Stochastic Operation Planning of Wind-Thermal Generating Systems Considering Compressed Air Energy Storage

With the massive deployment of renewable generation resources especially wind power generation in many electricity markets, the intermittency issues related to these resources must be addressed. As a possible solution, energy storage systems (ESS) can be considered to cope with wind power variability and support its integration. In this paper, compressed air energy storage (CAES) is employed to help integrate a high penetration of wind generation into the electricity market. To this end, a stochastic market-clearing model considering wind generation uncertainty is presented. Case studies in a three-bus test system are conducted to demonstrate the CAES effectiveness for the wind power integration. The results indicate that the operation of CAES in wind-thermal generating systems can be very beneficial for the electricity market performance from the economical and operational viewpoints
