dynamic economic load dispatch is one of the most important roles of power generation’s operation and control. it determines the optimal controls of production of generator units with predicted load demand over a certain period of time. economic dispatch at minimum production cost is one of the most important subjects in the power network’s operation, which is a complicated nonlinear constraine...

In this country development of electrical power system particular for transmission line expansion and interconnection of neighbouring power system try to improve system security and economic operation. Due to this province in large scale power system, operation , control and expansion planning for particular system become challenging task to reduce transmission loss as minimum as possible for o...

In this paper, Direct Search Algorithm is implemented to determine the optimal sizes of Type – I Distributed Generators (DGs) and optimal locations such that maximum possible reduction in real power loss is obtained. Type – I DG injects both active and reactive powers. The algorithm searches for all possible locations in the system for a particular size of DG and places it at the bus which give...

A power system, under heavily loaded conditions, is at high risks of probable line outage and consequent voltage instability problem. Real power loss and voltage deviation minimization are reliable indicators of voltage security of power networks. This paper proposes a Particle Swarm Optimization (PSO) based optimal location and sizing of Static Var Compensator (SVC) to

This loss can be reduced by the use of a capacitor in the system, which injects reactive current and also improves the voltage magnitude in the buses. Shunt capacitors are commonly used in distribution system for reactive power compensation. The real power loss in the distribution line is the R.I2 loss which depends on the current and resistance. The radial distribution system is a rugged syste...

Optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. The distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

in this paper, reconfiguration problem of distribution network has been investigated toimprove reliability and reduce power loss by placement of renewable energy sources; i.e. solarcell and wind turbine. for this, four reliability indices are considered in objective function;which are as follows: system average interruption frequency index (saifi), system averageinterruption duration index (sai...

in this paper, a multi-objective reconfiguration problem has been solved simultaneously by a modified ant colony optimization algorithm. two objective functions, real power loss and energy not supplied index (ens), were utilized. multi-objective modified ant colony optimization algorithm has been generated by adding non-dominated sorting technique and changing the pheromone updating rule of ori...
