  1. Grid Integration, Renewables, and Distributed Energy Resources Rish Ghatikar; Deputy Leader for LBNL Grid Integration Group http://grid.lbl.gov

  2. Grid Integration Objectives The electric grid, end-uses, renewables, and electrical vehicle fleets represents key efficiency and energy security objective. The Grid Integration Group conducts, develops, and demonstrates strategies and technologies to transform, coordinate, innovate, and integrate distributed energy resources and markets. Dynamic interaction between grid operators and energy consumers Support the grid integration of intermittent renewable sources, electric vehicles

  3. Grid Integration and Technology Innovation1 1. IEC Publicly Available Specification - IEC/PAS 62746-10-1 ed1.0 2. U.S. SGIP Catalog of Standards OpenADR specification (v1.0) by LBNL* Research initiated by LBNL/ CEC 1.DR 2.0 Pilots and field trials - Wholesale markets, ancillary services - Dynamic pricing, renewable, EVs - International pilots (e.g., Europe, Asia) 2. All end-uses and sectors OpenADR 1.0 Commercialization Pilots/field trials 2002 to 200620072008 2009 2010 2011 2012 2013 2014 OASIS EI 1.0 standards - OpenADR profiles 1. OpenADR Standards Development** - OASIS (EI TC), UCA, IEC 2. NIST Smart Grid, PAP 09, 19 1. OpenADR 2.0 deployment - International standardization (IEC) 2. USGBC national pilots 3. Codes (CA T24) 4. Transition plans 1 The Electric Program Investment Charge (EPIC) Energy Innovation Pipeline * OpenADR v1.0: http://openadr.lbl.gov/ ** Publication: http://drrc.lbl.gov/sites/drrc.lbl.gov/files/LBNL-5273E.pdf ** OpenADR v2.0 standards: http://www.openadr.org/specification 1. Adoption (100+ members) 2. Test/Certification (OpenADR 2.0***)

  4. OpenADR and Interfaces with End-Uses Enables California electricity providers to communicate targeted grid-services to customers using non-proprietaryand open standardized interfaces using a common language and existing communications (e.g., Internet). Control Strategies Physical Communications Pricing, Reliability Data Models Developed to meet CEC DR automation goals Low cost automation, technology for two-way secure communications, and controls integration

  5. Clean Energy Generation • Requires California utilities (IOUs and Municipal Utilities) to generate 33% of electricity from renewables by 2020 • 4GW of ancillary services for grid stability • Thermal generation : fossil fuel, high costs • Energy storage mandate (1.3 GW by 2020) Flexible and responsive loads can play an important role in ramping services International Experience: Denmark goal is 50% by 2020, plans for 100% in 2050

  6. Linking Grid with Customer-Side Distributed Resources Distribution Grid, Operations, Market, and Provider Challenges: Large and variable generation, decentralized energy resources(roof-top PVs, on-site and co-gen) Diversity of electricity markets, technology, and services Cost, cyber security, metering, communications interoperability New options: storage, EVs Customer Challenges: Different brand of equipment, distributed energy resources Ease of adoption and cost effectiveness Grid services requirements Optimized use of DER (e.g., Microgrids)

  7. Evolution of a Decentralized Energy Ecosystem • Electricity System is evolving from a centrally planned generation to a decentralized energy eco system • At various levels: demand, distribution, and transmission NIST Framework and Roadmap for Smart Grid Interoperability Standards, Release 2.0 DRAFT NIST Framework and Roadmap for Smart Grid Interoperability Standards, Release 3.0

  8. DR Automation and Renewable Integration • Market transformation towards a clean energy system and load flexibility • Challenges with high renewable generation: • Intra-hour variability, fast ramping (up/down), over generation and forecast errors Cost-effective flexible loads (costs only ~7% to 14% of grid-scale storage*) • Research Potential: • Identify potential issues with high penetration of renewables • Assess technologies (storage, generation, and DR, and their costs) • Consider interoperability standards and integration with DER (commercial, residential, industrial) *http://drrc.lbl.gov/sites/all/files/LBNL-5555E.pdf
