摘要

The present invention relates to an apparatus and method for power sensitivity-based virtual multi-slack droop control in which a plurality of generators operate together as a slack generator in a power system with a high input amount of renewable energy to improve system stability. Synchronization data collection unit for collecting synchronization data; Multi-slack current calculation unit for calculating multi-slack current when operating point fluctuation is large, and power sensitivity calculation unit for calculating power sensitivity between load and generator; Power between load and generator A virtual multi-slack droop control unit that provides an optimal droop coefficient based on sensitivity in real time to enable power distribution between all generators, and controls the operation as a virtual multi-slack that indirectly controls the magnitude and phase angle of the bus voltage; It includes.
