Reinforcement Learning for Optimal Protection Coordination
2018 International Conference on Smart Energy Systems and Technologies (SEST), 2018 The design of reliable protection systems is essential in order to guarantee the secure operation of power systems. The coordination of the response of protective equipment under fault conditions is a fundamental problem which is usually formulated as a non-linear optimization problem with the objective of minimizing the total operating time of the ...

Protection Coordination in Networks with Renewable Energy Sources [PDF]
, 2014 The increased distributed generators (DGs) in distribution networks are causing protection coordination problems. Due to the many generation sources supplying the distribution network, the conventional protective devices have become insufficient to ensure the proper protection coordination in case of a fault.This dissertation illustrates the summary of
