- Abstract:
- This study focused on an optimization method that combined simultaneously the reliability and the efficiency of radial power distribution systems ( RDS) , minimized active energy losses, through a process of network reconfiguration. The study based on the failure analysis on network branches, with a special concern on the protection system response to faults and the service restoration procedures, in the emergency state. A non-sequential Monte Carlo simulation based on the branch reliability was used to evaluate reliability of the network configurations. Due to a large number of possible configurations and the need of an effcient search, the optimization was made through an improved genetic algorithm (IGA) . In a first step, the method analyed the RDS considering the absence of investment, and in a second step, the possibility of placing a limited number of new tie-switches in certain branches, according to the definitions made by a decision maker. The effective ness of the proposed methodology was demonstrated through the analysis of a 69 bus RDS and by comparison against other reported methodologies.
