Total carbon emissions amount minimum etc..The number of devices for needing to control in the following power distribution network CPS can be real significantly more than current distribution system
Calculation amount needed for now concentrating optimum control can shy huge very much, it is therefore necessary to which centralized control is combined solution with decentralised control
Certainly problem.Power distribution network CPS carries out Partial controll to physical equipment by various embedded control systems, is controlled by on-line coordination
Coordinate whole system with necessary directly control.How to design more flexible and effective control system with realize global optimization with
The optimal coordination of Partial controll is power distribution network CPS primary technical problem to be solved.
(2) large-scale distributed calculating.Such as cloud computing of large-scale distributed computing technique is to solve power distribution network CPS calculating to ask
The effective way of topic.Existing computing resource in system can be effectively integrated using cloud computing technology, is appointed for various analytical calculations
Business provides powerful calculating and storage capacity and supports.Cloud computing can support various Heterogeneous Computing resources, the super meter with centralization

The mode that distributed computing model based on cloud computing is relatively suitble to power distribution network CPS centralized control to combine with decentralised control.
(3) CPS communication protocol.CPS is a kind of new network system, it is therefore desirable to construct special network communication association for it
View.There are a large amount of technical problems to need further to be studied for the communication protocol of CPS.As how guaranteed all computing systems in network
It is synchronous, how to handle the entirely different physical equipment of various properties, how for physical equipment status data definition format, etc.
Deng.
(4) dynamic network and delay/interruption tolerant network.A large amount of wireless devices may be accessed in power distribution network CPS, it is such as electronic
The sensing and control system and other wireless sensor devices of automobile, this just constitutes an exemplary dynamic network.In addition, by
In distribution system to reliability and line computation analysis rate request it is very high, this requires communication network must have it is very strong

The problem of research.It is significant to note that safety of this problem necessary not only for concern physical system, it is also desirable to pay close attention to
The safety issue of information system.In research safety problem, stochastic system failure should be considered, also to consider artificially to attack
And destruction.Artificial attack includes physical attacks and virtual attack again.Information system security and physical system be not safely it is isolated,
It may also lead to the extensive failure of physical system to the attack of information system.
(4) reliability.Fail-safe analysis is the basis for carrying out systems organization, design, scheduling.Under power distribution network CPS environment
