Techno-Economic Preliminary Assessment of a Solar PV Microgrid Integration into Mangamazini Rural Settlement Network

In recent years, microgrid systems have emerged as a promising energy solution, especially to rural communities which are in crescendo need of generation capacity to meet power demand due to particularly, the rising of rural-urban migrations. In addition to load shedding challenges, the Mangamazini village under eThekwini Municipality in South Africa has had at least two power outages in a fortnight for the last three years, depriving residents of essential services. This paper explores the integration of solar photovoltaic (PV) microgrid systems into the utility network with the aim to improve system reliability by curbing unplanned outages. The primary objective of the project is to analyze the feasibility and potential benefits of implementing microgrid technologies in the selected area, while taking into consideration its unique, socio-economic, and environmental contexts. In this paper, using ReticMaster® software, the technical and financial comparative assessments of the project are performed through various scenarios, and the findings ascertain that the integration of microgrid systems yields numerous benefits such as enhanced energy access, substantial improved reliability, and increased utilization of renewable energy sources. Furthermore, the study reveals various challenges to be considered to ensure successful microgrid integration. Some of the findings can also serve as foundational ground for future research, policy development and insights with regards to microgrid integration in a typical rural settlement. Indeed, by leveraging microgrid technology benefits, the municipality can take significant strides toward attaining its rural electrification targets and positively contributing to the well-being of its underserved communities.
