Setting Up Optimization

The document outlines the technical setup for optimization in LEAP, including solver selection, required settings, and data input requirements for transformation modules and energy storage.

• LEAP supports several solvers for optimization; GLPK, Cbc, and HIGHS are pre-installed, while MOSEK requires a separate license key, and CPLEX and GUROBI must be purchased and installed independently.
• To enable optimization, users must select a Transformation module (typically for electricity generation), create or select a scenario, and set the 'Optimize' variable to 'Yes' or specify a particular solver.
• Optimization calculations require more extensive data than basic simulation, specifically requiring process efficiencies, availability rates, unit capital costs, fixed and variable operating & maintenance costs, and fuel costs.
• Energy storage modeling is exclusively supported during optimization and requires specific data including Starting Charge, Minimum Charge, and Full Load Hours.
• For multi-region models using full energy system optimization, users can optionally model pipelines and transmission networks, a feature not available in simulation or partial optimization scenarios.
