考虑到传统模型无法保证电网安控系统的稳定性,提出数字孪生驱动下的电网安控系统虚拟模型构建研究。计算送电系统的等值电势阻抗,得到电网安控系统的电磁功率。建立系统线路的运动方程,完成系统暂态稳定性分析。在数字孪生驱动下,分析电网随机潮流的期望值,得到电网随机潮流的线性化方程,结合电网随机潮流的差分化和初始化处理,计算系统随机潮流,通过构建电网安控系统虚拟模型,实现系统稳定控制。仿真结果表明,数字孪生驱动下的电网安控系统虚拟模型可以保证电网安控系统稳定运行。
Considering that the traditional model can not guarantee the stability of power grid security control system,a research on virtual model construction of power grid security control system driven by digital twin is proposed.The equivalent potential impedance of the power transmission system is calculated and the electromagnetic power of the power network security control system is obtained.The equation of motion of the system circuit is established and the transient stability of the system is analyzed.Under the digital twin drive,the expected value of power grid random power flow is analyzed,the linearization equation of power grid random power flow is obtained,and combined with the differential differentiation and initialization processing of power grid random power flow,the system random power flow is calculated,and the system stability control is realized by constructing the virtual model of power grid security control system.The simulation results show that the virtual model of power grid security control system driven by digital twin can guarantee the stable operation of power grid security control system.
