This study presents the development, design and performance analysis of a multistring bidirectional solar inverter connected to the grid (BSICG). An algorithm for the independent global maximum power tracking was both developed and implemented, which produced a system immune to non-uniform irradiation conditions with the aim of applying such on DC (direct current) microgrids connected to a conventional AC (alternating current) grid on the BSICG, which is characterised by bidirectional power flow management. The main advantage of this proposal is thus highlighted as the stabilisation of the voltage on the DC bus even when confronted with irradiance intermittencies from photovoltaic solar energy. All theories are presented and corroborated through experimental results obtained from a 2.0 kW prototype.

“…These controllers are widely used for their simple structure, low cost and ease of implementation, however, they cannot compensate the steady‐state error in the term of sinusoidal input [10]. Recently, discrete control strategies like repetitive control [11–14], internal model control [15], sliding‐mode control [16–18] and dead beat control [19–21] has been proposed for inverters. One of the advantages of repetitive control is the minimum output harmonic distortion of the load but it consists of some limitations including: slow dynamics, large memory capacity, poor tracking and poor performance to different disturbances.…”

“…When the mathematical model is different from the actual object, it not only fails to achieve good control effect, but also reduces the output performance and endangers the safe operation of the converter [13]. Compared with other controllers, repetitive control has the following advantages: its repeatability can be used to achieve harmonic suppression of periodic interference signals [14], [15]; it has good steady-state performance, and can theoretically realize no static error tracking [16]. However, its dynamic performance and performance in suppressing non-periodic interference are not good.…”

With the increasing of the grid-connected capacity of renewable energy such as wind energy and solar energy, its instability, intermittence and uncontrollability have a serious impact on the stable operation of power system, such as voltage fluctuation, frequency flicker, etc. Therefore, Electric Spring (ES) system has become a current research hotspot. Aiming at the deficiencies of the resonance control strategy, a control method that combines quasi-proportional resonance (QPR) control and repetitive control is proposed. The quasi proportional resonance control is used to realize the tracking without static error, and the internal model principle of repetitive control is used to suppress the periodic disturbance of the grid voltage, so as to improve the power quality of the grid. Compared with the traditional quasi proportional resonant control, the introduction of repetitive control can effectively improve the steady-state accuracy, reduce the system harmonic and enhance the ability of anti-harmonic interference. The modeling of ES and the design method of repetitive controller parameters are discussed in detail. The simulation model is built using MATLAB / Simulink, and the ES experimental platform is built with dSPACE as the control core, the results verify the feasibility and effectiveness of the proposed control strategy.
