Power sustainment is the future goal of every developing country. To attain Power
sustainment, alternative way of energy should be invented.Renewable energy research is
becoming more and more famous during these days due to the fast depletion of fossil fuels.
Photovoltaic system (PV) have massive potential source due to the lavishness of solar energy.
Maximum Power Point Tracking (MPPT) algorithm is mainly needed to keep the PV system
operated at optimal point. MPP in a PV system improves the overall system utilization
efficiency with maximum power. When the Power Output of PV System is delivered to Grid
there needs to face lot of problems arise in it. Voltage and frequency fluctuation associated
with renewable integration have been well identified by power system operators and
planners.ES can be connected in series with Critical load and and In this paper discussed
about the Electric appliances with the electric springs embedded can be turned into a new
generation of smart loads, which have their power demand following the power generation
profile. ES can obtain power stability independent of communication technology. ES can
mitigate the voltage and frequency fluctuation caused by Solar insolation variation, load
fluctuation, and generator tripping wherever it is installed in the micro grid.The proposed ES
and modeling of PV-Grid system are simulated in MATLAB 2014Ra Simulink Tool.
