Power Dispatch Fuzzy Control-Based Strategy for Improved Performance in Single-Phase Microgrids

Abstract

In this work, an isolated single-phase microgrid based on parallel-connected inverters is analyzed to supply the power demanded by the load. A controller based on the interconnection of Hamiltonian systems with fuzzy components is proposed to attack the problem of current tracking and voltage regulation, as well as a droop controller for power dispatch. It is determined that the incorporation of a structure based on fuzzy logic improves the transient response of the closed-loop system in current and voltage monitoring. Comparative numerical results are shown to demonstrate the effectiveness of the proposed scheme.
