“…Power flow solvers are a key technology for the simulation of power networks. A large variety of commercial, for example, Digsilent PowerFactory, PSS/Sincal, CYME, and open, for example, OpenDSS (Dugan & McDermott, 2011), GridLab‐D, OPEN (Morstyn et al, 2020), pandapower (Thurner et al, 2018), and unbalanced power flow tools are available. An even larger number of open source energy tools do not actually include an unbalanced power flow solver despite sometimes being used in the context of power distribution modeling, for example, HOMER, Calliope, OSeMOSYS, PLEXOS, TIMES, and PowerGAMA use active power only/power balance approaches.…”
