Presented by: Tommy Carpenter Computer science University of Waterloo
Outline • The grid has real problems • that smart grids can solve • These problems are intrinsic and difficult • so progress has been slow • Three areas where changes are imminent are solar, storage, and sensing • examples of our work in these areas
…is old Post-war infrastructure is reachigEOL
…inefficient US DOE: http://www.southeastchptap.org/cleanenergy/chp/
…poorly controlled • Electrons are notaddressable Perception Reality
…without storage (mostly) Needed capacity http://ieso-public.sharepoint.com/
Current grid Smart grid • Renewables/low carbon • Storage rich • Sensing rich • Control rich • Efficient • Decentralized High carbon footprint Little to no storage Poorly measured Poorly controlled Inefficient Centralized
…but Consumers & Utilities lack incentives Savings of 10%: $5-10/month Utilities make $$ regardless
hence slow progress: -Demand response: onlytime of use pricing -Grid storage: tiny -Smart buildings and homes: demo stage -Microgrids: rare -Electric vehicles: early mainstream -Security and privacy: mostly missing
Three inflection points • Solar • Storage • Sensing (and control)
Storage research, investment growth Global investment to reach $122 Billion by 2021 – Pike Research Some grid storage Largest change: EVs LiON Declining. $600 down to <$200
Sensing & Control Grid Home Pervasive Michigan Micro Mote
Insight: Grid-Net Isomorphism Grid Internet Variable bit-rate source Bits Buffer Communication link Tier 1 ISP Tier 2/3 ISP Congestion control Renewable Source Electrons Storage Transmission line Transmission network Distribution network Demand response
Sensing: auto thermal comfort (Spotlite) • Uses ML to learn comfort levels, occupancy patterns • Pre-heat prior to occupancy periods, lower heat afterwards • Cooling
Sensing: preserving data privacy -Certification and Validation App Store -Data collection -Data access control -Application framework App API VEE -Integrating cloud storage -High density hosting Host Each user’s data is stored and processed (by apps) in user-owned virtual execution environments, enabling: Gateway Data ownership Data privacy Data applications
Sensing + Storage: distributed charging - Goal: fairly allocate resources during congestion periods - Our work: distributed, model free and real time via congestion signals - Prior work: centralized, perfect network knowledge, day ahead, • 1 EV = 5 homes • Creates hotspots • Real-time AIMD control of EV charging rate • Solution is both fair and efficient
Solar + Storage: Solar EV Charging • Base case (no solar): try meeting all charging deadlines • - If infeasible; perform fair allocation • Integrate solar to reduce emissions while ensuring same (or greater) utility
Solar + Storage: ROI, EROEI of Solar Systems w/ Storage -Advanced modeling of stochastic inputs, comprehensive battery model
Storage: EV Sentiment Analysis • EV Ops gauged using: • Field Trials: Expensive = usually short, not many participants • Surveys: Hard to target • But lots of opinions buried in discussion forums!
Storage (EVs): Vehicle Access networks for EV owners • - Range Anxiety: long trips not possible yet. Prohibitive to owners • without another car. • - EV owners sometimes need access to ICEVs • - Solution: operate some form of multi pool network (a carshare) • - Can be integrated into dealership, operated by gov, • community nonprofit, etc. • - Regardless of business model, sizing/managing the fleet is hard
Storage (EVs): Vehicle Access networks for EV owners Challenge: Ensure maintained over time Demand patterns constantly changing, non-stationary, arbitrary
Sensing + storage + solar: WeBike • A fleet of 25-30 ebikes on campus • Tons of sensors, data collection • Bikes now being deployed!
Conclusions • - We are networking and smart grid researchers exploiting similarities between the net and grid • - Currently working in 3 main areas: • Solar • Storage (EVs) • Sensing/Control
