FLEDGE - Flexible Distribution Grid Demonstrator#
The Flexible Distribution Grid Demonstrator (FLEDGE) is a software tool for optimal operation problems of electric and thermal distribution grids along with distributed energy resources (DERs), such as flexible building loads, electric vehicle (EV) chargers, distributed generators (DGs) and energy storage systems (ESS). To this end, it implements 1) electric grid models, 2) thermal grid models, 3) DER models, and 4) optimal operation problems.
