Abstract (EN): The decarbonization of the electrical system (ES) is an inevitable truth. Thus, many economies that share concerns about climate change, invest in renewable sources to help contain the global warming. However, the massive integration of these renewable sources, which brings more intermittency and volatility, together with the natural variation of consumption, pose greater challenges that should be mitigated with adequate tools, as offered by a liberalized and organized electrical market. To help cost reduction in a market environment, the coordination between different Transmission System Operators (TSOs) is of utmost importance. The objective of this work is to provide a framework analysis for the sharing of ancillary services (AS) in the context of the Iberian ES, in particular a techno-economic analysis for the secondary reserve (SR) control. The SR control is fundamental to correct load variations and help stabilize the ES where the TSOs are inserted. To this end, the main goal is to control the regional imbalance of the Iberian Peninsula, in a coordinated way, with a minimization of costs. The results show that it is possible to generate synergies in 45% of the market periods and an average profit of 3.4 M(sic) per year. There are enough reasons to implement the coordination procedures between the Iberian TSOs in order to manage their own SRs in a profitable and reliable way, and to become more competitive when exchanging with other European TSOs.
