Topic > Reconfiguration of distribution feeders for voltage drop minimization

Abstract—This paper proposes a new method for reconfiguring the electricity distribution network based on regular operational prerequisites to limit active losses on the community or to balance the load on the power supplies. The idea behind the reconfiguration is to understand the recommended load transfers so as to minimize energy losses and meet the prescribed voltage limits. The proposed method determines the acceptable gadget topology that reduces energy loss based on a load model. The effectiveness of the proposed approach is tested on a bifurcated 11 KV power supply in the distribution (consumer end) of three phase 440 V and single phase 230 V. The evaluation of the proposed strategy consists in terms of improvement of the voltage profile before and after the bifurcation, load balancing before and after bifurcation at the consumer end of the distribution network.

Introduction Distribution grid system is an important part of the energy system that connects distribution lines with consumers. Nowadays, distribution networks are growing rapidly; therefore an efficient operating method is essential to reduce costs and increase the effectiveness of operation. Between 30 and 40% of total investments in the electricity sector are allocated to distribution systems, which however have not received the technological impact in the same way as generation and transmission systems. Many of the distribution networks operate with minimal monitoring systems, mainly with local and manual control of capacitors, disconnectors and voltage regulators, and without adequate computational support for system operators. There are many losses in the distribution system such as voltage drop, poor power factor, power theft, distribution system failure, poor supply reliability etc. Merlin et al. [1] using a discrete branch & bound technique in order to increase the efficiency of the electricity distribution network considering the reconfiguration of the power supply. In this method, all network switches are closed to form a mesh system, and then the switches are opened later to restore the radial configuration. However, this method involves approximations. Shirmohammadi et al. [2] proposed an algorithm to overcome these approximations. In this method the switches are opened one by one, based on an optimal flow pattern. Peponis et al. [3] developed a methodology for the optimal operation of the distribution network. In this method, minimization of losses is achieved by installing shunt capacitors and reconfiguring the network. Schmidt et al. [4] formulated the problem as a mixed integer nonlinear optimization problem. The integer variables represent the state of the switches and the continuous variables represent the current flowing through the branches. Broadwater et al. [5] considered time-varying load demand, obtained through load estimation, to reduce the loss. Mortom et al. [6] proposed a method based on an exhaustive search algorithm to obtain a minimum loss radial configuration of the distribution system. How can we reduce these types of losses:-· Network reconfiguration. ·HVDS The network is reconfigured to reduce the.In conditions of permanent fault, the network is reconfigured to restore service, minimizing the areas without interruption of supply.
