Our key tasks Changes

Key tasks and roles of TSOs have changed drastically since TenneT

was established in 1998.

Past Present

• Stable, predictable (price-

driven) energy generation

• Maintenance and (limited)

replacement

• Focus on technology

• Local markets, separate price

zones

• National focus and regulation

• Fluctuating energy generation

(solar/wind)

• Large-scale new construction of

generation and transmission

capacity

• Technology and market

• North-West European market,

price convergence

• Grid planning and regulation at

European level


Offshore developments NL A cost reduction of 35 to 40% and achieving the 2023 targets is only

feasible with a structured approach, careful planning and

standardization

• Lower financing costs for TSO

• Double connection

= redundant

= higher efficiency

• Fewer dune crossings:

environmental benefits and cost

reductions

• Standardization, learning effects

and purchasing advantages: cost

reduction

• Prepared for use of 380 kV cable

in the near future

Grid security calculations ready for future changes

• Challenge is less predictable flows and more changing flows

(perhaps different impact caused by micro grids)

• From Day Ahead operational planning towards Intra Day

planning ( the link with the micro grid for planned MW

exchange with higher Voltage level)

• Intra Day processes are running continuously and repeat

hourly

• ENTSO-E is preparing a mandatory Intra day Process for

Continental Europe

• Operational Planning Timeframe goes towards close to real-

time

• SCADA and operational planning process need to become

one continous process


SCADA-EMS Development for future changes

• Challenge is less predictable flows and more changing flows

• Operational Planning Timeframe goes towards close to real-time

• Size of the grid with impact on TSO’s area, becomes larger

because of loop and transit flows and multilateral trades and

resulting flows

• SCADA-EMS and operational planning process need to become

one continous process

• SCADA –EMS in the future including functions like:

• Dynamic Line Rating

• Realtime Predictable Voltage stability

• PMU’s and WAMS

• WAMPAC

Examples Disturbance in Zeeland, September 2009. Recorded by Amprion.


WAMS detects North-South oscillations


PMU’s detect loss of DC cable Which causes Voltage and Flow changes but no oscillations


Future Developments • Online test phase (on going)

• Increase number of PMUs in the grid

• Identify the need for more PMUs, dependent on application/goal

• Connect to PDCs from other TSOs

• Assessment of Risks & Challenges

• Reliability of communication channels

• Security of data transmission (communication to PDC)

• Defining remedial actions for operations

• Training of operators on dynamics

• Back-office testing of the system

• Integration of PMU information in system operations

• Integration of system dynamics simulations in operational planning

• Integration of dynamic information in the control room (EMS integration)


Conclusions & Recommendations

Agile processes are needed in Operational Planning and Realtime processes

Increasing dynamics challenges of interconnected power system operation request detailed analysis:

Enhanced dynamic modelling

Timely well-synchronised and high-resolution measurements

Permanent system monitoring

Comprehensive up-to-date expertise within TSOs

TenneT is Europe’s first cross-border grid operator for electricity. With about 21,000

kilometres of (extra) high-voltage lines and 36 million end-users in the Netherlands and

Germany, we rank among the top five grid operators in Europe. Our focus is to develop a

North-west European energy market and to integrate renewable energy.
