A Study on Enhancing Load Power Factor Effectively Using Load Duration Curves and the Power Factor Sensitivity of Generation Cost

부하지속곡선과 부하역률 감도기법 적용에 의한 효과적인 부하역률개선 연구

In this paper, utilization of load duration curves is presented for analyzing the effect of load power factor and determining the value of load power factor effectively. In addition, the power factor sensitivity of generation cost and integrated costs including voltage variation penalty cost are used for determining the value of the load power factor from the point of view of voltage regulation and economic investment. It is shown through the application to the KEPCO power system that the load power factor can be enhanced effectively and appropriately using the load duration curve.
