독립형 광전지(PV) 전력 시스템은 통신 장비, 특히 실외에 설치된 장비의 잠재적인 전원입니다. 실용화하려면 변환 효율이 높고 수명이 길어야 합니다. 우리는 전기 이중층 커패시터(EDLC)와 납축전지를 전력 저장 장치로 사용하는 독립형 태양광 발전 시스템을 제안했습니다. 이 시스템은 EDLC의 충방전 전력을 이용하여 PV 어레이에서 생성되는 전력의 변동을 완화합니다. 이렇게 하면 배터리 충전 및 방전 주기 수가 줄어듭니다. 시스템의 작동 특성을 시뮬레이션하고 태양광 어레이 불일치 손실, 시스템 변환 손실, 배터리 기여 계수, 평균 배터리 충전 상태 및 최대 방전 깊이를 평가했습니다. 결과는 시스템이 부정합 손실과 배터리 기여도를 줄이는 데 효과적임을 보여주므로 변환 효율이 높은 DC-DC 컨버터를 사용하면 시스템 효율이 향상될 것으로 기대됩니다. 또한 시스템은 작동 중에 평균 배터리 충전 상태를 유지할 수 있습니다. 이는 더 작은 배터리를 사용할 수 있음을 나타냅니다. 최대 방전 깊이는 기존 시스템보다 낮게 유지될 수 있습니다. 결과적으로 제안된 시스템은 더 긴 배터리 수명을 가져야 합니다.

Abstract: Stand-alone photovoltaic (PV) power systems are potential power sources for telecommunications equipment especially equipment installed outdoors. To be practical, they must have a high conversion efficiency and a long lifetime. We have proposed a stand-alone photovoltaic power system that uses electric double-layer capacitors (EDLCs) and lead acid batteries as power storage devices. This system smooths out the fluctuations in power generated by the PV array by using the EDLC's charge-and-discharge power; this reduces the number of battery charge-and-discharge cycles. We simulated the system's operating characteristics and evaluated the photovoltaic array mismatching loss, system conversion loss, battery contribution factor, averaged battery state-of-charging, and maximum depth-of-discharging. The results show that the system is effective at reducing the mismatching loss and battery contribution factor, so the system efficiency is expected to be improved by using high conversion efficiency DC-DC converters. Moreover the system can maintain the averaged battery state-of-charging during operation. This indicates that smaller batteries can be used. The maximum depth-of-discharging can be kept lower than in the conventional system. Consequently, the proposed system should have a longer battery lifetime.
