This paper discusses the reliability analysis of a hybrid power system including wind/PV renewable energy sources and battery bank for power supply in Yildiz Technical University (YTU) - Davutpasa Campus. The hybrid system is constructed on the roof of Electrical Engineering Department building. The system includes a wind turbine, PV modules, a hybrid charge regulator, a MPPT charge controller, an inverter, battery group and loads. Hybrid system combines several renewable energy sources together, therefore it can achieve high reliable indices rather than a PV/battery system or a wind/battery system. But control strategies of the controller is one of the most imported parameters for reliable operation of wind/PV hybrid system. In this study, the reliability analysis of a wind/PV/battery hybrid system, PV/battery system, wind/battery system are conducted by combining power outputs of the wind turbine and PV modules with battery to obtain reliability indices (LOLE, LOEE, Availability etc.). Also, the influence of two different charge controllers on system performance and reliability indices is presented. The obtained experimental results are examined and presented.
