_______________________________________________________________________________________________________ _Abstract: Distribution Feeder Reconfiguration (DFR) is a critical analysis to optimize and control the distribution system and an important function of distribution automation system. Distribution feeders are configured radially. Their configurations may be varied with manual or automatic sw...

The ant colony algorithm is a new technique for combinatorial optimization borrowed from swarm intelligence. This paper outlines an ant colony algorithm to compute the optimal order of restoring sections in a power distribution system. Restoration of distribution feeders after long interruptions creates cold load pickup conditions due to loss of diversity among the loads. The distribution syste...

The reliability of distribution networks is inherently low due to their radial nature, consequently distribution companies (DisCos) usually seek to improve the system reliability indices with the minimum possible investment cost. This can be known as system-oriented reliability planning (SORP). However, there can exist some customers that are not satisfied by their reliability determined by ado...

Parallel restoration is a way to accelerate the black-start procedure of power systems following a blackout. An efficient sectionalizing scheme can reduce the restoration time of a system, taking into account the black-start ability, generation-load balance of subsystems, restoration time of branches, start-up time of generating units, and effects of dispatchable loads and faulted devices. Solv...

Network reconfiguration in distribution system is realized by changing the status of sectionalizing switches to reduce the power loss in the system. This paper presents a new method which applies an artificial bee colony algorithm (ABC) for determining the sectionalizing switch to be operated in order to solve the distribution system loss minimization problem. The ABC algorithm is a new populat...

Nowadays, distribution utilities expend large investments on Distributed System Automation (DSA) based smart secondary substations at load, capacitor, and distributed generator points with installed automatic sectionalizing switches their branches. This article addresses the optimal control operation of systems that minimize wasted energy introducing quantitative qualitative power services to m...

Power distribution systems typically have tie and sectionalizing switches whose states determine the topological configuration of the network. The aim of network reconfiguration of the distribution network is to minimize the losses for a load arrangement at a particular time. Thus the objective function is to minimize the losses of the network by satisfying the distribution network constraints....

This paper proposes an advanced distribution automation planning problem in which emergency-based demand response plans are incorporated during service restoration process. The fitness function of this planning problem consists of various costs associated with fault occurrence in electric distribution systems consisting of the total yearly cost of customers’ interruptions, the total annualized ...

The most common problems encountered in any electrical distribution system are load unbalance and restoring service to healthy zones the case of a fault. on network is not constant varies from feeder throughout day. In event fault, reconfiguration performed balance loads restore zones. Network involves modifying structure by sectionalizing tie switches. Through reconfiguration, can be transferr...
