“…Fig.2 (Silva et al, 2004;Velasco et al, 2011) or substituted by the estimated -axis component, (Filho et al, 2008;Rodr'iguez et al, 2011;Karimi-Ghartemani, 2013). The main problem affecting the performance of a single phase PLL is that any mismatch/error in the virtual -axis component (during transient or steady state) will produce double-frequency ripple component that adversely affects the dynamic performance and the stability of the PLL.…”

“…Phase-locked loops (PLLs) are widely used for interfacing power electronic converters to single and three-phase grids, (Chung, 2000;Golestan et al, 2013;Silva et al, 2004;Velasco et al, 2011) There are a few single-phase PLL schemes widely discussed in the literature that differ in their structure and estimation laws: the Inverse Park-PLL (IP-PLL) (Filho et al, 2008;Rashed et al, 2013), the Synchronous Reference Frame PLL (SRF-PLL) (Nicastri et al, 2010), the Second-Order Generalized Integrators (SOGI)-based Frequency-Locked Loop (FLL) (SOGI-FLL) (Rodr'iguez et al, 2011), the D-filter-based estimation PLL (Shinnaka, 2011), the Enhanced PLL (EPLL) (KarimiGhartemani, 2013;Karimi-Ghartemani et al, 2012) and the Modified Mixer Phase-Detector based PLL (MMPD-PLL), (Thacker et al, 2011). Some of this research work has been aimed at studying the design and performance analysis of single-phase PLLs.…”

Purpose -The purpose of the paper is to introduce the Dynamic Phasor Modelling (DPM) approach for stability investigation and control design of single-phase Phase Locked Loops PLLs. The aim is to identify the system instabilities not predicted using the existent analysis and design methods based on the simplified average model approach.Design/methodology/approach -This paper starts by investigating the performance of three commonly used PLL schemes: the Inverse Park-PLL, the SOGI-Frequency-Locked-Loop and the Enhanced-PLL, designed using the simplified average model and will show that following this approach, there is a mismatch between their actual and desired transient performance. A new PLL design method is then proposed based on the DPM approach that allows the development of fourthorder DPM models. The small-signal eigenvalues analysis of the 4 th order DPM models is used to determine the control gains and the stability limits.Findings -The DPM approach is proven to be useful for single-phase PLLs stability analysis and control parameters design. It has been successfully used to design the control parameters and to predict the PLL stability limits, which have been validated via simulation and experimental tests consisting of grid voltage sag, phase jump and frequency step change.Originality/value -this paper has introduced the use of DPM approach for the purpose of singlephase PLL stability analysis and control design. The approach has enabled accurate control gains design and stability limits identification of single-phase PLLs.

“…The methods are active and passive methods. The active methods [4] inject small signals in the distribution system or force the DG to an abnormal situation, while the connection to the system keeps it under normal conditions. The disturbances inserted in the distribution system may cause power quality deterioration.…”

This study presents a strategy using the synchronized output regulation method (SOR) for controlling inverters operating in stand-alone and grid-connected modes. From the view point of networked dynamic systems, SOR involves nodes with outputs that are synchronized but also display a desirable wave shape. Under the SOR strategy, the inverter and grid are treated as two nodes that comprise a simple network. These two nodes work independently under the stand-alone mode. An intermediate mode, here is named the synchronization mode, is emphasized because the transition from the stand-alone mode to the grid-connected mode can be dealt as a standard SOR problem. In the grid-connected mode, the inverter operates in an independent way, in which the voltage reference changes for generalized synchronization where its output current satisfies the required power injection. Such a relatively independent design leads to a seamless transfer between operation modes. The closed-loop system is analyzed in the state space on the basis of the output regulation theory, which improves the robustness of the design. Simulations and experiments are performed to verify the proposed control strategy.
