Inhalt:
This paper applies the differential evolution (DE) metaheuristic for controllers’ tuning in two different structures of parallel-connected three-phase four-wire voltage source inverters (VSI), a four-leg (4L) and a neutral-point clamped (NPC), both composed of P and PI controllers inserted in the power-sharing, voltage, and current loops. The DE algorithm optimizes cost functions related to the tuning problem, being employed at first to adjust voltage and current controllers in each VSI and then to adapt of power-sharing controllers. The search ranges are defined considering the frequency response tuning method and a stability analysis based on a small signal microgrid model.
