4) whether electric power Collaborative Control unit, heating power Collaborative Control unit and natural gas Collaborative Control unit confirm each equipment respectively
In higher level's control model, the control parameter obtained by calculating is handed down to the equipment if equipment is in higher level's control model；
Collaborative Control unit only receives the operation information of equipment upload if equipment is in autonomous control pattern；
5) within the Δ T periods, electric power Collaborative Control unit, heating power Collaborative Control unit and natural gas Collaborative Control unit judges system
Whether system running status meets tolerance scope, and each equipment control parameter is recalculated if being unsatisfactory for；Meanwhile, electric power association
Same control unit, heating power Collaborative Control unit and natural gas Collaborative Control unit are respectively by communication control network, from being administered
The local control device of equipment obtains equipment job information, and real time coordination control is carried out to each equipment；
6) day level dispatch layer obtains system running state information from data interaction bus, and corrects the scheduling meter of future time period according to this
