“…The TOCC [18] is an optimization approach that is applied to the predictive control and improves controller dynamics during fast reference current transients. The term "optimal" means the fastest possible response to a change in the operating point of the VSC when operating with the maximal available magnitude of the output voltage vector.…”

“…PC is a general name for a wide range of control approaches that use an explicit model of the controlled device to predict the behavior of a plant [7][8][9][10][11][12][13][14][15][16][17][18]. Since the electrical machines are relatively well modeled it is possible to use their The PCs are mainly implemented as a discrete control system based on the Digital Signal Processors (DSP) [8].…”

In this chapter, different STATCOM control algorithms will be introduced. The algorithms are derived on the basis of STATCOM mathematical models in the α-β coordinate system and in the synchronously rotating d-q coordinate system. In the first part of the chapter, both mathematical models are derived from the threephase STATCOM model, and the mathematical process is described in detail. In the second part, four different control algorithms are described: d-q control algorithm for balanced and unbalanced conditions, time-optimal current-control algorithm and Proportional-Resonant (PR) multi-loop controller.

“…Meanwhile, time-domain techniques use instantaneous p-q theory [160], synchronous d-q reference frame theorem [161], synchronous detection theorem [120,162], constant power factor algorithm [163], PI controller [156], fuzzy controller [164], hysteresis controller [165], and sliding-mode controller [166]. Methods such as dividing frequency control [167] and extension p-q theorem [168] are implemented to generate the reference signals, which implement the p-q technique. Similarly, the synchronous d-q reference, known as SRF, practices the notch filter method [169] for calculating the voltage and current reference for the synchronously rotating reference frame, as in the case of the DC bus feedback voltage-fed APFs.…”

Abstract:This study summarizes an analytical review on the comparison of three-phase static compensator (STATCOM) and active power filter (APF) inverter topologies and their control schemes using industrial standards and advanced high-power configurations. Transformerless and reduced switch count topologies are the leading technologies in power electronics that aim to reduce system cost and offer the additional benefits of small volumetric size, lightweight and compact structure, and high reliability. A detailed comparison of the topologies, control strategies and implementation structures of grid-connected high-power converters is presented. However, reducing the number of power semiconductor devices, sensors, and control circuits requires complex control strategies. This study focuses on different topological devices, namely, passive filters, shunt and hybrid filters, and STATCOMs, which are typically used for power quality improvement. Additionally, appropriate control schemes, such as sinusoidal pulse width modulation (SPWM) and space vector PWM techniques, are selected. According to recent developments in shunt APF/STATCOM inverters, simulation and experimental results prove the effectiveness of APF/STATCOM systems for harmonic mitigation based on the defined limit in IEEE-519.
