“…The potential beneficial effect of GSKs on the size of the FB domain is highlighted with the remark that for the welfare evaluation redispatch cost have to be included in the analysis Weinhold ( 2021 Present a framework to include security constraints efficiently into FBMC in large power systems.

“…Wyrwoll et al (2018) cover the Core region but neglect security constraints. Wyrwoll et al (2019) analyses the affect of base case methods in a focus region covering Germany and the electric neighbours. To the best of the author's knowledge, no framework has been presented, which is capable of covering FBMC with an hourly resolution and accounting for security constraints, with a nodal representation of the Core K…”

Impact of Flow Based Market Coupling on the European Electricity Markets

Flow Based Market Coupling is the target model for determining exchange capacities in the internal European Electricity Market. It has been in operation in Central Western Europe since 2015 and is scheduled to be extended to the wider Core region in the near future. Exchange capacities have a significant impact on market prices, exchanges and the energy mix, thus also determining the CO$${}_{2}$$ 2 footprint of electricity generation in the system. Stakeholders therefore need to develop an understanding for the impact of Flow Based Market Coupling and the parameter choice, like the minimum exchange capacities introduced in 2020, on the market outcome. This article presents a framework to model Flow Based Market Coupling and analyse the impact of different levels of regulatory induced minimum trading capacities as well as the effect of the extension towards the Core region. Electricity prices, exchange positions and the number and nature of binding constraints in the market results under different market coupling scenarios are investigated. The results show that increased level of minimum trading capacities in CWE market coupling decrease the German net export position by up to 7 TW h or 23%, while French exports increase by up to 10 TW h or 9%. The different transfer capacity in the scenarios induce a price difference of up to 13%. Increased exchange capacities allow for more base load generation with the corresponding effects for the CO$${}_{2}$$ 2 emissions of the system. The nature of coupling constraints is highly dynamic and dependent on the system state, which makes the suitability of static NTC values in energy system scenarios questionable.

“…To date, studies on FBMC have not considered FRMs in terms of an uncertainty model and risk-threshold, but rather employ fixed security margins that are applied uniformly to all CNEs, see e.g., Schönheit et al (2021bSchönheit et al ( , 2020a; Wyrwoll et al (2019). While such simplifications may be motivated by a lack of historical data to simulate the FRM computation process prescribed by regulation, ignoring the specific impact of real-time control actions caused by intermittent renewable injections may obstruct a clear assessment of the effectiveness of FBMC in high RES systems.…”

The effective allocation of cross-border trading capacities is one of the central challenges in implementation of a pan-European internal energy market. flow-based market coupling (FBMC) has shown promising results for to achieve better price convergence between market areas, while, at the same time, improving congestion management effectiveness by explicitly internalizing power flows on critical network elements in the capacity allocation routine. However, the question of FBMC effectiveness for a future power system with a very high share of intermittent renewable generation is often overlooked in the current literature. This paper provides a comprehensive summary on FBMC modeling assumptions, discusses implications of external policy considerations and explicitly discusses the impact of high-shares of intermittent generation on the effectiveness of FBMC as a method of capacity allocation and congestion management in zonal electricity markets. We propose to use an RES uncertainty model and probabilistic security margins on the FBMC parameterization to effectively assess the impact of forecast errors in renewable dominant power systems. Numerical experiments on the wellstudied IEEE 118 bus test system demonstrate the mechanics of the studied FBMC simulation. Our data and implementation are published through the open-source Power Market Tool (POMATO).
