This paper proposes a sequential loading method, which finds the hourly changes of frequency and optimal load distribution between power stations. The method solves to minimize the aggregate cost in the electric power system (EPS). The method also calculates the surplus or deficit of an active power in EPS, hourly power flows of each transmission lines, active power losses in the networks. Computed...
This paper proposes a novel regenerative braking control system of electric wheelchairs for senior citizen. ldquoElectric powered wheelchairrdquo, which generates the driving force by electric motors according to the human operation, is expected to be widely used as a mobility support system for elderly people. This study focuses on the braking control to realize the safety and smooth stopping motion...
Paper presents the difficulties of existing anti-emergency automation when operating in islanded power system. The operation of existing anti-emergency automation is apprized from the point of view of elimination of active power deficiency or surplus. Shortages of existing anti-emergency automation as well as necessary areas for improvements are shown. New method for estimation of active power deficiency...
Several designs of flexible electric power delivery system have been proposed to meet the demand for unbundled power quality. One such conceptual design is the so-called quality control center (QCC), where distributed generators (DCs) are expected to play a central role. In this paper, a new system stability control strategy is proposed by taking the advantage offered by the QCC. A dynamic model is...
