Abstract: With the gradual development of the energy internet and power system reform， as an important part of strong smart grid，smart electricity will face to the power user directly. So it is much more automated and intelligentized to smart electricity in the future because of the development of distributed generations. In this paper, considering with the user electricity charges, the response strategy of electricity market was discussed according to peak-valley time-of-use tariff. Firstly, smart electricity and response characteristics of resident load were studied. Secondly, in the light of price demand response, an optimization model for least cost of electricity was proposed. Lastly, combination of distributed power access, a demand response strategy based on incentive mechanism was proposed, and an active load demand response scheme for maximum absorption of distributed generations. It is proved that this scheme can improve the efficiency of new energy dissipation, save the electricity fee of the users. And it provides a theoretical basis for intelligent electricity use strategy in the future.
