The Malaysian Government has set an ambitious target to achieve a higher penetration of Renewable Energy (RE) in the Malaysian energy mix. To date, Malaysia has approximately 2% of its energy coming from RE generation sources compared to the total generation mix and targets achieving 20% penetration by 2025. The current energy mix for Malaysia power generation is mainly provided by natural gas and coal. The discussion will cover the traditional sources of generation including natural gas, coal and big hydro stations. In addition, the paper will cover in depth the potential of RE in the country, challenges, and opportunities in this sector. This study can give an initial evaluation of the Malaysian energy industry, especially for RE and can initiate further research and development in this area in order to support the Government target to achieve RE target of 20% by 2025.

“…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.
