Tiivistelmä
Global developments in renewable energy and energy efficiency of the power consumption present challenges to maintain the frequency stability of the electricity grids. The objective of the research is to investigate how the current and potential future install base of battery systems could be used to provide secondary grid support applications. The research focuses on stationary battery applications, and more specifically, uninterruptible power supply (UPS), telecommunications, and grid storage systems.
This doctoral dissertation is based on articles published in scientific journals and international conferences. The results presented in the articles and the dissertation show that the existing battery systems can be used to provide grid services. The conducted research focuses on specific types of services that these systems can provide and their economic and technical feasibility. In addition, several critical boundary conditions and potential limitations on participation are identified and analyzed.
The investigations leading to the conclusions include preliminary studies and simulations and were further confirmed by several successful market pilots performed with Nordic transmission system operators. In these pilots, data center UPS systems were used to provide primary frequency reserve and fast frequency reserve services.
Another main objective of the research was to develop business models where battery system investments could be made with significantly reduced costs by using the existing data center infrastructure or battery systems could be sold as a service for distribution system operators. The business models are presented in the dissertation and have resulted in several pilot projects.
