摘要: |
考虑风电出力的预测误差和负荷功率的预测误差具有随预测时间尺度的缩短而减小的特点,以及电力系统旋转备用容量的配置离不开机组组合,建立了多时间尺度下协调机组组合的含并网风电电力系统旋转备用预留容量的优化模型。对该模型的求解,先采用优先顺序法求取各机组的启停机顺序,再通过粒子群算法滚动计算求解得出不同等效旋转备用容量水平下所对应的系统最经济调度计划。通过利用不断更新的风电出力预测和负荷预测结果信息来调整调度计划,在保障系统可靠性达到要求的前提下,减少含风电电力系统旋转备用容量的配置,从而提高风电并网后电力系统运 |

Abstract: |
Taking into account wind power output prediction error and load forecast error reducing along with the timescales shortening, as well as spinning reserve capacity of the power system configuration inseparable from unit commitment, this paper establishes a mathematical model of power system spinning reserve configuration for unit commitment in multiple time scales. Priority method is used to solve the startup and shutdown sequence of each unit, then the PSO is used to solve the most economical scheduling corresponding to different equivalent spinning reserve capacity. On the condition that the reliability of the system can meet the requirements, by use of continuously updated information of wind power output prediction and load forecast to adjust the scheduling plan, it reduces the configuration of power system spinning reserve capacity and improves power system economic operation with wind power grid connected and absorptive capacity of wind power. |
