Analysis on tie-line control of grid solar system

The human activities contribute to the global warmi ng of the planet. As a result, every country strives to reduce carbon emis sions. Numbers of efforts are being undertaken by the Governments around the world to explore alternative energy sources and to achieve pollution reduction. Solar e lectric or photovoltaic technology is one of the biggest renewable energy resources to generate electrical power and the fastest growing power generation in the world. The main aim of this work is to analyze the interface of photovoltaic system to the load, the power electronics and the method to track the maximum power point (MPP) of the solar panel. Then main emphasis is to be placed on the photovoltaic system , the modeling and simulation photovoltaic array, the MPP control and the DC/DC converter will be analyzed and evaluated. The step of modeling with MATLAB and Simulink of the photovoltaic system is shown respectively and simulation results are provided.
