“…6 Figure 2 shows types of SST.When non-linear loads and power electronics equipment are used excessively at the (PCC), harmonic currents are generated, which reduce the quality of the electrical power. 7 The DC-link capacitor, located on the front of the VSI, is used to manage reactive power for the grid. 8 The most commonly used controller in business is the proportional-integral-derivative (PID) controller, but it only performs properly when its settings are correctly tuned.While conventional approaches like Ziegler-Nichols and pole placement have been employed historically for achieving this objective, there has been a growing trend in the adoption of state-of-the-art techniques such as heuristic optimization algorithms in recent times.…”

Future electric power distribution will heavily rely on solid-state transformers (SST). Typically, traction and transportation systems use the SST. It can be used for various purposes, though. For instance, the current demand for electric vehicles (EVs) requires the service provider to enhance the infrastructure, such as the number of highpower EV charging stations in urban areas. SST-based charging stations are one design option for high-power charging stations, and they can be linked to the distribution network. The article suggested a novel design for optimizing PI gains using the chaotic GWO algorithm for DC link voltage regulation and a reduction in THD using the SST instead of a shunt active filter in SST-based conductive charging of EVs. Second, the SST is used in place of a series active filter to mitigate voltage sag, swell, and PF correction when faults or abrupt changes in load occur in the AC system. Thirdly, for safety reasons, the SST-based charging of EVs uses a 4P DC breaker. Finally, using the SIMULINK/MATLAB platform, all the cases were simulated, and the results were displayed.

“…In [30], the authors have investigated the execution of D-STATCOM for reactive power compensation required by doubly-fed wind farm linked to the grid. The power quality concerns alleviated by D-STATCOM in [31] employing PR control and comb filter during unbalanced and non-linear scenarios. Though, the linear control strategies have major limitations such as tuning of control constraints, inadequate transient response [32], and deficient reference tracking in the situation of challenging a significant error [33].…”

Analysis of Fractional Order Sliding Mode Control in a D-STATCOM Integrated Power Distribution System

At present, the disturbances like the voltage fluctuations, resulting from the grid's complexities and unbalanced load conditions, create severe power quality concerns like total harmonic distortion (THD) and voltage unbalance factor (VUF) of the grid voltage. Though the custom power devices such as distribution-static compensators (D-STATCOMs) improve these power quality concerns, however, the accompanying controller plays the substantial role. Therefore, this paper proposes a fractional-order sliding mode control (FOSMC) for a D-STATCOM to compensate the low power distribution system by injecting/absorbing a specific extent of the reactive power under disturbances. FOSMC is a non-linear robust control in which the sliding surface is designed by using the Riemann-Liouville (RL) function and the chattering phenomenon is minimized by using the exponential reaching law. The stability of FOSMC is evidenced by employing the Lyapunov stability criteria. Moreover, the performance of the proposed FOSMC is further accessed while doing its parametric variations. The complete system is demonstrated with a model of 400V, 180kVA radial distributor along with D-STATCOM under two test scenarios in MATLAB/Simulink environment. The results of the proposed controller are compared with the fixed frequency sliding mode control (FFSMC) and conventional proportional-integral (PI) control. The results validate the superiority of the proposed controller in terms of rapid tracking, fast convergence, and overall damping with very low THD and VUF.
