Why is distributed control necessary in automation of energy distribution systems? How would you distribute the automation logic across many controllers?
I don't think it ist necessary to use a distributed control system - however in my opinion it is beneficial.
Distributed energy systems will have a lot of controllable devices in future. To realize a central control system a lot of effort is necessary for communication and data handling. In the end of the day, central control algorithms have to handle an increasing number of devices. So you have to ensure, that the whole system will not collapse by adding one additional device.
A distributed system can make use of cascading control systems: the base element may be "aggregators" which are able to act as one virtual single device in the distributed system - but effective it controls itself several devices. This approach of distributed control makes the system very flexible and stable.
Thats a nice answer,
Kindly Tobas can you also answer this question :
What kind of Challenges we have for applying “controller in the loop” simulation in distributed automation of energy distribution systems?
An intuitively described example of decentralized control related to electrical power distribution is given in
