说明：  Despite the advantages of distributed generations (DGs) in electrical networks, they make some unwanted changes in network short-circuit levels which make new security risks arise. This imposes several new scenarios on the network operation in the presence of DGs. In addition to the mentioned security concerns, reducing network loss is among the objectives constantly sought by system operators. Therefore, this study discusses both the reconfiguration of a distribution network for efficient operation and protection coordination in the form of a multi-objective optimisation problem.
