Service restoration strategy of AC/DC hybrid distribution networks

This study proposes a service restoration strategy for an AC/DC hybrid distribution system. A mathematical model for voltage source converter with different control strategies in service restoration is developed. Power storage system scheduling strategy is also designed for restoring more power supply. A mixed‐integer second‐order cone programming is developed for network reconfiguration, and constraint express can make sure the distribution network operates in a radial manner. With the conditions of power balance in islands as the constraints, the islands are then divided. It adopts minimum loss in the object makes it not only stable but also economically acceptable. Simulation results show that the purposed strategy is feasible and effective to reduce lost load, distribution generation curtailments, and network loss.
