Development and Application of Wind Power Dispatch Scheduling in Xinjiang Power Grid

Xinjiang has abundant wind resources and the wind power generation there is growing rapidly in the recent years. However, the difficulties of dispatching wind power have exerted considerable impacts on the security of the power grid. A wind power scheduling mode based on wind power forecasting and acceptability assessment is developed and a wind power dispatch scheduling system considering the local wind resources and the characteristics of the power grid is established on a software platform associated with wind power forecasting and thermal unit commitments integrated together. The grid security constraints and the peak regulation limits of regular generators are weighted comprehensively. By virtue of power control measures, accurate wind power dispatch scheduling is set up ahead of time. The application outcome of the system indicates that the mode can provide perspective guidance for day-ahead generation planning and real-time dispatching.
