Therefore the integration of wind energy raises many challenges
• Technical challenges: Reaction of wind farms to dip voltages: contribution to grid stability. Voltage control: Transient and Steady State Short-circuit power Inertia
• System Operation challenges: Wind production program: effects on the deviations and use of
ancillary services: Primary Regulation Coordinated operation of the systems

The answer to those challenges requires the definition of technical requirements

SINCE 2004 THE WIND SECTOR AND THE TSO HAVE CLOSELY COLLABORATED TO DEFINE THOSE REQUIREMENTS IN A REALISTIC AND PRACTICAL WAY

An example; Technical Requirements for LVRT
Remain connected to the system in case of faults in the network (3/2/1 phase short circuits), allowing the protection system to clear the default (low voltage ride-through capability):
Voltage–time at the connection point to be supported (P.O.12.3) :
Power consumption (P,Q) limited
during fault and recovery.
Reactive power production during
fault
Lower restriction during 150 ms
after fault inception and fault
clearing
Lower restrictions for unbalanced
faults.

Renewable Energies in System Operation
Facilitate the maximum possible non-managed generation integration. Proposal to establish system operation measures which allow the
secure and stable operation of the whole electric system. Creation of the Control Centre for Renewable Energies (CECRE)
Control and supervision of special regime generation.Maximize RES production, but always keeping the electric
system in a secure state.

Conclusions
The collaboration between the Spanish wind sector and the TSO has proved to be most fruitful and fundamental towards guaranteeing the integration of wind energy in the power demand supply.
Both have learnt from the experience to overcome prejudices and to find practical and realistic solutions.
One of the consequences is that in Spain advanced technical solutions and many FACTS manufactures can be found.
The progressive growth of wind energy, reaching around 50% of the demand in some moments, will raise new challenges which will not be easy to resolve, but we are always working in a constructive way.
A GOOD REFERENCE FOR OTHER COUNTRIES: WORKING
TOGETHER IS THE BEST OPTION TO FIND EFFECTIVE SOLUTIONS
