    Frequency control of isolated hybrid power system using FA optimized controller
    (Department of Electrical Engineering, NITS, 2019) Sharma, Ajnish Kumar
    India has a big populace and very constrained natural assets mainly for meeting its power necessities. If the wishes to hold its momentum of fast increase economy it is possible with a clear strategy for resource utilization, satisfactory use of power alternatives to be had. Power is crucial for development and which means that if India want to move faster than it need to ensure the reliable availability of energy. The existing electricity condition in India is not so pleasant and there is a huge scope of development. Maximum of the energy generation in India is generated by means of conventional power plant. Coal and mineral oil-primarily based energy flowers which contribute heavily to environmental degradation. Adding to this conventional power plant will cause for environmental degradation and inevitable import volatile oil and coal. We have to be judicious on utilization of considerable renewable energy sources available in the surrounding, which include biomass, sun, wind, geothermal and ocean electricity. Due to the inequality in accessing electricity across the region, renewable energy has the possibility of becoming the inspiration for us for energy requirements. Electricity has been universally identified as one of the most crucial inputs for economic growth and human progress. There’s a strong relationship between economic growth and consumption of energy. One hand, increase of a country GDP, hinges on the availability of economic and environmental friendly electricity generation, and on the other hand, the extent of economic improvement is proportional to the electricity demand. If India has to maintain its growth it has to boom its use of renewable resources and reduce its dependence on conventional energy sources. The frequency of small power system deviates for sudden adjustments in load or generation or the both. Automatic generation control of an autonomous hybrid generation system such as wind turbine (WT), solar photo voltaic (PV), diesel engine (DEG), battery energy storage system (BESS), have been taken into consideration for simulation research. The comparative performance of the controllers employed to alleviate this frequency deviation for isolated hybrid systems, is executed using time domain simulation. In general, controllers (PI or PID) are use which is tuned manually which is difficult and time tacking. The computational intelligence has opened paths to a brand new technology of superior method. Right here, Firefly algorithm(FA) is used for optimization of controllers ‘The advantage of the proposed hybrid structures with fractional order PID controller has been shown, the simulation outcomes reveal the effectiveness of the FF based fractional order PID controllers in reducing settling time, overshoot and oscillations. The results are as compared with FF optimized PID controller. Application of fractional order PID (FOPID) controller to an automated frequency control of isolated hybrid power system is studied. Fractional order PID controller's orders are fractional numbers rather than integers. Design stage of this controller includes figuring out five parameters. This paper employs Firefly algorithm for optimization. FA is an advanced search method that has proved to have very high efficiency. A unique fee feature is described to facilitate the manage approach over both the time domain and the frequency-area specifications. Comparisons are made with a PID controller and it's proven that the proposed FOPID controller can give quite good robustness domain simulation.
