Modeling and Simulation of Compressed Air Energy Storage (CAES) System for Electromechanical Transient Analysis of Power System

CABS system electromotor transient model was established from the view of equipment and the grid interface, based on Power System Analysis Software Package (PSASP). The model was divided into energy storing sub-system model part and generating sub-system model part, and the normal and abnormal dynamic characteristics after CABS connected to the grid were simulated by this model. The validity of this model was theoretically verified by applying it into example systems and testing.,according to detecting the system responses caused by power system contingency and the sudden change of CABS characteristics. This model provides a basic platform for studying CABS system characteristics, and also provides necessary technical support to the security and stability of power system operation when integrating renewable energy into the grid.
