Study On Active Power Optimum Dispatching Of Large Wind Farm

With increasing wind power capacity, to achieve large-scale wind power is an inevitable trend of wind power development. However, since the wind is a volatile, random and intermittent strong clean energy, resulting in wind power dispatch is different from conventional energy sources. And the wind farm is an organic combination for a large number of wind turbines, wind farms under active intelligent distribution layer hair is also included in the grid scheduling section. Based on this, the active allocation and scheduling for grid scheduling side active layer wind farm work, the main work is summarized as follows:(1)Wind turbines and wind farms to expand research, in-depth analysis of the operating characteristics of wind turbines, wind turbine control strategy, control strategies of wind farms.(2)For adjustment of status output of wind farms, based on the priority of law limit output control, increase output under the control of the wind farm field power distribution methods were studied. According unit running on the unit set classification to determine control decision parameter adjustment for each output state, established inside the unit output control priority sequence table, combined with the priority sequence table design wind farm control module active control strategy.Active power control mode.(3)Analysis of wind power and the large-scale use of wind power to the grid operation mode and network-related problems. To develop wind power scheduling active control strategy design principles. Under the guidance of design principles, combined with large clusters of Gansu wind power project example, active control of the wind farm investment and stopping criterion and in-depth study of the control logic. Finally, the combination of work experience summary analysis of wind farm site AGC testing.
