Peak Load Capacity of Large-Scale Wind Power AC/DC Transmissioning Line Optimization Method

Due to the intermittent and anti-peaking nature of wind power output, if the power dispatch is aimed at minimizing the amount of wind output, it may cause the thermal power plant output to seriously deviate from the economic operating area, resulting in an increase in system coal consumption. Combining the relevant policies of renewable energy generation in China and the basic objectives and guidelines for energy-saving generation scheduling, a corresponding optimization scheduling model was constructed for two kinds of generation scheduling models based on the minimum amount of abandoned air and the minimum energy consumption; and wind power was studied and proposed. The economic evaluation indicators of system power generation dispatch include wind power utilization, available wind power unit value, system energy consumption and peaking capacity, etc.
