On September 12, State Grid Jiangsu Electric Power Research Institute and China Electric Power Research Institute jointly built the first distributed photovoltaic power prediction system
based on all-sky imager in China.
It is reported that the system uses an all-sky imager for the first time to track the rapid changes of clouds, and predicts the operation trajectory of clouds according to the change process of clouds blocking sunlight intensity, so as to realize 4H ultra-short-term high-precision prediction of distributed photovoltaic output; At the same time, the system uses the numerical weather prediction system to realize the 24h short-term prediction of distributed photovoltaic output, and the prediction accuracy meets the requirements
of NB/T32031-2016 "Functional Specification of Photovoltaic Power Generation Prediction System".
It is understood that distributed photovoltaic is close to the user side, simple and convenient installation and operation, no noise, only occupies the roof area, can be convenient to achieve spontaneous self-use, surplus electricity on the Internet, in recent years the state has introduced many measures to vigorously support the development of distributed photovoltaic, distributed photovoltaic development around the rapid development, some areas distributed photovoltaic penetration rate has exceeded 100% (distributed photovoltaic installed capacity and load ratio), distributed photovoltaic power prediction helps the power grid to actively perceive distributed photovoltaic output, according to weather conditions reasonable arrangement of operation mode, Improve the reliability of power supply while ensuring the full consumption
of distributed photovoltaic power generation.
