Optimizing grid integration of photovoltaic systems for reliable urban energy management: The case of the city of Lubumbashi (DR Congo). (Research)

This thesis deals with the optimization of grid integration of photovoltaic systems for reliable urban energy management: The case of the city of Lubumbashi (DR Congo). The city of Lubumbashi, capital of Haut-Katanga province, is facing a problem of frequent and prolonged power cuts, due to rapid population growth and poorly planned urban sprawl. Between 2012 and 2023, low-voltage consumption rose from 13 041 000 kWh to around 62 848 364 kWh, leading to overloading of the distribution network and regular load shedding. In addition, Lubumbashi faces an electricity supply deficit of over 24%. The research carried out as part of this thesis will be based on a multidisciplinary approach, combining aspects of engineering and energy optimization (smart grid). However, there is little research on the feasibility of a PV mini grid with storage and its possible integration into the conventional grid to solve the electricity access deficit of spontaneous settlements in Lubumbashi. This study aims to fill this gap. The aim of this project is to design and size an optimal integrated photovoltaic (PV) grid-connected system, and to compare its economic and technological performance. The approach adopted combines quantitative data analysis and simulations, making it possible to model different integration scenarios and assess their impact on the urban electricity network of the city of Lubumbashi, more specifically in the Luwowoshi district of the annex commune. To achieve this, surveys of energy requirements and simulations of the energy performance of a PV mini-grid with storage and the possibility of integration into the conventional grid are planned.
