This study deals with the optimal sizing of an off-grid hybrid systems with multi generation set architectures that could be used to satisfy the energy load requirements of a typical rural community. In order to assess the techno-economic feasibility and to obtain the optimal sizing of components, the economic performances of each hybrid system are compared to those achievable with a traditional stand-alone diesel supply system and with the alternative possibility of a grid extension. The designed hybrid system could include renewable sources as a photovoltaic plant, a wind turbine, as well as an energy storage system and a diesel generator. In addition, a smart energy management system able to achieve the maximum benefits from the combined operation of the different energy resources is taken into account. Different hybrid system designs are considered and, for each potential configuration, the technical aspects, costs and environmental impact are evaluated, to identify the optimal energy supply option. Sensitivity analysis are implemented on parameters typically affected by uncertainty, with the aim of assess the impact of their variation on the entire system performances.

Abstract

This study deals with the optimal sizing of an off-grid hybrid systems with multi generation set architectures that could be used to satisfy the energy load requirements of a typical rural community. In order to assess the techno-economic feasibility and to obtain the optimal sizing of components, the economic performances of each hybrid system are compared to those achievable with a traditional stand-alone diesel supply system and with the alternative possibility of a grid extension. The designed hybrid system could include renewable sources as a photovoltaic plant, a wind turbine, as well as an energy storage system and a diesel generator. In addition, a smart energy management system able to achieve the maximum benefits from the combined operation of the different energy resources is taken into account. Different hybrid system designs are considered and, for each potential configuration, the technical aspects, costs and environmental impact are evaluated, to identify the optimal energy supply option. Sensitivity analysis are implemented on parameters typically affected by uncertainty, with the aim of assess the impact of their variation on the entire system performances.
