Adaptive Nonlinear Sliding Mode Control for DC Power Distribution in Commercial Buildings

Abstract

The developing populace and industrialization power demand prompted the requirement for power generation from elective sources. The desire for this pursuit is solid due to the ever-present common assets of petroleum derivatives and their predominant ecological issues. It is generally acknowledged that sustainable power sources are one of the best answers for the energy emergency. Among these, Photovoltaic (PV) sources have many benefits to bestow a very promising future. If integrated into the existing power distribution infrastructure, the solar source will be more successful, requiring efficient Direct Current (DC)-Alternating Current (AC) conversion. This paper mainly aims to improve controllers’ performance between AC/DC Energy sources and the DC loads using the Adaptive Nonlinear Sliding Mode (ANSM) control method. The proposed ANSM method efficiently controls power quality issues, such as transient response, power flow reliability and Total Harmonics Distortion (THD). The proposed controller is applied for both AC/DC and DC/DC converters and the performance of the proposed controller is validated through simulation checking the above parameters. The simulation results confirm ANSM configuration is more reliable and efficient than the existing fuzzy and sliding mode control methods.
