摘要：A battery Energy storage system (BESS) based voltage and frequencycontroller (VFC), for an Autonomous Asynchronous Generator (ASG) driven by anuncontrolled pico hydro turbine used in constant power mode, is presented in this paper.Excitation of the asynchronous generator with capacitor bank enables it to generaterated voltage at no load. The additional reactive power demand of the ASG on load andthat for the load itself is provided by the VFC. The proposed controller has thecapability of harmonic reduction, load balancing and load leveling along with voltageand frequency control. The VFC has been realized using an IGBT based currentcontrolled voltage source converter (CC-VSC) having a battery at its DC link. A simpleand effective linear control scheme using SPWM control has been used to control theCC-VSC. This control scheme is easier to implement on hardware than the otherreported schemes, as it involves only linear PI controllers. The effectiveness of theproposed controller for an autonomous generator is demonstrated by simulation onMATLAB platform
