Conservation Letters, Volume 18, Issue 1, January/February 2025.ABSTRACT Conservation investments do not operate within a zero‐sum paradigm, but instead provide opportunities for co‐benefits across sustainable development and conservation goals. Recognizing the interconnectedness of conservation efforts within socioenvironmental systems can amplify support for conservation actions, ultimately creating additional co‐

Torque and Power Testing of the Pelton Turbine
Jurnal Teknik Mesin, 2021 Energy sources that can be renewed in Indonesia according to Asean energy sources, one of which is microhydro that uses water as a source of energy from a turbine. The potential energy of water is converted into kinetic energy in the nozzles. The water coming out of the nozzle that has a high speed hits the turbine blade.

International Journal of Energy Research, Volume 2025, Issue 1, 2025.This paper proposes innovative control schemes for Pelton turbines to improve frequency regulation in isolated power systems with high penetration of variable renewable energy sources (vRESs). Traditionally, Pelton turbine deflectors are used as safety mechanisms; however, this study explores their potential for continuous frequency regulation ...

Numerical prediction of Pelton turbine efficiency
IOP Conference Series: Earth and Environmental Science, 2010 This paper presents a numerical analysis of flow in a 2 jet Pelton turbine with horizontal axis. The analysis was done for the model at several operating points in different operating regimes. The results were compared to the results of a test of the model. Analysis was performed using ANSYS CFX-12.1 computer code.

A dam management problem with energy production as an optimal switching problem
Applied Stochastic Models in Business and Industry, Volume 40, Issue 6, Page 1596-1611, November/December 2024.Abstract We consider an optimal stochastic control problem for a dam. Electrical power production is operating under an uncertain setting for electricity market prices and water level which has to be kept under control. Indeed, the water level inside the basin cannot exceed a certain threshold for safety reasons, and at the same time cannot decrease ...
