“…The following equations show the calculation of the critical (n-1)-PTDFs and (n-1)-PSDFs of branch b and its critical contingency cc as well as the (n-1)-base case load flow using line outage distribution factors (LODF). The PTDFs, PSDFs and LODFs are calculated as discussed in [17][18][19].…”

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.

“…Apart from existing units, the next ones are under construction or planned to be installed in power systems [11]. According to a publication [12], at the beginning of this century, in Europe, PSTs with total power equal to 5 GW were installed, while in 2030, it is predicted that the total power of PSTs installed will be 50 GW. Therefore, there is still a need to develop these units to achieve the best properties or to attain proposals for new applications.…”

This article was written to present a new solution for a phase-shifting transformer and to show that, in many aspects, the proposed device is more functional and improved when compared to the other currently available phase-shifting structures. The article shows the construction of the new phase-shifting transformer, with longitudinal and transverse voltage regulation. The proposed device’s functionality and available operation states are compared to other existing solutions. Selected steady-state variants of the operation of the proposed transformer were checked based on computer simulations and the laboratory model presented in detail in the article. Convergence between measurements and simulations was achieved. Power flow calculations were also performed in the five-node electrical power system model. In these calculations, two variants of the proposed device’s work were considered and compared with the asymmetric phase shifter. The tests confirmed in the proposed structure, both angle and voltage regulation, enabled maintaining a constant active power flow. The authors show that the proposed solution combines the advantages and functionality of various types of phase shifters while, at the same time, being characterized by a much simpler structure, which results in a two-times-lower cost of the device.
