“…It has the capacity to regulate numerous parameters autonomously, and therefore, it may be described as a combination of STATCOM and SSSC (static synchronous series compensator). In [78], the authors proposed and analyzed a novel and unique controller for the UPFC's series and shunt converters. The operational system of UPFC presented in the journal clearly shows that it is capable of controlling the flow of the paper.…”

Super smart grids (SSGs) are a wide area transmission network that mainly uses renewable energy resources (RERs), contributing to the reduction of greenhouse gas (GHGs) emissions and supporting the power infrastructure of multiple countries. The SSGs comprise two-way communication between the loads and sources of different countries, and these loads can be mostly served with numerous types of RERs tied with the grids. The RERs will play a pivotal role in the development of future grids and the generation of electricity. However, the main challenge to tackle in these RERs is that they are intermittent in nature. Due to intermittency in these RERs, transient stability issues have become one of the critical research challenges in SSGs. These stability issues are escalated and become more difficult to handle if a network is vulnerable to an arising of different kinds of faults. To address these problems, multiple approaches to enhance transient stability already exist in the current literature. After reviewing the literature, flexible alternating current transmission systems (FACTS) devices proved more promising in improving transient stability. Among FACTSdevices, UPFC is a versatile FACTS device, which provides complete stability to power system networks in the form of series and shunt compensations. Considering this scenario, a hypothetical network for SSGs is designed in this research work based on the interconnection between two countries, i.e., Denmark and Norway, to address the transient stability issues in SSGs. The complete probabilistic model of the system is also designed to enhance the stability of the system. The results clearly showed that the insertion of UPFC is an effective technique to enhance the transient stability and resilience of the power system networks as compared to other purposed techniques in the literature. The main contribution of this paper is that extensive simulation studies employing accurate RERs models are used to analyze and investigate various problems arising due to the integration of many clusters of RERs in SSGs.

In recent years, the inclusion of flexible AC transmission systems (FACTS)-based compensating devices such as a thyristor-controlled series capacitor (TCSC) and a unified power flow controller (UPFC) has been increased in high-voltage power transmission systems due to numerous technical and economical benefits. However, the operation of such FACTS devices introduces harmonics and non-linearity in power system and causes fast changes in line impedance. As a result, the most widely used fixed impedance setting based distance relaying scheme finds limitation in protecting such compensated lines. Significant research has been carried out in recent years to develop new algorithms and methods to address the problem. This paper presents a comprehensive review of recent developments in the protection of TCSC/UPFC compensated high-voltage transmission lines. The relative merits and demerits of each of the available methods are also presented for comparison. Prior to detail review, the impact of TCSC/UPFC on distance protection is evaluated by using data generated through EMTDC/ PSCAD on a 400 kV two-bus test power system. This study can be useful to both academic researchers and practicing engineers to gain insight on the protection of FACTS compensated transmission lines and for further development of newer algorithms. 2 FACTS compensated high-voltage transmission lines: protection challenges The basic configuration and the different operating modes of TCSC and UPFC controllers and their impacts on the distance protection are well documented in [10-16], respectively. However, for the sake of completeness, in this section, the impact of TCSC/UPFC compensated transmission lines on the performance of distance relay is evaluated by using data simulated through EMTDC/ PSCAD on a 400 kV test power system.

“…A transient stability enhancement in a power system with UPFC has been investigated by POD and PID controllers [10]. In [11], the Control Lyapunov Function (CLF) and Power Oscillation Damping (POD) are utilized to dampen the fluctuations. The POD controller of the UPFC is proposed for damping fluctuations due to disturbances in an aggregated wind farm [12].…”

This paper offers novel non‐linear control of a doubly fed induction generator (DFIG) and unified power flow controller (UPFC) for transient stability increment with transient energy function (TEF) and sliding mode observer in a power system. First, the TEF technique is considered for the damping control in a power system with a synchronous generator (SG), DFIG, and UPFC, and then the controller time‐derivative signals are estimated by a second‐order sliding mode observer. The importance of the issue is in the employ of a complete UPFC model. Also, a one‐axis model is used for DFIG that is similar to the SG model. Another characteristic of the novel non‐linear technique is robust versus system topology changes and variable time delay of the control signals. To evaluate the performance of the novel non‐linear control method for increment transient stability, simulation studies are performed on a two‐machine connected to an infinite bus (TMIB), the IEEE 9‐bus, and the New England Standard 39‐bus power system. The results determine that the novel non‐linear control method decreases the first swing of fluctuations admissibly and enhancement stability margins considerably.
