summary & overview

Comparison with HOMER ENERGY by UL

HOMER Energy uses a single node and gives investment advice for a single year. Additionally, HOMER Energy uses combinatorial optimization: Users have to predefine sets of capacity expansion, and only the operation is calculated for each possible combination of the provided sets.
