Abstract Modeling, simulation, and performance analysis of an isolated hybrid power system (IHPS) consisting of solar thermal power plant, diesel engine generator (DEG), and wind turbine generator (WTG) are done in this paper. Performance of the studied IHPS model has been studied under two different input conditions, viz. (a) step change in load disturbance and wind perturbation and (b) random change in load disturbance and solar and wind perturbation. For better frequency stabilization of the system, proportional–integral–derivative (PID), integral–tilt–derivative (I-TD), and tilt–integral– derivative (TID) controllers are used (one at a time) for controlling governor of the DEG and pitch of the WTG. To obtain better performance for the studied IHPS model, the controller gains are tuned by using quasi-oppositional-based whale optimization algorithm. A comparative dynamic response of frequency deviation profile has been carried out under individual presence of PID, I-TD, and TID controllers. The transient responses of the system pertaining to step and random changes in the load disturbance and solar and wind perturbation are plotted and analyzed. It is revealed from this work that the performance of the proposed TID controller is better than the other controllers for this specific application.

1 Introduction 1.1 General The energy demand has been increasing continuously during the last few decades. Due to the rapid industrial development with degradation of fossil fuels, the living environment has been polluted and destroyed. For the global environmental reasons, the renewable energy sources (RESs) have been increasingly adopted as new sources of energy worldwide. The RESs (like wind energy, & V.

photovoltaic cells, hydro, tidal, geothermal energy, and solar thermal energy) have become a major source of power generation by combining them in various hybrid models to fulfill the increasing energy demand as well as to reduce the level of air pollution index. The wind turbine generators (WTGs) are suitable for isolated area where availability of grid power is of great concern (Lalor and Mullane 2005). Among all the available RESs, the most promising and viable option for electricity generation is from solar power. The basic mechanism for solar thermal power plant (STPP) is the conversion and utilization of solar
