【 摘 要 】

New energy sources such as wind power are developing rapidly, which contributes to the green development of society and economy. However, wind power is a fluctuating power source with uncontrollable power. It is necessary to predict the power capacity of wind power generation and reasonably allocate the operation mode of thermal power units to realize the power grid's absorption of wind power. By analyzing the influence of the wind power output prediction error on the grid area control error(ACE), the number of inputs of the thermal power unit's automatic generation control(AGC) mode is dynamically adjusted in real time to meet the load adjustment rate required for the ACE change. The results show that this method can effectively improve the load regulation capacity of the power grid, improve the consumption capacity of wind power and other new energy sources, and ensure the stability of the power grid frequency.
