LCNF Tier 1 project • As DG (Distributed Generation) becomes more common, the
growing number of renewable connections to distribution lines is
expected to cause voltage fluctuations (specifically high or low
voltage) due to the variable power output of the DG. In turn this
can affect the efficiency and capacity of the distribution network.

can affect the efficiency and capacity of the distribution network.
• Determine the effectiveness of D-STATCOM as a dynamic voltage
control system in rural 11kV networks to address voltage fluctuation.
• Optimise control by using a D-VQC (Voltage and Reactive Power
Control System) to network multiple D-STATCOMs.

control system in rural 11kV networks to address voltage fluctuation.
• Optimise control by using a D-VQC (Voltage and Reactive Power
Control System) to network multiple D-STATCOMs.
Goals
• 2 Strand project, initially 1 D-STATCOM as proof of concept, then 3
additional units as well as a D-VQC server.

Scope
• Improvement of power quality and mitigation of voltage spikes
issues, thereby increasing network stability, efficiency and load
capacity in distribution networks.
• Learning from project will be beneficial for informing DNOs business
case for alternative responses to network rebuild.

Background
UK Smart Grid Case Study – LCNF project with WPD
© Hitachi Europe Ltd. 2013. All rights reserved. 16
ETI Smart Systems & Heat Programme Overview
Launched in April 2012, the focus of the programme is the design, development
and demonstration of a first-of-a-kind energy system aligned with the needs of
UK consumers in the domestic and small commercial sectors with a particular
focus on heat delivery. Hitachi was announced as Programme Associate.
There are four key themes:
 Understanding real mass-market consumer behaviour in order to design and
communicate effective service products
 Providing energy services and integrated products to consumers in domestic
and commercial buildings (primarily domestic & retrofit)
 Space and water heating – but including other energy service needs in or
connected to buildings
 Understanding the evolution of the whole energy system out to 2050,
including building retrofits and energy distribution choices

Hitachi was announced as Programme Associate. There are four key themes:  Understanding real mass-market consumer behaviour in order to design and communicate effective service products  Providing energy services and integrated products to consumers in domestic and commercial buildings (primarily domestic & retrofit)  Space and water heating – but including other energy service needs in or connected to buildings  Understanding the evolution of the whole energy system out to 2050, including building retrofits and energy distribution choices
