A novel architecture for power networks with distributed generation - concept outline

Providing a secure power network is already a complex task but as network complexity grows with each new distributed generation connection so the problem of assurance for the next source connection becomes more and more protracted. A fundamental change to the network architecture may be necessary and an architecture based on cells containing both generation and loads has been proposed by some researchers. This paper proposes a novel power cell interface, replacing the conventional power transformer with an “active transformer” in order to provide a controllable, flexible and robust connection that will facilitate greater network management and business opportunities and new power flow control features
