Abstract
Electricity is most versatile and widely used form of energy. With the fast development of world, the conventional fossil energy sources are rapidly declining and ever increasing consumer demand is rising. So the renewable energy has become the alternative source of fuel. To deliver the growing demand for power as well as providing a stable and sustainable supply of electricity is a heavy stress on today’s grid. The growing worldwide population is dynamic and will create even greater increase in demand for electricity. To rectify this Smart Grid pays way to deliver the Growing demand for power and to minimize the increased complexity of power grids. Smart Grid integrates modern technologies and renewable energy resources in to future power grid in order to supply more efficient and reliable electric power. It aims in describing the development of stable operation of power grid during the integration of different renewable energy sources with the power grid. The main advantage of the proposed system are best intelligence, auto balancing, self-monitoring of power grid that accepts any source and transforms it into consumer end use. The proposed method integrates the renewable energy sources like wind, solar power and supplies the power to the load. In addition the load can also be supplied by the AC grid. If the supply from the renewable energy sources not meets the demand, the load can fetch power from the AC grid. If the power produced by renewable energy sources is more than load demand, it can be connected to grid in further. These control actions are done with the help of controller which uses Model Predictive Control (MPC) technique.
