In 2021, Honduras'' energy mix was led by oil, constituting 52.3% of the total energy supply, followed by biofuels and waste at 33.7%. Modern renewables, which exclude traditional biomass practices like burning wood or agricultural residues, accounted for 13.7%, while coal made up just 0.3%. Currently, 33 percent (502 MW) of the installed capacity of the national interc

Pumped-storage hydroelectric plants are an alternative to adapting the energy generation regimen to that of the demand, especially considering that the generation of intermittent clean energy provided by solar and wind power will cause greater differences between these two regimes. In this research, an optimal operation policy is determined
The pumped hydro energy storage (PHES) is a well-established and commercially-acceptable technology for utility-scale electricity storage and has been used since as early as the 1890s. Hydro power is not only a renewable and sustainable energy source, but its flexibility and storage capacity also make it possible to improve grid
Insular power systems are a special case of infrastructure for power production due to their particular land morphology with extensive hills and ridges. For a higher renewable energy share in the power production, a dedicated design according to local constraints is required. The high wind and solar resources of such cases can be

In Section 2.3, the coordinated operation of wind and pumped-storage power plants is discussed, from the perspective of both the TSO and the PSHP operator. Section 2.4 deals with the operation of PSHPs capable to provide load-frequency control in pumping, or consumption mode, by means of variable speed or hydraulic short-circuit
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 launch of the Nant de Drance plant, which sits 600m below ground in a cavern between the Emosson and Vieux Emosson reservoirs, marks the conclusion of 14 years of construction.
The aim of the present paper is to investigate the use of the site "Potamon" Dam in the Prefecture of Rethymnon, Crete island, Greece, as a "virtual" renewable electricity supply of a pumped storage
The present work aims to study an alternative means of energy storage, a pumped storage subsystem, in stand-alone desalination plants, and to investigate its role on the operation of the whole scheme. Pumped storage in hybrid wind-hydro power production plants has been studied applying numerical design optimization
It has just connected the first of four 220-MW turbines at the Gouvães hydroelectric power plant, which will provide 880MW of pumped hydro energy storage (PHES) alongside two run-of-river hydroelectric plants which bring the complex''s total hydoelectric power to 1,158MW. Gouvães and one other will go online in mid-2022 while
The aim of the present paper is to investigate the use of the site "Potamon" Dam in the Prefecture of Rethymnon, Crete island, Greece, as a "virtual" renewable electricity supply of a pumped storage plant (PSP) in order to save and exploit the maximum possible part of the rejected wind energy of the autonomous power system of the Crete island.

I. INTRODUCTION Pumped-hydro energy storage (PHES) is the principal large-scale energy storage technology in use in the current power systems [1], [2] and constitutes a key enabler for the
When prices are low enough, the plant begins the operation as a pump, until it is full or obtains the optimum stored energy (from hour 2 at the end of hour 7). After that, the storage plant waits for higher prices. The hydro-pump plant sells the energy during the periods of highest prices.
The gross head of pumped storage plants ranges from 30 to almost 400 meters. Hydroelectric turbines of the reversible type convert the kinetic energy into electricity, or vice-versa. Water levels are controlled by weirs, and the water flow via the spillway and by valves integrated into the penstock.
A sketch of the hybrid power plant under consideration is given in Fig. 1 a. The plant consists of a wind farm and a pumped-storage unit, which absorbs almost the entire wind production to elevate water from the reference level of a lower reservoir and store it to an upper reservoir of equal capacity, at +430 m static head.A number of wind
