“…Thus, the required rating of the parallel-connected STATCOM is much higher than those of the added AFs in Figures 1 and 2. In [14], the required rating of the STATCOM is 80% as compared to the rating of the three-phase load. Using a large capacity, the STATCOM results in a high-cost hybrid SVC.…”

This paper proposes a new hybrid static VAR compensator (SVC) with a series active filter (AF). The proposed hybrid SVC consists of a series AF and SVC. The series AF, which is connected in series to phase-leading capacitors in the SVC, performs for a resistor for source-side harmonic currents. A sinusoidal source current with a unity power factor is obtained with the series AF, although the thyristor-controlled reactor generates harmonic currents. A digital computer simulation was implemented to confirm the validity and high practicability of the proposed hybrid SVC using PSIM software. The simulation results demonstrate that sinusoidal source currents with a unity power factor are achieved with the proposed hybrid SVC.

“…In a special report, the shunt compensation devices, particularly the SVCs, are shown to have the largest market share among other FACTS devices with 77%, in implementation around the world being $1.067 billion by 2018, with a compound annual growth rate of 7.11% since 2011. Moreover, around 5% of the SVC installations in the world is in the Kingdom of Saudi Arabia (KSA), particularly for voltage regulation, due to the long overhead line implementations, scattered load centers, and high local annual demand growth, which has been in the range of 6% to 8% since 2003 to reach more than 50 GW in 2014.…”

Summary Voltage regulation at weak distribution networks and feeders imposes several challenges. The degree of complexities of the overall design and implementation is network and site dependent. In this paper, design and implementation of a thyristor controlled reactor–based static VAr compensator (SVC) system to enhance voltage regulation and avoid voltage instability are presented and discussed. The SVC system is installed for an extremely weak distribution network with long feeders in a remote area in the Kingdom of Saudi Arabia. This work is the first implementation of an SVC system in the utility's distribution network in Kingdom of Saudi Arabia. Principles of operation, overall design assessment, and protection modifications in the installation area are described. Power stage and digital control system are custom designed according to the specific network and operation requirements. The overall system is examined under steady‐state and dynamic conditions. Power system at the corresponding area with/without the compensator is simulated using PSCAD/EMTDC software. Field test results are also obtained, and the performance of the system is discussed along with the design considerations required for such installations. The various technical discussions presented in this paper highlight several practical considerations and practices that are valid in similar installations for extremely weak distribution networks around the world.

The article gives an overall description of electric transmission systems and the current challenges and changes these systems are facing. Changes are driven by both new commercial and political environment as well as technology changes. This article focuses on the technical aspects that are indirectly driven by the other aspects. This article describes how different technical solutions can be used to manage and mitigate challenges. This covers both HVDC (high voltage direct current) solutions and a number of FACTS (flexible AC transmission system) solutions. Finally, some reflections on the future of electric transmission system are given.
