Modeling and performance assessment of an isolated wind-diesel system with flywheel energy storage system

Abstract

This paper proposes incorporation of a flywheel energy storage system (FESS) into hybrid wind-diesel power plant for system frequency and voltage response improvement. The impact of hybrid wind-diesel energy storage systems under various forms of disturbances, such as load disturbance, wind disturbance, wind park disconnection, and step variations in wind is presented and analyzed. The standard IEEE models for different components of hybrid wind diesel power system are considered. Simulations in the time domain are carried out in order to test the performance of proposed system. The positive impact of FESS used in wind-diesel hybrid power system is demonstrated through a series of simulation cases carried for various types of disturbances.
