“…A typical study of EMR is the railway power conditioner (RPC). Much research on RPCs has been conducted [20][21][39][40] ; hence, this paper does not re-prove the experiment data. Therefore, the experiment mainly focused on NCBR.…”

“…Recently, harmonics and reactive power compensation have been optimized from traditional fixed capacitors and passive filters to active power filters [14] and dynamic var compensators [15][16][17][18] . Currently, RPC [20][21] is proposed to balance the current of the RTPS from the perspective of energy movement and can optimize the three-phase unbalanced current and negative sequence current.…”

“…Because of the power quality problems caused by the locomotive, such as voltage harmonics and voltage fluctuations [9][10][11][12][13] , the different phases of RTPSs and REDSs make it difficult to obtain the REDS power supply from RTPS via simple conversion. An active power filter (APF) [14] , static var compensator (SVC) [15] , thyristor control reactor (TCR) [16] , static var generator (SVG) [17][18] , dynamic voltage regulator (DVR) [19] , railway power conditioner (RPC) [20][21] , CO-phase power supply (CO-P PS) [22][23][24][25][26] , and other solutions, are constantly being tried and applied in RPS. However, each only improves a certain function, from the perspective of a single device, or improves the performance of a specific aspect.…”

Railway power system is an inseparable part of the power system, therefore, the intelligent architecture of the railway power system should also be focused on. The unique power supply characteristics of the railway power system are analyzed and integrated railway smart grid architecture based on energy routers is proposed. Importantly, three corresponding resilient mode control methods are suggested for the proposed architecture. In the fourth section, a simulation model corresponding to the resilient control mode is built and the simulation results prove the feasibility of the proposed control mode. Equally, for the novel network-connected backbone router (NCBR), a 1 000 kVA, 27.5/10 kV NCBR engineering prototype is used to prove its effectiveness in practical applications. Finally, a differentiation analysis is given, followed by conclusions regarding the traditional power system and proposed system.

“…The switching frequency of the IGBT-based high-rated power converters is limited to 1.5 kHz [14]. On the other hand, the minimum frequency used in a similar research paper is 500 Hz [33][34][35]. For this purpose, the primary acceptable range for the switching frequency of HBRPC is selected as 500 ≤ f SW ≤ 1500 Hz.…”

AC electrified railway system is a huge single-phase load, which causes significant power quality (PQ) problems to the upstream power grid. Active railway PQ conditioners (ARPQC) have been introduced to overcome the PQ problems. One of the most important complications of the ARPQCs is its high VA rating which entails significant escalation in the price of the conditioner. To mitigate the rating of the ARPQC, a hybrid configuration including an asymmetric balancing traction transformer and a half-bridge railway PQ conditioner (HBRPC) is proposed in this study. The predictive deadbeat current control with low computational burden and fast dynamic response is used to optimise the performance of the HBRPC. Additionally, a PI adaptive gain controller is proposed for DC-link voltage stabilisation, which minimises the negative impact of the voltage control on the current control stage. The feasibility and functionality of the proposed scheme is validated via simulation and experimental results.

“…The damping methods are used to enhance the performance of PR and PI controllers by reduction the resonance effect, in another hand, these methods add extra cost like extra power in passive damping method and extra number of sensors in active damping method. Another non-linear methods are used to enhance the performance of GCI with filter, such as predictive control [13], [14], deadbeat control [15], [16] slide model control [17], [18], adaptive control [19], [20], and passivity based control with wind system [21], railway systems [22], [23], energy storage systems [24], [25], islanded AC microgrid [26] and GCI systems [27]− [34]. The passivity-based control (PBC) strategy has simple modeling process and better performance against parameters variations with different types of filters.…”

This paper presents photovoltaic three-phase grid-connected inverter with an inductor-capacitor-inductor (LCL)-filter. For robustness against variation of filter parameters and external disturbance, the passivity-based control (PBC) method has been adopted. In this method, there are two interactively coupled feedforward terms and three damping gains in the control loops which are designed to limit the steady state error of grid current. Boost converter with P&O maximum power point tracker (MPPT) is used for each photovoltaic (PV) string to extract maximum power and to raise the PV voltage to a value suitable for the grid-connected inverter. The outputs of all boost converters are connected in parallel and controlled to fixed reference voltage using proportional-integral (PI) controller to make the direct-current (DC) link voltage robust against variations in sun radiation intensity and system parameters change. The suggested system is analyzed, designed and simulated using PSIM program. 1 kW, 2kW, and 3kW PV systems connected to grid of 220V/50Hz are tested and the results show the validity of the suggested grid-connected PV systems and robustness against filter parameters variation.
