Future network architecture — power network, protection, control and market requirements for 2020

As distribution networks have traditionally been passive networks facilitating power flows in one direction from the grid intake point to demand customers, the architecture of future networks incorporating high levels of distributed generation needs to address not only the requirements of the power network but also the necessary changes to meet the corresponding protection, control, market and regulatory requirements. The report described in the paper considered the network architectures for three scenarios to 2020 in Great Britain with increasing levels of distributed generation, particularly micro-generation connected at low voltage (LV).
