采用光伏逆变器的全开关模型或详细平均模型对具有高光伏渗透率的大型配电系统进行暂态分析，计算量很大。通过传统的状态空间公式进行暂态分析不适合研究大型配电系统的长期暂态，如与其他控制装置的相互作用、云瞬态和电压闪变等。本文建立了单相逆变器的动态相量模型，有助于对具有高光伏渗透率的大型配电系统进行快速仿真。本文从准平稳范围扩展了暂态分析相量的适用范围。
Transient analysis of large distribution systems with high PV penetration using either the full switching model or even the detailed average model of the PV inverters is computationally intensive. Transient analysis through conventional state-space formulations is not suitable for the study of long-term transients of large distribution systems such as, interaction with other control devices, cloud transients, and voltage flicker. In this work, dynamic phasor model for single-phase inverters are developed, aiding the fast simulation of large distribution systems with high PV penetration. This paper extends the applicable range of phasors for transient analysis from the quasi-stationary range.
