Context:

The increase in rural electrification projects has led to the emergence of technologies that allow operating local distribution networks such as isolated microgrids. However, the successful implementation of these isolated microgrids requires that their planning, operation, monitoring, and control consider a framework that allows maintaining technical, economic, and environmental sustainability over an extended time horizon. Therefore, this paper proposes a model that allows identifying the main technical, economic, regulatory, and environmental variables that should be considered for the successful planning of Colombian rural electrification solutions.

Methodology:

This paper proposes the use of System Dynamics to create a model that allows describing the causal relationships between the different variables essential for the design and operation of isolated microgrids. To this effect, the identification of the related variables and their corresponding classification are presented, together with a model of theoretical expectations about their relationships.

Results:

A model that integrates and describes the behavior of the main variables involved in the operation of microgrids was formulated to analyze the possible implementation of policies that guarantee the sustainability of these solutions and enhance the use of renewable energy resources while improving the continuity of the electric energy supply.

Conclusions:

It was possible to show that operation by means of isolated microgrids with the integration of Distributed Energy Resources is a sustainable solution for rural electrification in Colombia, given that it enhances the use of generation resources with a reduced carbon footprint that are present in the territories under study. These microgrids have the potential to improve the living conditions of users by reducing unsatisfied basic needs.
