The invention discloses a large-scale concurrent user access processing method orienting the intelligent electricity use field and a device thereof. The large-scale concurrent user access processing method orienting the intelligent electricity use field can be applied to an intelligent electricity use interactive support platform so that the platform is ensured to meet the access requirements of large-scale different levels of concurrent users, acquisition of request responses is facilitated for the users, and user access request response performance is enhanced. The large-scale concurrent user access processing method orienting the intelligent electricity use field comprises the following steps that A. after electricity users submit user requests, access adaption is performed by an access server according to access modes; B. user state maintenance is performed by adopting a similar Session mode; C. the user requests with attachment of Session identification enter an allocation server request waiting queue; D. user request allocation is performed according to the allocation strategy; and E. in an application server, user state information is updated after performing the user requests via combination of the user state information, Session is updated according to the state information, and then the request responses with Session identification are returned the corresponding users.
