  1. Benefits of Advanced Smart Metering for Demand Response based Control in UK Distribution Networks • Chin Kim Gan, Marko Aunedi, Valdimir Stanojevic, Strbac Goran, (Imperial College) • Dave Openshaw (UK Power Networks) Goran Strbac – UK – Session 4 – 0710

  2. Background • UK response to climate change challenge • Significant increase in contribution from renewables (2020) • Decarbonisation of electricity system by 2030 • Increasing electricity demand through electrification of heat and transport demand • Energy efficiency, demand response, smart metering rollout • Objectives and scope • Quantify the impact of the integration of transport and heat sectors on the UK electricity distribution network investment • Evaluate required investment under BaU and Smart Management scenarios • Inform UK debate on smart metering functionality

  3. Penetration scenarios for EVs and HPs

  4. National level analysis – Electrifying heat and transport sectors

  5. Local level analysis: Impact of commuting driving patterns Significant correlation in arrivals from work i.e. significant peak load imposed by EV charging Significant opportunity to optimise charging as EVs will remain stationary over night

  6. Urban and rural representative LV networks Urban LV network Rural LV network Legend Distribution substation Dwelling Page 6 LV network

  7. EV & HP uptake levels and network control philosophy Representative networks … Reinforcement cost RC 1 RC 2 … RC 8 RC 3 RC 7 UK Distribution Network Reinforcement Cost Mapping UK LV and HV networks

  8. LV network overloads % of overloaded LV cable length % of overloaded D transformers

  9. Impact of EVs and HPs on the UK Distribution % of Transport and Heat Electrified

  10. Optimal EV response to electricity prices Price-based wind following may increase peak demand and overload distribution networks

  11. Observations • Paradigm shift from passive to active network management necessary to avoid massive distribution network reinforcement • Estimated benefits of Smart Metering due to reduced investment in distribution networks are between £0.5bn and £10bn • Benefits of additional functionality of Smart metering potentially very significant • Continuing with asset based business model? • There could be conflicts between energy supply and network business objectives; Distribution System Operator function needed?

  12. Benefits of Advanced Smart Metering for Demand Response based Control in UK Distribution Networks • Chin Kim Gan, Marko Aunedi, Valdimir Stanojevic, Strbac Goran, (Imperial College) • Dave Openshaw (UK Power Networks) Goran Strbac – UK – Session 4 – 0710
