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 ...

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...

– Electricity, today, has not only become a necessity but also a tool for determining the economic standing and growth of a nation. The exponential growth in demand over the past two decades and the widening gap between demand and supply is a growing concern. So as to reduce this gap, in addition to adding new generating units, automation technology is being employed for reducing the T&D losses...

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...

This paper represents the Gravitational Search Algorithm (GSA) that can be used to determine the optimal location and rating of Thyristor controlled Series Capacitor (TCSC). TCSC is equipment used to regulate and improve power flow in power system. The method used in this study was GSA. TCSC were the implemented on 500kV Java-Bali Power System. Loadflow results before optimization using Newton ...

The allocation of distributed generation and capacitor banks is critical for success in the planning power grids. A methodology developed optimal placement renewable (wind photovoltaic powers) based on technical economic parameters. In order to preserve horoseasonal stochastic dependence nature wind solar power, uses a model that integrates sequential Monte Carlo method diagonal band Copula mod...

An efficient distribution network must be able to supply power with good voltage profile. The main objective of the proposed work is to allocate losses of the unbalanced distribution network by the firefly algorithm in regulated and deregulated environments before and after loss minimization. Reconfiguration is one of the methods for loss reduction of unbalanced distribution network. Further, o...

The ...

Noise on a dc power bus that results from device switching, as well as other potential mechanisms, is a primary source of many signal integrity (SI) and electromagnetic interference (EMI) problems. Surface mount technology (SMT) decoupling capacitors are commonly used to mitigate this power-bus noise. A critical design issue associated with this common practice in high-speed digital designs is ...

In the present day world power system deregulation is at its full stretch. In this deregulated environment ensuring that the power system operates with in its specified limits, which have been traditionally referred to as power system security is the most concerned aspect, which is currently being given at most importance. The term reliability depends on transmission loss. Maintaining the secur...
