摘要:

针对当前电力系统碳减排任务与安全稳定运行需求,研究电力系统低碳安全运行技术。现有的能量流安全域模型使电力系统安全监视与控制更加科学有效,但忽略了系统运行过程中可能存在的“高碳”风险。文中提出了一种考虑碳流约束的电力系统能碳耦合安全域(简称能碳安全域)模型与计算方法,旨在保证系统安全性的同时减排提效。为完整刻画电力系统的低碳运行能力极限,分别从负荷端和源端角度提出了考虑碳流约束的系统最大供电能力曲线及最大消纳能力曲线模型。基于系统最大供电能力工作点,提出了能碳安全边界仿真拟合计算方法,实现了能碳安全域的降维观测。最后,结合算例验证了所提模型的有效性。

Abstract:

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.
