阶梯式碳交易机制下的园区综合能源系统低碳鲁棒经济调度研究OA

For the purpose of carbon emission reduction as well as efficient and economic operation of park integrated energy systems(PIES),this paper proposes a low-carbon,robust,and economic dispatch strategy that accounts for flexible equipment operation characteristics and is based on a stepped carbon trading mechanism.First,a flexible equipment operation model that incorporates start and stop conditions was established within the PIES energy flow framework.Then,a scenario analysis approach was used to deal with uncertainty in source-side renewable energy output,and a multi-type electric-thermal flexible load model was established that reflects the characteristics of dispatchable resources on the load side,to improve operational robustness.Finally,based on the stepped carbon trading mechanism,an optimal economic dispatch model was constructed,which incorporates multiple and complex operational constraints across the source,load,and energy conversion/storage sides.Experimental results show that,when accounting for costs including energy purchase,equipment operation and maintenance,and carbon trading,the proposed strategy enables simultaneous optimizations of carbon emission reduction and economic performance improvement for PIESs.
