The classical optimization problem for reducing investment costs and energy loss in radial distribution systems is addressed through a strategy of linear approximations and new variable representation. The linear approximation of the problem is performed in two main aspects: one is by using Support Hipper-planes (SH) allowing the approximation of the loss function in each branch of the distribu...

2 Professor, Electrical Engineering, (India) ABSTRACT The power distributed into the network has losses, which is greater in distribution system compared to transmission system. Capacitors have been employed to provide reactive power compensation in distribution systems to resolve this problem. These are used to reduce power losses and to maintain the voltage profile within acceptable limits. T...

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...

An input/output feedback linearization control strategy is developed for control of three-level three-phase neutral-point-clamped rectifier using its dual Lagrangian modeling. The load current of the rectifier can be given in two forms: (i) the load current involving the current of capacitor C1 (ii) the load current involving the current of capacitor C2. Applying the obtained load current to th...

We have performed self-consistent, three-dimensional (3-D), time-domain calculations for a bounded-wave electromagnetic pulse simulator. The simulator consists of a constantimpedance transverse electromagnetic structure driven by a charged capacitor, discharging through a fast closing switch. These simulations yield the detailed 3-D electromagnetic field structure in the vicinity of the simulat...

This paper provides a new approach in decision making process for shunt capacitor placement in distribution networks. The main core of the evaluation process is a multi-objective framework to allocate the capacitor banks. The power loss and the total harmonic distortion (THD) are the objective functions of the system under study in a long-term planning horizon. In order to select the executive ...

Power generated in generating station is transmitted through transmission lines and fed to the consumers through distribution substation. The power distributed in to the network has losses, which is greater in distribution system than the transmission system. This problem could be addressed by placing capacitor at strategic location due to which the kW loss can be minimized by improving the vol...

This paper presents, with a solid conclusion, practical, hands-on applied EMC information for engineers that can be put to immediate use without relying on the mathematics of Maxwell's equations. An examination is made to determine if the physical placement of decoupling capacitors makes a significant difference in the development and propagation of radiated emissions from a printed circuit boa...

Reduction of total losses in distribution system is very essential to improve the overall efficiency of power delivery. This can be achieved by placing the optimal value of capacitors at proper locations in radial distribution systems. The proposed methodology is a fuzzy-genetic approach. The best location of the capacitor is determined using fuzzy set theory and the sizing of the capacitor is ...

A new method of Second order PSO for a more effective capacitor sizing in radial distribution feeders to reduce the real power loss and to improve the voltage profile is proposed. The location of the nodes where the capacitors should be placed is decided by a set of rules given by the fuzzy expert system and the sizing of the capacitors is modeled by the objective function to obtain maximum sav...
