This paper provides a study of the design for stand-alone photovoltaic (PV) system to provide electricity for the purposes required for family in Iraq .the system is created on the data of solar radiation site studied as well as electric load data for the houses in the same site. proposed Maximum Power Point Tracking (MPPT) control loop and using the best techniques Perturb and Observe (P&O) Algorithm extracting maximum power from PV module under different solar irradiation, To control the process of charging battery and discharging the battery in different cases use PID control to stay the input dc voltage const ant at steady state and tuning parameters was done through the use Particle Swarm Optimization (PSO). The proposed method is applied to generation 3.5 kW, 210 V, 50 Hz, three-phase standalone PV system. A software simulation model is developed in Matlab/Simulink.

“…When the dc voltage at common dc link (V dc ) is greater than the battery voltage (V bat ) and the state of charge (SOC) is less than 60% then the bidirectional converter operates in buck mode that is battery starts charging and if V dc is less than V bat then the converter operates in a boost mode that is the battery starts discharging through the load [11]. The controlling is explained through the block diagram given in fig.…”

As the fossil fuels are non-renewable sources of energy and depleting with time, the focus moves towards the renewable sources of energy like solar and wind energy. The renewable sources of energy do not deplete with time and fulfill the increasing demand of energy. In this paper hybrid solar PV system and wind generation systems are implemented using MATLAB/SIMULINK with battery storage in a microgrid, to supply the power demand, at remote locations. Battery storage system is used due to the intermittent nature of the solar and wind energy and thus making this generation system more reliable. The implemented model consists of solar PV, wind turbine connected to a permanent magnet synchronous generator and the output of both the systems is connected to a common DC link through a BOOST converter. A PWM inverter is used for converting the output of boost converter to provide a 3-phase power to the load. In this system Maximum Power Point Tracking (MPPT) is used for both wind and solar PV system. The simulation results of the implemented system are presented in this paper for different environmental conditions. Keyword: Solar PV system, Wind system, MPPT, BESS, Microgrid I. INTRODUCTIONFossil fuels like coal, crude oil and natural gas are supplying most of the energy. Energy demand is increasing day by day with increase in population. But as fossil fuels are depleting in nature and also produce greenhouse gases that lead to the global warming therefore there is a need to focus on the renewable sources of energy like solar energy, wind energy, geothermal energy etc. Several hybrid models are used by either combining them with the grid or as a standalone system. Hybrid models are used due to the fluctuating nature of renewable sources of energy and in hybrid system of two sources if one source is not available then the other source will supply the energy. In this paper a standalone hybrid system composed of solar and wind is proposed and the hybrid system is implemented using MATLAB/SIMULINK. The solar PV system output is connected to a DC Boost converter to enhance the voltage, wind system using PMSG generator is implemented. The output of both the sources is connected to a common dc link where a battery storage system is also connected which will charge through the output of these sources during the excess generation and battery will discharge and supply the load during the insufficient generation due to the fluctuating nature of these sources. The output from dc source is inverted into ac through PWM inverters. MPPT (Maximum Power Point Tracking Techniques) is used in both solar PV and wind systems to track the maximum power from solar under different solar radiations and from wind under different wind speeds.

“…Em aplicações usando energias renováveis, como eólica ou solar, geralmente são usadas baterias recarregáveis de chumbo ácido para realizar esta tarefa. Para controlar a carga e descarga das baterias, estes sistemas, usam controladores de carga que operam evitando sobrecargas e descargas profundas (SHAW, 2015). Algumas aplicações deste tipo de sistemas são: eletrificação de áreas rurais isoladas, sistemas de bombeamento de água, estações repetidoras de micro-ondas e iluminação pública (PADILHA, 2011…”
