| Abstract: | The process data were hard to obtain in existing scheduling methods for steam power system. A scheduling strategy under uncertainty was proposed to deal with the inaccurate data in steam power system. The inaccurate data was presented by triangular fuzzy number, and a fuzzy scheduling model was established. Then the fuzzy model was shifted to a deterministic mixed integer linear programming (MILP) model by using necessity measures and α-level method. Sensitivity analysis was conducted to identify the effects of the imprecise parameters. An example from a certain petrochemical complex was adopted. Results showed that the power demand was most sensitive in the system. |
