“…Focusing on practical computer simulations in research, Rezghi and Riasi [30] provide a numerical simulation to study the interaction effect of the hydraulic transient conditions of selected pump-turbine units in PSH taking into account the 'S-shaped' instability region. Savchyn and Vaskovets (Ukraine) [31] study the local geodynamics of the location of Dniester's PSH. The aim of their work is to find out about the recent local geodynamic processes on the mentioned place which arise because of the additional man-caused load during the construction of hydrotechnical structures.…”

The increase in the share of renewable energy sources (RES) leads to a growing need for sources or systems/actions to stabilize the national energy grid. Such stabilizing actions include market tools, such as prices and demand-side response (DSR) tools, as well as flexible energy sources (e.g., gas). In addition, energy storage, where pumped storage hydroelectricity (PSH) accounts for 90% of global storage capacity, plays an important role. Therefore, the authors presented a detailed analysis of PSH in the context of the dynamic growth of installed capacity in renewable energy sources. They analyzed the economic viability of this type of power plant, with a particular emphasis on operational costs, energy production, and revenue. The Młoty case study and market data, including historical data on various PSH, were presented and analyzed. This study uses copulas, simulation, and statistical analysis. The authors proved that market prices and arbitrage actions alone are not sufficient to achieve profitability of the investment; however, additional benefits, such as fees for available power, enable the achievement of economic profitability. The reason for this is the fact that one of the main goals of PSH is to serve as a power reserve. In addition, this paper presents the analysis of the utilization of existing PSH in the form of full pumping and energy generation cycles (charging and discharging storage).

“…The study of geodynamic processes and areas of both Ukraine [Tretyak et al, 2015] and the European continent [Tretyak & Vovk, 2016] in general is a relevant aspect of geodetic research, as well as establishing the magnitude of the annual change as horizontal [Tretyak & Vovk, 2014;Vovk, 2015] and vertical [Tretyak & Romaniuk, 2014;Tretyak & Romaniuk, 2018] movements of the earth's crust associated with age-related geodynamic processes, especially in man-made areas [Zayats et al, 2017;Mordvinov et al, 2018;Savchyn & Vaskovets, 2018;Savchyn & Pronyshyn, 2020]. The results of such geodetic measurements give information about the movement only at certain points on the earth's surface, and not for the entire earth's crust.…”

Purpose. The purpose of this work is obtaining connections between the Baltic and European height systems based on the I class leveling between the Ukrainian and Polish control points of the base vertical networks and construction of the quasigeoid surface on the border area. Method. Full integration of the hight system of Ukraine into the European vertical reference system (EVRS) consists of two stages: modernization of the height network of Ukraine through its integration into the United European leveling network UELN; construction and use as a regional vertical date the model of high-precision quasigeoid, which will be consistent with the European geoid EGG2015. The analysis of methods of high-precision leveling in Ukraine and Poland, and also the analysis of methods of construction of quasigeoid models in these countries is performed. Results. For integrating the Ukrainian hight system into the UELN/EVRS2000 system, the Ukrainian side performed I class geometric leveling along two lines: Lviv - Shehyni - Przemysl and Kovel - Yagodyn - Chelm with total length of 196 km. The root mean square systematic error on both lines of leveling was s<0.01 mm/km. In turn, the mean square random error along the line Lviv - Shehyni - Przemysl is h=0.29 mm/km, and along the line Kovel - Yagodyn - Chelm is h=0.27 mm/km. For double control on the cross-border part, the Polish side performed high-precision leveling with a length of 33 km. The differences between the Ukrainian and Polish leveling in all sections are within the tolerance. The analysis of influence of geodynamic phenomena on control of high-precision leveling is carried out. GNSS-leveling was performed on all fundamental and ground benchmarks, as well as horizontal marks. These measurements were used to build a quasigeoid model for the border area of Ukraine. The MSE of the obtained quasigeoid model is about 2 cm, which corresponds to the accuracy of the input information. Scientific novelty and practical significance. The connection of the Ukrainian and European height systems will ensure Ukraine’s integration into the European economic system, participation in international research of global ecological and geodynamic processes, study of the Earth’s shape and gravitational field and mapping of Ukraine using navigational and remote-sensing satellite technologies. Calculation of a high-precision model of a quasigeoid on the Ukraine area in relation to the European height system, agreed with the European geoid EGG2015, will allow to obtain gravity-dependent heights using modern satellite technologies.

“…Dnister Hydro Power Complex is under continuous monitoring: GNSS observation network is differentiated [Savchyn and Vaskovets, 2018], the relationship between construction stages and seismicity of the region is determined [Savchyn and Pronyshyn, 2020], kinematics of HPP-No. 1 dam are differentiated [Tretyak et al, 2021b] and the interrelation of altitude displacements of the GNSS sites due to non-tidal atmospheric loads are identified [Tretyak et al, 2021a].…”

The article presents the aspects of historical development of monitoring of Tereble-Ritska hydroelectric power station (HPP), which led to the need of establishing an automated system of geodetic monitoring (ASGM) of deformations of the water pipeline and other structures. Since 2018, the system has been automated and the instrumental part continues to be expanded. Thus, as of 2022, the instrumental part of ASGM includes 3 main components, namely: linear-angular measurements with the determination of meteorological parameters, satellite GNSS measurements, and piezometric measurements. This article presents the results of ASGM work in order to monitor deformations. There are also some advantages of using ASGM in comparison with classical measurements, which first of all allow determining of coordinates in real-time and increase the accuracy of spatial deformation detection to 2 mm (horizontal) and 3 mm (height) on an area of 2 km2. It is also possible to inform the maintenance services of the monitored object when the received deformation exceeds the established limits. According to the results of the time series of linear-angular measurements, it can be stated that the pipeline undergoes seasonal displacements which are manifested in the horizontal displacement of supports towards the HPP building from winter to summer, and vice versa from summer to winter. To date, the amount of special data for the aggregate analysis of linear-angular measurements with the determination of meteorological parameters, GNSS measurements and piezometric measurements is insufficient. As data accumulates, it will be important to establish relationships between these parameters.
