摘要

提出了电力系统运行的模糊模型。负荷和代的不确定性用模糊数建模。系统在已知(不确定)注入下的行为由直流模糊潮流模型处理。系统最优(在不确定的情况下)运行是用线性规划程序计算的，其中问题的性质和结构允许使用一些有效的技术，如dantzigg - wolfe分解和对偶单纯形。得到了系统运行的模糊成本值和支路潮流和发电的可能性分布。一些风险分析是可能的，因为系统稳健性和暴露指数可以推导，对冲政策可以调查。

Fuzzy modelling of power system optimal load flow

A fuzzy model for power system operation is presented. Uncertainties in loads and generations are modeled as fuzzy numbers. System behavior under known (while uncertain) injections is dealt with by a DC fuzzy power flow model. System optimal (while uncertain) operation is calculated with linear programming procedures in which the problem nature and structure allow some efficient techniques such as Dantzig-Wolfe decomposition and dual simplex to be used. Among the results, one obtains a fuzzy cost value for system operation and possibility distributions for branch power flows and power generations. Some risk analysis is possible, as system robustness and exposure indices can be derived and hedging policies can be investigated.<>
