Distribution service restoration with DGs based on multi-agent immune algorithm

In terms of the distribution system with distributed generators especially considering the operation of microgrid (MG) composed of distributed generation (DG) and loads, the model based on multi-agent immune algorithm is proposed to solve the service restoration problem in the event of a large-scale blackout in a power distribution network with DGs. The antibodies are coded according to the method of `random tree´ to avoid lots of unfeasible solutions. High-Frequency method is introduced as the mutation operation of antibodies. In the process of searching for the best solution, antigens were changed dynamically in order to get the best solution as quickly as possible. At last, the calculation example manifests the efficiency and quickness of the multi-agent immune algorithm.
