This paper presents a stand-alone photovoltaic (PV) system with a hybrid storage unit operation under normal and faulty condition. An energy management method based on the use of a hybrid storage for the solar energy production system is presented. The storage system consists a battery and an Ultra Capacitor (UC) pack. The UCs are used for facing high frequency variation of the load/source, while the batteries are in charge of slow load /source variations. Generally, in a PV system boost converters are used to connect solar panels to the DC bus. These converter allows to achieve the maximum power of the PV source by applying a Maximum Power Point Tracking (MPPT) algorithm. On the other hand, the power electronic semiconductor switch faults are popular in DC-DC converters. In order to improve the micro-grid service continuity and reliability, a fast fault detection method based on the converter current shape and one redundancy based fault tolerant converter for PV source is proposed in this paper. The validity of the proposed energy management and associated control system, the fault detection method and fault tolerant strategy are confirmed by the simulations, HIL and experimental results.
