0.5.0
With this release, the Flexible Distribution Grid Demonstrator (FLEDGE) was renamed to Multi-Energy System Modeling and Optimization (MESMO).
New features
- Added new optimization problem object (
utils.OptimizationProblem) as main interface for defining optimization problems with functionality to 1) export the standard form for LP / QP, 2) directly interface Gurobi for better performance with large problems. - Overhead line types can now be defined in terms of conductor data and geometric arrangement (Arif Ahmed).
- Added local-approximation variant for linear electric grid model.
- Added linear model set for electric grid model, which enables defining separate linear models for each time step.
- Added power flow solution set, to obtain power flow solutions more conveniently for multiple time steps.
- Added pre-solve method for DER model set, to obtain baseline nominal power time series for flexible DERs.
Changes
- Improved / simplified
define_optimization...()methods for most use cases. - Revised
define_optimization...()methods for new optimization problem object. - Switched from
multiprocesstorayfor parallel processing for performance reasons. - Revised documentation structure, overhauled the architecture documentation and added the configuration reference.
