The reverse peak load characteristics of wind energy result in a large portion of the wind power wasted. In order to solve this problem

a novel biomass-fired power plant integrated by CaO energy storage under high temperature for wind power accommodation with CO2 negative emissions is proposed. A model based on CaO energy storage integrated biomass-fired power plants is built to simulate wind power accommodation and CO2 capture. The thermodynamic performances of the system are analyzed using Aspen Plus software and the influences of the carbonation reactor positions on the energy storage efficiency and the CO2 capture are also discussed. Meanwhile

combined with the sensitive analysis on carbonation reactor and calcinations reactor

the energy storage efficiency of the system is calculated to be 39. 4% while the CO2 capture for wind power reaches 0. 792 kg/(kW·h)under the optimal operation condition.
