Step 가변형 MPPT 제어기법과 DVR을 적용한 계통연계형 태양광 발전 시스템

다국어 초록 (Multilingual Abstract)

Grid-connected photovoltaic generator system requires high performance PCS(Power Conditioning System) according to the standard of ‘Distributed Generation Grid-Connected Technology Standards’. This paper presents the MPPT control method which improves output efficiency through fast tracking to the maximum power point of PV and a reduced self-excited vibration. Secondly, in this paper DVR function was applied to PCS to compensate the voltage sag frequently happening for a power system.
The proposed PCS control is analyzed and compared to conventional PCS operating characteristic, the various insolation and loads, and voltage sag condition through PSIM tool. It proves the utility.
