基于拓扑重构与分网解耦的新能源场站多尺度仿真建模
Multiscale modelling and simulation of renewable energy stations based on topology reconstruction and sub-network decoupling
摘要
Abstract
The establishment of the dual-carbon goal has promoted the rapid development of new energy sources,which has led to a large number of power electronic devices being connected to the new power system,thus changing the operation characteristics of the traditional power system,which is dominated by synchronous generators.The simulation process of the new power system has a large time scale,and the requirements for numerical stability and accuracy are higher than those of the traditional power system simulation.In order to meet the simulation requirements of new energy field stations with high proportion of power electronic converters,this paper proposes a multi-scale simulation modeling method for new energy field stations based on topology reconfiguration,which can realize the efficient simulation of different power electronic topologies with small step lengths.At the same time,for the characteristics of new energy stations with mixed fast and slow dynamic characteristics,this paper proposes a network decoupling method without insertion delay between the power electronic converter branch and the main system,which realizes high-precision parallel simulation with multiple steps.关键词
