Strategi Pengisian Baterai pada Sistem Panel Surya Standalone Berbasis Kontrol PI Multi-Loop

This study discusses the power control strategy in a standalone photovoltaic-battery hybrid system. The life-time of battery will be shorter if is often charged with high current and exceeds its State-of-Charge (SoC). Therefore, method needed to flow on DC bus charging as well SoC so that has long life-time. proposed system uses two dc-dc converters connect photovoltaic (PV) lead-acid batteries load. unidirectional DC-DC converter used interface between PV bus, bidirectional bus. plays role controlling load maintain balance support when available not enough meet multi-loop this study, one loops order output avoid over-charging. Another loop ensure system's at maximum charge current. implemented without requiring any conditions for operate. simulation results show can while maintaining limits.
