Escuela Ambiental, Facultad de Ingeniería, Universidad de Antioquia UdeA, Medellín. Colombia Abstract In this study, the evaluation of the rotor performance of a gravitational vortex turbine (TVG) for its application in distributed power generation is presented. A numerical analysis was carried out on a specific configuration of a TVG, characterized by its spiral inlet and conical discharge. The dimensions of the discharge chamber and the inlet channel, such as the inlet channel width (w), length (L), and height (h), the discharge cone height (H) and diameter (d), and the envelope angle (γ) were determined through previous optimization studies documented in the literature. These dimensions are related to the basin diameter (D), which was set at 500 mm for this study.

State University of Rio de Janeiro (UERJ), Rio de Janeiro, Brazil. 2. Pontifical Catholic University of Rio de Janeiro (PUC-Rio). Brazil 3. IBMEC, Rio de Janeiro. Brazil Abstract Over the last twenty years, Brazil has experienced significant changes in its electric energy matrix, notably with the expansion of wind and solar energy sources. In the early 2000s, hydroelectric plants with a capacity of 70 gigawatts (GW) were responsible for generating 90% of the country's electricity, while solar and wind sources contributed merely 1%. Today, the scenario has evolved, with wind and solar energy comprising approximately 25% of the national generation, indicating a departure from the previous hydro-dominated matrix...READ MORE |

Comparison between FLL and PLL in frequency estimation to supply distributed virtual inertia Erland Novoa(1), Julio C. Tafur(2), Damian Sal y Rosas(3) 1. Department of Engineering - Mechatronic Engineering Master Degree Program Pontificia Universidad Católica del Perú 2. Department of Engineering -Control and Automation Engineering Master Degree Program Pontificia Universidad Católica del Perú 3. LAAS-CNRS, University of Toulouse. France Abstract To connect renewable energy sources (e.g. solar or wind) on the grid, an inverter or electronic converter is used. However, a traditional inverter has no inertia in the face of frequency changes. Unlike the inertia of the rotor of a synchronous generator. Frequency variations are a product of the imbalance between the energy generated and the grid loads. If the frequency is too far from its nominal value or if the rate of change of frequency (RoCoF) is high, it can affect the synchronism of the generators that feed the grid...READ MORE
