many simulation algorithms (chemical reaction systems, differential systems arising from the modeling of transient behavior in the process industries and etc.) contain the numerical solution of systems of differential equations. for the efficient solution of the above mentioned problems, linear multistep methods or runge-kutta technique are used. for the simulation of chemical procedures the ra...

In this paper a best method of fault locating in a radial power distribution system is discussed. The history associated with fault occurred in power system can be effectively used as a strong database. This database will act as the trainer to the fuzzy expert system. In this paper methodology based on fuzzy expert system is discussed for assistance to the operators for easy fault detection.Ele...

This paper presents a simple three phase load flow method to solve three-phase unbalanced radial distribution system (RDS). It solves a simple algebraic recursive expression of voltage magnitude, and all the data are stored in vector form. The algorithm uses basic principles of circuit theory and can be easily understood. Mutual coupling between the phases has been included in the mathematical ...

This paper presents a simple three phase load flow method to solve three-phase unbalanced radial distribution system (RDS). A three phase load flow solution with considering most of load modeling is presented which has good convergence property for any practical distribution networks with practical R/X ratio. It solves a simple algebraic recursive expression of voltage magnitude, and all the da...

The majority of outage events experienced by customers are due to electrical distribution failures. Increasing network reliability is a necessity in order to reduce interruption events. Distribution network automation can trim down outage events and increase system reliability. Network automation has to be done using optimization approaches. Genetic Algorithm (GA) is a relatively new technique ...

To minimize power losses, it is important to determine the location and size of local generators to be placed in unbalanced power distribution systems. On account of some inherent features of unbalanced distribution systems, such as radial structure, large number of nodes, a wide range of X/R ratios, the conventional techniques developed for the transmission systems generally fail on the determ...

In recent years the use of renewable energy sources (RES) by many power grid companies worldwide has increased significantly. The trend towards RES is mainly due to environmental issues and rising fuel prices associated with conventional electricity generation. This paper introduces a hybrid approach find optimal location size distributed generations (DG) in radial distribution system (RDS). pr...
