This paper presents a comprehensive parametric study of a hybrid islanded microgrid. The study methodology is based on defining various study cases combining structural and operational parameters of the microgrid. Structural parameters include the type of renewable integrated (wind/PV), the battery set point, AC/DC bus connections, weather conditions, and the loading level. Operating parameters include the battery cycle of charging and the diesel generator operation. The defined cases are assessed for a set of performance criteria: renewable share, cost effectiveness, generator life. The study is further enhanced by a sensitivity analysis of the set criteria to the fuel price. The study cases are the reference islanded Chilien microgrid of Desertores, and a north African site in Tunisia. The study is useful for a preliminary design of a microgrid installation.
