Voltage sags are one of the main problems in transmission and distribution grids with high penetration of distributed generation. This paper proposes a voltage support control scheme for grid-connected power sources under voltage sags. The control is based on the injection of reactive current with a variable ratio between positive and negative sequences. The controller determines, also, the amount of reactive power needed to restore the dropped voltage magnitudes to new reference values confined within the continuous operation limits required in grid codes. These reference values are chosen in order to guarantee low current injection when fulfilling the voltage support objective. Selected experimental results are reported in order to validate the effectiveness of the proposed control.

Proposed edge detection method based on bee colony algorithm. Utilization Characteristics colony algorithm for image boundary quick search, too To a group of local optima, and then were local minima to start the search, to find the edge of the image points of the object, all the bees to find the boundary point The union is the image edges. Simulation results show that the algorithm is feasible and effective.
