INTRODUCTION
The challenge is clearly stated Control Wind
Power as a Conventional Power Source

• Considering this new scenario, the former
  paradigm of planning based on a small number of
  well known large power stations, it is not
  applicable any more.
• The stability of the fundamental electric
  parameters, frequency and voltage, must to be
  assured considering also wind power for this
  task.
• Active Power control is required for Frequency
  regulation as well as Reactive Power control is
  requiered for Voltage regulation.
• Strong planning and early identification of
  bottlenecks at European level are needed.
• Sustainable extension and reinforcement of the
  grid infrastructure.

POWER SYSTEMS REQUIREMENTS FOR HIGH WIND
PENETRATION

• Germany
• Reinforcement and extension of the current grid
  structure.
• Specification of new transmission and
  distribution grid codes.
• There is a need for the further extended and
  integrated control and management of wind power.
• Wind Farm Cluster Management System would allow
  grid operators to manage wind power in Germany
  according to the new scenarios.
• Off-shore wind power is expected to play a big
  role in the coming years.
• Phasing-out of nuclear power stations will
  require bigger volumes of controlled wind power.
• Source Deutsche Energie-Agentur - ISET

• Spain
• Technological adaptation of wind power
  generators.
• New regulatory developments (Operational
  Procedures)
• A new architecture of control centres solely
  devoted to monitor and control this integration
  (CECRE 2006)
• Specific tools able to asses in real time the
  System security with high penetration of
  renewable generation.
• The progressive displacement of conventional
  generation.
• Guarantee the proper running of protection
  systems.
• Source REE

• Portugal
• Grid capacity improvement.
• New grid codes to be developed.
• Technological adaptation of wind power
  generators.
• Considering the Iberian Market context, wind
  power and imports will reach off-peak load sooner
  than 2011.
• Implementation of the Wind Farm Cluster
  Management System is planned.
• The spinning reserve (frequency regulation) will
  be one of the most important challenges for wind
  power.

POWER SYSTEMS REQUIREMENTS FOR HIGH WIND
PENETRATION

• Balancing requirements.
• Fluctuations of wind power injections represent
  one of the main factors of demand for controlling
  and balancing power.
• Using wind power prediction systems.
• Active Power control is required for Frequency
  Regulation.
• The fulfilment of power and frequency control
  schemes implies the provision of primary and
  secondary power reserve.
• Grid codes of several countries are being
  updated in order to include the participation of
  wind power into frequency control markets
  (primary and secondary power reserve).
• Reactive Power control in required for Voltage
  Regulation.
• Grid codes have already issued operational range
  for the voltage and power factor at the point of
  connection.
• Fault ride through requirements.
• This issue is on the way to be solved (thanks
  to a huge effort from the whole sector), i.e. in
  Spain 81,3 of machines are adecuated for FRTC.

CONCLUSIONS

• Large scale integration of wind power makes new
  tools for grid operation necessary.
• Power system requirements for high wind
  penetration are clearly stated.
• The stability of the fundamental electric
  parameters, frequency and voltage, must to be
  assured considering also wind power (at large
  scale) for this task.
• The Wind Farm Cluster Management System (WCMS)
  has been developed at ISET.
• Provides TSOs and Dispatch Centres with an
  extended control of Wind Farm Clusters.
• Provides long and short term forecast at TSO
  and Wind Farm level.
• Its capabilities have been demonstrated in a
  field test in Germany.
• In the frame of the Wind on the Grid project,
  WCMS will be tested in Spain and Portugal during
  2009.
• Provision of balancing services and reactive
  power can be economically interesting when wind
  power plants become active partners in secure
  power system operation.
• Markets for these issues need to be developed.
