Jukić DK, Kugi A, Kemmetmüller W. Optimal Operation of Pumped Storage Power Plants with Fixed- and Variable-Speed Generators in Multiple Electricity Markets Considering Overload Operation. Journal of Energy Storage. 2024 Apr 12;88(2024):1-13. 111601
Highlights A strategy for integrated operation of wind and pumped-storage plants is proposed. Participation of both plants in energy and ancillary service markets is modeled. The uncertainty of wind production is modeled by a novel probabilistic function. The proposed strategy is tested on a real case in the Spanish electricity market.

Description of Outcome Technical power losses and climate vulnerability of the electricity network in Nuku''alofa reduced. Progress Toward Outcome Implementation Progress
The sudden breakdowns of the power generation facilities caused a serious concern about the stable operation of the power system. However, since electricity system in South Korea is not connected to neighboring country, it is necessary to devise methods to counteract emergency such as unexpected failure of a power plant or …
Thus, some papers consider combinational operation of wind energy resources with other energy resources. Ref. [12] discusses a strategy for offering and operating a combination of wind and hydro-generation resources, which results in an increase in their joint revenues. In [13], [14], joint operation of wind and pumped-storage …
This paper presents a mixed-integer model for the hourly energy and reserve scheduling of a price-taker and closed-loop pumped-storage hydropower plant operating in hydraulic short-circuit mode. The plant participates in the spot market and in the secondary regulation reserve market, taking into account the regulation energy due to the …
2.2. Case study The data set used to illustrate the proposed methodology consists of the hourly wind power production of a wind farm located in the northwest of Spain during a two year period. Hourly wind power predictions for up to H = 35 h ahead are available for this period.h ahead are available for this period.
This paper is devoted to the operation of large-scale photovoltaic and pumped storage power plants under market conditions as well as the problem of taxation. We are determining an option that is acceptable to both the transmission network operator and the power plant.An optimization problem has been posed and solved, including the …
The integration of flywheels or supercapacitors in existing pumped-storage plants is economical, little intrusive, environmentally friendly, and yields an energy storage plant with all necessary features for the integration of renewable energy: fast active and reactive power response, large energy storage capacity and an extraordinary ...

Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.
The Nant de Drance pumped storage power plant is located 600 m below ground in a cavern between the Emosson and Vieux Emosson reservoirs in the canton of Valais. The power plant works like a gigantic battery: during demand peaks, Nant de Drance produces electricity. If, on the other hand, electricity production from non-controllable renewable ...
German power utility EnBW says its new pumped hydro storage project will require an investment of €280 million ($304.9 million). It is scheduled for completion by the end of 2027.
A full-size converter-fed synchronous machine (CFSM) technology is emerging as the most flexible system for pumped storage plants for efficient operation in a wide range of water flows, which is not the case in existing power plants with fixed-speed synchronous machines. This article presents steady-state control strategies to execute …
