Abstract
The development of highly efficient long-term electricity storage technology is of great interest to scientists and engineers, particularly due to the inflexibility of renewable energy sources regarding key parameters that need to be maintained in the energy system. One such electricity storage technology is compressed air energy storage (CAES), which enables long-term energy storage with flexible capacity and rated power size. However, one of the main challenges hindering the advancement of this technology is its efficiency and high investment costs, especially for small and micro installations up to 1 MW. Traditional control methods require the use of pressure reducers, resulting in energy losses due to pressure drops in the compressed air tank during the unloading process. Nonetheless, a stable and highly efficient control algorithm for air storage discharge remains elusive. In this study, we investigate a control algorithm that considers the constant air energy provided into the piston chamber. Our proposed algorithm dynamically adjusts the width and pulse of the portion of compressed air based on pressure signals in the compressed storage tank and the position of the piston. We estimate that the efficiency of converting the mechanical energy of compressed air into electrical energy in the piston expander may reach as high as 70-80%.
