“…The difference lies in that the MPPT control is implemented on the DC-DC converter, while the other functionalities are performed on the control of the PV inverter. There are other control solutions available for single-phase grid-connected PV systems [76]- [78]. For example, the instantaneous power is controlled in [77], where the synthesis of the power reference is a challenge; in [78], a onecycle control method has been applied to single-stage single-phase grid-connected PV inverters for low power applications.…”

A still booming installation of solar photovoltaic (PV) systems has been witnessed worldwide. It is mainly driven by the demand of "clean" power generation. Grid-connected PV systems will become an even active player in the future mixed power systems, which are linked by a vast of power electronics converters. In order to achieve a reliable and efficient power generation from PV systems, stringent demands have been imposed on the entire PV system. It in return advances the development of power converter technology in PV systems. This paper thus takes an overview of the advancement of power electronics converters in single-phase PV systems, being commonly used in residential applications. Demands to single-phase grid-connected PV systems as well as the general system control strategies are also addressed in this paper.

“…A synchronization technique is used in grid-connected converter control systems to compensate non-ideal supply voltages and to achieve a higher frequency variability [7]. In [8], a simplified reactive power control (SRPC) strategy is proposed for the inverters in single-phase grid-connected PV systems. With this strategy, the current-mode asynchronous sigma-delta modulation (CASDM) is adopted to improve the current control's dynamic response and to reduce both current harmonic distortion and electromagnetic interference.…”

Design and implementation of a low cost grid-connected 5kVA solar photovoltaic (PV) system is proposed in this paper. Since the inverter is a major component of the PV system, the B4 inverter used in this paper reduces the total cost of the PV system. In order to eliminate the massive transformer, the PV system is connected to the grid through IGBT switches. In addition to injection of active power into the grid, the B4 inverter can compensate reactive power and reduce harmonics of the nonlinear loads. A TMS320F28335 DSP processor is used for effective control of the B4 inverter. Various features of this processor enable the implementation of the necessary control algorithms. As a first step, the PV system is simulated and evaluated in Matlab/Simulink. In the second step, hardware circuits are designed and implemented based on the simulation results. The operation of the PV system has been evaluated under balanced, unbalanced, linear and nonlinear loads which proves its accuracy and efficiency.

Abstract-Repetitive control (RC) with linear phase lead compensation provides a simple but very effective control solution for any periodic signal with a known period. Multirate repetitive control (MRC) with a downsampling rate can reduce the need of memory size and computational cost, and then leads to a more feasible design of the plug-in repetitive control systems in practical applications. However, with fixed sampling rate, both MRC and its linear phase lead compensator are sensitive to the ratio of the sampling frequency to the frequency of interested periodic signals: (1) MRC might fails to exactly compensate the periodic signal in the case of a fractional ratio; (2) linear phase lead compensation might fail to enable MRC to achieve satisfactory performance in the case of a low ratio. In this paper, a universal fractional-order design of linear phase lead compensation MRC is proposed to tackle periodic signals with high accuracy, fast dynamic response, good robustness, and cost-effective implementation regardless of the frequency ratio, which offers a unified framework for housing various RC schemes in extensive engineering application. An application example of programmable AC power supply is explored to comprehensively testify the effectiveness of the proposed control scheme.Index Terms-repetitive control, DC/AC inverter, multirate repetitive control, phase lead compensation, Lagrange interpolation polynomial, programmable AC power supply
