In this paper, Newton's law and Euler equation is employed to derive dynamic formulation of a SPE workstation driven by PMSM. The dynamic formulations can be expressed by some independent variables. In order to verify this dynamic formulation is correct, we reduce the flexible model to the rigid one under some assumptions, and adopt the genetic algorithm (GA) to identify all the parameters of the...
The solution of optimal load curtailment for the selected system contingency states is the most important step for the reliability analysis of composite power system. The linear reactive remedial model considering the bus voltage and reactive power constrains was formulated first based on the decoupled AC load flow model. Aiming at dealing with the discrete control variables in the reactive power...
The traditional K-means algorithm is sensitive to the initial points and easy to fall into local optimum. To avoid this kind of flaw, an improved GA-based text clustering algorithm CGHCM is proposed. The new algorithm is proven effective to avoid falling into local optimum and obtains better clustering results.
In this paper, the service restoration problem has been formulated as a multi-objective, multi-constrained, and combinatorial optimization problem. The preferential knowledge of the various objective functions considered herein is known a priori. The first objective function (minimization of out-of-service area) has been kept at the first preference. The objective function of minimization of manually...
