摘要
在当今时代,电力系统是日常生活中的关键部分。为保证电力系统运行稳定,该文首先利用虚拟惯性注入方法,模拟出电力系统的惯性特征。其次,建立约束条件,以此保证电力系统的稳定性,为后续负荷减流提供基础。最后,构建负荷减流优化模型,实现发电厂的负荷减流优化。从优化结果和负荷分配响应速度2方面分析电厂的负荷减流优化。结果表明,所提方法的耗煤量和偏差较低,分别是318.59 t和0,负荷分配速度较快,一般在4.9 s左右,证明所提方法的能源消耗较少,准确率较高,机组的反应力较快,能够完成发电厂的负荷减流优化,维持电力系统的稳定和平衡,推动电力系统的发展。
Nowadays,power systems are a critical part of daily life.In order to ensure the stability of the power system,this paper first uses virtual inertia injection method to simulate the inertia characteristics of the power system.Secondly,constraints are established to ensure the stability of the power system and provide a basis for subsequent load current curtailment.Finally,a load curtailment optimization model is constructed to realize the load curtailment optimization of the power plant.The load curtailment optimization of the power plant is analyzed from two aspects:optimization results and load distribution response speed.The results show that the coal consumption and deviation of the proposed method are low,which are 318.59 t and 0 respectively,and the load distribution speed is fast,generally about 4.9 s.It proves that the proposed method consumes less energy,has high accuracy,and has fast unit response,thereby can complete the load curtailment optimization of the power plant,maintain the stability and balance of the power system,and promote the development of the power system.
