Description
Technical field
The present invention relates to network security and intelligent grid field, specifically a kind of demand response event method for managing security of based role and system.
Technical background
Intelligent grid relies on the electric energy switching network of messaging platforms and intelligent control platform as one, has informationization, automation, the feature such as interactive, and to realizing energy-saving and emission-reduction, electric power resource distributes rationally and play an important role.Demand response (Demand Response, being called for short DR) technology is one of core technology in intelligent grid, by taking effective incentive measure, power consumer is guided to optimize power mode, improve terminal power consumption efficiency, realize effective control of power system load, create good economic benefit and social benefit.In recent years, along with proposition and the development of automatic demand response concept, the new model of this demand response further enhancing the participation initiative of user, improves level of response.The carrier that DR event is transmitted as information between the Utilities Electric Co. in automatic demand response and power consumer, has very important status in the entire system.
DR event is due to the particularity of its status, once be attacked by lawless person and distort, or be forged issue, will bring grave danger to the normal use of the normal operation of Utilities Electric Co. and power consumer, these threats bring new challenge to national security and public safety.Meanwhile, because in electric power system, involved department, equipment, user etc. are of a great variety, validated user unauthorized operation, misoperation event happen occasionally.So in automatic demand response, how effectively to manage DR event and to carry out safe and reliable transmission to it, be one of problem demanding prompt solution in the automatic demand response safe practice of intelligent grid.
1) through finding existing literature search, Chinese Patent Application No. 201280040033.8, name is called " automation demand response system ".Receive the information from the demand response event of automation demand response server at automation demand response client place, system determines the multiple equipment wanting controlled building automation system during demand response event.System is the scheduling scheme that multiple equipment prepares the controlling behavior during demand response event.Control message is sent to building automation system by system, to perform the controlling behavior to multiple equipment according to the scheduling scheme for the controlling behavior of demand response event.
The scheme that this patent provides is in electricity consumption side according to DR event information, by this building automatic demand response system, carries out scheduling controlling to intrasystem equipment, with the power consumption of facility during automatically and efficiently reducing various DR event.But the program just carries out automated decision-making based on DR event information, if consider the safety problem of DR event information itself, also there is many tender spots, such as DR event such as is forged or distorts at the external factor.These external factor can cause automation demand response system to lose original effect.
2) Chinese Patent Application No. 201110349716.9, name is called " for changing power device and the power management apparatus of demand response control hierarchy ".The current power state information sent in real time is used by power device, controller by current electricity prices rank compared with the DR control hierarchy of expectation, and determine it is the use or the consideration economize on electricity aspect that increase power device, thus adjust the beginning rank of DR control adaptively.
The scheme that this patent provides is in electricity consumption side mount controller, and the DR information of Demand-side sends over by communication unit, determines whether respond this DR event by comparing DR control hierarchy.Such as, but the program can only carry out decision-making to the DR event of electricity consumption side, if consider the safety problem of supply side and communication unit, also there is tender spots, communication unit is by illegal attack etc.These factors can affect the normal operation of electricity consumption side demand response.
