4 Seite 4 Dipl.-Ing. Alejandro J. Gesino - ISET e.V.  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. The challenge is clearly stated: “Control Wind Power as a Conventional Power Source” INTRODUCTION

5 Seite 5 Dipl.-Ing. Alejandro J. Gesino - ISET e.V. 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  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.

6 Seite 6  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.

11 Seite 11 Dipl.-Ing. Alejandro J. Gesino - ISET e.V.  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  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.
