PROFILE

Rachel Maier

Over a two-month period, contributed to the FZJ-IEK3-VSA/FINE repository by developing and refining dynamic conversion features for energy system modeling. The work focused on implementing binary operation capabilities within the ConversionDynamic component, involving a core refactor to support extensible operator frameworks and enhance model flexibility. Further improvements included enabling cyclic constraints and migrating timing semantics from discrete steps to hourly units, controlled by a configurable flag. These changes were realized through object-oriented programming and constraint programming techniques, primarily using Python and Pyomo, with careful attention to maintainability, traceability, and streamlined unit testing throughout the development process.

Month: 2025-07 — Focused on expanding dynamic conversion capabilities and aligning timing semantics with business needs. Key work centered on enabling cyclic constraints in Dynamic Conversion and migrating timing units from steps to hours, with a configurable flag to control behavior. Refactored ConversionDynamic to support cycles, updated upTimeMin/downTimeMin to hourly units, introduced useTemporalCyclicConstraints to control this behavior, refined constraint generation logic, and removed redundant test files. The work was implemented with a concise commit (37ac81533dcdcf6e0a73dc2764c9d397d9bbfe41).
