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 ...

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 ...

Distribution system plays an important role in supplying the electricity from generation to the consumers via transmission system. The power system is one of the most complex systems in the world. Because of the high R/X value the losses in the distribution system is more. The one of the roles of capacitor is reducing the losses in the distribution system. This paper presents an improved method...

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...

This paper proposes an efficient methodology for optimal location and sizing of static shunt capacitors in radial distribution systems to reduce real power loss, improve voltage profile and to maximize total cost saving. The solution methodology has two parts: In part one, the buses to be compensated is identified using loss sensitivity factors. In the second part, modified artificial bee colon...
