Descripción
This paper focuses on complex-variable sliding-mode control (CV-SMC) of grid-following inverters that interface renewable energy sources (RESs) with non-ideal grids subject to imbalances, harmonic distortion, frequency variations and voltage drops. The following three control objectives are set: (1) Substantial DC-link capacitance reduction via high-dynamic-performance control of the DC-link voltage, (2) phase-locked loop (PLL)-less and grid voltage sensorless control, and (3) injected grid current free from imbalances and harmonic distortion. Objectives 1 and 3 are tackled by proposing a CV-SMC scheme based on a non-conventional, energy-based, nonlinear switching function, combined with a method for computing the instantaneous reference values it contains. Such switching function leads to command the DC-link voltage together with the grid current by means of a single high-dynamic-performance control-loop. As for objective 2, a nonlinear observer estimating both the grid voltage and its frequency is proposed to replace the typical “grid voltage sensors + PLL” solution, thus enabling the inverter to self-synchronize with non-ideal grids by measuring only the grid current. The design, tuning, stability analysis and implementation of both the CV-SMC algorithm and the observer are addressed. Simulation and experimental results confirm the proposal’s ability to meet the three control objectives in presence of grid disturbances.
