“…It is a fast method compared to dynamic studies, and unlike PV curves, it has fewer problems when it comes to convergence [11]. Also, it is a widely used tool: Recent studies have reported using simulation software such as PSSE [12], DigSilent [13], PowerWorld [14], NEPLAN [15], Matlab [16], and Python [17] to develop QV curves in real and test circuits. The analysis of these curves, and if possible, complemented with other voltage stability criteria such as modal or sensitivity analysis, helps to study the reactive power margins, determine the most suitable areas to install reactive compensation, and make planning decisions in the long and medium term.…”

Radial High-Voltage networks have problems ensuring voltage stability when a fault occurs. Among preventive actions for these events, installing reactive power compensation in the most vulnerable zones to voltage instability is an economical and simple alternative. Previous works have used the QV curves methodology based on contingency power flows to identify such zones. However, this method has been criticized because it does not consider the dynamical effect of some network elements that depend on the voltage levels, especially in contingency scenarios. This article proposes a QV curve analysis based on the operating point resulting from dynamic simulations to amend this critique. To evaluate the proposed procedure, the model of the Patagonian High-Voltage Network in southern Argentina is used through the PSS/E software with the help of the Python programming language. The results detect the most vulnerable areas to voltage instability after a fault occurs and the reactive power necessary to maintain voltage levels in an acceptable operating range. The proposed methodology can be applied to other networks. For example, it can be used in the Latin-American context to assess future network expansions, especially on those linking countries, such as Ecuador with Perú or Colombia, or even the Centro American Interconnected System.

“…Here ETAP (electrical transient analysis program) simulation tool is used for evaluation purpose to calculate the power flow, stability and short circuit study of northeast and in detail Kabul national grid of Afghanistan. Actual data as per latest update single line diagram map is used for generators, transformers, loads, transmission lines, all buses, circuit breakers, lines and cables and switches for voltage level improvement on each bus and line [5]. Power flow studies are performed on an electric network to make sure that the electrical network power transfer from generation station to the load end is stable, efficient, economic and reliable [6].…”

Electrical power is the base and backbone of all technologies and improvements, with an increase in load in day to day life, the need for utility has also grown up tremendously so as to fulfill the load requirements. Load flow study shows an insight regarding active and reactive power on each line, voltage phase angles on each bus and voltage losses on transmission lines, cables, transformers, and entire system of a grid. Short circuit study is most needed on electrical networks in order to properly size different equipment's and devices used in a system so as to properly handle short circuit currents. Stability analysis is essential for both design and performance monitoring for reliable and efficient grid operation. In this research work a vast and detailed investigation of status and performance evaluation of power system in North East Afghanistan had been performed. Particularly performance evaluation is applied on Afghanistan’s national power grid and concentrated on Kabul super grid. Kabul super grid is deeply evaluated by its modeling and performance evaluation. Evaluation of the network is performed based upon the power losses, voltage status, transmission line loading, and harmonic study as per the power flow results.
