“…The discrete time digital implementation of the SOGI-based frequency adaptive PR controllers is based on a twointegrator scheme with backwards Euler integration for both integrators, accounting for the inherent one-step time delay of the digital signal processing [16], [34]. However, the SOGI-QSGs are implemented according to the state-space approach presented in [35].…”

This paper presents a single-phase Virtual Synchronous Machine (VSM) and its possible application for providing Vehicle-to-Grid (V2G) services from domestic battery chargers of Electric Vehicles (EVs). In a VSM, the power converter is controlled to emulate the inertia and the damping effect of a synchronous machine. Thus, a VSM-based EV charger can contribute to the spinning reserve and the frequency regulation of the power system. In case of grid outages, the VSM can seamlessly establish an islanded grid and supply local loads from the battery onboard the EV. In order to avoid the influence on the virtual inertia from power oscillations associated with a single phase circuit, the proposed control scheme relies on a virtual two-phase system for calculating active and reactive powers. The proposed VSM implementation is described in detail and its dynamic performances in grid-connected as well as stand-alone operation are demonstrated by numerical simulations and by laboratory experiments.

“…The main advantage of this platform is due to its 32-bits architecture, suitable for programming floating point, allowing greater accuracy and speed in the estimation of frequency. Considering that the control system proposed in section II must be implemented, it is necessary to use the Euler method [14]- [16] to discretize the equations of state.…”

This paper presents a feasible implementation of a single phase inverter prototype via a Highly Efficient and Reliable Inverter Concept (HERIC) topology, which is connected to the grid through a phase and frequency synchronization system by means of a Second Order Generalized Integrator -Frequency Locked Loop (SOGI-FLL). The chosen topology for the inverter design -unlike a full H-bridge (FB) inverterincorporates two transistors in the output aimed at preventing reactive power transfer between the output filter and input capacitor when zero-crossing. Furthermore, proposed inverter implementation presents low leakage currents, and increases HERIC system efficiency. Moreover, the SOGI-FLL chosen for connecting the HERIC inverter to the grid provides -even under harmonic distortion-a fast and accurate frequency tracking. The prototype implementation can be divided into two parts: First, the power inverter HERIC is implemented, which holds four transistors MOSFET IRF730 (400V-10A) in a FB topology, as well as two IGBT transistors GP10NC60KD (600V-10A). In addition, in order to protect all the devices and ensure a well transistor conmmuation, four diodes type SF54 (200V-5A) are located between emisor and collector from all transistors. Second, the synchronization system is implemented on an Arduino Due digital platform.Index Terms-Power system interconnection, HERIC inverter, Frequency locked loop , Second order generalized integrator.

Abstract. In this paper, a review of Phase Locked Loop (PLL) algorithms and symmetrical component extraction methods intended for grid-connected power electronic converters are presented. Proposed classification is based on voltage representation in three coordinates: natural (abc), stationary (αβ) and rotating coordinates (dq). The three selected algorithms are described in details: Dual Second Order Generalized Integrator (DSOGI-PLL), Dual Virtual Flux -both in stationary coordinates. The third one, in rotating dq coordinates, is Dual Synchronous Reference Frame PLL (DSRF-PLL). A comparison of PLL algorithms is presented. Also, selected experimental results are given to verify practical application of discussed algorithms.
