This paper presents a Genetic Algorithm (GA) based approach for solving optimal Reactive Power Dispatch (RPD) including voltage stability limit in power systems. The monitoring methodology for voltage stability is based on the L-index of load buses. Bus voltage magnitudes, transformer tap settings and reactive power generation of capacitor banks are the control variables. A binary-coded GA with...

Identification of fault locations in capacitor banks is still under development. Although, faults can be detected by an unbalance relay, it cannot identify the location. To address this issue, study proposes algorithm that categorize protection zones, phases, and a bank using phase angle boundary area. The result showed proposed was effective indicating Performance compared with conventional me...

The minimization of annual operating costs in radial distribution networks with the optimal selection and siting fixed-step capacitor banks is addressed this research by means a two-stage optimization approach. first stage proposes an approximated mixed-integer quadratic model to select nodes where must be installed. In second stage, recursive power flow method employed make exhaustive evaluati...

An analysis was made of the application Stud Welding hardware welding technologies depending on welded structures used, duration process, shape stud butt and consumables used. The use CD technology for metalware to thin-sheet panels is substantiated. essence process formation a joint described, which consists in explosive evaporation protrusion at end during discharge capacitor banks, excitatio...

A substantial quantity of real power loss is accounted for the distribution system due to its radial nature. Efficient and secure operation a system, it necessary minimize active system’s voltage stability index (VSI). Power VSI in can be minimized with optimal integration distributed genera

This paper presents an ant colony approach optimization to shunt capacitor placement on distribution systems under capacitor switching constraints. The optimum capacitor allocation solution is found for the system of feeders fed through their transformer and not for any individual feeder. The main advantages due to capacitor installation, such as system capacity release and reduction of overall...

Between the metal–insulator–metal (MIM) capacitor and metal–oxide–metal (MOM) capacitor, the MIM capacitor has a better characteristic of stable capacitance. However, the MOM capacitors can be easily realized through the metal interconnections, which does not need additional fabrication masks into the process. Moreover, the capacitance density of the MOM capacitor can exceed the MIM capacitor w...
