2014 Future Cities Conference / João Peças Lopes "Future Policies and Services – Electric Mobility and Demand Response" 2014 Future Cities Conference / João Peças Lopes "Future Policies and Services – Electric Mobility and Demand Response" Presentation Transcript

  • Future Policies and Services – Electric Mobility and Demand Response J. A. Peças Lopes (jpl@fe.up.pt)
  • 1. Introduction  2 Source: wikipedia.org  Production of electricity from renewable power sources will continue growing This generation is characterised by a variability characteristic The climatic changes will require a change in the mobility paradigm through a progressive integration of EV in existing fleets Source: wikipedia.org 
  • 1. Introduction Deployment of electric mobility only makes sense if renewable power sources will feed EV batteries Distributed generation and self generation is gaining importance   The variability of the renewable generation requires flexibility in the power system  load flexibility mainly  3 Impacts from Large Scale Deployment of Electric Vehicles F. J. Soares
  • 2. The Electric Mobility Paradigm  Controlled EV charging (and V2G) might be used to “shape” the power demand, avoiding very high peak loads and energy losses  EV storage capability might be used to avoid wasting “clean” energy (wind/PV) in systems with high renewables integration During the periods when renewable power available is higher than the consumption  Isolated networks might improve their robustness and safely accommodate a larger quantity of intermittent renewable energy sources If EV batteries are efficiently exploited as storage devices and used to mitigate frequency oscillations 4
  • 3. Framework for EV Integration into Power Systems Data flow between the aggregators and the “flexible EV” – Smart charging adherents - and other flexible loads (thermal loads)  Intra-day Markets Bids for selling the excess of energy or for buying extra energy. Aggregator Broadcast of information related with billing, tariffs and set-points related with charging rates and provision of ancillary services. Smart Meter µG EV is plugged-in and its owner defines the time of disconnection and the required battery SOC. µG Storage EV Charger 5 EV Moment of connection: bus where the EV is plugged-in, period during which the EV will be connected to the grid, required battery SOC in the end of the charging period and maximum/minimum power rates of the charging point. Each time interval of 15 min: battery SOC.
  • 4. Policy Implications The successful implementation of the electric mobility paradigm will require:  1. 2. Policies to incentivize the users adherence to controlled EV charging schemes 3. Policies related with the physical implementation of the concepts 4. 6 Policies to incentivize the acquisition EV Regulation policies for the activities related with the EV charging
  • 4. Policy Implications Policies to incentivize the acquisition EV: 1.  These policies should be implemented by the governments. Some possible examples:   Direct incentives for buying EV (difficult to adopt in the present situation)  Reduction of the “vehicle tax” for EV owners  Free parking facilities for EV in city centers  Allow the EV access to areas restricted to conventional vehicles  7 Tax reduction in the acquisition of an EV Allow EV to drive in “bus only lanes”
  • 4. Policy Implications Policies to incentivize the users adherence to controlled EV charging schemes and active load management: 2.  These policies should be implemented by aggregators. Some possible examples:   Recompense EV owners and consumers that are willing to provide system services (e.g. voltage and frequency control)  8 Provide energy at lower prices to the EV owners that adhere to smart charging ,V2G, and active load management Provide recompenses to increase the EV owners’ and consumers flexibility
  • 4. Policy Implications Policies related with the physical implementation of the concepts: 3. (strongly interrelated with the development of the Smart Grid concept)  These policies should be implemented by the entities in charge of regulating the electricity distribution sector. Some possible examples:   Policies related with the EV charging equipment (technical specifications of the private and public charging equipment, users safety and protection, etc.)  Policies related with the implementation of the communication infrastructure used to support the smart metering and the EV charging management activities and active load management  Policies related with the deployment of the equipment required to monitor the networks’ operating conditions (equipment owned by the DSO)  9 Policies related with the smart meters deployment Policies related with the deployment of the equipment required to manage the EV charging (equipment owned by the aggregators and/or by the DSO)
  • 4. Policy Implications Regulatory policies for the activities related with the EV charging control of flexible loads: 4.  These policies should be implemented by the entities in charge of regulating the electricity distribution sector. Some possible examples:   Policies to regulate the interactions between aggregators and system operators, including the data they need to exchange  Policies to regulate the aggregators/system operators access to the communication infrastructure  10 Data protection policies Policies to regulate the aggregators participation in the electricity markets
