    Abstract

    Due to the fluctuating nature of renewable energy sources, voltage stability and power management become the main concerns of a hybrid power generation system. Therefore, improving power technology and control methods are necessary for improving power efficiency. An integrated Cuk-Sepic multi-input single-output (MISO) converter is developed for hybrid renewable energy applications in this paper, which acts as a power electronics interface to integrate various power sources. This converter can be operated individually or together depending on the presence of available sources in the vent of failure of one of the sources, which makes the system more reliable. Additionally, a Fuzzy Supervisor Controller (FSC) is presented to effectively regulate the power flow while keeping the output voltage stable. By applying the proposed control schemes and an energy storage unit, the developed structure allows the renewable energy sources to work in maximum power point tracking (MPPT) operation mode. The performance of the proposed integrated control strategy under dynamic outdoor conditions is evaluated and compared with the traditional method, which shows improved power-sharing and power flow control capability in a hybrid power system.
