Transcript

  • 1. © Sentec 2012© Sentec 2007 MAKING A ENERGY OF DIFFERENCE SMART WORLD TECHNOLOGIES Smart meter functionality – for today and the future 4th Annual Smart Grids & Cleanpower 2012 Conference 14th June 2012 Cambridge www.cir-strategy.com/events SLIDE 1
  • 2. Overview© Sentec 2012 SMART ENERGY TECHNOLOGIES•  UK smart meter deployment is starting now•  SMETS 1 published in April –  Smart Metering Equipment Technical Specifications –  Defines minimum functionality for meters and displays•  Key design considerations beyond SMETS –  Total cost to install, not just asset cost –  Communications performance –  Future-proofing the hardware –  Models for meter firmware and applications SLIDE 2
  • 3. UK status June 2012© Sentec 2012 SMART ENERGY TECHNOLOGIES SLIDE 3
  • 4. Issues in deployment and commissioning© Sentec 2012 SMART ENERGY TECHNOLOGIES•  Initiating a new positive relationship with customer –  Trouble-free on-time high-quality process –  Belief of installation team that it is a good system•  Consider total cost of (hardware + installation) –  More expensive hardware could improve installation •  Less time on site •  Lower risk of a failed installation and subsequent revisit•  Installation efficiencies make material cost savings –  10% saving in install time = £157m saving for the UK rollout •  Based on April 2012 Impact Assessment costs SLIDE 4
  • 5. WAN and HAN performance© Sentec 2012 SMART ENERGY TECHNOLOGIES•  Strongly influenced by property characteristics –  Location (overall WAN coverage) –  Meter location (indoor, meter box, semi-concealed) •  Distance between gas and electric meter –  Construction materials (timber, brick, stone etc) –  Type of dwelling (apartment, detached property etc)•  Minimise chance of failed installation –  Collect information on the meter locations and properties –  Use coverage maps for WAN –  Provide tools, feedback and alternate options for installer SLIDE 5
  • 6. Beyond installation – future proofing© Sentec 2012 SMART ENERGY TECHNOLOGIES•  Challenge of rapidly evolving markets for a long lifetime asset –  Maintaining functionality –  Predicting total cost of ownership and ROI•  International experience – it isn’t easy! –  Italy –  Australia/New Zealand –  Sweden•  But it is possible –  E.g. In-field upgrade of FlexNet meters in USA SLIDE 6
  • 7. Choosing the right smart meter© Sentec 2012 SMART ENERGY TECHNOLOGIES•  Traditional •  Additional Smart specs –  Hardware cost –  Which processor –  Performance stability –  How much memory –  Reliability –  Which OS –  Day 1 functionality –  WAN hardware capability •  Standards –  HAN hardware capability •  Protocols –  Metrology capability •  Compatibility –  User interface capability Consumer analogy: –  Upgrade processes Consumer analogy: buying a mobile –  Ease of configuration buying a Smart phone, 10 years ago Phone today SLIDE 7
  • 8. Requirements trends to consider© Sentec 2012 SMART ENERGY TECHNOLOGIES•  Core functionality –  Increasing complexity of Time of Use –  Credit, Prepayment and PAYG operation –  Increasing resolution of load profiling –  User interface with smart meter system•  Future applications –  EVs –  HEMS –  Microgeneration –  Demand response appliances SLIDE 8
  • 9. Recent history in smart meter evolution© Sentec 2012 SMART ENERGY TECHNOLOGIES•  Code growth 1000 Code growth in US market from 2002•  Non volatile storage 100 Code size (kB) –  Even faster than code size 10•  Increasing frequency of communications –  From monthly to hourly 1 2001 2002 2004 2005 2006 2008 2009 2010 2012 2013•  Increasing communications bandwidth –  Larger volumes of data•  Security requirements –  Increasingly heavyweight SLIDE 9
  • 10. Writing meter firmware applications© Sentec 2012 SMART ENERGY TECHNOLOGIES•  Traditional •  Smart –  Meter vendor writes –  Meter vendor provides firmware core OS •  Using subcontractors •  Including core metrology •  Licensing in stacks etc •  Including hardware drivers –  No third party access –  Applications for everything •  Code is proprietary else •  Code often monolithic •  Third parties can develop •  Security issues •  Defined interfaces –  Slow code evolution •  Independently installable •  Limited set of resources –  Meter vendor certifies •  Limited customisation per customer SLIDE 10
  • 11. Predictions© Sentec 2012 SMART ENERGY TECHNOLOGIES•  Small choices in design will have BIG impact on installation•  Expect unknown applications – for home and grid management•  Expect third party app development (already happening in US – ‘Green Button’ initiative) SLIDE 11
