“…For that, an analogy between electrical components and thermal variables have been carried out. In 2014 our group has introduced such approach to simulate superconducting fault current limiters (SFCLs) [28] and it has been used by many research groups [29][30][31][32][33]. Now, based on the same principle, we propose an approach to fast thermal modeling of HTS power cables allowing improved accuracy with respect established thermal equivalent circuits.…”

Due the integration of superconducting technologies into electrical networks around the world, its precise simulations in power grids are increasingly becoming a desirable outcome. Over the years, sophisticated methods have been used to model superconducting power cables and, in this way, predict its behavior under different conditions. Most of the available models, however, are not advisable to be used and embedded in power system simulators. In this manuscript, we focus on the development of a method specifically for modelling superconducting cables in traditional power grid simulators. We start developing the model through a case example, within the basic concepts are introduced and later expanded to general cases. The model also incorporates the transient behavior of the cooling media, which is mandatory for such cables. It has been observed that the proposed model requires less computational effort and is able to deliver accurate results when compared to more advanced methods.

The stability related issues may occur in a power system due to disturbances in generating or loading conditions, especially in the presence of distributed generation (DG) based on renewable energy resources (RERs). This paper proposes a novel strategy for the stability enhancement of a wind power generation system (WPGS) by using a combination of three devices, namely, a power system stabilizer (PSS), resistive superconductor fault current limiter (R-SFCL) and static synchronous compensator (STATCOM). The small signal (SS) stability of the test system is enhanced by selecting the best PSS type from the different types of PSS. An R-SFCL is used for improving the rotor angle and the frequency stability of the test system. Two indices, namely, transient stability index and sum of maximum deviations (SMD) index are introduced for determining the optimal locations of different sized R-SFCLs for increasing the rotor angle stability. The sensitivity index (SI) based on the power change between areas is applied for determining the optimal locations of different sized R-SFCLs for enhancing the frequency stability. Along with rotor angle and frequency stability, LVRT capability improvement of the wind farm using STATCOM is also considered. Finally, the combined effect of R-SFCL and STATCOM on the rotor angle and the frequency stability, for different fault locations, is also investigated for determining the optimal location of an R-SFCL in the presence of STATCOM. The results presented in the paper show that STATCOM affects both the number of feasible locations and the optimal locations that can be selected for different sized R-SFCLs for augmenting the rotor angle and the frequency stability of the system during faults. Moreover, it is pointed out that an optimal combination between the different sizes and the locations of R-SFCLs and STATCOM exists to enhance the overall stability of the test system under fault conditions. INDEX TERMS Resistive Superconductor Fault Current Limiter, Stability Enhancement, STATCOM, LVRT and Wind Energy I. INTRODUCTIONA power system is considered stable if it can maintain an equilibrium state when subjected to physical disturbances. Small-signal (SS) stability describes the ability of a power system to remain in synchronism mode in case of small load variations or decoupled generators. The transient stability deals with the ability of a system to maintain its stability after occurrence of a severe disturbance, i.e., faults. The stability issues may occur in a power system due to a large change in generation or loading conditions. These issues are aggravated due to large scale integration of renewable energy resources (RERs) especially based on wind power generation. Due to intermittent nature of wind power, the transient, frequency and voltage stability may be affected. Moreover, power generated from wind turbines would change the power flow of the system and have an effect
