With the emerging technologies the requirement of clean and sustainable energy has become a challenge for the Electrical Engineers in their day to day life. Recent studies suggest that in the next five decades, large portion of the NonRenewable sources accessible will be diminishing. This is the prime concern for attracting the attention for the enhancement in the performance of the renewable energy sources which abundantly exist in the nature. Wind, solar photovoltaic, and solar thermal power systems are emerging renewable technologies that can be developed as a viable option for the future generation of electrical energy. In this paper, we have considered an autonomous hybrid generation system consisting of Wind turbine generator (WG), solar photovoltaic (S-PV), diesel generator(DG),fuel cell(FC), battery energy storage system (BES), solar thermal power system(STPS) and aqua electrolyzer (AE) for simulation studies. In the power system, the frequency deviations are generally due to deviations in load or generation or both. The comparative performance of the controllers installed to alleviate this frequency deviation for different hybrid systems, is carried out using time domain simulations. In practical, tuning of PI and PID controllers is challenging and time consuming. With the introduction of computational intelligence has opened a new pathway for advanced new generation control process. Here, PSO is used as the optimization method to determine the controller gains for the proposed hybrid system. I. INTRODUCTIONIn the present trends, Electricity plays a vital role in all the aspects of human life. With increasing trends in technology demands more power to be generated through fossil fuel. Thus this increase in power demand leads to ecological imbalance such as increase in carbon emission and global warming. These shifting trends of technology required the necessity for clear, ecofriendly and sustainable energy. Research shifted to the alternative generation sources which are available abundantly in nature such as wind, solar, geo-thermal, tidal, bio-mass, are some of the sustainable green energy sources. Among all the available renewable sources wind and solar are more trending as they have high potential and good efficiency with considerable cost when compared to others. Fuel cell and ultra-capacitors also exhibit similar characteristics and can be considered as green sustainable sources for the future. It is known, that not all the systems can be connected to the grid, some located far form generation stations are to be maintained offgrid. Single source systems such as solar photovoltaic, wind generators, micro-hydro systems, diesel generators, or a combination of above systems called as hybrid generation system are use for delivering the load demand. The hybrid system not only delivers load demand but also includes energy storage systems in the form of batteries. Through this system we can deliver both AC and DC power. Thus, by using proper equipment we regulate the overall performance of the...

The aim of this paper if to show that the great part of the execution time is consumed in computations. So as the number of processors increase, the amount of work done by each processor will be decrease regardless the effect of the number of physical cores used. Still the time taken to solve the computations dominates over the communication time as by increasing number of processors; tasks are more divided so overall time decreases. The total overhead generated from process initializations and inter-process communication negatively affects the execution time. Using MPI, parallelization on five sorting techniques which are selection sort, bubble sort, quick sort, insertion sort and shell sort have been implemented.
