摘要：
The power supply restoration in fault-free areas can effectively improve the system self-healing ability after power system fault. For offshore multi-platform interconnected power systems with emergency generators and energy storage device, this paper proposes a power supply restoration strategy for island power grids after fault. First, four kinds of indicators is proposed in the optimization model for power supply restoration, i.e., the fault recover effect, the time cost of fault recovery, the influence on power flow in fault-free area, and the number of the emergency generators. Moreover, the optimization model is given with the constraints of power flow, network safety and topology. Then, the genetic algorithm is used in the power supply restoration strategy to adjust the switching state of the power system, to recover the power supply in the fault-free area. Finally, the effectiveness of the proposed power supply restoration strategy is validated through the extensive simulation experiments on IEEE 53-bus distribution system and the offshore multi-platform interconnected power system. In addition, the self-healing control ability of the offshore multi-platform interconnected power system with the energy storage device is evaluated. © 2021 Automation of Electric Power Systems Press.
