STUDY ON DISTRICT-LEVEL HIGH PEAK DEMAND SHAVING BY ELECTRIC POWER INTERCHANGE UTILIZING PRIVATE LINE

Abstract

Peak demand shaving is an effective way for reducing electricity bills. This paper focuses on an approach utilizing electric power interchange between areas and analyzes its effect from the viewpoint of peak power reduction. The usefulness of power interchange for a certain area has been demonstrated in previous researches, but the general effect has not been verified. In this paper, simulational experiments are performed using various load data, so that the amount of peak demand reduction is evaluated from the viewpoints of the shape of a load curve and the timing of the peak occurrence date.
