Grid-connected control strategy for solar inverters

Regarding grid-connected solar inverters, the basic control strategies include a maximum power point tracking (MPPT) algorithm (i., increasing effi- ciency and maximizing the energy harvesting), a DC-link voltage control, and a grid-connected current control (i. Their control performance directly influences system stability and grid connection quality. However, as PV penetration increases, conventional controllers encounter. . In this context, I explore a coordinated control method that combines transformer on-load tap changers (OLTC) with solar inverter phase modulation to achieve precise voltage regulation. By leveraging sensitivity-based voltage control domain partitioning, this approach minimizes interdependencies. . This paper proposes a novel sorted level-shifted U-shaped carrier-based pulse width modulation (SLSUC PWM) strategy combined with an input power control approach for a 13-level cascaded H-bridge multi-level inverter designed for grid connection, specifically tailored for photovoltaic (PV) systems. . As an essential interface between the photovoltaic (PV) panels and the utility grid, solar PV inverters are responsible for converting intermittent solar energy to meet the utility grid requirement, where the inverter output should be synchronized with the grid voltage in terms of phase frequency. .
