The Optimization of Large-scale Intermittent Energy Power Operation in Monthly and Yearly.

Fossil energy is non-renewable energy. The use of fossil energy power generation does not only increase the consumption of energy but also bring environmental pollution. Wind, light and other renewable energy are rich in China. New energy power generation is beneficial to energy security and sustainable development. Due to the characteristics of regional, intermittent, random and unpredictable of wind and light, large-scale wind power and photovoltaic power in state grid are seriously challenged by the overall dispatch of the power system. Firstly, the paper analyzes and improves the evaluation model of intermittent energy generation capacity by analyzing and processing the real data of a certain province power network. Secondly, the maximum intermittent energy generation capacity can be obtained under the current wind and photovoltaic power installed condition in the province power network in yearly and monthly scales. Finally, the input data of the province power network, which is in accordance with the input condition, is input into the proposed optimization model and the results are credible. In addition, the input data and output results are displayed in visualization formed by graphs, which provides effective guidance to the management of the province power network.
