A reliability study of medium voltage grid with private sector power plants

The number of private sector power plants connected to the national grid has been increasing recently. Those plants with various in sizes may have a positive contribution to the grid. Numerous calculations are carried out in equipment selection and protection setting to integrate the power plant to the grid. Not only these calculations but also a proper operation of a plant are so important in improving system reliability. This is mostly considered as the base case for the worst scenario. In this paper, a reliability evaluation study of private sector power plants connected to an MV grid is given in terms of plant and grid reliability and reserve margin. Data taken from a real power plant operation is used for this study. Obtained results are compared to show the improvement in grid reliability.
