Abstract : The worldwide demand for electrical energy is growing incessantly, twice the rate of primary energy consumption. Smart grid is one of the solution for the requirement of present scenario. Power electronics can be the key knowledge to build the following group of the more electrical power structures to support the major developments in energy efficiency, renewable energy integration and smart grid. The unpredictable nature of renewable energy resources due to varying weather settings results in voltage and frequency variations at the interrelated power grid. This paper describes the use of a buck converter for controlling the variable input voltage. Some DC-DC converters for photovoltaic necessitate that the input voltage be controlled while the output voltage is constant. This control is not so obvious and requires converter and regulator design. This paper presents the usage of a buck converter that are appropriate for connecting the solar power plant to the grid. Even though all power controllers have high controlling capability, not all achieve the identical in a bus voltage condition.
