Installation of Shunt Capacitor Banks (SCBs) and Voltage Regulators (VRs) within distribution system is one the most effective solutions in reactive power control for improving voltage profile reducing losses along feeder. However, presence VRs can deteriorate Stability Margin (VSM) feeders. To address this issue, paper proposes a multi-objective programming model simultaneous optimal allocatio...

Network function virtualization (NFV) and multi-access edge computing (MEC) have become two crucial pillars in developing 5G beyond networks. NFV promises cost-saving fast revenue generation through dynamic instantiation the scaling of virtual network functions (VNFs) according to time-varying service demands. Additionally, MEC provides considerable reductions response time backhaul traffic sin...

Optimal operation of radial distribution networks with automated compensation and reconfiguration requires the solution of a combinatorial optimisation problem, since the variables are the on/off status of capacitor banks and the open/close status of tie-switches. The solution approaches recently proposed use iterative algorithms such as genetic algorithms, simulated annealing and tabu search, ...

The main aim of this work was the maximization energy saving balanced and unbalanced distribution power systems via system reconfiguration optimum capacitor’s bank choice, which were estimated by using a new algorithm: modified Tabu search Harper sphere (MTS-HSSA). results demonstrated that proposed method is appropriate for improving performance compared with other methods reported in literatu...

Significant opportunity for savings in energy and investment through improved performance of power distribution systems exists the optimal placement rating capacitors, a conventionally cost-effective popular reactive compensating technology. A novel capacitor planning (OCP) procedure is proposed large-scale utility systems, which exemplified on an existing circuit approximately 4,000 buses. An ...

This paper reports concerns of capacitor placement in power distribution systems in the locality of a dynamic voltage restorer (DVR). A feedback controlled simulation model of an actual DVR is developed to perform case studies. Cogency of this model is established by associat ing the waveforms from the model with field measurements. Issues relating to expansion of a DVR in the locality of power...

In this paper optimum size and location of capacitors and distributed generations (DGs) are determined simultaneously in a radial distribution network. The objective function includes power losses reduction and voltage profile improvement using ant colony algorithm. Allocation capacitors and of DGs should be carefully determined with the consideration of different planning incentives. It shows ...

One of the most important methods in loss reduction and controlling the voltages of distribution systems is the utilization of the fixed and switched capacitors. To do this, real modelling of the system in actual operational conditions including unbalanced or balanced loading and for actual feeder structure, ie, radial/meshed configuration, are required. In this paper, a new technique for findi...
