Simulation of Battery/Supercapacitor Hybrid Energy Storage System for More Electric Aircraft

The electrical power systems of next-generation commercial airline aircraft are undergoing significant development. Their main characteristic consists in the replacement of hydraulic, pneumatic and mechanical energy with electrical energy. The aircraft power system includes the power generation system, the distribution system and the loads. The More Electric Aircraft concept is a fast-developing tendency in the modern aircraft industry. This paper presents Battery/Supercapacitor Hybrid Energy Storage System for the More Electric Aircraft. This system is modeled and, on one hand, there is proposed a reasonable control strategy and on the other hand, the steady and transitory characteristics are analyzed being obtained a good accuracy. The achievements of the energy storage device are examined by simulation.
