“…Moreover, the bidirectional operation is not possible. Zaidi et al [2] discussed reactive power support using the RE integration grid tie inverter, but harmonic elimination is not achieved. Similarly, the controllers discussed above do not offer PV integration to grid along with the harmonic elimination and ESS charging capability in a single unit.…”

“…Dubey and Santoso [1] investigated PEV charging impacts on the residential distribution network and discussed the associated power quality issues. The study by Zaidi et al [2] has shown that higher power levels for PEV charging in the distribution network demand FACTS devices for power quality improvement. Reactive power support using renewable energy (RE) integration grid tie inverter is also proposed by Zaidi et al [2].…”

With the growing popularity of electrified transportation across the world, there have been extensive reports of research involving plug-in electric vehicles (PEVs), electric vehicle charging facilities (EVCFs) and their integration to the main electric grid, besides sustainable energy resources for powering these vehicles. This study proffers a power factor corrected level-1 DC public green-charging infrastructure accompanied by an integrated control, for electric light motor vehicles, compliant with recently formulated Indian charging standards. Power factor correction of plug-in electric vehicle charging current, solar photo-voltaic grid integration and charging of energy storage system is achieved using control of bidirectional AC/DC converters. A firmware and user interface for multimode off-board DC charging, with green, fast and semi-fast charging modes are investigated. Intelligent control for fast charging is also presented to reduce its pernicious impact on the grid. The simulation and hardware results verify the prime performance objectives of improving the local power quality and renewable energy utilisation with multimode charging, in the Indian context. The effectiveness of the proposed infrastructure is further demonstrated by a simulated use case, where 30 PEVs are randomly charged, in various modes, at this EVCF during busy commute hours. 2 State-of-the-art This section presents the issues, latest research, and standards, both global and in the Indian context in the area of PEV charging infrastructure and its grid integration. 2.1 Power quality issues due to charging equipment In linear circuits, as voltage and currents are sinusoidal, the power quality issue arises from the displacement power factor. In nonlinear circuits, with non-sinusoidal currents, power quality issues arise from both displacement and distortion power factor [11]. Loads that draw non-sinusoidal current from the sinusoidal voltage source cause harmonics. Battery chargers, typically, are equipped with rectifiers at the input stage that cause current harmonics in the distribution system [12, 13]. Generally, lower priced models of chargers do not handle this requirement effectively. Saber et al. [14] propose a PFC scheme based on unidirectional, current-source active rectifier for charging PEVs. An on-board PFC scheme was also discussed in [15], in which the converters in the PEV are controlled to refine the power quality. However, this increases the complexity and weight of the on-board charger.

This study proposes a generalised STATCOM model employing active load and ideal synchronous condenser representation and its related power flow solution. The proposed method considers the effects of DC side voltage, internal switching losses, and operation mode on the power flow problem. To such aim, the proposed model tackles with a tap changing transformer accompanied by a variable conductance at the DC side in order to model the switching losses. This model can also take into account voltage regulation, reactive power control as well as amplitude modulation ratio and practical limitations. It is worth noting that the proposed model can be easily used for power flow studies by applying ordinary changes to the prevalent Newton-Raphson-based power flow methods. The introduced model is applied to two test systems including IEEE 14-Bus system, followed by a discussion on results.

This paper presents an overview of the impact of high penetration of photovoltaic (PV) systems in low-voltage distribution networks (LVDNs). High integration of solar PVs in the LVDNs has severe implications on the system parameters, efficiency, and stability. This paper also introduces the methods that have been driven to overcome these effects to preserve the steady-state conditions in the system during excessive penetration of PV generation units. A comparison between the contributions and shortcomings of the most recent researches for overvoltage mitigation strategies has been driven. Also, it includes comparing different overvoltage mitigation methods to handle the impact of the overvoltage under high penetration of PV units in the LVDNs. Besides, it presents a comparison between overvoltage mitigation methods based on their pros and cons.
