Introduction
Large number of PEVs have potential to provide significant grid
benefits
• 1.5M PEVs in 2023 charging / discharging at 6-7kW constitutes 10,000 MW of capacity
for distribution and ancillary grid services
• 20% of 1.5 million PEVs could provide 2,000 MW capacity at a value of $350 million
per year in capacity constrained urban areas (i.e. Los Angeles basin)
Vehicle to Grid (V2G) Technology
• Energy storage resource for AB2514 Energy Storage Procurement Mandate (1.3GW)
and at no capital cost to IOUs
• Generation balancing resource for intermittent renewable generation - “Duck Curve”
• Grid services at DSO and ISO level
Grid-connected PEVs with V2G help improve air quality, reduce grid
stress, and increase grid reliability and stability
• Air Quality through increased transportation electrification through incentives
• Grid Stress through acting as Flexible DR or ‘balancing resources’ in aggregated
manner
• Grid reliability and stability through provision of ancillary services

Issues/Challenges
 Inconsistent data communication approaches among Utilities and PEVs
 Lack of situational awareness of the PEVs relative to distribution grid state
 Fragmented technology and standards inhibiting interoperability and preventing
inclusion of V2G resources
 Capability for on-vehicle inverters to meet Rule 21 performance and
interconnection requirements
– Certification of PEV inverter system to UL and IEEE requirements
– Site authentication/authorization requirements due to roaming of PEVs
 OEMs do not see value to end customers
– Prevents realistic assessment of PEVs as Distributed Energy Resources (DERs) with
a path to volume production
 Learnings to date based on controlled experimentation for ancillary services
– Ancillary services is limited capacity market - minimizes utilization and value of V2G
– V2G must be demonstrated outside the frequency regulation market to represent a
sustainable long-term net benefit for utilities and ratepayers
 Requires dynamic real world distribution grid integration

Project Scope / Goals
Innovative Automated Distribution Load Management via Open Standards
• Use of Open Standards: SAE J1772, J2836/3, J2847/3, J3072 (Indusry-first
implementation), J2931/4, J2931/1, IEEE2030.5 (SEP2), OpenADR 2.0b
• Local transformer real time monitoring and load management control
• SEP2 /IEEE 2030.5 based comms feature sets and control algorithms: Load Control from EMS
and DSO / ISO to PEVs
Implementation and Testing of Dynamic Use Cases
• Automated transformer management based on localized transformer constraints – residential
/ fleet environments
• DSO aggregated PEV DR and load management dispatch utilizing local transformer condition
information
• ISO ancillary services dispatch (simulated) control communications
Quantify costs and benefits from the customer, utility and societal perspective
• Apply E3’s DER Avoided Cost and cost-effectiveness methodology adopted by the CPUC
• E3’s REFLEX and GHG Pathways modeling to quantify the value of V2G under high
renewable/low carbon scenarios
• EPRI ESVT Extension for V2G services valuation
• OpenDSS: quantify the physical and electrical impacts on the distribution system to ID
hotspots for localized DR; Deferred Distribution Upgrade Assessment

Work Plan and Recommendations
 2016 dedicated to technology development and systems
integration
 2016 for running experiments and data collection / analysis
 Currently gearing up to understand and implement SAE
J3072 with EVSE and PEVs – Actively looking at 3 OEMs to
provide / loan vehicles
 Where do we go from here?
– Scale pilot for ALL VGI Use Cases including V2G essential to
validating consumer behavior and valuation assessment
– Technology will work itself out – for commercialization, OEMs and
equipment providers need to understand programs that capture the
value to utility and incentivize PEV owners
