This paper proposes a photovoltaic (PV) system, which exhibits a set of benefits when draw parallels to conventional stand-alone PV system. In the present system, the generated energy by the PV arrays is managed by multi-string step-up converters. Voltage swell and sag is big brain-teasers in power system. Sensitive load has a serious effect on itself due to voltage swell and sag. Dynamic Voltage Restorer (DVR) is a power conventional appliance used in power distribution network. Various equivalent circuit models of a PV cell have been proposed. For obtaining high power, numerous PV cells are connected in series and parallel on a panel, which is a PV module. The dynamic voltage restorer with its excellent dynamic capabilities, when installed between the supply and critical load feeders, Power distribution system should ideally provide their customers an uninterrupted flow of energy with smooth sinusoidal voltage at the contracted magnitude and frequency. A Z-source inverter is a type of power inverter, a circuit that converts direct current to alternating current. The impedance network composed of split inductors and two capacitors. The supply can be DC voltage source or DC current source or AC source. Z-source inverter can be of current source type or voltage source type. Z-Source inverter operation is controlled by multiple pulse width modulation. The output of the Z-Source inverter is controlled by using pulse width modulation, generated by comparing a triangular wave signal with an adjustable DC reference and hence the duty cycle of the switching pulse could be varied to synthesize the required conversion. DVR can be considered to be cost effective when compared with other compensation devices. But the use of DC link capacitor in the conventional DVR will increase the size, weight and the cost of the entire system which inhibits widespread use of DVR The dynamic voltage restorer is one of the modern devices used in distribution systems to protect consumers against sudden changes in voltage amplitude. The simulation results are obtained using MATLAB/SIMULINK software
