In terms of the distribution system with distributed generators (DGs) especially considering the operation of micro-grids (MGs) composed of DGs and loads, an AER (Agent-Environment-Rules) Constraint Satisfaction Problem (CSP) based model to solve the serve restoration problem in the event of a large-scale blackout in a power distribution network with DGs is proposed. All agents live in a lattice-like environment using multi-agent system, and they can not only sense their local environment but also move in it. The operation method of DGs in the process of service restoration for large area blackout of distribution system with DGs is researched for making use of the capacity of DGs sufficiently and reducing the blackout area. The asynchronous backtracking algorithm is used to solve the AER model based on CSP, the values of the agents can be exchanged, and they also can be updated by the influence between the agents and the environment. Finally, the example results indicate the feasibility of the proposed method.
