Instituion Of Engineers Smart Grid Seminar Jul 16 2009

  1. 1. SMART POWER GRIDSThe Institution of Engineers (India), All India SeminarHyderabad, July 15-16, 2009SMART GRID –ECOSYSTEM ON DEMAND-SIDEWITH CUSTOMER INTEGRATION Satyam B @ NeoSilica
  2. 2. PRESENTATION OUTLINE  Energy Efficiency vs. New Generation  Customer Domain of Smart Grid  Smart Meters  Smart Energy Devices and Controls  Home Area Network  Smart Vehicle Integration  Local Generation and Micro-Grid Integration  Customer Integration  Availability Based Tariff (Real-time Pricing)  Demand ResponseSatyam B @ NeoSilica
  3. 3. ENERGY DISTRIBUTION IN US (%)Satyam B @ NeoSilica Lawrence Livermore National Laboratory
  4. 4. RAISING ENERGY RATES FOR CONSUMERS  Household energy bills going up steadily (UK example)  £ 580 5 years ago to £1,250 today  To £5,000 in 10 years (42% yearly increase)  Why are energy bills going up?  Rate caps are coming off  Energy usage is increasing dramatically, outpacing the supply World Energy need up by 50% by 2030 Of which – 20% India (25% China)  Utilities are investing heavily into Smartgrid activities  Utilities are trying to cover “peak demand” losses Utilities pay 2-3 times typical PPA price during peak demand  Increasing costs for energy generation  More Off-shore Exploration  Higher Processing Costs for Efficiency and Sustainability Compliance  Higher Generation Costs of Renewables  Higher Costs of Transmission and Distribution (answer=micro-grids)Satyam B @ NeoSilica
  5. 5. OVERVIEW OF CUSTOMER DOMAINSatyam B @ NeoSilica
  6. 6. SMART METERS  Meter Reading Interfaces  Optical Port – requires Optical to Electrical conversion (not reliable and long range)  Wired RS485 – more reliable  Wireless Mesh WiFi (Zigbee/ZWave) – integrate into Home Area Network  Wireless GPS/GPRS – data plans are expensive over time, expensive mobile cards  AMI (Automated Metering Infrastructure)  AMR – meter reading – touch free, pass by, over network  Also provide bi-directional communication to support  Remote Disconnect-Connect  Prepaid  Detect unauthorized usage  Power Outage indication  Interval or Time-of-Use Rates  Key difference – Networked system – not a standalone unit  Key Players  Standard models: GE, Landys & Gear, Echelon, Itron, Smart Meter, …  Customizable: HPL Socomec, Neptune, Chinese manufacturers, …  Larger implementations – Italy (27 million)Satyam B @ NeoSilica
  7. 7. SOLUTION SCOPE Demand Response User AMI ++ Conservation + * Customer +++ AMR * Remote Disconnect Participation * Local Generation Smart Meters * Outage Detection * Energy Gateway Integration Meter Reading * Utility Portal * HAN * User Conservation * User Portal * Mobile * User IHD ServicesSatyam B @ NeoSilica
  8. 8. METER TO BACKEND SERVER CONNECTIVITY Meter to Backend Server (Utility Data Center) Connectivity Options  Option 1: Meters  Data Concentrators  Backhaul Network  Backend Servers  Meters  Data Concentrator on a Pole  PowerLine (Echelon, …)  Data Concentrator  Backend Servers  Any IP Network, dedicated or shared – wired (MAN, WAN, BPL) or wireless (WiFi, WiMAX)  Option 2: Meters  Backend Servers  Mobile Option (GSM/GPRS, Carriers offering m2m data plans)  Option 3: Meters  Energy Gateway  Generic Broadband  Option 4: Meters  Energy Gateway  Concentrator  …  Secure Communication between Devices (m2m)  Encryption, integrity check, access control  Tested to be tamper/hacker proofSatyam B @ NeoSilica
  9. 9. HOME AREA NETWORK (HAN)  Set up a network at Home to connect  Smart Meters  Energy/Network Gateways  Energy Appliances and their Smart Controls (external or built-in)  AC with Thermostat, Lighting System, Washer that responds to DR/TOU rates  Display Devices (Home Automation Screen, TV, Home Theater, …)  Local Machines, PC/Mobile (if required) Networking Options (dedicated or shared, combination of)  Wired  PLC (Powerline Carrier Communication)  HomePlug (1.0 and AV), Echelon  RS485 (serial)  Ethernet  Wireless  RF Mesh WiFi  Zigbee getting more popular with industry push (low power, lower range)  Zwave has superior technical features, but not yet a leader  WLAN 802.11  GSM/GPRSSatyam B @ NeoSilica
  10. 10. ENERGY DEVICES AND SMART CONTROLS  Major Energy Devices  Air Conditioners  Rapidly growing market  Need Thermostats or advanced controls  VRF Central AC  Efficient zoning  Built-in Energy Control  CFC free coolant  Hot Water Heaters/Geysers  Reduce Wastage  Water Pumps (Sumps)  Washing Machines and Dryers  Lighting – Smart Systems to Manage  Residential Lighting  Commercial and Public Utilities  Home Automation with Energy Management FeaturesSatyam B @ NeoSilica
  11. 11. INTEGRATE WITH TIME OF USE RATES  Integrate Customer’s Choice with Utility’s TOU Rates  From the Utility side:  Read meters dynamically in real time  Adjust TOU rates for the neighborhood  Send back Unit Prices to the meter – for local retrieval on HAN  Optimize energy usage – based on peak and off-peak rates  Start washer/dryer at night – when off peak  Stop motors and geysers during peak times  Air Conditioners – adjust thermostatsSatyam B @ NeoSilica
  12. 12. LOCAL/MICRO-GRID INTEGRATION  Local Generation (Solar, Wind)  Monitor and integrate – solar/wind generation  Net metering  Monitor for efficiency  Energy Management to match GenerationSatyam B @ NeoSilica
