RT Journal Article T1 Improving the Reliability of an Electric Power System by Biomass-Fueled Gas Engine A1 Clavijo Camacho, Jesús A1 Ruiz Rodríguez, Francisco Javier A1 Clavijo Camacho, Jesús AB This paper shows a practice to raise the reliability of an electric power system by theinstallation of distributed generation, taking gasified biomass as fuel. To calculate the reliability index,a probabilistic load flow was used. This index is determined as the fault probability of the system.The resolution of this probabilistic load flow combines the method of cumulants and Gram–Charlierexpansion. To achieve the reliability index, simulating a number of contingencies is required; thegreater the number of simulated contingencies, the higher the accuracy of the index obtained. Thisprobabilistic technique uses the random variables as starting information, so the two generatorsand loads are simulated as random variables. The generators of this distributed generation arebiomass-fueled gas engines, commonly found in Spain. The simulations carried out on the IEEE14-bus Test System, including three biomass generators, show that the inclusion of this type ofgeneration improves the overall reliability indices of the electrical system PB MDPI SN 1996-1073 (electrónico) YR 2022 FD 2022-11 LK https://hdl.handle.net/10272/21385 UL https://hdl.handle.net/10272/21385 LA eng NO Clavijo-Camacho, J., & Ruiz-Rodriguez, F.
