieve the first commercial operation of large-scale optical storage stations, and achieved remarkable results in stabilizing fluctuations and reducing light and ensuring the stable operation of the grid.
