Special Issue Information

Dear Colleagues,

Pumped-storage hydropower (PSH) is the flexible giant among the current energy storage technologies. Established in the early days of electrification, these forever-assests have been balancing all types of power production and adapting successfully to several power market transitions. To achieve decarbonization of the energy system to mitigate climate catastrophes, this long-lasting and multipurpose technology allows us to store both water and energy, as well as providing capacity and inertia for grid balancing. Pumped-storage hydropower plants have been continuously developed and adapted to new challenges and demands over time. This research field covers multiple disciplines and demands for interaction and exchange of knowledge and experience.

This Special Issue aims to highlight recent achievements in the development of pumped-storage hydropower, especially with regards to its flexibility with several potential applications in ongoing energy transition. The scope is to collect and present new design concepts, structural details, and hydraulic machinery insights, but also to highlight the important aspects of energy economics and concepts for upgrading and retrofitting existing hydropower plants and pumped-storage plants. Review papers for special solutions or experiences from long-term operation from existing pumped storage plants are welcome. Papers may include results from physical scale models, numerical investigations, field measurements and operational experience. Contributions focusing on environmental issues and sector coupling for multipurpose application of pumped storage are welcome. Additional requested topics include power grid balancing, digital twins, and predictive maintenance. We look forward to recieving your interesting contributions on the increasingly important topic of pumped storage hydropower.

Suitable and accurate flow measurement in pumped storage hydropower plants (PSP) is a challenging task due to the entirely different hydraulic behaviour of the penstock. This study presents a novel approach to choosing a suitable flow measurement method and position. The focus is on the flow measurement in a specific short penstock of the largest peak-load hydropower plant, Orlík, after its transformation to a PSP. Our approach is based on three main pillars: numerical modelling of fluid flow (ANSYS CFX), standards, and scientific literature. First, the steady-state numerical model output for the current state is compared to historical measurements of point velocities using current meters and measured hydraulic losses in the penstock. Subsequently, for the planned conversion to the reversible Francis turbine, including shape modifications of the flow paths, a steady numerical simulation of the flow in the penstock was performed in both turbine and pump modes. By analysing the resulting pressure and velocity fields and comparing them to standards and scientific literature, the values of the uncertainty in the flow measurement were calculated. The outcome is a straightforward evaluation and comparison of three main flow measurement methods: current meter, pressure–time, and ultrasonic transit time. Full article

Energy security is one of the main factors in the development and diffusion of microgrid applications. In networks operating without storage, the operation of their systems is greatly affected by sudden load demand and intermittent generation fluctuations. The main purposes of using energy storage systems in microgrids are stabilizing the intermittent generation of renewable energy sources locally, to ensure that energy production matches energy demands, participating in the frequency regulation process, maintaining the energy balance between generation and demand in renewable energy microgrids, and increasing energy reliability. This study investigates the frequency and power balance of an isolated microgrid system, by including storage systems (battery and pump-hydro). Realistic data for wind and solar sources are used for the optimal tuning of the proportional-integral controller, using the integral of the absolute error criterion multiplied by time, with a Quasi-Newton method. Simulation studies have been carried out, to investigate the performance of the microgrid system, by including the hydroelectric power plant system with pump storage for 24 h, under various operating conditions. The results reveal that by including the storage units in the system, it exhibits a more consistent and smooth dynamic performance, using renewable energy efficiently. Full article
