Impact Of Cooking Appliances Shifting Hours In Rural Mini-Grids: Case Study In Ethiopia

Paper in proceeding, 2023

Cooking is an essential aspect of daily life in any community. Electric cooking appliances have high power ratings and cyclic operations and thus contribute strongly to a system peak load. Optimal component sizing and cost are highly impacted by the peak loads. Thus, this study investigates how shifting hours of operation may impact mini-grid component sizing and their cost in a village in Ethiopia. The results indicate that shifting hours of electric cooking impacts the size of battery energy storage and solar PV, resulting in a system cost reduction. The results show that cooking appliance shifting to mid-day has a minor impact on optimal component sizing and the cost of mini-grids (total present cost reduced only by 3%).
