Estadísticas de producción de electricidad de los países del Sistema de la Integración Centroamericana (SICA): datos preliminares a 2015

En este documento se presentan, de manera preliminar, cuadros regionales y nacionales con datos estadísticos de la producción de energía eléctrica de los ocho países que conforman el Sistema de la Integración Centroamericana (SICA): Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panamá, Belice y la República Dominicana. Los primeros seis países han sido agrupados bajo el Sistema de Interconexión Eléctrica de los Países de Centroamérica (SIEPAC), que corresponde al primer mercado eléctrico regional que ha sido constituido en el continente americano. Las referencias a México corresponden a los intercambios y ventas de energía eléctrica que se hacen desde ese país a Guatemala y marginalmente al resto de países del SIEPAC. También se refieren a las ventas de energía eléctrica de México a Belice. El documento contiene información actualizada a 2015 sobre la capacidad instalada y producción de energía eléctrica en cada uno de los países, desglosada por tecnología y resúmenes de operación de los mercados mayoristas y de las transacciones regionales de electricidad. La sección de hechos relevantes describe las principales inversiones realizadas en la región con especial atención en las nuevas plantas generadoras de electricidad, la producción de electricidad por país y fuentes primarias, así como la evolución del mercado eléctrico regional.

A novel grid computing approach for probabilistic small signal analysis

Grid computing is an advanced technique for collaboratively solving complicated scientific problems using geographically and organisational dispersed computational, data storage and other recourses. Application of grid computing could provide significant benefits to all aspects of power system that involves using computers. Based on our previous research, this paper presents a novel grid computing approach for probabilistic small signal stability (PSSS) analysis in electric power systems with uncertainties. A prototype computing grid is successfully implemented in our research lab to carry out PSSS analysis on two benchmark systems. Comparing to traditional computing techniques, the gird computing has given better performances for PSSS analysis in terms of computing capacity, speed, accuracy and stability. In addition, a computing grid framework for power system analysis has been proposed based on the recent study.

Sustainable rural micro-enterprises through co- and tri-generation:review of concepts

Biomass production, conversion and utilization can be done locally with value addition to small farmers. However, new technical inputs are needed for profitable exploitation of biomass within the constraints related to land, water and skill availability and to provide higher quality of energy needed for rural industries. Trigeneration, which is generating energy simultaneously in three forms (electric power, heat for processing and refrigeration), helps in fully utilizing the stored energy in biomass and would be most appropriate for micro enterprises. This paper presents concepts in terms of trigeneration systems feasible for rural areas.

Direct current ripple compensation for multi-phase fault-tolerant machines

A second-harmonic direct current (DC) ripple compensation technique is presented for a multi-phase, fault-tolerant, permanent magnet machine. The analysis has been undertaken in a general manner for any pair of phases in operation with the remaining phases inactive. The compensation technique determines the required alternating currents in the machine to eliminate the second-harmonic DC-link current, while at the same time minimising the total rms current in the windings. An additional benefit of the compensation technique is a reduction in the magnitude of the electromagnetic torque ripple. Practical results are included from a 70 kW, five-phase generator system to validate the analysis and illustrate the performance of the compensation technique.
