Solar energy is the major source of power. Renewable energy sources such as wind-turbine and photovoltaic power generators may make the power grid unstable due to their output fluctuations. Battery energy storage systems (BESSs) are being considered as a countermeasure for this issue. This study presents a battery storage system (BSS) based on a cascaded H-bridge inverter applied to a medium-voltage grid. The BSS is composed of eight equal series connected H-bridge converters, without bulky transformers, for connection to a distribution grid. The BSS is able to keep working even with a failure of one of its converters. Inverters of PV system based distributed generation (DG) are subjected to wide changes in the inverter input voltage, thus demanding a buck-boost operation of inverters. Further the inverter size, weight, and cost are is increased. It is designed transformer less inverter that can be operated over a wide dDCc input voltage range, making it suitable for distributed generation applications.

The work focuses on the photovoltaic array fed water pumping system utilizing induction motor with the model developed in PSIM. The solar panels to absorb and convert sunlight into electricity. Maximum Power Point Tracking (MPPT) is a technique used to maximize output Power from the PV and finally, a 3- phase induction motor is driven by through it. The pPhotovoltaic array is used to run an induction motor that drives the centrifugal pump. The PV array connected to induction motor where MPPT technique (p & o) and (Inc.) plays an important role that is developed in PSIM and the outputs are observed. The PV system cost for maximizinge the output of a PV system, continuously tracking the maximum power point (MPP) is necessary.
