Abstract. - With an increasing capacity of wind energy globally, wind-driven Compressed Air Energy Storage (CAES) technology has gained significant momentum in recent years. However, unlike traditional CAES systems, a wind-driven CAES system operates with more frequent fluctuations due to the intermittent nature of wind power.
