  • Electrification of society

    “Age of Coal”

    Extensive generation of electrical energy

    19th Century 20th Century

    Shift to New Electricity Age Challenges require rethinking:

    Unsustainable energy system

    The New Electricity Age

    Electricity will be the energy

    21st Century

    Sustainable energy system

    Paradigm shift in power grids: The New Electricity Age

    Unsustainable energy system

    “Age of Coal”

    “Generation and load

    electrical energy ”Age of fossil fuels”

    “Generation follows load”

    Challenges require rethinking: 1.) Demographic change 2.) Scarce resources 3.) Climate change

    “Energy system shifting”

    Electricity will be the energy source with a power grid as

    backbone.

    Integrated energy system

    “Load follows generation”

    Sector Infrastructure & CitiesDr. Rolf Apel

    *) ICT = Information and Communication Technologies Prosumer = producer and consumer

    “Generation and load closely coordinated”

    Supply island with stochastic load

    “Generation follows load” Integrated network, central

    generation, load stochastically predictable, unidirectional energy flow

    Coal hydro

    Coal, gas, oil, hydro, nuclear

    No environmental concerns

    “Energy system shifting” Increasingly decentralized,

    fluctuating generation “consumer” becoming “prosumer”

    Coal, gas, oil, hydro, nuclear,

    biomass, wind, solar

    Environmental awareness

    “Load follows generation” Central + decentralized generation,

    intelligence with ICT*, bi-directional energy flow

    Renewable energy sources (solar, wind, hydro, biomass),

    “clean” coal, gas

  • The Wind Power Challenge An illustrative case from Denmark

    Today (Nov-Dec 2011) Tomorrow (2020)

    28 % wind power

    50 % wind power power

    Sector Infrastructure & CitiesDr. Rolf Apel

    In the future wind power will exceed the entire demand of electricity in Denmark > 1,000 hours

    Wind power already covers the

    entire demand of electricity in Denmark

    in many hours

  • Smart Grid utilizes time flexible energy demand of consumers for an integrated optimization

    For traditional energy systems there is always sufficient controllable

    supply

    The "Smart Grid"

    Optimising all sources to balance supply and demand

    without impacting Quality of life

    Renewable supply capacity is uncontrollable - Storage and energy Management become key to network

    balancing

    Supply

    Peak Demand

    Available supply

    Using tools and techniques to manage supply and

    consumption to reduce risk

    without impacting Quality of life

    Using storage capability where supply and demand are

    imbalanced

    Making real time decisions to maintain availability and quality

    And uncontrollable consumption And the consumption needs to be flexible

    Available supply

  • Integration of Distributed Energy Resources into a Virtuell Power Plant

    Flexible Electricity Networks to Integrate the e Xpected ‘energy evolution’

    � The goal of the FENIX project is to proof that different Distributed Energy � The goal of the FENIX project is to proof that different Distributed Energy Resources (DER) can be aggregated and taken into the market as a single Virtual Power Plant (VPP) and that the Distribution System Operator (DSO) participates in the technical validation of the process.

    � The VPP performs the aggregation of the capacity of many diverse DER not only for day ahead marketing issues but also in real-time by collecting active and reactive power capabilities of the DERs from Local agents – thus allowing the VPP to provide also tertiary reserve for the TSO and ancillary services

    Sector Infrastructure & CitiesDr. Rolf Apel

    the VPP to provide also tertiary reserve for the TSO and ancillary services (reactive power control) for the DSO.

  • DEMO main highlights

    � With FENIX, the DSO has the opportunity to validate DER schedule (In Spain Generation schedules are validated only by TSO, considering the high voltage network)network)

    � For the first time a DSO has an application Voltage/Var control to optimize Distribution networks that consider DER outputs as control variables (non existing before)

    � FENIX has explored successfully the use of Back-up units to export energy into the network
