Rapid restoration after fault of urban power grid is important. In this paper a self-healing restoration strategy integrated multiple objectives is researched. N+1 restoration architecture based on multi-agent technology is built to implement the self-healing restoration strategy. N substation agents are in charge of restoration task inside substations, and a network agent is responsible for the corporation of tie lines between substations. Optimized objectives of restoration are divided into several levels using delaminating sequence method. Optimized load shedding strategy when restoration strategy is not satisfying constraint conditions is also established. Transformer fault and line fault are simulated respectively. The results confirm the validity of the proposed restoration strategy.
