Lyapunov Based-Distributed Fuzzy-Sliding Mode Control for Building Integrated-DC Microgrid With Plug-In Electric Vehicle

Abstract

This paper presents a distributed control strategy based on fuzzy-sliding mode control (FSMC) for power control of an infrastructure integrated with a dc-microgrid, which includes photovoltaic, fuel cell, and energy storage systems with plug-in electric vehicles (PEVs). In order to implement the proposed control strategy, first, a general nonlinear modeling of a dc-microgrid based on related dc-dc converters to each dc power sources is introduced. Second, a power management strategy based on fuzzy control for regulating the power flow between the hybrid dc sources, PEVs is proposed. Third, to retain the balance between the requested power and the output power, adaptive FSMC strategy, for controlling the battery energy storage and fuel cell, is suggested. Finally, experimental results are presented to validate the potential of the proposed power flow control strategy.
