“…Among these methods, network reconfiguration is a method of controlling harmonics with the lowest cost. In Reference , the network reconfiguration is performed to improve the power losses and harmonic distortion. In this study, the location of the capacitor banks is simultaneously determined with the network reconfiguration, and it has been concluded that the simultaneous network reconfiguration and optimizing the location of the capacitor banks have a greater effect on the improvement of the objectives than their separate considerations.…”

One of the concerns of distribution network operators is the presence of harmonics in the network and their related issues. In most practical distribution networks, there is not enough information available about harmonic contents of customers for network operators. On the other hand, the changing nature of harmonic contents makes their evaluation more complex. Accordingly, in this article, for the first time, a new method for evaluation of harmonic distortion level is presented based on the IEEE‐519 standard. The method focuses on impedance characteristics of the network buses and uses the harmonic current and voltage limits, which are determined by the mentioned standard. The proposed method is utilized as harmonic constraint for network reconfiguration of IEEE 69‐bus and practical Iranian 95‐bus distribution networks. The results indicate the effectiveness of the proposed method for evaluation of harmonic distortion level in the distribution network. The proposed method can also be used as a useful tool in distribution networks where harmonic contents of nonlinear loads are not available.

“…Reconfiguration as a solution for power quality problems has been considered vastly. To improve power quality criteria and reduce active power losses for a distribution network with nonlinear loads, a particle swarm optimization (PSO)‐based algorithm has been proposed for grid reconfiguration and capacitor allocation . Effects of network reconfiguration on harmonics and voltage sag have been investigated in Jazebi et al Since power quality and reliability issues are in deep relationship, both of them have been considered as the reconfiguration aim.…”

Summary Traditionally active power loss and power quality issues are major concerns in distribution network management. Nowadays, these concerns become more important by integrating distributed energy resources (DERs) in the networks. Network reconfiguration has been adopted as an effective remedy. In this paper, loss reduction and improvement of power quality indices such as total harmonic distortion (THD) and voltage sag are modeled as a multi‐objective problem. The function is weighted sum of terms, which are dealt with each objective. To solve the problem, branch exchange method for the network reconfiguration is modified. In the proposed algorithm, branch exchange operation iterates sequentially. Then, the yielded solution is compared with the best one that has been saved in the memory unit. Because memory is utilized in the method, it is called retentive branch exchange. Application of the proposed method is validated by planning and simulating six scenarios for an unbalanced radial 25‐bus network. For different operation conditions and power quality disturbances, simulation results show high ability and effectiveness of the proposed method.

Nowadays, due to the increasing electrical demand, optimal operation of distribution network has taken much attention. To reach this goal, 1 of the useful methods is the implementation of custom power devices. This paper tries to investigate the unified power quality conditioner (UPQC) placement and sizing along with distribution network reconfiguration for the reactive power compensation in the radial distribution system. This approach finds the optimal sizing and location of UPQC and the optimal changing of the switches status between feeders. Real power loss reduction is the chief function of this work. The proposed method is applied on the 69-bus radial distribution test system.To check the feasibility and effectiveness of the proposed methodology, various scenarios of reconfiguration and UPQC placement are taken into account at different load conditions. Results show that the network reconfiguration with the placement of UPQC provides lower energy losses compared with other methods.
