PV System Control using Power Electronic Converters

  M Suneel,  P Chaithanya Kumar

The power electronic converters plays crucial role in conversion and control of the electrical power. The production of solar energy is based on the idea of converting a type of energy mostly solar energy into electrical energy. The most appealing renewable energy source is photovoltaic which transform the solar energy into DC electrical energy. Power electronics converters are used to control frequency and magnitude of the current resultant from the conversion between energies. The objective of this paper is to model and control of transformer-less grid connected PV system with Hysteresis controller which can be used to supply the electric power to utility grid. This system uses two stage conversion process. DC to DC stage which utilizes MPPT technique to extract the maximum power. DC to AC which used to control inverter output by using hysteresis Current controller. The problem of maximum power transferring is enhanced by using Incremental conductance algorithm and phase locked loops are utilized in conjunction to make supply in synchronization with the grid which reduces the two problems described. The studied system is modeled and simulated in the MATLAB/SIMULINK environment.
