Abstract

In order to improve the consumption of new energy and promote the flexibility transformation of thermal power units, taking the “solar-fired-storage” integrated power generation system as the research object, the Bayesian algorithm was used to optimize the long-term and short-term memory neural network, and a load demand forecasting model on the power consumption side was established. Based on the analysis of the output characteristics of coal-fired power plants （CFPP）, the operation strategy of the “solar-fired-storage”integrated power generation system to stabilize CFPP output fluctuations is proposed. The results show that in terms of thermal performance, the adverse effects on CFPP after being coupled with energy storage can be offset. In terms of output fluctuation characteristics, compared with the original CFPP, the output fluctuation rate of the unit for 7 days of continuous operation is reduced by 7.16%, and the optimization effect is significant.
