Abstract: DC microgrid is the high quality electric power system focused on the development of renewable energy resources. The dc distribution system is connected to AC grid, Photovoltaic system and synchronous generator. Moreover, the power is transmitted through dc distribution line and is converted to required AC or DC voltages by load side converters. Those converters do not require transformers by choosing proper DC distribution voltage. The DC power line is 400V. This distributed design of load side converters also contributes to provide supplying high quality power. In this research, the configuration of DC microgrid system, control methods of distributed generation will be presented. Moreover, stand-alone system and grid connected system of DC microgrid will also be expressed. The model of DC microgrid system will be constructed with MATLAB/SIMULINK. Simulation results will be described.
Keywords: DC Microgrid, Distributed Generation, High Quality Power, Converters

1.1 Introduction
Non Conventional energy resources like wind, biomass, tidal /wave and small hydro potential were used due to fast depletion of fossil fuels. A micro-hydro system using natural hydro potential with minimal civil works is a strong candidate in this race. However, the system must be economical, rugged, and user friendly since local communities are often not techno-savvy. Uncontrolled low head turbines are prescribed for such applications [1]-[5], which maintain
generating system, solar electric cell energy has grown rapidly and a popular resource of energy. On like most electricity generating system has footpath of (CO2) produce, either during construction of the system or when in operation. Photovoltaic cell also known as the solar panel is one of the Morden means of generating electricity without producing (CO2) although traces of Co2 could be emitted, due to the mechanical application involves during the contraction of the Photovoltaic system which could

Introduction
Permanent Magnet Generators for wind systems are an integral part of the overall system, converting the mechanical energy from the turbine into electrical energy. But since wind is an inconsistent source of power, the generator must be able to adapt itself to power fluctuations, such as excess or shortage of load. Furthermore, standalone wind systems are provided with batteries which must be kept charged under all conditions when the power is available. Thus, a controller is necessary
presents a voltage and frequency control of wind-hydro hybrid system in isolated locations in which one squirrel cage induction generator (SCIG) driven by a variable speed wind turbine and another SCIG driven by a constant power hydro turbine feeding three phase four wire local loads. The system mainly uses a rectifier and a pulse width modulation controlled insulated-gate-bipolar-transistor-based voltage-source converters (VSCs) with a battery energy storage system at their dc link. The main objectives

Abstract— There is a pressing need to accelerate the development of advanced clean energy technologies in order to control the usage of the fossil fuels
from 40 MW to more than 3,000 MW in the last four years. It is also expected that the distributed generation (rooftop Solar PV) at the consumer end will drive solar power capacity additions given the acute power shortages in several states.
Role of various stakeholders responsible for implementation of rooftop solar PV projects in India is shown below-
During the first phase of the JNNSM from 2010 to 2013, project proponents had to rely on self-financing to kick start projects as they grappled with

RESET Circuit:
Reset is used for putting the microcontroller into a 'known' condition. That practically means that microcontroller can behave rather inaccurately under certain undesirable conditions. In order to continue its proper functioning it has to be reset, meaning all registers would be placed in a starting position. Reset is not only used when microcontroller doesn't behave the way we want it to, but can
