EMTP Implementation of Power Factor Controller in Utility Interactive Photovoltaic System

EMTP를 이용한 태양광 연계 계통의 역률 제어기 구현

A photovoltaic power generation system is one of the ideal clean energy sources increasingly replacing fossil fuel, which has many environmental problems such as exhausted gas or air pollution. As a photovoltaic generation system should meet the requirement to be connected to utility, power factor is an important factor for the high quality of power. This paper implements a power factor controller to improve the power quality of utility interactive photovoltaic system. To verify the effectiveness of the implemented power factor controller, the results by Electromagnetic Transients Program (EMTP) are presented.
