“…The authors of [145] proposed a general methodology for the improvement of steady-state voltage stability using FACTS devices in an IEEE 39-bus test system environment. A. Rathi et al offered a different Distributed Flexible AC Transmission System (D-FACTS), for controlling system voltage by examining sensitivities of voltage magnitudes with respect to variations in line impedances [146]. Figure 1 demonstrates types of FACTS devices, and Table 2 summarizes some important FACTS devices used for voltage stability improvement with special findings asserted by several researchers.…”

The fast growth of the world’s energy demand in the modernized world has stirred many countries around the globe to focus on power generation by abundantly available renewable energy resources. Among them, wind energy has attained significant attention owing to its environment-friendly nature along with other fabulous advantages. However, wind-integrated power systems experience numerous voltage instability complexities due to the sporadic nature of wind. This paper comprehensively reviews the problems of voltage instability in wind-integrated power systems, its causes, consequences, improvement techniques, and implication of grid codes to keep the operation of the network secure. Thorough understanding of the underlying issues related to voltage instability is necessary for the development of effective mitigation techniques in order to facilitate wind integration into power systems. Therefore, this review delves into the origin and consequences of voltage instability, emphasizing its adverse impacts on the performance and reliability of power systems. Moreover, it sheds light on the challenges of integrating wind energy with existing grids. This manuscript provides a comprehensive overview of the essential features required for critical analysis through a detailed examination of Voltage Stability Indices (VSIs). To address voltage stability issues in wind-integrated power systems, this review examines diverse techniques proposed by researchers, encompassing the tools utilized for assessment and mitigation. Therefore, in the field of power system operation and renewable energy integration, this manuscript serves as a valuable resource for researchers by comprehensively addressing the complexities and challenges associated with voltage instability in wind-integrated power systems.

“…The objective function is often defined in terms of maximising voltage stability and minimising voltage deviation, power losses or costs. Voltage stability can be either calculated using PV studies [8] or CPF [11], or estimated, using eigenvalues-based methods [6], index-based methods ( [9,14]), modal analysis techniques [15] or trajectory sensitivity analysis [16]. Alternatively, some authors establish an economical scope on their studies by optimizing generation costs [17], fuel costs [18], operation costs [19] or the NPC [20].…”

A FACTS Devices Allocation Procedure Attending to Load Share

Power system stability is a topic which is attracting considerable interest due to the increase of both electrical demand and distributed variable generation. Since Flexible AC Transmission Systems (FACTS) devices are an increasingly widespread solution to these issues, it is important to study how their allocation procedure should be done. This paper seeks to assess the influence of load share in FACTS devices allocation. Despite this interest, researchers, as well as system planners, have mainly focused on studying single power system configuration rather than using a wider approach. Keeping this in mind, we have iteratively created several load share scenarios based on an IEEE 14-bus test system. Subsequently, we have applied an heuristic procedure in order to demonstrate how load share may affect the results of the FACTS devices allocation procedure. Additionally, we have compared results from two different objective functions so as to evaluate our proposal. Finally, we have proposed a solution to FACTS allocation which takes load share into account. Our tests have revealed that, depending on the distribution of load within the power system, the optimal location for a FACTS device may change. Furthermore, we have also found some discrepancies and similarities between results from distinct objective functions.
