Novel battery storage technologies are very qualified for levelizing the output of the renewable energy sources so as to give grids more safe energy.For describing their common characters and comparing their differences，a compatible model for novel battery energy storage system is presented to stabilize the intermittent power of renewable energy sources.The new battery technologies taken for examples are lithium iron phosphate battery（LFP），sodium sulfur battery（NaS）and vanadium redox battery（VRB）.The battery energy storage system（BESS）cost are considered in the model as an important comparison basis.Numerical results show the validity of this model and give the optimal configuration of these on-site BESSs.
