Data show that as of the end of February, Zhejiang new energy power generation capacity was 41.48 million kilowatts, of which distributed photovoltaic installed capacity was 28.78 million kilowatts, accounting for 80 percent of the total installed photovoltaic capacity. "there are a wide range of distributed photovoltaic points, superimposed distributed photovoltaic intermittent, volatility and other power generation characteristics, the use of digital means can effectively improve the level of intelligent management of distributed photovoltaic." Yan Jiaxiang, director of the product operation room of Zhejiang Energy big data Center. Nowadays, relying on the provincial energy big data center, Zhejiang correlates the data of power grid equipment and distributed photovoltaic power stations, develops a distributed photovoltaic capacity analysis platform, and constructs an accurate prediction model of distributed photovoltaic generation output. effectively improve the level of observable, measurable and controllable management of distributed photovoltaic. "the distributed photovoltaic capacity analysis platform can accurately predict key data such as power generation, annual power generation efficiency and annual equivalent hours of photovoltaic stations, providing strong guidance for the operation and management of our power plant." Zhejiang Changshan Tongjing Photovoltaic Power Station Director Zhu Jianwei said. Relying on this platform, Zhejiang has achieved one-minute observation of distributed photovoltaic output. In addition, relying on Zhejiang Energy big data Center, Zhejiang also has data analysis support in distributed photovoltaic development planning. At present, Zhejiang has realized the calculation of the open capacity of nearly 300000 distributed photovoltaics that have been connected, providing a theoretical basis for the expansion of the distributed photovoltaic industry, effectively guiding distributed photovoltaic investors to invest scientifically, promoting local consumption of new energy, and improving the efficiency of new energy utilization.
