This paper proposes a methodology for identifying and assessing the impact of distributed generation interconnection on distribution systems using Monte Carlo techniques.
This methodology consists of two analysis schemes: a technical analysis, which evaluates the reliability conditions of the distribution system; on the other hand, an economic analysis that evaluates the financial impacts on the electric utility and its customers, according to the system reliability level.
The proposed methodology was applied to an IEEE test distribution system, considering different operation schemes for the distributed generation interconnection. The application of each one of these schemes provided significant improvements regarding the reliability and important economic benefits for the electric utility. However, such schemes resulted in negative profitability levels for certain customers, therefore, regulatory measures and bilateral contracts were proposed which would provide a solution for this kind of problem.
Este trabajo propone una metodología para identificar y evaluar los impactos de interconectar generación en los sistemas de distribución, utilizando técnicas de Monte Carlo. Dicha metodología está compuesta por dos esquemas de análisis: uno técnico que evalúa las condiciones de calidad del servicio con las que cuenta el sistema de distribución, y por otro lado, un análisis económico que evalúa el impacto financiero sobre el operador de red y sus clientes, de acuerdo con el nivel de calidad del servicio del sistema. La metodología propuesta fue aplicada a un sistema de distribución de prueba IEEE, considerando diferentes esquemas de operación para la interconexión de generación distribuida. La aplicación de cada uno de estos esquemas, trajo consigo mejoras significativas en la calidad del servicio suministrado e importantes beneficios económicos para el operador de red. Sin embargo, dichos esquemas implicaron niveles de rentabilidad negativa para ciertos clientes, por lo tanto, se propusieron medidas de carácter regulatorio y contratos bilaterales, que permitirían dar solución a este tipo de problemas.
