Black Start of Multiple Mobile Emergency Energy Storage Vehicles without Communication

The extreme weather and natural disasters can cause outage of power grid while employing mobile emergency energy storage vehicle (MEESV) could be a potential solution, especially for critical loads in disaster relief. In such situation, the speed to build up the MEESVs system is a key point, which requires starting the emergency power networks in a simplest way. That means fewer knowledge of loads and avoiding interaction of communication are expected during starting up the MEESVs system. For these reasons, black start for the MEESVs, with no communication, is core technique for building up a stable emergency power supply system. In this paper, a communicationless serial black start control strategy is introduced, which is composed of pre-synchronization and current-limiting strategy. The proposed strategy can black start MEESVs without communication, so that to establish a stable power supply system quickly and reliably. Simulation and experimental results verify the effectiveness and feasibility of the proposed control strategy.
