The power station, with a 300MW system, is claimed to be the largest compressed air energy storage power station in the world, with highest efficiency and lowest unit cost as well.
This study aims at presenting a devised operational control strategy applied to distributed compressed air energy storage systems, as well as assessing the best scenario for optimal utilization of grid-integrated renewable energy sources at small scales in dynamic electricity markets. Profit maximization for the end consumer is the major goal.
Large-scale compressed air energy storage (CAES) systems can be regarded as conventional technology. They have certain environmental advantages if compared to pumped hydro energy storage and allow for a much larger number of potential sites.
CONCLUSIONS Adoption of energy storage at the customer side integrated in local utility electrical grids is feasible and would provide operational and economy benefits. Distributed small-scale compressed air energy storage systems are possible to build and apply in ways similar to electrical batteries.
4.1. Standalone liquid air energy storage In the standalone LAES system, the input is only the excess electricity, whereas the output can be the supplied electricity along with the heating or cooling output.
Economic operation of the energy storage unit is a complex problem because of the time dependency of the storage capacity where sufficient energy reserves must be maintained in case of grid loss, the solar irradiation or wind speed uncertainty at the location, and the real-time LMP variability throughout the day.
