针对国际学界提出的电网智能运行中风险限制调度的框架,新建考虑线路阻塞的风险限制调度多步整合模型,包括日前三步整合调度模型、时前两步整合调度模型和紧急调度模型。日前三步整合调度是在日前调度中计入预估的时前、紧急调度的随机信息;时前两步整合调度计入了预估的紧急调度随机信息。随机信息主要考虑风电出力,并作为模型中的随机变量。通过定义线路阻塞条件风险(conditional value at risk,CVa R)值,将线路安全约束转化为线路阻塞风险限制约束,实现线路阻塞的风险限制调度。仿真结果表明:线路阻塞CVa R值的限值与置信水平两个值取值合理时,多步整合调度与传统的日前、时前、紧急三步调度...

Multi-step integration models for risk-limiting dispatch of line congestion in power system were firstly built in the paper based on the risk-limiting dispatch frame of grid smart operation proposed by international academic. The multi-step integration dispatch models consist of three steps integration day ahead dispatch model, two steps integration hour ahead dispatch model and emergency dispatch model. Estimated random information of the hour ahead and emergency state is included in the day ahead dispatch model, which forms the three steps integration day ahead dispatch one, etc. Wind power ...
