摘要

近年来,可再生能源并网普及率不断提高。这些并网行为,既影响着电网的稳态行为,也影响着电网的动态行为。本文对传统的负荷潮流规划进行了改进,以适应并网太阳能光伏发电系统。建立了spv集成电力系统的大信号分析模型。举例说明了不同的测试用例,以了解SPV电力系统在不同气象变量和不同电网规格下的网络行为。估计了spv集成电力系统的临界清净时间。

Current injection modelling based large-signal analysis of a grid-connected solar photovoltaic power system
In recent years, penetration level of the grid-connected renewables has been increasing. These grid integration, affects the steady state as well as dynamic behavior of the power system network. In this paper, the conventional loadflow programme is modified to accommodate grid-connected solar photovoltaic (SPV) power system. A model of SPV-integrated power system is developed to carry out large-signal analysis. Various test cases are illustrated to appreciate the network behavior for varying meteorological variable and different grid-specifications pertaining to SPV power system. Critical clearing time of SPV-integrated power system is estimated.
