LuSim est con\u00e7u pour faciliter l'\u00e9valuation du rendement \u00e9nerg\u00e9tique des syst\u00e8mes photovolta\u00efques dans les cas o\u00f9 la g\u00e9om\u00e9trie, les mat\u00e9riaux et l'environnement ont un impact important sur la distribution de l'irradiation, les pertes du syst\u00e8me et le rendement \u00e9nerg\u00e9tique qui en r\u00e9sulte. Plut\u00f4t que de s'appuyer sur des abstractions simplifi\u00e9es, il vise \u00e0 repr\u00e9senter les syst\u00e8mes photovolta\u00efques tels qu'ils existent dans des environnements r\u00e9els, en mettant explicitement l'accent sur la variabilit\u00e9 spatiale et les effets g\u00e9om\u00e9triques.<\/p>

L'approche de la mod\u00e9lisation privil\u00e9gie la coh\u00e9rence physique, la transparence des hypoth\u00e8ses et la compatibilit\u00e9 avec les processus d'ing\u00e9nierie \u00e9tablis.

LuSim met en \u0153uvre une cha\u00eene compl\u00e8te de simulation du rendement \u00e9nerg\u00e9tique photovolta\u00efque dans un cadre unique et coh\u00e9rent, depuis l'\u00e9valuation de l'irradiation jusqu'\u00e0 la production d'\u00e9nergie \u00e9lectrique et les pertes du syst\u00e8me.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

LuSim follows a complete PV energy yield modelling chain, from the evaluation of irradiance in complex environments to the estimation of electrical power and energy yield at system level. Each step of the simulation is based on established engineering practice and relies on scientifically validated models.<\/p>

High-resolution irradiance modelling in complex 3D environments provides the physical basis of the simulation. This irradiance is converted into electrical power and energy yield using photovoltaic performance models that account for module behaviour, temperature effects, and system-level losses. Particular attention is paid to maintaining consistency across the modelling chain, ensuring that assumptions made at one stage remain compatible with subsequent steps.<\/p>

LuSim int\u00e8gre une combinaison de biblioth\u00e8ques open source et de mod\u00e8les d\u00e9crits dans la litt\u00e9rature scientifique. Des outils open source tels que pvlib sont utilis\u00e9s le cas \u00e9ch\u00e9ant pour garantir la transparence et l'alignement sur les pratiques valid\u00e9es par la communaut\u00e9. Lorsque des mod\u00e8les pertinents sont d\u00e9crits dans la litt\u00e9rature mais ne sont pas disponibles sous forme d'impl\u00e9mentations open source pr\u00eates \u00e0 l'emploi, ils sont impl\u00e9ment\u00e9s directement dans LuSim sur la base de leurs formulations publi\u00e9es.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Scientific grounding and model transparency <\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

LuSim integrates a combination of open source libraries and models described in the scientific literature. Open source tools such as pvlib are used where appropriate to ensure transparency and alignment with community-validated practices. When relevant models are described in the literature but are not available as ready-to-use open source implementations, they are implemented directly in LuSim based on their published formulations.<\/p>

By relying on peer-reviewed models rather than proprietary formulations, LuSim ensures consistency with current scientific knowledge while preserving flexibility in model selection. Each step of the PV energy yield simulation is defined by its scientific validity and its relevance to the problem being addressed.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

No modelling approach is universally optimal. LuSim has been designed for cases where geometry-driven effects and spatial variability cannot be neglected.<\/p>

Its scope and assumptions are explicitly defined, allowing users to understand where the approach provides added value and where simpler methods may be sufficient. This clarity is essential for interpreting results correctly and for integrating them into broader engineering and financial workflows.<\/p>

By making limitations explicit rather than implicit, LuSim supports informed modelling choices rather than black-box usage.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

LuSim ne vise pas \u00e0 remplacer toutes les m\u00e9thodes de simulation photovolta\u00efque existantes. Il les compl\u00e8te en traitant les cas o\u00f9 les hypoth\u00e8ses g\u00e9om\u00e9triques simplifi\u00e9es ne sont plus ad\u00e9quates.
Cela permet l'analyse d'effets d\u00e9pendants du temps tels que l'\u00e9volution de l'ombrage, le comportement du suivi et la variabilit\u00e9 saisonni\u00e8re, ainsi que des motifs spatiaux qui influencent les performances du syst\u00e8me, les pertes par d\u00e9sadaptation, les m\u00e9canismes de d\u00e9gradation et l'incertitude.
Le choix de l'approche de mod\u00e9lisation doit toujours \u00eatre guid\u00e9 par la nature du syst\u00e8me et les questions \u00e0 traiter.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
