DIW Electromobility Project: Modeling Power Plants and Market Analysis

Explore how electric vehicle charging impacts power plant unit commitment, CO2 emissions, and market dynamics. DIW Berlin's team conducts in-depth studies on thermal power plants, reserve energy markets, and charging infrastructures. Current projects cover renewable energy integration and EV infrastructure viability. Model scenarios include diverse charging systems and user profiles for comprehensive analysis.

  1. Kick-off Meeting at IHS Vienna Andreas Schröder Vienna, 14 June 2012 DIW electricitymarket model fortheproject DEFINE-Electromobility+

  2. Part 1 – DIW Modeling Background Electromobility+ DEFINE

  3. Deutsches Institut für Wirtschaftsforschung DIW Berlin founded in 1925 180 Employees (100 researchstaff) Knownformacroanalysis but strong in energymarketanalysis Department Energy/Transport/Environment Electromobility+ DEFINE

  7. Motivation andobjectives Research question Effect of EV charging on power plant unit commitment Power sector CO2 emissions Is V2G in reserve markets a viable business model? Model • Unit Commitment Model as MILP in GAMS • Includes storage, DSM and reserve markets Results • Dispatch • CO2 emissions • Market prices • V2G storage use in conventional and reserve markets Electromobility+ DEFINE Project

  11. Scenarios - chargingsystems Home charging Schuko-outlets AC 220 V; 16 Amp 3.6 kWh/h Little use for reserve energy markets ? • Demand profiles also depend on chargingsystem, degreeofhybridizationand V2G-availability Public Charging AC • 3-phase AC • 400V; 16/32 Amp • Up to 40 kWh/h • Good use for reserve energy markets ? Public Charging DC • DCChademo Standard • 400/500V; 125 Amp • 62.5 kWh/h • Ideal use for reserve energy markets ? Electromobility+ DEFINE Project
