New assets

Added new assets: Plant (e.g. CCGT or electrolyzer) and OrderBook (e.g. LNG shipments or intraday power trades). Also added requirements.txt

Split optimization

Added functionality to break optimization into smaller chunks. E.g. to perform an optimization for each week in a year

Changes to CHPAsset ramps

Update to the conversion of start and shutdown ramps in CHPAsset

Added CHP Asset

• Added a detailed CHP asset with startup, shutdown and ramping behaviour as well as a detailed model on heat delivery

Added periodicity & sped up building problems

Periodicity - create assets that show periodic behaviour. May help e.g. to reduce problem size where we can exploit strong periodic characteristics

Speeding up - improved vectorization and usage of numpy to speed up building optimization problems. Issue addressed was (slow) putting together the portfolio LP from asset LPs

bug fixes and amended sample

v1.1.8

version up

Added multi-timescale functionality

Each asset can come with its own timescale. Use case is an efficient optimization of assets in a portfolio that live on different time scales. Please check the sample in the documentation

Added multi commodity assets

Define assets to convert commodities (gas2power, power2x, …) and link markets for various commodities

Added MIP asset capability & storage extension

Integrated MIP capabilities:

• mappings allow for new attribute "bool" for variables --> MIP
• first example storage with "no simultaneous dispatch in & out" (requires MIP)
