In this paper, the performance of two types of FACTS devices in order to enhance the power system static voltage stability has been investigated. These devices include Static Var Compensator (SVC) and Thyristor Controlled Series Capacitor (TCSC). The modeling of the Single Machine Infinite Bus (SMIB) and aforesaid devices has been made up in steady state mode with disregarding of the generator ...
Taking maximum power transmission and power stable transmission as research objectives, optimal design for the wireless power transmission system based on magnetic resonance coupling is carried out in this paper. Firstly, based on the mutual coupling model, mathematical expressions of optimal coupling coefficients for the maximum power transmission target are deduced. Whereafter, methods of enh...
Despite the fact that transmission network has a vital role in electricity markets and cost of transmission expansion is considerable, but transmission charges represent a small percentage of power system operating costs. Thus, transmission cost allocation should be a reasonable economic indicator to make decisions on facility allocation, transmission expansion and other similar market tasks. ...
The 330kV power transmission system in Nigeria is associated with numerous problems ranging from voltage instability, ageing network, long and weak lines insulators, absence of protection schemes on the distribution lack spinning reserve to compensate for shortages, obsolete substation equipment, higher losses which substantially affect reliability supply Nigeria. This study aimed at analysing ...
