The UK’s electricity transmission and distribution systems have little spare capacity to accommodate the widespread changes in volume and location of power flows arising from planned changes in generation type and characteristics, and from major changes in demand patterns. Gaining consents for the construction of new overhead lines is extremely time-consuming and costly. Without action, this will increasingly constrain the necessary changes in generation and demand.
The ‘Network Capacity’ project has assessed the feasibility of using new technologies now emerging in the marketplace or in development, including multi-terminal HVDC systems, in novel ways in order to provide increased Transmission & Distribution system capacity and improved management of network power flows, in order to facilitate increased renewable energy installation levels in the UK.
This document reports the results of an initial literature review addressing the state of the art of power electronic (component) devices and of system technologies based on them. It also includes a brief assessment of other relevant technologies (such as special protection systems and phase shifting transformers).The report introduces each of the technologies and relates the claimed benefits to the actual state of the art of each, and it identifies initial gaps and opportunities which form the basis of further work throughout the project.
The actual review begins on page 9 and is entitled “Review on Flexible AC Transmission Devices and High-Voltage DC Transmission Systems”
