Objective: Since solar energy allows decentralized production of electricity, it can help solve the problem of electrifying isolated sites where a large number of individuals do not have access to energy. This work aims to size a multi-source system for optimal management of the energy produced.
Method: We used an energy management strategy that is an algorithm, which determines at each moment the sharing of power between the different components of the system.
Findings: The sizing tools allowed us to establish relationships between the powers of the components by simple rules, to define the solar power and the storage volume necessary to meet the demand of a load on a given site.
Novelty: This study allowed us to set up an electrical architecture and a control strategy capable of limiting conversion losses and optimizing energy management within the system.
The aim of this study is to produce biogas with household peelings. The peels used are cassava (PM), yam (PI) and plantain (PB) peels. The bibliographic study allowed us to know that this waste has a high yield of biogas. However, the production of biogas with these peelings has acidification problems linked to their acid pH and a high C/N ratio. The use of a digestate from the anaerobic digestion of cow dung as inoculum (I) and a neutralizer such as human urine and cassava effluent allowed the pH to be adjusted around neutrality, which which made it possible to produce flammable biogas with its various peelings.
