In recent years, renewable types of distributed generation in the distribution system have been much appreciated due to their enormous technical and environmental advantages. This paper proposes a methodology for optimal placement and sizing of renewable distributed generation(s) (i.e., wind, solar and biomass) and capacitor banks into a radial distribution system. The intermittency of wind spe...

This study deals with the design of distributed power systems and optimal capacitor placement based on the ANFIS (Adaptive Network Fuzzy Inference Systems) using Mamdani-type fuzzy inference model. Traditionally, this problem of optimal capacitor placement has been solved through various optimization techniques, but it is less accuracy of finding placement and more time consuming. This can be a...

The present day ever escalating power demand moves the operating point ofthe distribution networks in vicinity of voltage stability boundaries.Any small reactive unbalance between generation and demandmay trigger instability, which makes magnitude to fallslowly until a rapid change occurs. This paper presents an adaptive dragonflyoptimization based method for placement shunt capacitor banks wit...

In this paper, to enhance voltage stability of distribution systems, a Network Topology based load flow results are used to calculate Voltage Stability Index (VSI). Then an algorithm for capacitor placement (CP) based on this voltage stability index is implemented to determine the optimal locations, number and size of fixed and/or switched shunt capacitors for voltage stability enhancement, in ...

Capacitors in power systems are used to supply reactive power for the purpose of loss minimization and voltage profile improvement. Besides, appropriate placement of capacitors is also important so as to ensure that system power loss and total capacitor costs is reduced. Most of the capacitor placement techniques assume that the system is balanced and ignore the effect of harmonics. In this pap...

Optimal capacitor allocation in distribution systems has been studied for a long times. It is an optimization problem which has an objective to define the optimal sizes and locations of capacitors to be installed. In this works, an overview of capacitor placement problem in distribution systems is briefly introduced. The objective functions and constraints of the problem are listed and the meth...

In the present deregulated environment, optimal placement of Distributed Generation (DG) and shunt capacitor in the distribution network plays a vital role in distribution system planning. In this paper, an analytical approach for optimal placement of combined DG and Capacitor units are determined with the objective of power loss reduction and voltage profile improvement. Firstly, the DG unit i...

in this paper, we have proposed a new algorithm which combines pso and ga in such a way that the new algorithm is more effective and efficient.the particle swarm optimization (pso) algorithm has shown rapid convergence during the initial stages of a global search but around global optimum, the search process will become very slow. on the other hand, genetic algorithm is very sensitive to the in...

Installation of capacitors in distribution networks is one of the most used procedure to compensate reactive power generated by loads and, consequently, to reduce technical losses. So, the problem consists in identifying the optimal placement and sizing of capacitors. This problem is known in the literature as optimal capacitor placement problem. Neverthless, depending on the location and size ...
