“…In case of half-bridge (HB) capacitive divider central point is grounded to limit the leakage current to guarantee the regulation of CMV. This leakage current flows though the parasitic capacitance of solar PV modules [42]. Low cost is the distinguishing feature, but the output voltage waveforms with two levels, switches must withstand high potential and highly distorted output current results in high electromagnetic inference (EMI) emissions and is considered a drawback of this topology [43].…”

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.

“…When a master DG receives a grid-connect signal, because the frequency, voltage, and phase of the microgrid in the PCC are inconsistent with the main grid, the microgrid system should first enter the synchronizing mode. During the process of synchronization for DGs, the microgrid must meet the following synchronization criterion in the IEEE Standard 1547-2003 for the 0-500 kVA rated capacity [32,34,35].…”

This paper introduces a distributed secondary control algorithm for automatic generation control (AGC) and automatic voltage control (AVC), which aims at matching area generation to area load and minimizing the total generation cost in an alternating current (AC) microgrids. Firstly, the control algorithm utilizes a continuous-time distributed algorithm to generate additional control variables to achieve frequency-voltage recovery for all distributed generators (DGs). Secondary, it solves the economic dispatch problem (EDP) by a distributed economic incremental algorithm in the secondary control level, which avoids the problem caused by communication speed inconsistency between secondary and tertiary control levels. This study also utilizes a fully distributed strategy based on secondary communication network to estimate the total load demand. In addition, the proposed algorithm can be used to realize a seamless handover from the islanded mode to the grid-connected mode, run under the condition of short time communication system out of action, and help to realize the plug and play function. Lastly, the stability of the proposed control algorithm is analyzed and proved, and the effectiveness of the method is verified in some case studies.

Objective A conservative power theory (CPT) based two‐stage three‐phase multi‐functional grid‐connected photovoltaic (PV) inverter (MGCPI) with auxiliary battery storage system (BSS) is proposed in this article. This proposed configuration offers selective power injection and power conditioning to the consumers. A power management (PM) algorithm is developed to decide the best mode of operation of the MGCPI, taking into account the state‐of‐charge (SOC) of the BSS and the available power at the solar‐PV source for effective coordination between BSS and PV source. Methods CPT is used for computing the MGCPI current reference signals for multi‐functional operations. The feed‐forward linear control systems are designed using classical frequency response analysis for a synergetic operation of BSS and MGCPI. The whole system configuration is modeled using MATLAB/Simulink and validated in real‐time with PM algorithm for unbalanced linear and nonlinear loads using OPAL‐RT based OP4500 grid emulator. Result The injected power, percentage THD of individual phase currents, true power factor, and unbalanced current are measured for various modes of operation. The proposed MGCPI with BSS improves the power quality (PQ) and also injects seamless power at the point of common coupling (PCC) to reduce the grid consumption. Conclusion The real‐time results demonstrate the effectiveness of the proposed approach for unbalanced nonlinear loads in smart electric grid, provisioning harmonic‐free electrical power as per the requirements of IEEE 519‐2014, IEEE 1547a‐2018 standards.
