This paper presents the Fractional Order Proportional-Integral-Derivative (FOPID) controller for Automatic Generation Control (AGC) of an interconnected twoarea solar-thermal deregulated power system. In this investigation, the thermal plants are considered with reheat tandem compound steam turbine rather than steam turbine dynamic model parameters are thought to be consistent. Concentrated solar power can store vitality in the type of thermal energy. The stored thermal energy can be utilized to produce electricity in the absence of solar irradiance. Thus, AGC of a multi-area power system incorporating solar thermal power plant (STPP) is vital for these examinations. A FOPID controller is an established PID aside from its derivative and integral orders are fractional numbers in place of being integers. The control parameters of FOPID controller are tuned utilizing Lightning Search Algorithm (LSA) and its execution is contrasted and Proportional-Integral (PI), Proportional-Integral-Derivative (PID) controllers based AGC loop. A sophisticated application of Redox Flow Batteries (RFB) coordinates with Interline Power Flow Controller (IPFC) for the improvement of AGC loop of a two-area solar-thermal power system is also considered. Simulation reveals that the proposed FOPID controller tuned with LSA algorithm liven up the dynamic output response of the test system as far as less pinnacle deviation and settling time of area frequencies and tie-line power oscillations in various exchanges of the deregulated power system. The execution of the RFB and IPFC unit captures the underlying fall in frequency and additionally the tie-line power deviations after a sudden load unsettling influence.

This work deals with simulation of hysteresis controlled single phase AC-AC converter for wind generation. The AC output of the wind generator is converted into DC using three phase uncontrolled rectifier. The output of the rectifier is filtered using a Z-network. The output of the Z-network is applied to the single phase inverter. The single phase inverter feds an induction motor load. Matlab simulink model for wind generator system is developed and simulation studies are successfully performed. The simulation is done using MATLAB and the simulation results are presented.
