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”


*) ICT = Information and Communication TechnologiesProsumer = producer and consumer

“Generation and load closely coordinated”

Supply island withstochastic load

“Generation follows load”Integrated network, central

generation, load stochastically predictable, unidirectional energy flow

Coalhydro

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 ChallengeAn illustrative case from Denmark

Today (Nov-Dec 2011) Tomorrow (2020)

28 % wind power

50 % wind power power


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 demandof 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

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


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
