Integration of the Transmission System Frequency-based Ancillary Services Markets within EULJUBLJANAC, ANDREA (Avtor) Gubina, Andrej Ferdo (Mentor) Balancing Energy Marketancillary servicesEBGLfrequency restorationmanual Frequency Restoration ReserveThe aim of the Electricity Balancing Guideline (EBGL) is to integrate balancing markets, and as a result, innovative solutions are being developed to realize these goals. These solutions are focused on creating a harmonised European balancing market, which will promote the use of storage providers, demand response and renewable energy sources (RES), that are exponentially entering the energy markets. Procuring balancing energy will move closer to real time, as the balancing process evolves from national to cross-border level. This is important due to increased amount of variable and uncertain RES, which are expected to cause power flow deviations. The balancing markets are becoming integrated through numerous projects being part of the ENTSO-E initiative and the Horizon 2020 framework, that aim to develop platforms for ancillary services’ standard products. These are defined in EBGL and can be exchanged across borders, while focusing on energy efficiency and low carbon technologies. Ancillary services complement energy markets and help ensure the balance in the grid, along with secure operation and quality of energy supply. They are divided into services that take care of frequency deviation processes, like balancing energy (frequency ancillary services), and services for voltage control, like reactive power and voltage support, as well as black start capability and ramping products (non-frequency ancillary services). The Transmission System Operators (TSOs) are procuring balancing energy on the markets with the goal of settling deviations from the nominal frequency in their regulation zones, while other ancillary services are less suitable for open market-based provision. The thesis aims to present innovative solutions for creating a harmonised European balancing market with lower balancing costs, through a made-up scenario of the South-east Europe (SEE) region integration. The scenario will demonstrate the cross-border balancing possibilities for the activation of the optimal bids to satisfy TSOs’ demands in the observed area. To achieve the goal of the thesis, an emphasis is put on frequency ancillary service’s standard product called Manual Frequency Restoration Reserve (mFRR) and the development of the mFRR platform within Horizon2020 project CROSSBOW. The solution presented in CROSSBOW project is a common system market platform for mFRR, which could act as a common European balancing market. Such a market could lower the balancing costs in the observed region by using cross-border balancing energy, hence increasing social welfare within the region. The benefits of mFRR platform are of great importance to the South-East European countries, including Slovenia. Activation of cross-border balancing energy with the help of Activation Optimization Function and Common Merit Order List and improved allocation of real-time Cross-Zonal Capacities ease the future process of harmonizing regulatory frameworks and legislation.20202020-09-28 13:25:01Magistrsko delo/naloga120990sl
