Retracted: Research on Power System Active Power Scheduling Strategy Adapted to Large-Scale Wind Power Grid-Connected

The vigorous development of wind power has promoted the optimization of China's energy structure and energy conservation and emission reduction of power systems. Large-scale wind power access to power systems increases the uncertainty of power system operation. The uncertainty of wind power power and the poor predictability pose challenges to traditional active power optimization scheduling based on load forecasting. This paper starts with the influence of wind power uncertainty on the active scheduling of the system. The proposed intra-day ultra-short-term active power optimization scheduling strategy considers the economic and safety of the system operation, and solves the multi-period optimization problem in the forward-looking time. The scheduling provides an initial strategy and performs rolling optimization with actual scheduling results and new prediction information as feedback information. The strategy links the information of the daily scheduling time scale and the real-time scheduling time scale, and can effectively adapt to the influence of disturbance factors such as prediction information fluctuation on system scheduling.
