“…where 𝑖 𝑑𝑐 is the DC bus current, 𝑖 𝑐𝑎𝑝 is the split-capacitors current and 𝐶 = 𝐶 𝑢𝑝 /2 = 𝐶 𝑙𝑜𝑤 /2 whereas  𝑔 is the grid angular frequency. By substituting (13) into (20), and the resulting ( 18) -( 20) into (17) while assuming an average value for the grid current and the duty cycle, the small signal model that links up the dc bus voltage with the grid current is found as: (21) the same assumption as in the inner loop, i.e., 𝑉 𝑔𝑟𝑖𝑑 (𝑠) = 0, the transfer function 𝐻 𝑉 (𝑠) for the outer voltage loop is expressed as: (22) Bearing in mind that this outer loop deals with the bus voltage that is a DC quantity, thus a classical PI controller has been used. The transfer function 𝐻 𝐶 𝑉 (𝑠) of this voltage controller is given by [4]: (23) By programming the transfer functions of the plants ( 15), (22) as well as the compensators ( 16), (23) in MATLAB code and using the single-input single-output (SISO) design tool, the gains of the controllers have been accurately tuned until obtaining a good response [4], [16], [32].…”

“…In spite of this requirement, three-level [9], five-level [10] and even seven-level [11] NPC/ANPC converters have been successfully applied in shunt active power filters (SAPF) for power quality improvement. In applications where these converters are further series-connected with an EV battery charger, the power transfer between the battery, the grid and the load can be controlled, thus giving rise to three possible operation modes, i.e., grid-to-vehicle (G2V), vehicle-to-grid (V2G) and vehicle-to-home (V2H) [12], [13]. The disregard of the splitcapacitors voltage imbalance in the NPC/ANPC topologies results in a distorted output voltage from the converter [14].…”

This paper presents the performance evaluation of a proposed single-phase bidirectional active neutral-point-clamped (ANPC) five-level converter (5LC) for active filtering in grid-to-vehicle (G2V), vehicle-to-grid (V2G) and vehicle-to-home (V2H) applications. In the system, the 5LC is series-connected with an electric vehicle battery charger based on a dual active half-bridge DC-DC converter (DAHBC). A cascaded strategy with a proportional-resonant compensator controls the 5LC whereas the DAHBC is controlled by a single phase-shift technique. A performance comparison is carried out for the proposed topology versus three NPC/ANPC 5L converters found in literature with similar topologies. The simulation results obtained in MATLAB-SimPowerSystems along with the experimental results obtained from a laboratory prototype validate the following: a) the first two literature topologies have the highest efficiencies, but they are incapable of balancing the voltage of the split-capacitors what increases the total harmonic distortion of both the grid current in the G2V/V2G modes and the 5LC output voltage in the V2H mode while producing a sluggish transient response, b) the 3rd literature topology like the proposed one properly balance the capacitors voltage and achieve a faster dynamics, but at the expense of an efficiency reduction, and c) unlike the former topology that continuously applies a natural but wasting unfedback voltage balancing strategy, the proposed one that includes a closed-loop control allows achieving an ANPC 5LC with a superior performance featured by a higher efficiency, a reduced switches stress, a flatter power losses distribution and a better power quality improving under the three modes of operation.

“…However, there is a lack of discussion on voltage unbalance particularly in regard to the active filtering operation. Other studies [35,36] have proposed a bidirectional grid interface capable of both acting as an active power filter and battery, thereby providing correction of harmonic currents and compensating reactive power in single-phase electricity networks.…”

“…The power structure chosen to accomplish the integration of an electrical vehicle with the electric grid is arranged in a dual-stage configuration and composed of five parts. This structure is the most commonly employed [12] and counts with two dedicated power processors, similar to the structure employed in [10,13,14]. The parts are:…”

The number of electric vehicles is expected to increase exponentially in the next decade. This represents a huge potential for grid support, such as energy storage in their batteries, with advantages for grid operators and for customers. For this purpose, flexible power interfaces are required. This paper presents a simulation of a bidirectional singlephase power interface between an electric vehicle battery and the grid. The proposed system is fully simulated and counts with features such as vehicle-to-grid, vehicle-to-home and grid-to-vehicle. All power flow and the controllers for these modes of operation are described in detail. The simulation was developed in a Software-in-the-Loop scheme to facilitate a future physical implementation with a Hardware-in-the-Loop platform. The proposed system was extensively tested via simulation, the results proving the system is stable, able to change operation modes smoothly and definition of the exchanged active and reactive powers.
