With the development of smart grid

it is very important to acknowledge and control the participation degree of smart power users

resulting from its contribution to the efficiency and stability of the grid.In this paper

an evaluation model of the participation degree of smart power users based on evolutionary game theory is proposed.Firstly

the users’revenues are selected as the game elements and the whole benefit model of the users is constructed

including electricity price profit and the users’satisfaction profit constructed by quantifying their electricity using experience.Secondly

the users’ choices are taken as the strategic spaces and the user groups are classified

in order to build up the evolutionary game model among different classifications of users.After that

the replication dynamic equations of the participation degree are established.Finally

two simulation cases were performed to validate the feasibility and effectiveness of the theory and model.
