Hybrid Energy Storage System Micro Grids Integration for Power Quality Improvement using various Controller

Renewable energy technologies gives us much cleaner, abundant energy gathered from self-renewing resources such as the sun, wind etc. Increase in power demand leads to increase in powerfailure. Hence, renewable energy sources acts as constant load provider. A converter topology for hybrid wind/photovoltaic energy system is proposed. In reality, combining both solar and wind power sources provides us with much needed power generation. By using Renewable energies we have getting advantages of nil fuel cost and environmental impacts got reduced. In this paper, we will see a SEPIC converter topology is used for the hybrid power sources. Two inputs, one from wind energy and another from solar PV panel are given to the converter and maximum power is extracted by using fuzzy logic maximum power point tracking method. Depending on the availability of the energy sources this configuration allows two sources to supply the load separately or simultaneously. The output is given to inverter which converts dc to ac and then applied load. This hybrid energy is given to the three phase inverter. It will convert that DC voltage into AC voltage. This AC voltage is given to the load. The sinusoidal PWM technique is applied to the inverter to control the output voltage and the Fuzzy controller compensates reactive power in the grid. Simulation is carried out in MATLAB/ SIMULINK. Here in this paper, we will prove that fuzzy based controller is best for controlling the production and supplying of power in the bus by comparing with other controllers namely PI, Hysrterisis.
