This paper presents a new method to solve the network reconfiguration problem. The uncertainty of system loads on different feeders which vary from time to time makes the distribution system operation and its control more complex. For a fixed network configuration power loss is not minimum in a distributed network. Hence, there is a necessity for reconfiguration of the network. Network reconfig...

This paper presents an Enhanced Marine Predators Algorithm (EMPA) for simultaneous optimal distribution system reconfigurations (DSRs) and distributed generations (DGs) addition. The proposed EMPA recognizes the changes opportunity in environmental climatic conditions. handles a multi-objective model to minimize power losses enhance voltage stability index (VSI) at different loading levels. is ...

In the context of modern power systems the multi objective feeder reconfiguration problem has assumed significant importance. This paper presents a fuzzy set theory based approach for the multi objective network reconfiguration of distribution system. The multiple objectives which are met are feeder balancing, minimize power losses, feeder-current constraints and deviation of node voltage. The ...

Distribution systems can be operated in multiple configurations since they are possible combinations of radial and loop feeders. Each configuration leads to its own power losses and reliability level of supplying electric energy to customers. In order to obtain the optimal configuration of power networks, their reconfiguration is formulated as a complex optimization problem with different objec...

in this paper, reconfiguration problem of distribution network has been investigated toimprove reliability and reduce power loss by placement of renewable energy sources; i.e. solarcell and wind turbine. for this, four reliability indices are considered in objective function;which are as follows: system average interruption frequency index (saifi), system averageinterruption duration index (sai...

A huge power is dissipated in distribution systems as power losses. The loss reduction and bus voltage improvement are the critical parameters of effective distribution feeder power flow. There are several techniques followed for power loss reduction and voltage profile improvement in distribution systems. Specifically, Distribution Feeder Reconfiguration (DFR) method is employed for the propos...

This paper presents a novel approach for optimal reconfiguration of radial distribution systems. Optimal reconfiguration involves the selection of the best set of branches to be opened, one each from each loop, such that the resulting radial distribution system gets the desired performance. In this paper an algorithm is proposed based on simple heuristic rules and identified an effective switch...
