System and method for supporting creation of system plan to change configuration of power system

A system for supporting creation of a system plan to change a configuration of a power system including a power transmission system and a power distribution system, the system comprising:

• one or more processing devices;
• and
• one or more storage devices,
• wherein the one or more storage devices are configured to store information on a configuration of the power transmission system and information on a configuration and a load of the power distribution system, and
• wherein the one or more processing devices are configured to:
• determine, based on the information on the configuration and the load of the power distribution system, a load accommodation capacity between power distribution substations which indicates a power supply capacity allowed to be compensated for between the power distribution substations through a configuration change of the power distribution system;
• create a system plan proposal including a change in system configuration of the power transmission system and the power distribution system based on the load accommodation capacity;
• and
• output information on the system plan proposal to an output device.
