Global Summit and Expo on Power & Energy Engineering Dubai, UAE February 18-20, 2019 Theme: The Digital Power Future is Now

Dudley Stewart (Chartered Power Engineer): – having directed Alternative Energy Development in the Energy-crisis in Bangladesh (mid-70’s), Dudley founded in Ireland the R&I Group in wind generator blade, governing and inverter systems. In the Mid-80’s he implemented senior energy design & development in Europe and in crisis-stricken situations in Africa. Returning in the late 80’s, he directed the hi-tech-enterprise accelerator Powerhouse and later directing the energy research compact, MEGA, Dudley has continued to drive significant and relentless R&I focused on the struggle in Europe for Climate Change Mitigation and Energy Independence. Ireland is at the cutting-edge with continued growth in hi-tech economy/population, at the wrong end of the long energy supply pipe-line.

The consequential user willingness to unite Energy Prosumers coupled with the Hi-tech Sector, has pushed Ireland into a position where radical changes in the Electricity System are within immediate reach. Ireland’s grid is relatively tiny but its reputation for sustained reliable power quality and grid-stability is second-to-none – sustaining this while racing through the Energy Transition cloud to reach the new Digital Energy ERA is the key focus of MEGA. MEGA’s fledgling MPOWER succeeded in securing the current formation of the Smart Energy Lab, the Tallaght Smart Grid Test Bed (South Dublin County Council) and the Limerick EU Lighthouse City.

Unlocking the vast quantities of latent Grid-Edge flexibility to support and refine distributed production, from diverse and severely intermittent sources (renewables & energy recovery), is the biggest on-going innovation to electricity markets. MPOWER, in Ireland, is the first dedicated Energy Community Utility having developed ‘disturbance-neutral energy communities’. Such communities respond autonomously, i.e. with minimal or no interaction with the DSO/DNO, to disturbances from production/Storage/Flexibility hosted by that community. These local, but otherwise virtual “cellular smart-grid” communities of flexible Consumers and Producers (Prosumers) create overlay ‘Community Grids’ (Regulated by Contract), with minimal disruption to DSOs.

Community Grids are operated by new market players such as: Community System Operators or CSO. They use cloud technology that implement dynamic, local markets, aggregated Regionally/Grid-wide, and integrated with advanced controls distributed to the Prosumers in the Community Grid. The Limerick EU-Lighthouse City, supported by the South Dublin Smart Grid Test Bed Technology, is rolling out neighbourhoods of such Smart Energy Cells bounded within Substation Areas by digitally-automated CSO-operated Community Grids. In these neighbourhood, smart energy, cells evolution towards the long-term Cellular Smart Grid System, the ultimate Digital Energy Architecture, is in easy stages.

Maturity Level 1: focuses on the Power Matching, in real-time (supported by the Community Grid Stabiliser – Hub with oneM2M Long Range Comms), of all new Renewable or Energy Recovery Generation by Local Consumption in real time based on Dynamic Energy (Auction) Values with surplus Energy taken up by batteries/flexible-devices being incentivized for speed of response to surplus and deficit situations. This forms the key building block of new Local Energy Markets which will become an invaluable resource for the DSO/DNO, relieving congestion and providing increasingly sophisticated (machine learning + ultraCap-driven dedicated power quality rectifiers).  Maturity Level 2 follows further investment within the Energy Community, in Flexibility Plant, into DSO-CSO integrated Smart Demand Response on an inter-cellular scale (i.e. Smart Cities and Towns) free of congestion issues. This prepares regulated Energy Communities for Maturity Level 3: automated Virtual Power Plant response by Dispatch and Ultra-Fast Frequency response and intelligent digital synthetic inertia.
