- W2888950611 abstract "espanolEl objetivo del trabajo fue programar el mantenimiento preventivo de las unidades generadoras de un sistema de potencia con un modelo de optimizacion que minimiza el costo de operacion y mantenimiento. Para modelar el costo de operacion de las unidades se utiliza una funcion cuadratica y para el mantenimiento una funcion lineal, ambas dependen de la demanda del sistema. Las propuestas de programacion y la combinatoria que garantiza el menor costo de operacion en el predespacho economico de las unidades son generadas con un algoritmo de optimizacion por enjambre de particulas. La funcion multi-variable no-lineal con restricciones que resulta como objetivo se optimiza mediante un metodo de programacion cuadratica secuencial Cuasi-Newton que aproxima la Hessiana en cada iteracion por diferencias finitas. El trabajo muestra como el margen de reserva del sistema afecta la programacion del mantenimiento preventivo de un sistema de potencia con presencia de fuentes no convencionales de energia EnglishThe objective of the work was to program the generator preventive maintenance of a power system with an optimization model that minimizes the cost of operation and maintenance. A quadratic function is used to model the operation cost of the units, and for the maintenance a linear function, both depend on the demand of the system. The programming proposals and combinatorial that guarantee the lowest cost of operation in the unit commitment are generated with a particle swarm optimization algorithm. The nonlinear multi-variable function with constrained that results in the modeling is optimized by a Quasi-Newton sequential quadratic programming method that approximates the Hessian in each iteration by finite differences. The work shows how the reserve margin affects the scheduling of preventive maintenance of a power system with the presence of unconventional sources of energy" @default.
