This paper aims to design an adaptive fuzzy logic voltage controller for a residential MG including PV-array and flywheel/battery hybrid energy storage implemented in a DC bus configuration. Specifically, the controller is developed for the MG islanded operation. The most relevant simulation scenario is considered the maximum load, defined based on load power profiles and correlated PV generation profiles. Considering the DC bus voltage error and the battery state of charge as inputs, the fuzzy controller elaborates a power correction to be applied to the regular power assignments determined by the normal operation power management. Simulation results prove that the controller achieves very good performances in supplying the critical load during islanding, while maintaining adequate levels of voltage and frequency towards the critical load.

Abstract

This paper aims to design an adaptive fuzzy logic voltage controller for a residential MG including PV-array and flywheel/battery hybrid energy storage implemented in a DC bus configuration. Specifically, the controller is developed for the MG islanded operation. The most relevant simulation scenario is considered the maximum load, defined based on load power profiles and correlated PV generation profiles. Considering the DC bus voltage error and the battery state of charge as inputs, the fuzzy controller elaborates a power correction to be applied to the regular power assignments determined by the normal operation power management. Simulation results prove that the controller achieves very good performances in supplying the critical load during islanding, while maintaining adequate levels of voltage and frequency towards the critical load.
