Hitachi Europe Smart Cities Energy Group and Western Power Distribution
The need to preserve the environment through reducing CO2 emissions is recognised by governments worldwide. The UK has ambitious targets to reduce carbon dioxide emissions by 80% from 1990 levels by 2050. Part of the answer is to increase the use of renewable energy sources such as wind and solar power, however this causes challenges for the UK's electricity distribution networks. Hitachi Europe Smart Cities Energy Group is instrumental in helping Distribution Networks Operators (DNOs) meet these challenges.
Helping to provide a secure and stable supply of electricity
The UK's variable weather means that the power generated from renewable energy sources fluctuates constantly. Western Power Distribution, the UK's largest DNO, have recognised the challenge to be faced from increasing renewable energy sources connected to their network. They have partnered with Hitachi Europe Smart Cities Energy Group to find a solution to voltage variations.
Hitachi installs Europe's first D-STATCOM system for Western Power Distribution
The Hitachi voltage control system project addresses the challenge of fluctuating voltages caused by renewable energy sources connected to the distribution networks. The first D-STATCOM device was manufactured in Japan, and shipped to the UK, where it has been installed adjacent to a wind farm in South West England.
Reducing voltage fluctuations and increasing load capacity
Hitachi approached Western Power Distribution with a range of smart grid solutions, but it was the voltage control system utilising Hitachi's D-STATCOM that stood out as the preferred one. The Hitachi D-STATCOM is a static synchronous compensator designed for distribution networks that can source/sink reactive power, thereby controlling voltage on the network. The device comes in a much smaller footprint than traditional highly complex transmission level SVCs as well as combining high-speed operation, performance and flexible control. Initial simulations show that the Hitachi D-STATCOM can improve voltage levels in some instances greater than 60%.
About Western Power Distribution
Western Power Distribution is the electricity distribution network operator for the Midlands, South Wales and the South West. The company delivers electricity to more than 7.6 million customers over a 55,300 sq kms service area. The network consists of 216,000 kms of overhead lines and underground cables, and 184,000 substations.
