ABB and EDF Energy Networks join hands

Power and automation technology group ABB and EDF Energy Networks are to work on a collaborative research, development and demonstration project in the UK to install an SVC Light with dynamic energy storage in a grid with a high penetration of wind power.

The installation will yield dynamic voltage control in an 11 kV distribution system and at the same time enable dynamic storage of surplus energy from wind farms, which can be utilised to level out peaks in grid loading.

According to EDF Energy Networks, this project will allow more renewable generation connections to existing electricity networks, and it will also demonstrate the value of energy storage. Using this strategy, the power harnessed from the wind can be put to more efficient use than would otherwise be possible.

The SVC Light with dynamic energy storage based on high-tech lithium-ion (Li-ion) batteries will be constructed in Hemsby, Norfolk, and connected to the distribution network between Ormesby and Martham in Norfolk, England. It will be in operation by the end of 2009.

The installation will improve the usability of power from wind farms and avoid the destabilising effect it can have on the grid.

The project is being financially supported through industry regulator Ofgem's Innovation Funding Incentive scheme.

SVC Light is part of ABB's FACTS portfolio. The term FACTS (Flexible AC Transmission Systems) covers a number of technologies that enhance the security, capacity and flexibility of power transmission and distribution systems, as well as enhance productivity and power quality in industry. SVC Light is a unique power semiconductor technology based on power transistors (IGBT).
