Abstract:The research significance of various scientific aspects of photovoltaic (PV) systems has increased over the past decade. Grid-tied inverters the vital elements for the effective interface of Renewable Energy Resources (RER) and utility in the distributed generation system. Currently, Single-Phase Transformerless Grid-Connected Photovoltaic (SPTG-CPV) inverters (1-10 kW) are undergoing further developments, with new designs, and interest of the solar market. In comparison to the transformer (TR) Galvanic Isolation (GI)-based inverters, its advantageous features are lower cost, lighter weight, smaller volume, higher efficiency, and less complexity. In this paper, a review of SPTG-CPV inverters has been carried out. The basic operational principles of all SPTG-CPV inverters are presented in details for positive, negative, and zero cycles. A comprehensive analysis of each topology has been deliberated. A comparative assessment is also performed based on weaknesses, strengths, component ratings, efficiency, total harmonic distortion (THD), semiconductor device losses, and leakage current of various SPTG-CPV inverters schemes. Typical PV inverter structures and control schemes for grid connected three-phase system and single-phase systems are also discussed, described, and reviewed. Comparison of various industrial grids-connected PV inverters is also performed. Loss analysis is also performed for various topologies at 1 kW. Selection of appropriate topologies for their particular application is thoroughly presented. Then, discussion and forthcoming progress are emphasized. Lastly, the conclusions are presented. More than 100 research publications on the topic of SPTG-CPV inverter topologies, configurations, and control schematics along with the recent developments are thoroughly reviewed and classified for quick reference.

“…In order to verify the desired operation of the proposed controller, a grid-connected single-phase inverter is simulated in Matlab/Simulink under normal and faulty grid conditions, since the implementation of the FRT algorithm in single-phase systems has shown an increasing interest recently [23], [22]. The power system and controller parameters are shown in Table I.…”

“…In [21], the importance of the FRT gain is being stated and different techniques for setting the maximum injected active current during fault are shown, while in [4], different power references are being set according to the desired ridethough strategy. Recently, increasing interest is shown in incorporating the FRT requirements into single-phase systems, such as in [23], [22], where the orthogonal signal generator (OSG)-based PLL principle is used to control a single-phase PV system under grid faults. As a result, there exist different FRT control schemes to support the power grid via reactive power injection; however, to the best of our knowledge, in order for these methods to be implemented in combination with a droop control strategy, a switching action between the two separate control dynamics is required, which can lead to integration windup and instability [17], [2].…”

“…It is important for every voltage-controlled, in particular, droop-controlled, distributed generation unit to possess a current-limiting property in a completely decentralized manner, which should be maintained at all times during both normal and abnormal grid conditions, i.e., during grid faults [27]- [30]. Fault current-limiting controllers can be applied to achieve the desired current limitation by either triggering suitably designed protection circuits [29], [31], [32] or by using several low-voltage ride-through structures [33], [34], which will continue injecting power to the grid with a limited current. Several of these methods are based on algorithmic control schemes and lack from a rigorous stability proof.…”

Abstract-A current-limiting droop controller is proposed for single-phase grid-connected inverters with an LCL filter that can operate under both normal and faulty grid conditions. The controller introduces bounded nonlinear dynamics and, by using nonlinear input-to-state stability theory, the current-limiting property of the inverter is analytically proven. The proposed controller can be operated in the set mode to accurately send the desired power to the grid or in the droop mode to take part in the grid regulation, while maintaining the inverter current below a given value at all times. Opposed to the existing current-limiting approaches, the current limitation is achieved without external limiters, additional switches or monitoring devices and the controller remains a continuous-time system guaranteeing system stability. Furthermore, this is achieved independently from grid voltage and frequency variations, maintaining the desired control performance under grid faults as well. Extensive experimental results are presented to verify the droop function of the proposed controller and its current-limiting capability under normal and faulty grid conditions.
