考虑碳流约束的电力系统能碳安全域模型与计算方法OA北大核心CSTPCD

Aiming at the current carbon emission reduction tasks and the safe and stable operation requirements of the power system,the low-carbon safe operation technology of the power system is studied.The existing energy flow security region model makes security monitoring and control more scientific and effective,but it ignores the potential"high carbon"risk during system operation.Based on this,a model and calculation method for the energy and carbon coupled security region(referred to as the energy-carbon security region)considering carbon flow constraints are proposed,aiming to ensure system security while reducing emissions and improving efficiency.To fully characterize the low-carbon operation capability limit of the power system,the total supply capability curve and total accommodation capability curve models of the power system considering carbon flow constraints are proposed from the perspectives of load and source ends,respectively.Based on the working point of the total supply capability,the simulation fitting calculation method of the energy-carbon safety boundary is proposed,and the dimension reduction observation of the energy-carbon security region is realized.Finally,the validity of the proposed model is verified by combining the cases.
