“…Nevertheless, these focus on Germany (Winkler et al 2016;Singh et al 2015) or Europe as a whole (Fürsch et al 2013;Majchrzak et al 2013;Schaber et al 2012a;. The grid related literature in Poland examined most often possibilities of phase-shifting transformers (Korab & Owczarek 2016;Kocot et al 2013).…”

Influence of renewable energy sources on transmission networks in Central Europe

This paper focuses on the influence of increased wind and solar power production on the transmission networks in Central Europe. To assess the exact impact on the transmission grid, the direct current load flow model ELMOD is employed. Two development scenarios for the year 2025 are evaluated on the basis of four representative weeks. The first scenario focuses on the effect of Energiewende on the transmission networks, the second one drops out nuclear phase-out and thus assesses isolated effect of increased feed-in. The results indicate that higher feeding of solar and wind power increases the exchange balance and total transport of electricity between transmission system operator areas as well as the average load of lines and volatility of flows. Solar power is identified as a key contributor to the volatility increase; wind power is identified as a key loop-flow contributor. Eventually, it is concluded that German nuclear phase-out does not significantly exacerbate mentioned problems.

“…Additionally, as shown by Mekonnen et al [13], present flow-based cost allocation methods are highly sensitive to the TSO power flow controlling resources such as phase-shifting transformers, and may create incentives for the TSOs to use such so-called ‘non-costly’ remedial actions inefficiently. References [14,15] showcase the importance of coordinating the operation of TSO power flow controlling resources at the multi-area level to efficiently guarantee the interconnected system security. It follows that an incentive structure also recognizing the positive/negative impact of these ‘non-costly’ TSO remedial actions used to manage security by taking advantage of grid flexibility 2 is necessary to maximize the value of multi-TSO coordination for multi-area power system security management.…”

This paper advocates for a progressive rethinking of the day-ahead/intra-day power system security management practice in the low-carbon energy transition era. As a starting point, the need for coordination between multi-area transmission system operators in order to efficiently exploit the value of grid flexibility towards operating the low-carbon, multi-area power system securely and economically is emphasized. On this basis, the core proposal of this paper is the adoption of a new approach to day-ahead/intra-day multi-area power system security management, inspired by the principles of cooperative game theory. The proposed approach relies on counterfactual analysis to evaluate the (positive and/or negative) impact of each distinctive control area to the common security of the multi-area system, thus providing clear economic incentives to achieve the required coordination. This proposal is not a marginal approach and notably facilitates the integration of more detailed physical modelling (including the non-convexities of the power system) in the inter-TSO settlement of the multi-area interconnected system security management cost. The proposed framework allows some level of subsidiarity and the definition of hedging products to cover ex-post costs. Further from the blueprint of the proposed approach, the paper presents a demonstrative implementation in the context of static N-1 security management and discusses prominent research and development pathways in order to progressively put such vision into practice. This article is part of the theme issue ‘The mathematics of energy systems’.

“…The coordination of phase shifting transformers (PST) has been discussed so far regarding the effect on the total transfer capacity between two areas [5], the capabilities of equalizing the loading cross border interconnectors [6,7] in an multi bidding zone network. These studies strongly indicate the need for a coordination between PSTs to avoid additional congestions caused by loop flows.…”

In this paper, the effects of coordinated operation management of embedded HVDC links and phase shifting transformers on the optimal redispatch costs and volumes are examined. The underlying optimization problem, including these power flow controlling devices, is formulated for linear optimization using DC load flow equations. The evaluation is based on the results of a year-round simulation of the expected energy market and network situation of the ENTSO-E region of the year 2025. The results highlight the need for coordinated operation management of PFCs since uncoordinated operation management increases the accruing redispatch costs.
