This paper proposed a new approach combining priority list (PL) with binary particle swarm optimization (BPSO) to solve unit commitment (UC) problem. At first, PL method was used to determine the initial UC, and then the optimization window was determined according to the results, at last the BPSO method was adopted to solve the UC problem within the window. The window is to reduce the computing time...
In this paper, a new approach for unit maintenance scheduling was proposed based on the credibility theory. This approach accommodates two-fold uncertainty: randomness of generator's failure and fuzziness of hydro energy simultaneously. To solve the scheduling problem effectively, a Benders decomposition approach was employed to decompose the optimization model into maintenance master problem and...
Appropriate modeling of dynamic loads is of primary importance in voltage stability studies, especially increasing use of induction machines in both consumption and generation. This paper is mainly related to short-term voltage instability depending on time domain simulation. The actuality of voltage instability research is summarized, and the mechanisms of short- term voltage stability are explained...
With increasingly proportion of distributed generation (DG) in the power system, traditional power system planning has new challenges and demands. The necessity for flexible electric system, changing regulatory, energy savings and environmental impact are providing impetus to the development of DG. Itpsilas critical that the power system impacts be assessed accurately so that DG can be applied in...
