摘要： A power system including a first and a second grid, each grid having power flow parameters. A breaker installed at a point of common coupling between the first and second grid. A first and a second sensor, each located on a side of the point of the common coupling for determining the power flow parameters of the first and second grid. A controller, iteratively controls a power source to supply a first amount of power, based on determining a frequency mismatch between the first and the second power grid, until a first predetermined condition is met. Then, determines if the first and second grid reach a second predetermined condition of phase mismatches and frequencies mismatches of the first and second grid, and if not, iteratively control the power source to supply a second amount of power until the second predetermined condition is met, then places breaker in closed position.
