The invention discloses a method and system for determining photovoltaic power generation power. The invention optimizes the radial basis neural network model based on the improved thinking evolution algorithm, and obtains the historical similar days of the forecast day on the basis of considering the weights of each influencing factor, so that the selection of meteorological factors (i.e., influencing factors) is more reasonable; The selection algorithm is more effective; the similar day data and the forecast day meteorological data are used as input, and the improved thinking evolution algorithm is used to optimize the radial basis neural network model to predict the photovoltaic power generation power of the forecast day and determine the photovoltaic power generation power of the day to be measured. By adopting the determination method and system provided by the present invention, errors in determining photovoltaic power generation can be reduced.
Description
technical field [0001] The invention relates to the field of power systems, in particular to a method and system for determining photovoltaic power generation. Background technique [0002] In recent years, China has become the fastest-growing country in the world for photovoltaic power generation installations, and the domestic photovoltaic power generation market is developing from independent power generation systems to grid-connected power generation systems. The power of photovoltaic power generation is intermittent due to the alternation of day and night, and it is fluctuating and random due to weather and other factors. Therefore, it is the development of photovoltaic power generation technology to accurately determine the power of photovoltaic power generation in advance to ensure the stable and reliable operation of the grid during the process of photovoltaic power generation grid connection. top priority. [0003] At present, research on the short-term advance det...
