  2. Wind generation in Poland Study analyzing system limitations of WG operation in Polish Power System Scope of study Assumptions Results Conclusions Scope of presentation

  3. Installed power: around 800MW Issued permissions for grid connection: more than 12000MW (end of 2009)compared to 4000MW in the beginning of 2008 EU directive 2009/28/WE and Energy policy in Poland by 2030show strong need for wind generation development (according to Policy Poland needs: 3400MW of WG in 2015 and 6100MW in 2020) Tasks to do for Polish Operators: enable fulfillment of obligations and coordinate Polish Power System and Wind Generation development no guarantee to absorb all power from WG with issued permissions for grid connection before grid reinforcements not all connecting conditions will result in working WG Wind generation in Poland

  4. Influence of wind generation on power system performance and operation Study started April 2008 Contractor: Instytut Energetyki Oddział Gdańsk Vendors: PSE Operator SA (TSO) ENERGA-Operator SA (DSO) ENEA Operator Sp. z o.o. (DSO) Setting up a study } operate in area where the most connection permissions are issued

  5. Types of analyses: Power flow Short circuit Dynamic Economical Scope of Study Study area • Analyzed area: • Whole EHV grid • Selected 110kV grid • Influence of WG in Germany

  6. Finding answers to the following questions: What amount of power of wind generation can operate in northern Poland without significant network investments? What is necessary to enable more WG connection? Assumptions

  7. Increased power demand Grid development: EHV limited development in studied area (not associated with wind) 110 kV in accordance with development plan up to 2011 Wind generation – collected data Working ~450MW (now ~800MW) With connection conditions ~8650MW (now ~12000MW) including 2100 MW connected to MV network Influence of wind generation from Germany Assumptions model development

  8. First approach – before data collection: Take into account WG with connection conditions Look for possibilities to connect more WG Final approach – after data collection: Take into account WG with connection conditions Change WG in range 0-90% of nominal power All WG treated equally Global approach N-1 analysis for the whole system In EHV grid In 110kV grid Assumptions – approach

  9. Wind generation - locations 8150 MW The most attractive area for investors

  10. Maximum loadings recorded in n-1 analyses summer light load model with WG 0-90% Results - EHV network

  11. Results - EHV network Number of observedloadings > 100% Prior to this level, WG is limited by other factors  Number of observedloadings 80-100%

  12. Results – 110 kV network Maximum loadings recorded in n-1 analyses summer light load model with WG 0-90%

  13. In present state of the system development: Maximum acceptable WG results from: number and level of overloadings operators ability to cope with it by reducing WG Maximum WG in northern and north-western part of Poland: 4200MW (~50%) resulting from EHV network limitations EHV network development is necessary to enable more WG connections and operation Parallel operation of EHV and 110kV – big mutual influence on required investments and acceptable level of WG Conclusions

  14. In present state of the system development: Influence of system balancing needs on maximum WG in light load demand Preliminary dynamic results (not enough data for future WG installations) show no negative influence on transient stability and voltage recovery around 1000MW can be lost after faults in EHV grid (mainly connected to MV network) Conclusions

  15. Elimination of barriers limiting WG connection to PPS: Grid development , first off all EHV grid E.g., significant increase of maximum WG in system with new double circuit line north-south Dunowo-Żydowo-Piła-Plewiska:up to 5800MW (~70% of analyzed power) Conclusions

  16. Elimination of barriers limiting WG connection to KSE: TSO and DSO update their development plans to enable connection of more WG and fulfill requirements of EU – in progress PSE Operator in 2009 updated system development plan up to 2025 ENERGA-Operator, in the study, updated grid development plan up to 2018 Improvement of balancing ability of the system More units with wide range of active power operation More units able to respond quickly to changing power balance Less units in must-run mode Obligation to WG: to fulfill requirements of grid code (to avoid problems other power system experience now) and update connecting conditions issued before 2006 Learn from experience of other countries Conclusions
