Abstract:

In this paper a new format of hybrid Pulse Width Modulation (PWM) interface between solar photovoltaic (PV) arrays and superconducting magnetic energy storage (SMES) devices in transformer-less inverters is suggested to be attached to the grid. The proposed PWM technique also improves the performance of the inverter by decreasing leakage currents and integrating harmonic distortion (THD), which are two significant disadvantages of transformer less inverter topologies, and increases power conversion efficiency. To make use of the diversified production of solar PV systems and the quick responsiveness capacity of SMES, Hybrid PWM strategy dynamically modifies the switching patterns to enable stable grid interaction and the stability of energy provision. The modelling and experimental results provide the effectiveness of the suggested methodology because they indicate that the quality of power, power efficiency, and system stability are largely enhanced in contrast to traditional PWM approaches. This convergence makes it easier to have an increasing integration of renewable energy sources in the modern power grids by providing a sustainable solution to enhanced grid-tied inverter systems.
