基于全局向局部运行空间投影的多级调度协同模式

Multi-level Scheduling Cooperative Mode Based on Projection from Global to Local Operating Space

随着电力市场改革的推进,华东区域各省级市场均已进入试运行阶段,为统筹兼顾现货市场平稳运营与区域电网安全运行,迫切需要研究更高效的网省协同运行机制。首先,分析了现货市场环境下网省调度协同模式的挑战与改进思路。然后,构建了区域电网调度可行域与省市调度可行域模型,提出可行域模型的降维与线性化处理方法。在此基础上,提出了基于调度可行域的网省协同优化运行机制,重点对网省两级协同运行的业务流程、省市可行域的计算方法进行了探讨。最后,通过区域电网的算例分析,验证了调度可行域模型与两级市场协同运行机制的有效性。

With the advancement of electricity market reform,all provincial markets in East China region have been in the trial operation stage.In order to balance the smooth operation of the electricity spot market and the safe operation of regional power grid,it is urgent to study a more efficient region-province cooperative operation mechanism.First,the challenges and thoughts for the improvement of region-province scheduling cooperative mode under the background of electricity spot market are analyzed.Then,the feasible region models of the regional power grid scheduling and provincial and municipal scheduling are constructed,and the method for dimensionality reduction and linearization of the feasible region model is proposed.On this basis,a regionprovince cooperative and optimized operation mechanism based on the scheduling feasible region is proposed,which focuses on exploring the business process of region-province two-level cooperative operation and the calculation method of provincial and municipal feasible regions.Finally,the effectiveness of the scheduling feasible region model and the two-level market cooperative operation mechanism is verified through the analysis of regional power grid cases.
