As the interconnection of power grids, failure of single component could propagate out, and because of the scale of the power system, it is almost impossible to analysis all failure patterns. Traditional methods for online cascading analysis could face almost unsolvable obstacles on computational burden and accuracy. This paper discusses the mechanisms of early warning of cascading blackouts. Researches...
With distributed generation technologies becoming more and more sophisticated and the progressive development of distribution automation technology, the application of distributed generation in distribution power system is gradually broad and diverse. This paper first lists the common operation modes of distributed energy sources, then analyzes the different characters of distributed generation running...
This paper presents a comparison of a differential evolution (DE) algorithm and a modified discrete particle swarm optimization (MDPSO) algorithm for generating optimal preventive maintenance schedules for economical and reliable operation of a power system, while satisfying system load demand and crew constraints. The DE, an evolutionary technique and an optimization algorithm utilizes the differential...
This paper describes a digital computer program that is one of a set to be used in planning the most economic pattern of electric power generator purchases for a 20-to 30-year period. The purpose of this particular program is to determine in which future years new generating capability will be required. Alternatively, if the years of unit installation are to be specified, then the program will calculate...
