So….• LCL is an emulation of the future challenges that will impact urban electricity networks focussed on London and the LCZ’s.• Aligned with stakeholders’ objectives to reduce C02 emissions through energy efficiency, electric heat and transport, and distributed generation.• Partnering with National Grid, energy suppliers and commercial aggregators to explore commercial innovation.• Partnering with proven ICT and smart grid solution providers to ensure complementary technological innovation.• Integration of technological and commercial innovation at scale involving direct interaction with real customers and communities.• A dedicated learning laboratory to ensure robust analysis of results and effective sharing and dissemination of learning – TO ALL 25
Context Radical shift in UK energy policy; 35% electricity from renewables by 2020. Electricity generation decarbonised by 2030. 80% reduction in carbon emissions by 2050. Potential impact on our network (if we do nothing); Higher peak demands. Thermal and voltage constraints. Higher fault levels. Less predictable load cycles. Higher losses. Potential of a doubling of demand by 2050 without ‘smart’ intervention. Costly and disruptive capital investment. 26
SUMMARY - is it smart? The current established ways of managing networks will quickly become unsustainable. We have built a strong foundation for innovation – as good if not better than other DNO’s. Any expertise developed through this process must be transferred and embedded into the rest of the business, partners and professionals, government, policy makers. Commercial innovation, strategic partnerships and customer engagement is crucial. Must have embedded this philosophy into our business by RIIO-ED1. Enable us to shape our business and enable us to become a top performing company under the new regulatory framework (RIIO-ED1). This is the beginning of a new era in the management of electricity networks and asset management, future is here future is now!! 27
In summary…Low Carbon London will:• help London lower its transport and energy-related carbon emissions• help Londoners reduce their energy bills and build a low carbon future• provide an example for others in the energy industry to follow• establish sustainable communities where: – people want to live and work – companies want to do business – other cities look to for inspiration Low Carbon London tackles the UK city with the highest carbon emissions and provides a ‘power’ learning showcase for other cities
Learning Lab infrastructure and analysis Dr. Mark Bilton 06/07/2012
Two key goals• To understand how the distribution network can facilitate the adoption of low carbon power generation, both locally and nationally;• To understand the extent to which decentralised generation and demand side management can be utilised to provide cost effective alternatives to system re- enforcement.
LCL’s holistic approach• Network – Integration of HV and LV network data (first time for London) – Considerable data cleansing• New loads – Heat pumps – Electric vehicles• DG – CHP, PV• DSM (Residential and I&C) – Efficiency – DR (Contractual, behavioural and automated)• Implications for control and planning (Including increased wind generation)
Outputs: reports overview Data Load profiles Interventions Meta analysisavailability and quality DERs Power Control/wind-Smart meter I&C DG and DR quality twinning Efficiency on Residential Network tariff response Planning profiles State DERs on Residential Resilienceestimation profiles tariff attitudes Smart Commercial EVs on profiles appliances arrangements
Research approach• Measuring existing profiles and power flows• Characterising future network power flows• Characterising interventions• Modelling combined interventions on network• Investment costs modelling• Supply side models for carbon emissions analysis
Instrumentation• 5000+ meters around LPN.• Sensors and RTUs to measure all LV ways in LCL Low Carbon Zones (Brixton, Queens Park, Merton).• Eventually all HV ways.• Technology specific monitoring with ‘3G’ meters or power quality analysers.
