An ICT Framework for Supplementary Electrical Heating for Decarbonisation of Domestic Heating

Lead Research Organisation: Queen's University Belfast
Department Name: Sch of Electronics, Elec Eng & Comp Sci

Abstract

This research concerns the use of 'Supplementary Electric Heating' as a means to reduce carbon dioxide emissions caused by the consumption of fossil fuels for domestic heating. This will be achieved by using advanced storage heating appliances, for space heating and water heating, that will consume electricity when there is an abundance of low carbon generation such as wind power. This augments the conventional central heating system in the household, and reduces the amount of fossil fuels (oil and gas) consumed.

To achieve widespread uptake of supplementary electric heating it is necessary to be mindful electricity grid operation. The supplementary electric heaters must respect capacity constraints on the distribution networks they are installed on, and not adversely affect power quality. Additionally, there are challenges operating electricity grids with high capacities of non-synchronous renewable generation, specifically grid stability and inertia. By equipping the supplementary electric heaters with advanced monitoring equipment, it is possible to utilise a large population of these appliances to assist grid stability and simulate system inertia.

In order to achieve this level of control, an advanced communications network is required. Electrical utilities have traditionally had little motivation to have widespread, real-time communications with customers. Thus, the main thrust of this project is concerned with identifying the information communication technology needs of the supplementary electric heating control systems under both normal operation and in times when they must respond to system faults, and constructing a framework for the successful operation of the whole system.

The ICT framework that will be developed in this work will consider the unique challenges of Machine-to-Machine communication in the utility sector, where cyber-security threats remain a persistent concern. The framework will form the basis for future technologies in the active network management, or 'Smart Grid', sector.

Planned Impact

The following beneficiaries may directly or indirectly gain from the proposed research. The beneficiaries include the worldwide electrical power research community, especially those working in active network management; the formal project partners outlined in the Case for Support; manufacturers of intelligent appliances, including manufacturers of electrical heating equipment (for example, Glen Dimplex); electrical utilities and renewable energy producers; the environment; the UK as a whole in meeting climate change targets and gaining a competitive edge in this technology.

The definition of a reliable and secure ICT framework for intelligent household appliances will create a trickle up effect into other sectors of industry, accelerating technologies which support renewable electricity generation and reduce carbon emissions to be rapidly designed, tested and deployed. The lack of a defined ICT platform is a limiting factor in the development of Smart Grids. Manufacturers of various appliances, either domestic scale or commercial scale, will benefit from a reference platform allowing interoperability of equipment. Utilities will benefit from a common platform for issuing commands and taking measurements from intelligent appliances.

Impact Plan
To ensure that the impact of this research is maximised for the beneficiaries, the PI will:

1) Make full use of conference presentations and attendances (e.g. IEEE PES GM) to publicise the outcomes of the research,

2) Publish in leading journals of the IEEE / IET in accordance with EPSRC open access policy,

3) Make visits to the collaborator's institutions and give talks related to the research, making use of QUB business engagement professionals,

4) Use websites, social media and other means of dissemination of the research findings,

5) Maintain involvement in professional working groups where the impact of the research can be utilised.

Description Preliminary investigation suggested that transitioning to electrical heating would realise an immediate reduction in greenhouse gas emissions compared to the use of oil and gas in domestic properties. Rigorous investigation of the source data for greenhouse gas emissions by generation type yields a more complex story, suggesting that electrification alone yields a marginal improvement. For significant improvement, intelligent control is necessary.

Consequently, a telecoms framework has been designed which allows for rapid, full control of domestic heating appliances such that they can be optimised to yield environmental benefit, technical benefit to the system operator, and potential for economic benefit to the owner subject to the creation of market mechanisms.

A demonstrator system has been created at the university, and further projects with existing and new industry partners are carrying the project to the next phase.
Exploitation Route A demonstrator system has been created at the university, and further projects with existing and new industry partners are carrying the project to the next phase.

Description Informal meetings with the Northern Ireland Housing Executive have occurred to describe the research on Supplementary Heating. This has led to advising on the potential for Supplementary Heating to be integrated into the design of new social housing with a view to lowering bills for the residents and decarbonising electricity generation as a whole. This work continues into 2017. Additionally, the new CASE grant, DINOSAURS, will see discussions with electrical utility TSO/DNO, equipment vendors and service aggregators to tailor the ICT framework to produce a feasible practical solution to demand response. In 2021, preliminary research has commenced on new low cost sensor technologies. Funding will be sought in the near future.

PI Contribution My research team and I have developed a scalable, reliable and secure telecommunications design framework applicable to the products producted by Glen Dimplex, namely their range of space and water heating electrical appliances. The framework has been designed with security in mind from the outset and utilises a number of proven open sources technologies. The innovation added has been the application of these technologies to extremely low cost embedded system devices, making their practical application a possibility. The technology is applicable to all distributed energy resources (DERs) and can be tailored to suit other appliance or vendor requirements as necessary.
Collaborator Contribution Geln Dimplex are facilitating the adaptation of their Quantum storage heater project to an open source telecoms system developed under the Supplementary Heating Project. Glen Dimplex have provisioned engineer time to liaise with the funded Research Assistant to develop a protocol converter to exchange data between their closed source interface and the new open source interface which is under development. As of the end of the project, a demonstrator system has been created, shown to be operational, and the is the subject of publication at an international conference.

Description Statnett SF (Supplementary Heating) 
Organisation Statnett
Country Norway 
Sector Public 
PI Contribution My research team and I have presented our open source telecoms framework for distributed energy resources (DERs) to Statnett ST, the Norwegian electricity Transmission System Operator (TSO), throughout its development. Norway is a heavy user of electrical heating appliances, and Statnett have a track record in the use of intelligent control systems for operating their grid. Feedback from Statnett on the design of our telecoms framework was extremely useful, providing a TSO's perspective. Consequently, this informed the design of how appliances should be "clustered" in the logical hierarchy of the telecoms system, affording the TSO fine/subtle control over bulk numbers of appliances.
Collaborator Contribution Statnett SF have given advice on the heating loads seen on the Norwegian power system and how these are accommodated and controlled in line with system dispatch. Details have been provided of incumbent technologies, and the advantages and limitations of current designs. This proved crucial to understanding the TSO's perspective for the control of intelligent heating appliances, and informed the design of the telecoms framework.
Impact Publications have been presented at major conferences nationally and internationally (UPEC, IEEE PES GM). A notable outcome of this work is that Statnett have seen the benefit of the telecoms framework designed for DERs being applied to the monitoring of Phasor Measurement Unit equipment. A new project in this area is in developmental stages.
