Hitachi supplies voltage control system to WPD’s smart grid

Hitachi Europe, Smart Grid Venture has concluded an agreement with Western Power Distribution (WPD) for the supply of a Dynamic Voltage Control System for a smart-grid demonstration project under the UK’s Low Carbon Networks (LCN) fund tier one, established by Ofgem, the UK Energy Regulator.

The three-year project, which will begin this summer, aims to utilise Hitachi’s electronics and control systems to reduce voltage fluctuations on distribution lines where renewable energy is being connected.

In the first stage of the project, a single D-Statcom, which utilises IGBT technology to provide continuous reactive power to the network, compensating for voltage rise and flicker caused by the intermittency inherent in renewable energy generation, will be tested on an 11kV distribution line.

The second phase will involve a further three D-Statcom units controlled by Hitachi’s Voltage and Reactive Power Control System (D-VQC).
