System for real time power grid distribution network control

A system for real time power grid distribution network control, the system comprising:

• at least one processor;
• and
• at least one memory storing computer executable instructions,
• wherein the at least one memory comprises computer executable instructions executable with the at least one processor, to cause the system to:
• monitor in real time a power grid distribution network by receipt and real time analysis of measured power parameters of the power grid distribution network;
• detect an abnormal loading condition in the power grid distribution network based on real-time analysis of the measured power parameters of the power grid distribution network;
• perform, in response to the detected abnormal loading condition resulting from excessive real power, a reconfiguration analysis of the power grid distribution network based on the analysis of the measured power parameters to generate a reconfiguration plan for the detected abnormal loading condition,
• wherein the reconfiguration analysis is based on heuristic logic that combines both depth first trace upstream and downstream along a feeder of the power grid distribution network and breadth first division to other feeders within the power grid distribution system, and
• wherein a result, obtained by performing the depth first trace, with a lowest load transfer index beyond a predetermined index threshold is taken as the reconfiguration plan, if each of results obtained by performing the breadth first division has a number of switching operations beyond a predetermined number threshold.
