Modélisation systémique pour l'optimisation multi-objectifs de systèmes énergétiques – Application aux micro-réseaux électriques isolés.

Abstract : Climate change and the depletion of some natural resources are leading to changes in social expectations toward the energy production. The development of new power supply systems must therefore take into account various impacts. One of the evolutions of the electrical mix consists in the gathering of production (conventional and renewable) and storage technologies inside a local network : a microgrid. This PhD thesis proposes to design microgrids by considering several economic, technical and environmental objectives. The developed approach consists in the consideration of management aspects in the design parameters of microgrids and the integration of the modelling into a non-weighted multi-objective optimization algorithm.A decision-support tool has been developed. After identifying the stakes of energy system modelling and optimization, a sequential simulation of microgrids operation has been set up, enhanced with various performance indicators (technical, environmental and economic) and implemented in a genetic algorithm. The sequential simulation has been carried out on a representative period of twelve typical days, while guarantying the reliability of of the performances assessment on a longer operation period. Several solutions, trade-offs between the objectives, have been found. Their diversity in terms of performances and parameters allows to extend the design space. Furthermore, the impact of the consideration of several management strategies allows to find more diverses combinations of technologies. These results have been analyzed and the assessment and optimization requirements have been checked on a realistic case study. Eventually, the performance of the approach has been validated by comparison with other software (HOMER and iHOGA/MHOGA).
