“…Many OSs use shunt capacitor switching to modify PS's reactive power flows and so the OSs optimize the PS. Such OSs are presented in [77][78][79][80][81][82]. OS in [83,84] optimize reactive power flows in a PS by changing the taps of on-load tap changers in transformers.…”

Optimization systems (OSs) allow operators of electrical power systems (PS) to optimally operate PSs and to also create optimal PS development plans. The inclusion of OSs in the PS is a big trend nowadays, and the demand for PS optimization tools and PS-OSs experts is growing. The aim of this review is to define the current dynamics and trends in PS optimization research and to present several papers that clearly and comprehensively describe PS OSs with characteristics corresponding to the identified current main trends in this research area. The current dynamics and trends of the research area were defined on the basis of the results of an analysis of the database of 255 PS-OS-presenting papers published from December 2015 to July 2019. Eleven main characteristics of the current PS OSs were identified. The results of the statistical analyses give four characteristics of PS OSs which are currently the most frequently presented in research papers: OSs for minimizing the price of electricity/OSs reducing PS operation costs, OSs for optimizing the operation of renewable energy sources, OSs for regulating the power consumption during the optimization process, and OSs for regulating the energy storage systems operation during the optimization process. Finally, individual identified characteristics of the current PS OSs are briefly described. In the analysis, all PS OSs presented in the observed time period were analyzed regardless of the part of the PS for which the operation was optimized by the PS OS, the voltage level of the optimized PS part, or the optimization goal of the PS OS.

“…In this regard, these indicators may seem to be a proper tool for voltage stability assessment. Nevertheless, in the sequel, it will be shown that these indices have a major drawback, which is not considered in the literature . To explain this drawback, consider the simple network shown in Figure A, which includes three transmission lines connected in series.…”

“…Nevertheless, in the sequel, it will be shown that these indices have a major drawback, which is not considered in the literature. 35,[48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][68][69][70][71][72][73][74][75][76][77][78][79][80][81][82][83][84] To explain this drawback, consider the simple network shown in Figure 13A, which includes three transmission lines connected in series. In this network, the maximum transferable power is 67 as follows: When P max passes through the transmission corridor, it is expected that the line indices calculated for line 2 (or two other ones) reach to their critical threshold to show the proximity of the operating point to stability boundary.…”

Summary So far, several line stability indices have been introduced and used for evaluating voltage stability status of power systems. The objective of this paper is to propose a comprehensive assessment of these indices and also to propose a modified line stability index to accurately assess the stability status of networks in different situations. To this purpose, the performance of several line indices at different conditions is analyzed. Also, to categorize system states to normal, alert, and emergency, proper thresholds are proposed for these indices. It will be shown that although line indices are able to properly assess the stability of a two‐bus system, they cannot detect the stability status in real networks. Therefore, a modified index has been proposed, which can accurately assess the stability status of power systems. The static and dynamic simulation results performed in the Institute of Electrical and Electronics Engineer (IEEE) 39‐ and 118‐bus test systems verify the performance of the proposed index.

“…In earlier studies, many researchers focus on steady-state [3][4][5][6] or short-term voltage stability [7][8][9][10] separately and did not incorporate the two aspects together to maximise the beneficiary impact of STATCOMs on the power system. Lately, some researchers start to address this issue from both perspectives [11,12]. In [11], the authors propose a multiobjective optimisation model for STATCOM placement.…”
