Evolutionary Particle Swarm Optimization (EPSO), Particle Swarm Optimization (PSO) and Taboo are Heuristic methods based algorithm motivated by Neural Networks. it has been widely used in nonlinear system. This paper is concerned with solving the parameters identification problem for nonlinear dynamic systems through a control with heuristic methods compared with some traditional techniques in the Power System Stabilizer (PSS). Actually, the IEEE model has a low damping ratio performance, with poorly damped electromechanical modes. Our findings have demonstrated a higher the stability performance than traditional methods; the damping ratio is damped for the electromechanical modes for low frequency oscillations when large power systems are interconnected in a Peruvian power plant, the comparison considered three algorithms with Taboo, PSO, EPSO, for the dynamic control in the PSS. La Opt...

In the last years, the knowledge management methodology increased the perspective and deeply analysis in the energy evaluation, with great emphasis in the training of the maintenance teams and early detection of failure modes; these inefficiencies detection is associated to patterns recognition with expert systems. Several energy brands, utilities, universities, and design companies investigated about this problem with limits in the integration between maintenance team knowledge and the degradation of the energy equipment. Therefore, our findings are a new approach of the root cause analysis (RCA) improved with the knowledge management perspective, associated to the failure mode analysis for 164 inverters in photo-voltaic solar plant by using twenty-one failures modes; by incorporate the graph theory called Erdös–Rényi graphs with a quantitative methodology and qualitative evaluation...

The heart of the grid is the power transformer and it is associated to all the electrical chain for distribution, transmission and generation field. Usually the evaluation of the remaining life and condition is based on Furan analysis or dissolved gas analysis (DGA); however, both requires oil samples; in a zero downtime policy, the continuous evaluation requires an additional equipment as online DGA equipment. Due to this limitation, the alternative is the evaluation of the “hot-spot temperature” (HST) in the transformers, with the sensors available in the oil, and winding; but an online evaluation has not been considered in the international standards as IEC 60076-7. So, this paper develops the mathematical model, algorithms and evaluates in a real case study, an optional method to obtain the HST and its impacts in the remaining life. This methodology is applied to three phase tran...

Los métodos tradicionales para la cimentación de líneas eléctricas aéreas tienen problemas en las montañas andinas con la inestabilidad, por lo general debido a la forma del suelo o las fallas de los taludes con sus diferentes variantes, como deslizamientos de tierras, grietas del suelo, terremotos, cortes y rellenos. En esta investigación se ha propuesto una nueva cimentación de tipo micropilote con una mejora de la estabilidad, los hilos robustos que soportan el transporte en zonas de difícil acceso. Con el estudio de caso, se propuso un diseño particular con equipo ligero y una reducción del 24% del costo en comparación con las técnicas tradicionales con un mínimo impacto ambiental. The traditional methods for overhead lines foundations have problems in Andean mountain with instability, it is usually to the ground reformation or slope failures with his different variants...

Una batería de condensadores en serie incluye eventos internos y externos con alta energía a través del circuito en un tiempo transitorio; por lo tanto, una batería de condensadores en serie está equipada con un sofisticado sistema de protección de derivación de Varistor de Óxido Metálico (MOV).

This research article investigates the performance and fault detection capabilities of 35 zig-zag transformers connected to solar power plants in the medium voltage busbar, focusing on “dissolved gas analysis” (DGA) and fault diagnostics. Despite the absence of sudden disconnections, the transformers exhibited evolving failure modes. The study details the protection mechanisms employed, including overcurrent, overvoltage, and me chanical protections, integrated with a master trip system. Revealing significant deviations from normal levels before faults. Elevated hydrogen and methane levels, along with increased acetylene concentrations, indicated severe arcing and overheating, while treated oil samples showed a notable reduction in gas concentrations, underscoring the effectiveness of oil treatment in managing thermal and electrical stresses. This paper highlights the evolution of fa...

In Latin America the renewable energy has increased in 40GW, during the last twenty years; in this perspective countries as Perú, Chile, Brazil, Bolivia and Colombia have extensive desert with the highest irradiance and large field available for this technology. One example is the Atacama Desert and its extension in Chile and Peru; however, it has some challenges as the water availability. Therefore, the clean water availability for industry and agriculture is a problem, only 2.5% of the world’s water is fresh water, this value is decreasing every year for agriculture and industrial process. Our methodology has been applied during 2019 to 2021 with a real case study, one water machine has generated 128,000 L of water per year, >230% of efficiency compared with traditional techniques with the same energy consumption: its contribution with a correlational study of 92.33%.
