Southern California Edison Distribution Resource Plan Stanford/SLAC VADER Workshop March 30, 2016 Erik Takayesu, P.E. Director, Electric System Planning and Modernization Energy Policy Drivers in California Assembly Bill 327 (AB 327) Senate Bill 350 (SB 350) • Distribution Resources Plan (DRP) • Net Energy Metering Successor Tariff • Residential Rates Reform • • • • • 50% RPS by 2030 50% increase in building EE by 2030 Integrated Resource Planning Transportation Electrification Governor’s strong support California’s Energy Policy primarily driven by decarbonization Technology-promoting policies Disadvantaged Communities • Integrated Distributed Energy Resource (IDER) proceeding • 1,325 MW Energy Storage mandate • Transportation Electrification (e.g. SCE’s Charge Ready program) • Expand opportunities for low-income, environmental justice and other underserved segments to access clean energy resources 2 SCE’s Guiding Principles 1. Promoting customer choice and customer engagement are key objectives 2. The distribution grid can play a key role in reducing carbon in California 3. Safety, reliability, and resiliency must remain paramount objectives 4. Costs of electric service must remain affordable and equitablyapportioned to customers 5. Competitive processes for the selection of DERs should be utilized to the greatest extent possible 3 Distributed Energy Resource Proceedings Distribu1on ResourcePlan Proceeding (Tracks1–3through early2017) Integrated DistributedEnergy Resources Proceeding (Phase1through 8/2016) • Integra1onofDERsinplanningand opera1ons • Iden1fica1onofop1malloca1onsand valueofDERs • Developmentoftoolsandmethodologies • Fielddemonstra1ons • DeterminehowDERscanmeetsystem needs • DevelopsourcingframeworkforDERs • AlignDERcost-effec1venessframeworks Scope elements • Integration Hosting Capacity • Locational Net Benefits • Data Access • Planning alignment • Grid Modernization Investments; integration into General Rate Case Expanded scope • Competitive solicitation framework: product definition, rules, plans, standard contracts, “review groups,” and valuation methodology • Utility roles, business models, and financial interests • ConsiderlocalizedDER incen1ves 4 DER por(olio solu-ons fulfill required performance a7ributes, however are not en-rely equivalent DER portfolios bring different dynamics than traditional infrastructure Availability Tradi&onalinfrastructure DERpor5oliosolu&on Accessiblewhenrequired Compe1ngpriori1esforusecan affectavailability,maybeserving customerneedsorwholesalemarket Dependability Installedforspecificuse andperformfunc1onas specified Dependsonotherfactorssuchas weather,1meofday,andcustomer processdemands Durability Well-definedand understoodassetlife Customersmaydecidetoexit voluntaryprograms,failtomaintain resources,ormove Flexibility Increasedopera1ng op1onsduetoinherent capacitymargin Maximizesu1liza1onofexis1ng infrastructure,howeverlimits opera1ngpossibili1es A modernized distribu-on planning process iden-fies grid needs and DER solu-on a7ributes Planning processes need to be modernized to integrate DERs, leveraging new tools, data analytics, and visualization capabilities Develop forecasts, assump&ons& scenarios • Integratedforecast • Load • Distributed Genera1on • DemandResponse • EnergyEfficiency • ElectricVehicles Perform distribu&on planning assessment • Thermal • Voltage • Protec1on Loca1onaldistribu1onneedsand associatedtradi1onalsolu1ons Iden&fyareas whereDERs havegreatest benefit DetermineDER opera&onal requirements (a?ributes) • Screenprojectsthroughadeferral frameworktoensuresystemreliability • Iden1fyfeasibleDERloca1onsand associateda]ributerequirements • Quan1fyrangeofloca1onaldeferralbenefits 6 Perform compe&&ve sourcingfor DERdeferrals • Exis1nghos1ngcapacity • Opera1onalrequirements • Performancemetricsand valida1on • Otherrelevantinforma1on Grid reinforcement and moderniza-on is required to maintain reliability and realize DER opera-onal capability DER installation for additional uses increases grid operation complexity; when DER portfolios are relied on as part of reliability, that complexity escalates Monitor Analyze Control Situa1onal Awareness Forecas1ng(short andlong-term) Distributedand centralized Resourceoutput/ status Powerflowand direc1on Distribu1onload flowanalysis (shortandlongterm) Interconnec1on tools Gridstate es1ma1on ISOdispatch coordina1on Autocircuit reconfigura1on Voltage Circuit configura1on Capacitorbank switching DERopera1ons disatpch Op1mize reliability Op1mize economics Powerflow op1miza1on Poten1almarket opera1onlayer ontopof reliability op1miza1on Voltage op1miza1on Adap1ve, bidirec1onal protec1on Customerobjec1ves Customerobjec1ves,smallvolumeofDERprovidinggridservices Customerobjec1ves,increasingrelianceofDERprovidinggridservices Customerobjec1ves,relianceofDERprovidinggridservices,priori1zedbyDERcosts Enabling an Integrated and Flexible Distribution Grid 8 Thank you.
