| dc.description.abstract | The transition to electric cooking has the potential to significantly impact the low voltage distribution network in Uganda. This project aimed to assess the effects of electric cooking on the
network, focusing on load profiles, system losses, transformer loading, and voltage fluctuations.
To conduct the study, data was collected from three transformer zones operated by UMEME.
Two transformers were operating at moderate loads, while one was on the verge of being overloaded. The collected data was used to model the transformers in the DigSilent Power Factory
software, enabling the evaluation of their current performance and loading characteristics. To
simulate the impact of electric cooking, incremental cooking loads were added to the system,
ranging from 10% to 100% penetration. The key results obtained include load profiles, system
losses, transformer loading, and voltage fluctuations. Based on the analysis, it was observed
that moderately loaded transformers can support up to 40% uptake of electric cooking. However, transformers that are nearing their maximum capacity can only support a 20% uptake of
electric cooking. This finding highlights the importance of considering the existing transformer
load when planning for the integration of electric cooking into the low voltage distribution
network. To mitigate the potential overloading of transformers, the project recommends the
implementation of transformer separation. For example, replacing a single 200kVA transformer
with two separate 100kVA transformers at different points in the network would reduce the
load distance and subsequently minimize voltage drops. By understanding the impact of electric cooking on the low voltage distribution network in Uganda, this project provides valuable
insights for network planners and policymakers in ensuring a smooth and efficient transition to
electric cooking while maintaining the reliability and stability of the distribution network. | en_US |
