Combined with the genetic algorithm, the construction of the solar power generation monitoring model and the wind power generation monitoring model are optimized. The power generation monitoring model obtains quantitative evaluation indicators of the benefits of solar and wind power generation. Through the neural network algorithm, the solar power generation monitoring model and the wind power generation monitoring model are integrated to achieve real-time and comprehensive monitoring of the dual-energy power generation process. This solves the problem that the existing new energy power generation process is greatly affected by the climate, and the existing technology is difficult to monitor climate change in real time, resulting in the complementary collection station distribution system being unable to coordinate the power generation process of decentralized solar power stations and decentralized wind power stations, affecting the power generation efficiency, and then resulting in the complementary collection station The poor control effect of power distribution, ensures that the method in the present invention can be used for a new energy decentralized power station. The dynamic monitoring standard of the complementary collection station distribution system and its control method can be refined within a more precise range, so that the monitored data becomes a more accurate indicator under the same conditions. The development and application of this method significantly enhances the intelligence level of the complementary collection station distribution process of decentralized new energy power stations.
