Evaluation of the Criteria in the Choice of Energy Storage or Non-Storage in Photovoltaic Systems in the Sahelian Zone

摘要

In order to have a characterization of the criteria determining the choice of energy storage or non-storage in PV systems in the Sahelian zone, we used the research methodology described as a follow-up. First, we identify the criteria that determine the choice of energy storage or non-storage. In the rest of the work, we establish a prioritization of its criteria. Finally, the two phases written above, allowed us to develop an approach characterized by the weighting of the criticality index, which we implemented using the global decision matrixes of the AMDEC method (Analysis of the Modes of Failures of their Effects and Criticism). The validation of the model followed the rigour of the scientific approach through the methodology used. Thus, the validation of the choice of the specific criteria was made on our personal experience in pv, and the recurrence of its criteria in the literature encountered. The validation of the prioritization of the criteria is based on the quality of the results resulting from the rigorous application of the AMDEC method. This work refers to the problem of whether or not to set up an energy storage method to compensate for the off-peak periods (nights and obstacles that occur in the days) of energy production of the photovoltaic system. A determination of the determining criteria, in the choice of energy storage or non-storage in PV systems in the Sahelian zone, was made. The work also made it possible to establish a prioritization of these last criteria. The results obtained show that the proposed method allows for a prioritization of the determining criteria in the choice of energy storage or non-storage in PV systems in the Sahelian zone.
