Abstract:In the event of a large-scale blackout in a distribution network, a service restoration plan must be devised quickly. To remedy such a situation, a restoration method based on the multi-agent genetic algorithm is proposed for the distribution networks with distributed generators (DGs). All agents in this algorithm which represent the restoration methods live in a lattice like environment, with each agent fixed on a lattice-point. In order to increase object function values, they compete with their neighbors, and they can also use knowledge. For the non-feasible solutions generated in the process of the algorithm, the method of the improved loop decomposition is proposed to eliminate the closed loops and islands. The operation method of DGs is 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 enhancing the power distribution reliability. Finally, the example results indicate the feasibility of the proposed method.
