Summary Distribution network reconfiguration is a common method to achieve objectives such as minimization of power loss and voltage deviations. There exist several different algorithms to find the optimal configuration of network. Almost all of these algorithms consider the main operational constraints such as voltage, current, and power limits. Although it is crucially important to incorporate protective devices and their constraints in the reconfiguration problem, there are few works in network reconfiguration considering protection system. Accordingly, this paper presents a new reconfiguration algorithm considering protective constraints in the presence of distributed generation (DG) units. The objective function of this paper is power loss, which is minimized subject to both operation and protection constraints. In addition to the protection constraints, the effects of DG units on the reconfiguration are considered in this work. Uncertainties in loads and power generation of DG units are also investigated, using a new scenario‐based algorithm. Two test systems are utilized to illustrate the efficiency of the proposed method and to compare it with conventional approaches. Moreover, in order to evaluate the performance of new scenario‐based algorithm, it is compared with Monte Carlo simulations.

“…In 1986, Grainger and Lee have removed some unrealistic assumption made by previous researchers and implemented easily and readily modified, adapted, and extended based on system conditions, and also presented single radial feeder with possibly several sections for different wire sizes, and for any known reactive‐load spread along the feeder irrespective of load distribution, one can determine the size and location of the shunt capacitors. In 1982, Bunch et al developed a control strategy and digital processor algorithm for improved voltage control and reactive power compensation at both distribution substation and feeder level; also, this work has been advanced as a part of the development of the integrated distribution control and protection system prototype for electric power and research institute. In 1983, Grainger et al introduced continually controlling, capacitive compensation strategy for a primary feeder which assists DAS being considered for implementation of electric utilities who heavily depend on substation‐based computers for reactive power control primary distribution feeders.…”

Summary In an electrical power system, the generated power is transferred through a high voltage transmission system, and it reaches the low voltage consumers at the distribution side. In a distribution system, I2R loss is very high compared with the transmission system due to high trueRX ratio, high current, and low voltage. It is a known fact that the economic enticement of distribution companies (DISCOMs) is to minimize losses in their networks. In general, this enticement is the difference in cost obtained between real and standard losses. Thus, when real losses are more than the standard losses, the DISCOMs are penalized economically, or when the opposite occurs, they earn a profit. Hence, loss minimization problem in distribution systems is a well‐suitable researched topic for researchers. Various approaches are investigated and implemented to solve the loss minimization problem in the past. However, these are different from each other by choice of loss minimization tool, problem formulation, methods employed, and the solution obtained. Several methods exist for loss minimization like capacitor allocation, network reconfiguration, distributed generation (DG) allocation, feeder grading, high voltage distribution system, etc. The present article gives a literature review, general background, and comparative exposition of the most often used techniques: (a) network reconfiguration, (b) capacitor allocation, (c) DG allocation, and (d) DSTATCOM allocation for loss minimization in distribution system and its combination versions for achieving maximum potential benefits are (e) simultaneous reconfiguration and capacitor allocation, (f) simultaneous reconfiguration and DG allocation, (g) simultaneous DG and DSTATCOM allocation, and (h) simultaneous reconfiguration, capacitor, and DG allocation based on several published articles. This will make the literature easy to new researchers working in this area.
