大规模风电场的接入，提高了发生事故时所需的补偿容量，但没有改变其发生概率，导致传统含风电系统调度模式的备用闲置现象更加严重。为此，针对风电随机性与波动性，建立了体现发电机侧备用与柔性负荷经济特性的成本模型，通过风险管理协调优化，使二者经济特性达到互补的效果，并将其引入到传统含风电场电力系统调度模型中，采用细菌群体趋药性算法对所提模型进行求解。以经典的10机系统和1个大型风电场为例进行仿真研究，验证了所提调度模型的可行性以及优越性。

The large?scale wind farm integration has risen the compensation capacity when the accident happened, but its rate has not been changed. The idle reserve of the traditional dis?patching mode of power system which contains wind power has in?creased. Therefore, considering the uncertainty and volatility of wind power, the cost model which reflects the economic character?istics of the reserve capacity of generation side and flexible load is formulated. These two characteristics are complementary through the coordination and optimization of risk management. This cost model is introduced into the traditional dispatching mode of power system which contains wind power. Bacterial colony chemotaxis op?timization is employed to solve this problem. Case studies are car?ried out on a system which consists 10 thermal generators and a large wind farm. The simulation results demonstrate the feasibility and effectiveness of the proposed model.
