The key technology research on transient stability control of micro-grid

This paper made a further research on the key technology of micro-grid transient stability control, and putted forward the distributed generations union scheduling Algorithm, that take the storage inverter control model as the core, Based on ultra-short-term forecasting of distributed generations output by means of BP neural network. It guaranteed micro-grid bus voltage to achieve “zero intermittent” during micro-grid transfered from grid-connected to island mode when city grid appearance fault. It ensures micro-grid running stably and maintained transient stability during disturbances in the island mode. It ensures the safe, steady and optimal economy operation of micro-grid.
