This paper proposes an automatic demand response strategy based on event-driven mechanism, considering great challenges brought by the diversity and richness of residential loads and random electricity consumption behaviors to residential multi-microgrid system. The operation statuses of residential microgrids are divided into different events by using event-driven mechanism. The residential load is guided to fulfil consumption optimization considering price incentive and schedulable potential with the event-driven signal, so as to achieve automatic demand response. On this basis, the concept of energy level is introduced to the energy sharing model. By calculating the energy levels of each sub-microgrid in multi-microgrid system, the interactive power among microgrids is determined. The decoupling between inter-network and intra-network can decrease the complexity of energy sharing model. The numerical simulation results of a residential multi-microgrid system show that the proposed algorithm can effectively reduce operation cost of residential multi-microgrid system and improve optimization efficiency.
