ANALYSIS OF A MICRO GRID CONNECTED LOW VOLTAGE DISTRIBUTED GENERATION SYSTEM

With the continuous development of economy and social progress, the social requirement of power network is more and more high. This paper, as a basis research of distributed generation, proceed mainly from the impact of distributed generation on power grid, detailed fine analysis of the influence of all kinds of distributed generation on power network adverse, including power system stability, power quality, power supply reliability effect. In order to avoid these adverse effects, we combining the distributed grid technology and smart micro grid, put distributed generation as a branch of the micro grid that can be ideal to connect grid and can avoid most of the problems mentioned above. Distributed intelligent micro grid system uses variety of new energy supply, it is a comprehensive model of power electronic technology, distributed generation, renewable energy power technology and energy storage technology .The paper provides a reference for the use of future distributed power generation. Technological advancements in the field of renewable energy power generation are made it possible to think of micro grids. This technology is providing to be beneficial in making localized areas self-sufficient in power management. Being at low voltage (440 V Line-to-Line (L-L)-11kv) for Three Phase and 230 V for single phase networks, the micro grid can deliver needs of domestic as well as small scale industries (SSI) which together consume a few kilo watts (KW) of power. This paper focuses on single phase grid connected system catering the needs of few domestic as well as small scale industries. Solar energy coupled with a storage system is considered here so that the reliability of the system is improved. MATLAB R2015 a Simulink is used to simulate the model
