Innovation Strategy Close Out Report - Innovative LV Auto-Reclosing on Intermittent Faults to Reduce Customer Outages

As extreme weather events and cybersecurity threats become more frequent, and our economy electrifies, ESB Networks will need to build network resilience to mitigate disruption, ensure the security of supply.

Intermittent Faults on Low Voltage (LV) underground networks cause temporary loss of supply to customers. Due to the nature of these intermittent faults they have proved difficult to locate. ESB Networks planned on using the REZAP Vacuum Circuit breaker and BIDOYNG smart fuse, from Kelvatek, to improve LV performance as part of the Smart Grid MV/LV Control Operation trial. This aimed to deliver improved continuity and customer satisfaction.

Innovation Strategy Close Out Report - Special K – Improved Continuity for 20kV earth faults by reducing the range of SEF operation

As extreme weather events and cybersecurity threats become more frequent, and our economy electrifies, ESB Networks will need to build network resilience to mitigate disruption, ensure the security of supply.

Sensitive Earth Faults (SEF) are difficult to detect as they have very low fault current values. During SEF operation, the protection device does not attempt to automatically reclose the circuit breaker to test if the fault conditions are still present. Customers remain off supply until the site is visited by ESB Networks staff. The project’s aim was to trial innovative approaches to SEF to improve the continuity of electrical supply to customers.

Innovation Strategy Close Out Report – Data Analytics for Revenue Protection Fraud Detection

As extreme weather events and cybersecurity threats become more frequent, and our economy electrifies, ESB Networks will need to build network resilience to mitigate disruption, ensure the security of supply.

With the use of data analytics ESB Networks pursued a new avenue in identifying metering anomalies and developing a tool that can identify suspicious readings related to meter interference. The project developed an algorithm that can rank a pool of different meter readings based on statistical probability. ESB Networks revised the initial algorithm to a more complex version that is fine-tuned over time as more data is collected and analysed. The expected roll out of smart meters should lead to an increase in data volume and allow further fine tuning of the algorithm with AI.

Innovation Strategy Close Out Report - Staff Digitisation Project – Lone Working Safety Device

Delivering a future-ready network service and ensuring operational excellence requires a deep understanding of where, how, when customers use the network, why faults occur, and having the ability to deploy solutions quickly. Central to these efforts is the empowering employees with the technology necessary to gather, manage and analyse network data.

The safety of over 1,950 Network Technicians and over 1,000 other field staff who travel alone is paramount. In order to reduce the potential vulnerability of our staff working alone, ESB Networks introduced a safety device to provide extra reassurance. This project tested and assessed the suitability and associated integration into our digital system of the V.ALERT lone working device to improve lone working safety in case of an emergency.

Innovation Strategy Close Out Report - Real Value – Balancing Heat and Electricity Demand

Traditionally, large fossil fuel based generation provided flexibility on our systems. New flexibility technologies such as energy storage, vehicle to grid (V2G), web based domestic control systems, Smart Meters, advanced information sensing, advanced data analytics and new supplier business models are now emerging to take the place plant of large fossil fuel generators and decarbonize flexibility.
The aim of the Flexibility on Our Networks roadmap is to understand the impacts and the possibilities provided by the use of flexibility in the overall electrical energy system and also develop systems and processes that cost effectively enable the provision of flexibility from within the distribution network.

Real Value was a H2020 project to investigate the impact of controllable electric heating to provide a more flexible network and a solution to Demand-Side Management (DSM) at Low Voltage (LV) level. This allowed energy users of all kinds to act as “virtual power plants”. The project was completed in collaboration with Glen Dimplex, EirGrid, Intel, SSE, UCD and Oxford University and included physical demonstrations in Ireland, Germany and Latvia where the Smart Electric Thermal Storage (SETS) units were installed into 1,250 homes.

Innovation Strategy Close Out Report - Planning Future LV Networks for Electrified Heat and Transport

As our customers choose technologies including air source heat pumps (ASHPs), storage heating, private electric vehicles (EVs), electric buses, freight and trains in ever higher numbers, greater demands will be placed on the network.
ESB Networks must innovate in network planning and operation, to meet these new demands, without compromising our customers’ comfort, security or quality of supply, and at an economic cost reflecting our customers’ needs and values.

Central to the electrification of heat and transport is to ensure the Low Voltage (LV) network can support and enable the increasing electrical demands from customers’ low carbon technologies. The project will deliver new and consistent design approaches for new and existing LV networks. This will support the economic integration of customers’ low carbon technologies and distribution energy resources such as electric vehicles, solar PV and heat pumps. This involved robust statistical analysis to derive new metrics, values and design tools for the LV network.
