“…In the realm of DC microgrid control, FCS MPC has emerged as a preferred approach to address the limitations of conventional vector control strategies, such as complex PI parameter tuning and multiobjective optimization [21], [22]. This method not only enhances system operation during grid-connected scenarios but also proven effective in islanding mode by anticipating voltage responses for potential switching states within each sample period.…”

In pursuit of sustainable transportation, green energy sources (GES) are taking center stage, propelling traction vehicles like tramways and trolleybuses towards a zero-emission future. Solar is the most prominent source among the available renewable sources and also for the transport system applications. To utilize photovoltaic (PV) source effectively, model predictive controller-based PV maximum power tracking algorithm is used to identify the PV parameters. Equipped with the smart energy storage system (SESS), light traction vehicles rely on the efficiency and reliability of brushless DC (BLDC) motors for smooth operation. However, BLDC motors operate at high voltages, which requires them to be connected to high voltage microgrids. Bridging the gap between ESS/SESS and the high-voltage microgrid with traditional DC-DC boost converters incurs efficiency losses and component stress. This paper tackles high-voltage needs in microgrids through innovative, efficient DC-DC boost converter designs. An innovative finite-control-set based model-predictive control (FCS MPC) controller tackles clean energy harnessing from PV and grid stability in traction applications, enabling optimized power sharing within microgrid constraints.

“…In power generation, the efficiency of the system is significantly influenced by the converter's switching frequency, as a high switching frequency leads to increased losses. Therefore, in order to overcome this problem and achieve a low switching frequency, an improved MPC with a two-step prediction horizon (N=2) is proposed in [30,31]. Whenever two steps are considered for the prediction, two voltage vectors are evaluated.…”

This paper presents a hierarchical wireless control scheme for parallel distributed generation (DG) units in islanded AC microgrids. The proposed control scheme is divided into primary and secondary control layers. The primary control layer includes an improved finite set-model predictive control (FS-MPC) with a dualobjective cost function based on the proposed droop approach. The benefit of the proposed droop approach is the ability to generate the reference voltage without any amplitude deviation, unlike the conventional droop technique, which may cause deviations. Furthermore, double virtual impedances are proposed, with the first one being used to reduce the effects of feeders' mismatched impedance, while the second one is used to increase the output impedance resistance, leading to enhanced accuracy of active and reactive power sharing among DG units. The secondary control layer helps to establish global controllability by keeping the frequency and amplitude voltage of the AC bus at their nominal values. The simulation results show that the proposed control is capable of ensuring appropriate power sharing among parallel DG units and achieving voltage quality at the AC bus under different load conditions.

The integration of power electronics-based generation has increased in the medium voltage (MV) level of the distribution networks, nowadays. It is obvious that the contribution level of this type of source is providing a limited fault current level according to the thermal and fault ride-through capability of power electronic converters. Therefore, the fault current level in the grid-connected and islanded mode of the microgrid is different and the protection scheme is required to be reviewed. In this regard, converters' responses contribute to the stability of the microgrid in the case of abnormal conditions. This paper has investigated the effect of power electronic converters and their controllers in future microgrids with the high penetration level of power electronic-based generation. A distribution management system has been designed to address the issues and challenges of faulty conditions and a voltage ridethrough technique has been proposed. The simulation results of an MV distribution network demonstrate the fault current level of the future microgrid in abnormal conditions. The proper protection strategy is designed to detect any type of short circuit fault current as well as avoidance of damage to the integrated PEC-based generations.
