Day-ahead generation scheduling with wind power based on the coordination of source and load

A new day-ahead generation scheduling with wind power based on the coordination of source and load is proposed in this paper. First, the effect of time of use (TOU) pricing on day-ahead economic scheduling program is analyzed. Secondly, to consume more wind power in the day-ahead generation scheduling, the TOU pricing problem is combined with the unit commitment (UC) problem. The problem of uncertainty of wind power is also dealt with by scenario method, which transforms the stochastic optimization problem to a deterministic one effectively. Finally, the proposed method is tested on a provincial grid. The simulation results indicated that the coordination of source and load can benefit to the consumption of wind power and consumers. The operation cost of power system is also decreases significantly.
