“…A considerable number of publications have been made on cascaded multilevel converters [31,38,39,41,44,45,48,67]. As shown in Figure 3, good work has been written on VSC [30,35,37,43,52,57,64], PWM [28,46,58,59,60], MMC [40,49,62,63,66,73], software-based [32,47,53,71,72], and load flow models [50,51,54,68,70], as shown in Figure 3. Some papers on multilevel converters [33,56], cascaded multilevel inverters [34,55], multilevel inverters [69], VSI [36], hexagram converters [42], and novel techniques [29,61,65] have been observed.…”

The Static synchronous compensator (STATCOM) is a renowned FACTS (flexible alternating current transmission system) device used in power grids to cope with protean conditions. This article provides a comprehensive bibliographic review of various aspects of STATCOM developed over the last 16 years. The paper includes a detailed study presenting different models, test systems, and results of various researches. The study covers the modelling, control technology, stability, optimal location, applications, and installation of STATCOM. The modelling of STATCOM is diverse and include various models such as voltage source converters, software-based models, load flow models, pulse width modulation, and modular multilevel converters. The control technology includes a PI/PID controller, fuzzy-based, feedback controller, model predictive controller, sliding mode controller, and miscellaneous controller based on different schemes, algorithms, and controllers. In studying the stability analysis, all stability aspects such as steady-state stability, dynamic stability, and transient stability are considered for the stability analysis. The genetic algorithm, heuristic algorithm, probabilistic technique and branch and bound approach are mainly used for the optimal placement of STATCOM as described in the available research paper. Various applications of STATCOM in power system are identified such as optimal power flow, voltage stability, voltage fluctuation mitigation, fault analysis and total harmonic distortion. This paper, also mentions the current installation of STATCOM is also mentioned with their different locations such as China (2018), and Canada (2019). The current functions of STATCOM still have many limitations. So there is still a lot of room for improvement. This paper will help the researcher finding the reference of a particular topic of interest in different aspects of STATCOM. The finding of different sections of the paper can help the researchers to develop new ideas and work on different prospective of the device.

“…It is worth noting that since the virtual bus j is only connected to bus i, then derivative terms of P and Q of all buses expect for bus i are equal to zero. By excluding the row related to injected reactive power and the column related to voltage magnitude, the modified version of (4) and (5) under the voltage control mode are obtained as (7) and (8), respectively. In comparison with (4), it can be concluded that the proposed approach has just led to the changes in equations associated to the active and reactive powers of bus i…”

“…In contrast to the LCC-HVDC transmission systems, the VSC-HVDC system uses the voltage source converters (VSCs). If the DC side of VSC is equipped with the active power energy source, generation and absorption of both active and reactive powers, can be provided [6,7]. To exchange the reactive power with the AC grid, the pulse width modulation (PWM) shifts the output current to the lead or lag the terminal voltage based on the system requirements.…”

This study presents a generalised representation of voltage source converter (VSC) based high voltage direct current (HVDC) systems appropriate for power flow studies using the Newton-Raphson method. To reach this aim, the active loads and ideal synchronous machines are employed in order to incorporate both converter losses and power balance, respectively. Also, considering different aspects of computer implementation, the proposed solution method uses the conventional Newton-Raphson method. The proposed representation considers practical restrictions, switching and conduction losses of semiconductors, and different control strategies for VSC-HVDC stations. Moreover, the proposed generalised representation of VSC-HVDC systems can be easily extended to incorporate the multi-terminal VSC-HVDC grids in an efficient manner. To investigate the application of the proposed representation for VSC-HVDC systems and load flow solution, three test systems including the standard IEEE 30 bus and IEEE two area RTS-96 networks are used and discussion on results is provided. Results show that the proposed algorithm is able to solve AC-DC power flow problems very efficiently with considerably less time in comparison to other existing algorithms.

With the high penetration of the power electronic loads in the grid, the stability of static synchronous compensator (STATCOM) devices is greatly challenged. However, the conventional control methods for the modular multilevel converter (MMC) based STATCOM only consider the stability with small signal disturbances. This paper proposes a novel dual-layer back-stepping control (BSC) for the MMC based STATCOM. In the first layer, the BSC aims to regulate the sum of the capacitor energy and the reactive output current. In the second layer, the BSC aims to control the circulating current. Therefore, the proposed method possesses a fast dynamic response and accurate tracking with the Lyapunov stability of the MMC based STATCOM. Compared with the arm-controlbased back-stepping control for MMC based inverters, the proposed method has a simplified structure and a reduced computation burden. In addition, the proposed method realizes the decoupled control between the output current and the circulating current. The simulation and experimental results verify the effectiveness of the proposed method. In addition, its robustness towards different circuit parameters and the operation ability under unbalanced grid fault is also verified.
