At Grid Edge, we want to change the way that people use energy by putting intelligent control into the hands of commercial energy consumers and creating new value on their side of the meter. Formed as a spin-out company from Aston University, Grid Edge is an early-stage technology start-up company that is developing cloud-based Artificial Intelligence (AI) software that empowers commercial energy consumers to intelligently control and optimise their building energy loads. Our innovative AI software deploys predictive machine-learning algorithms and advanced data analytics to reduce energy costs, cut carbon emissions and unlock the revenue-generating potential of flexible energy assets. By creating this new form of intelligent flexibility within our customer’s building energy loads, Grid Edge is also able to create a range of new value propositions for energy suppliers, traders and settlement market interests in the £1billion+ UK electricity balancing market.

To support the decarbonisation of our energy system and to enable increased renewables-penetration into our energy mix, the UK's energy system requires new forms of flexibility: Ofgem forecasts requirements of 150 GW of system flexibility, with 15GW from demand-side actors. Accordingly, the UK Government is introducing regulatory reforms ('wider access' reform such as those enabled by ELEXON P375 regulation changes, Virtual Lead Parties, and 'Behind the Boundary' settlement) designed to facilitate the development of new forms of demand-side flexibility. Grid Edge believes that dispatchable assets found in commercial buildings are one of these required new sources of flexibility, and that they are ideally placed to benefit from the forthcoming changes in energy market regulation. However, these building assets are currently being underutilised as sources of flexibility, due to two related factors: Building operators prioritising occupant comfort over flexible load management goals (and perception that this may be jeopardised by dynamic load management), A perception that conventional demand-response mechanisms are too rigid or ill-designed to accommodate the variable within-day loads and conditions of commercial buildings. We believe that the critical enabling innovation required to overcome these barriers is the application of predictive data that can connect and contextualise the requirements of both the building operator and the energy system simultaneously: i.e. enabling building operators to predict, optimise, and control the impact on comfort of dynamically adjusting their energy demand in response to new flexibility requirements and opportunities. As such, this project will support the creation of a new predictive load optimisation technology that aims to empower commercial building operators to dynamically predict, optimise, and flexibly control their energy profile in line with emerging energy system flexibility requirements. The project will pay particular attention to potential for building energy assets to exploit the new forms of flexibility opportunities that are being created by Ofgem's wider access reforms, such as the creation of Virtual Lead Party mechanisms and emerging agile tariff structures enabled by 'Behind the Boundary' settlement. In addition, the project will also explore the critical enabling role that Facilities Management providers play as gatekeepers to building and energy data, and as guardians of energy and environmental management in the built environment. As our understanding of emerging flexibility opportunities and markets has advanced, the project has taken responding to the carbon intensity of the grid as its most accessible opportunity, providing the ability for any building to reduce its carbon emissions by scheduling consumption to occur during periods of low carbon intensity and avoiding consumption during periods of high carbon intensity. By combining this with our predictive models on building assets and their effects, we can provide building operators recommendations on when and how to shift their loads for minimal effect on the occupants and maximum reduction in carbon. It is expected that since energy costs tend to follow carbon intensity, benefits will be amplified by new market opportunities, providing additional financial incentives for improving consumption profiles in this way.

Our electricity system is changing towards having a greater proportion of non-flexible generation from either intermittent renewable or nuclear sources and as behaviour in our society change around modern work practices and changing patterns of consumption behaviour. As this transition progresses there is an opportunity for the controlling influence in the energy system to move away from the small group of large powerful incumbent organisations towards the majority of agents within the system, the millions of system users. This project enables those customers to redefine themselves as participants within the energy system. The developments in this project allow building owners to use the dispatchable electrical loads in their buildings to become a dynamic and flexible energy sink, store and buffer asset, continuously pairing off against intermittent renewable generation and providing the system stability needed for the whole system to operate reliably. By unlocking these dispatchable load resources this project opens the path for a 100% zero carbon future electricity system.

Microgrids are small-scale power subsystems that include distributed energy generations, energy storages, and local loads. Microgrid technology will allow the power grid to accept more clean distributed renewable generations. It has great potential to increase the energy efficiency and security, and contribute to one of the UK industrial strategy priority areas "Cheap and Clean Energy". Compared to alternating current (AC) power systems, direct current (DC) power systems has the advantages of simpler control, higher reliability and efficiency, and has gained a continually increasing interest in the last several years. This Fellowship will work together with UK industries to address the challenge of achieving plug-and-play low voltage DC microgrids, provide ease of use for the technology, and explore new business cases in both building and industrial applications. The plug-and-play concept means the DC microgrid stable operation should not be affected by the connection/disconnection of power converters to the system, and the system control algorithm can be updated after a power converter is connected or disconnected. Also, users should have a group of compatible DC microgrid devices to choose from different manufacturers. In this Fellowship, the fundamental mechanism of DC microgrid stability will be studied, and a novel passive interface filter based solution will be implemented, so that off-the-shelf power converters can be used without changing its design. Design guidelines and software tool will be provided for DC microgrid industrial engineers. A novel simultaneous power and information transfer technology will be developed for DC microgrid control, so that high performance plug-and-play control can be implemented without external communication links. Together with industrial project partners, a reconfigurable DC microgrid research and demonstration platform will be developed to evaluate and demonstrate the developed technology, and support industry to explore potential new business cases in building and industrial applications.
