Abstract：

In　this　current　paper,　the　influence　of　system　efficiency　and　system　parameters　for　simple　compressed　energy　storage　system　were　studied.　EES　software　is　used　to　simulate　the　pressure　of　system　and　efficiency　of　compressors,　expanders,　and　pump　for　getting　the　optimal　parameters　of　system.　The　results　show　that:　for　the　simple　system,　when　the　expander　inlet　pressure　is　6000kPa　and　compressor　outlet　pressure　is　4000kPa,　the　system　efficiency　could　get　the　maximum,　and　it　is　76.2%.　It　is　a　better　way　for　improving　the　efficiency　of　compressor　and　expander　than　the　pump　for　system　performance.　©　(2013)　Trans　Tech　Publications,　Switzerland.
