Research on Power System Dispatching Operation under High Proportion of Wind Power Consumption

For the multi-energy power system composed of thermal power, wind and a pumped-storage station aiming at minimizing coal consumption grid, an optimal dispatch model is established in this paper. Its advantage to allow grid accept high proportion new energy while ensuring demand. The dynamic programming method used solve problem. In solution process, traditional improved by introducing penalty function value state variable, which can ensure reliability supply achieving optimization goal, as well realize full utilization energy. Using example systems with storage mode considering relevant constraints after heating transformation plant, our built solves these challenges. results show that when maximum pumping reaches 1138 MW generating 755 MW, curtailment rationing during off-peak period be reduced from previous 58,158 MWH 46,838 almost 0, peak 77,656 53,780 so flexible operation grid.
