“…Another topology involves the use of a single-phase inverter bridge, with energy storage elements connected on its DC side [68][69][70]76] or without storage such in [77]. A more complex structure, named Decoupled Voltage and Frequency Controller (DVFC) [64,67], integrates both the inverter bridge and the ELC.…”

“…The authors of [34] consider that the output power of the generator is influenced by two parameters: the phase belt width of the main winding α and maximum output power k. In this regard, numerical analysis is performed for various values of α and k, showing results for the capacitive component of the forward rotating field and resistive load current. In case of a 2.2kW SPIG, the Finite element method is used to highlight the magnetic parameters such as flux linkage, current/flux density and the magnetomotive force (MMF) drop along the contour [76].…”

The use of induction generators for electricity production in small power isolated systems represents the topic for a wide research area. As in such topologies single-phase consumers are predominant, besides three-phase induction generators with adequate balancing circuits, single-phase induction generators qualify as a reliable alternative. In the last 38 years, a significant number of research papers have tackled the problems related to the autonomous operation of single-phase induction generators (SPIGs) such as determining excitation capacitors values and their optimal arrangement, ensuring stable operation in terms of voltage and frequency balancing under varying loads and finally enhancing the quality of the energy delivered to the isolated single-phase consumers. While in case of simple topologies the operation of SPIGs is mainly investigated for fundamental electric parameters dependence with loading, excitation capacitance and speed, the use of power electronics based converters ensures stable operation over a wide range of varying/non-linear loads. This paper presents a comprehensive overview of the literature dedicated to SPIGs, focusing on several significant aspects such as main topologies, modeling, steadystate analysis and performance investigations.

SummaryThis work focuses on a novel single‐phase complex band‐pass filter‐based frequency‐locked loop (1ϕ‐CBF‐FLL) control for a grid‐tied solar photovoltaic array (SPVA)‐based energy generating system. Among the novel characteristics of this 1ϕ‐CBF‐FLL control algorithm are as follows: (1) It offers a quick convergence rate; (2) it has the ability to mitigate harmonics and DC offset; and (3) it has simplicity in execution. A voltage source converter (VSC), boost converter, 1‐ϕ grid, ripple filter, and nonlinear loads are all part of the system. Feeding 1‐ϕ nonlinear loads and the grid with active power from the solar array is managed by the VSC. Furthermore, grid current quality is enhanced by the use of VSC. Between the solar array and DC‐link capacitor, there is a boost converter that uses the perturb and observe (P&O) technique to track the maximum power from the SPVA. The primary aim of the proposed system is to remove power quality (PQ) issues brought on by nonlinear and imbalanced loads and to supply sinusoidal grid currents during solar irradiance fluctuations. Additionally, a comparison between 1ϕ‐CBF‐FLL control and other control algorithms is presented. The effectiveness of this 1ϕ‐CBF‐FLL control is examined under varying nonlinear loads and in various environmental settings. Test results are used to confirm the simulated results of the proposed system. According to the IEEE‐519 standard, the recommended control may achieve a source current of total harmonic distortion (THD) of 4.02%, which is lower than 5%, a source voltage of THD of 3.21%, and a load current of THD of 24.54%.
