Periodic Reporting for period 2 - RealValue (Realising Value from Electricity Markets with Local Smart Electric Thermal Storage Technology)
Période du rapport: 2016-12-01 au 2018-05-31
Main objectives:
• Physical demonstrations, involving over 1000 participants, of a domestic load aggregation platform that will link the electricity and heating sectors in three member states (Latvia, Germany and Ireland)
• Refine existing ICT systems and procedures to interface distributed populations of local small-scale thermal storage devices (SETS)
• Combine the experiences derived from the contemporary physical demonstrations with future projections from the desktop modelling studies
• Carry out thorough market and regulatory policy investigations
• Carry out consumer research and behavioural studies
• Devise robust business models
• Disseminate the experiences, findings and conclusions of the project
The RealValue solution: Properties were equipped with Smart Electric Thermal Storage water and space heating devices, plus smart plugs, sensors, smart meters and gateways. A gateway, connected to the internet, links the heating appliances to an aggregation platform, which at cloud level provides the ability to interpret the flexibility of the devices. This information is transmitted to a cloud optimization engine which is integrated with the electricity grids in each country, allowing an understanding of the current and future wholesale prices, and other network constraints. An optimised charging schedule for each appliance is calculated and passed through the gateway to be activated, providing load balancing services. Through the backend, data can be extracted from individual appliances, and software and security updates can be pushed to the gateways. Participants have access to an app (available on phone, tablet and desktop) which provides remote control of the devices as well as insight into energy usage. In Ireland, SETS devices were installed in private homes and housing association properties as well as a range of non-domestic properties including a fire station, town hall, classrooms, office facilities and substations. In Germany, SETS devices were installed in over 100 homes. A ‘retrofit’ solution allowing smart control of traditional (i.e. non-smart) storage heating was installed in 25 properties. A further control group of homes with traditional storage heating received smart meters. In Latvia, SETS devices were installed in a range of domestic and non-domestic properties including substations, holiday accommodation, a shop and a beauty parlour & hairdresser.
A range of methods were used to build an overall picture of consumer interaction with SETS technology within RealValue including: surveys, interviews and focus groups (with demonstration participants as well as project delivery coordinators and ‘middle actors’ e.g. housing managers, local council representatives, installers, call centre staff etc.); observation; analysis of customer data (call logs, bills etc.) and telemetry data collected from the appliances. Alongside this, building and energy system modelling was carried out to assess the relative suitability of European countries for SETS devices and the new functionalities they offer. Additionally, business modelling and regulatory and market analysis activities assessed the market readiness for the RealValue solution and identified the most interesting business cases. The project’s main results and achievements have been disseminated widely throughout the project, culminating in the Final Event was held in Brussels in May 2018.
