GridLAB-D A power distribution system simulation and analysis tool Developed by the U.S. Department of Energy (DOE) at Pacific Northwest National Laboratory (PNNL) BSD-style license: vendors can add or extract their own modules and have almost no restrictions on the redistribution of the SW components. 23/11/2018 ISMB – Copyright 2013

GridLAB-D Main Features Agent-based modeling tool Handles time scales ranging from sub-seconds to many years clock { timezone PST+8PDT; starttime '2001-01-01 00:00:00 PST'; stoptime '2001-01-01 23:59:59 PST'; } Supports the modeling of: 3-phase, unbalanced (meshed or radial) power systems end-use load behavior of thousands to millions of homes and appliances retail level markets and related controls distributed generation and storage demand response and direct load control 23/11/2018 ISMB – Copyright 2013

Residential Model Typical single-family residential units in North America. They are defined with 110/220 volt distribution panels that allow various end-use loads to be connected. 23/11/2018 ISMB – Copyright 2013
