A review on power quality issues in electric vehicle interfaced distribution system and mitigation techniques

Abstract

Electric vehicles (EV) penetration in the distribution systems is evident and intended to grow day by day. Power quality issues pop up in the distribution system with an increase in EV penetration. Distribution networks need to consider the power quality issues developed due to the penetration of EVs for planning and designing the system. The power quality issues, including voltage imbalance, total harmonic distortion, distribution transformer failure, and related issues, are anticipated due to EV penetration in distribution systems. Detailed review of power quality issues and mitigation techniques are detailed in this paper. Discussion on the effect of these power quality issues on the distribution systems and corresponding mitigation measures are detailed. Power quality impact mitigation techniques have been discussed recently, which exploits the bidirectional power flow of vehicle to grid vehicle to grid (V2G) and grid to vehicle grid-to-vehicle (G2V). Methods and methodologies that mitigate power quality problems in the EV penetrated distribution system is discussed. Bidirectional power flow during EV charging and discharging and power quality issues in this topology is detailed in this review paper. A discussion on future trends and different possible future research paradigms is discussed as the review's conclusion.

Inter-connected AC/DC HMGS power management with 3-phase and 1-phase ILC

“…The scaling values for θ1=0.3, θ2=0.007, θ3=10 is predefined to set the controller. In case of overload demand on AC load bus it will impact on the AC generation power grid given in (7).…”

“…Electric vehicle is the present trend attracting researchers for integrating to MG, nano grid (NG) for two-way power flow through energy storage system (ESS), the power quality problems associate to grid are discussed with optimal solution by connecting filter and restorer [6]. A review paper discusses the power quality issues in bidirectional power flow in electric vehicle to grid [7]. To reduce the total harmonic distortion (THD) in a single-phase inverter a control technique confined band variable switching frequency pulse width modulation (CB-VSFPWM) is designed [8].…”

Mitigation of harmonic distortions in third rail electrical systems

“…The abundant usage of rectifiers in the third rail systems can cause severe harmonic distortion [7]- [9]. Harmonic distortions give rise to many technical issues including degradation of transformers [10], [11] and electric motors [12], low power factor, malfunction of protective relays, increase of power losses, resonance [13], [14], and interference to communication devices [15]. For example, the use of 12-pulse rectifiers in the third rail system has generated a significant amount of 11 th and 13 th order harmonics, resulting in significant harmonic pollution to the rail system [16].…”
