Simulation & Analysis of Dc Micro Grid with Power Quality Improvement

Abstract

In the evolving era micro grid is the core area in all power fields. Now a day’s DC micro grid system have haggard additional attention because of, the rising use of dc energy, energy storing system and loads in control system Managing of power and energy are the growing qualities adopted by researchers present days. The DC Micro grid is more reliable than AC because of less complex structure, cost is low, and control scheme is easy compare to AC Micro grid system. Main aim of this topic is analysis of different power quality issue, Structure and operational mode of DC Micro grid. Distributed generation with renewable sources is becoming a potential trend in technology. DC load have proliferated quickly on the market nowadays and DC micro grids with renewable energies are existence made a possible solution to chance the growing demand for energy. DC Micro grid system connected with PV array supplying power to the DC bus by the DC-to-DC boost converter. Duty ratio of this converter is control by P&O algorithm. And boost converter boosts up the PV array voltage. This simulation able to cancel out the photovoltaic voltage oscillations. It provides smooth power flow using Shunt Active Power Filter.
