    Automatic Operation of a Stand-Alone Hybrid Power System with Frequency Regulation by Fuzzy Logic and Binary Control
    (2013-09-20) Manjarres, Pamela Astrid; Malik, Om Parkash
    Hybrid power systems must be self-sufficient in terms of frequency and voltage control due to their islanded operation. A control strategy to combine the operation of a wind generator, a diesel generator, a battery energy storage system and a dump load for frequency regulation is proposed in this thesis. The proposed strategy partitions the control task into two subtasks: a) choosing the element to be operated on, b) providing frequency regulation. A global controller, based on an IF-THEN inference engine, chooses the element to operate. The frequency regulation is provided by separate individual controllers. In this thesis, a hybrid power system has been modelled and the proposed control strategy has been tested. By monitoring the system's power management and frequency, it is shown that the proposed control strategy operates efficiently. The proposed strategy also reduces the number of measurements required and facilitates the integration of renewable energy sources.
