Abstract：On the premise of ensuring the reliable service restoration of the active distribution network and in order to realize the interest balance between the power supply side and the user side, a game strategy for active distribution network service restoration using multiagent systems (MAS) is proposed. In order to consider the influence of the power grid and power consumers to service restoration, an MAS composed of the power grid agent, the user general agent and the coordination agent is designed, and an information transmission model of MAS is built. Then, the interest functions of the power supply side and the user side in the recovery processes, the space of recovery strategies, and a cooperative game recovery model taking the power grid agent and the user general agent as participants are established. The power grid agent and the user general agent are performed by distributed parallel computing with improved ant colony algorithm and the statistical method respectively. The coordination agent takes the common interest function of both sides as the optimization objective, and the recovery scheme satisfying the Nash equilibrium is obtained by iteration algorithm. This paper takes IEEE69 node model as an example to solve single fault and cascading failures, and the effectiveness of the proposed strategy is verified.
