The project entitled "Wind power plants in dynamic states of the power grid" (Access project No: 194) conducted under the ERIGrid 2.0 Lab Access programme has demonstrated significant benefits for both user groups and hosting organization. By offering access to cutting-edge laboratory facilities and expert support, the programme accelerates research and development, thereby fostering scientific advancements. Key Outcomes and Benefits: 1. Advancements in Islanding Detection: • Conducting comprehensive scheduled tests on island operation of converters in wind power plants was a notable achievement. • Physical laboratory experiments provided valuable insights for detecting island operations, surpassing the reliability of computer simulations. 2. Voltage Fluctuation Compensation Research: • Initial simulation studies confirmed the feasibility of using converter reactive power for rapid voltage fluctuation compensation. • Subsequent laboratory tests validated these assumptions, proving the technique’s effectiveness. 3. Holistic Test Description (HTD): • HTD was instrumental in organizing work by defining test objectives and evaluation criteria. • It facilitated effective planning and coordination, leading to efficient resource management and adherence to deadlines. • The test table created during HTD preparation required minimal modifications, demonstrating its robustness and adaptability. • Technical Annex and HTD canvas are presented in Appendix A. 4. Challenges and Solutions: • A significant challenge was ensuring the safe island operation of converters, given the rapid changes in voltage and frequency. • Pre-experiment simulations confirmed the effectiveness of protective measures, ensuring equipment safety during tests. 5. Hardware-in-the-Loop (HIL) Technique: • HIL was particularly advantageous for testing voltage fluctuation compensation. • It offered a cost-effective and safer alternative to constructing a physical control system. • HIL allowed for the identification and mitigation of potential errors without risking damage to the converter, enabling swift system modifications. Overall, the ERIGrid 2.0 Lab Access programme has proven to be an invaluable asset for advancing smart grid technologies. By enabling rigorous testing and validation in a controlled laboratory environment, it has provided critical support for innovative research, ultimately contributing to the development of more reliable and efficient energy systems.
