The areas of the United Kingdom that are best suited to renewable energy generation tend to be away from population centres. Here, electricity networks increasingly find themselves having to limit renewable energy ambitions; often there is no simple solution. Given the long life of many network assets, change is either slow or expensive. The wholly community-owned Isle of Gigha in Scotland today finds its renewable energy ambitions limited in this manner. This case study sets out the rationale for an Energy Storage solution for this community that would enable increased renewable energy capacity, yield and value; with the potential to explore many of the other benefits cases attributable to Energy Storage at the weak edge of the electricity network. In March 2013 this project was awarded Feasibility Stage funding under the Department for Energy and Climate Change's Energy Storage Demonstration Programme[1]. Source

Great-Britain's unique Radio Teleswitch System (RTS) was developed in the 1970s, deployed en-masse by the Electricity Industry during the 80s and 90s. Today it controls electric storage and water-heating in homes numbering in the low millions. The need for its development mirrors the conditions of the near future, where much generating plant capacity will close and there will be a great expansion of electric heating in the form of heat-pumps. The system allowed this expansion to occur while limiting its economic impact on generation, transmission and distribution networks. This is as relevant today as it was in the past and provides functionality that the Smart Metering System (SMS) must duplicate, or else trigger network investments and higher costs for consumers.

The article presents development and implementation of an integrated asset risk prioritisation (ARP) tool on UK power networks. Asset Risk and Prioritisation (ARP) builds upon existing methodology of Condition Based Risk Management (CBRM) and shift of strategy from pure replacement to include refurbishment / asset life extension and more focus on TOTEX.

Real-time thermal management of electrical machines relies on sufficiently accurate indicators of internal temperature. One indicator of temperature in a permanent-magnet synchronous motor is the stator winding resistance. This study applies two current injection techniques to a commercially produced permanent-magnet servomotor, which are applicable under load and cause minimal disturbance to the shaft torque. The current injection techniques applied here enable the temporary boosting of resistive voltage and consequent application to low-resistance, high-voltage machines. The effectiveness of the approach is demonstrated by tracking the change in winding temperature during a 2 h load cycle. © 2012 The Institution of Engineering and Technology. Source
