The stochasticity and volatility of renewable energy power generation have become the main factors affecting its large-scale application. Large-scale, low-carbon thermal energy storage system can provide stable, reliable, and economical power regulation for renewable energy power generation system. The thermal energy storage capacity in the renewable energy system needs to be optimized to take account of reliability, low carbon and economy. In this paper, the carbon emission allowances is considered, the thermal energystorage capacity optimization model of the wind is established, concentrating solar power(CSP) and gas energy system. The importance of the thermal energy storage system in the wind-CSP-gas energy system is verified. The impact of the carbon emission allowances on the thermal energy storage capacity planning and system operation is analyzed.The thermal energy storage capacity planning for the wind-CSP-gas energy system to reduce carbon emissions are proposed.
