Electric distribution systems face many issues, such as power outages, high losses, voltage sags, and low stability, which are caused by the intermittent nature of renewable generation large changes in load demand. To deal with these a system has been designed using both short- long-term energy storage superconducting magnetic (SMES) pumped-hydro (PHES). The aim this paper is to propose metaheu...

The article discusses information on the need to accumulate energy from renewable sources improve their efficiency, as well some examples of integration systems for hydraulic storage and sources, which ensure an increase in reliability volume generation. method determining parameters system a wind power plant, is based balance daily load produced spent storage, presented. This technique, with c...

Pumped storage stations undergo numerous transition processes, which make the pump turbines go through the unstable S-shaped region. The hydraulic transient in S-shaped region has normally been investigated through numerical simulations, while field experiments generally involve high risks and are difficult to perform. In this research, a pumped storage model composed of a piping system, two mo...

Pumped heat electricity storage (PHES) has been recently suggested as a potential solution to the large-scale energy storage problem. PHES requires neither underground caverns as compressed air energy storage (CAES) nor kilometer-sized water reservoirs like pumped hydrostorage and can therefore be constructed anywhere in the world. However, since no large PHES system exists yet, and theoretical...

Remarkably higher expected shares of variable renewable energy sources for electricity generation (RES-Electricity) than those available today will be a great challenge for the European power system. Bulk electricity storage technologies— that is, pumped hydro energy storage—are considered a key component while facing these future challenges. The conducted analysis is based on the modeling resu...
