- Abstract
Aiming at the faults of some weak nodes in the concentrated solar power-photovoltaic (CSP-PV) hybrid power generation system, it is impossible to restore the transient voltage only relying on the reactive power regulation capability of the system itself. We propose a dynamic reactive power planning method suitable for CSP-PV hybrid power generation system The method determines the installation node of the dynamic reactive power compensation device and its compensation capacity based on the reactive power adjustment capability of the system itself The critical fault node is determined by the transient voltage stability recovery index, and the weak node of the system is initially determined. Based on this,the sensitivity index is used to determine the installation node of the dynamic reactive power compensation device. Dynamic reactive power planning optimization model is established with the lowest investment cost of dynamic reactive power compensation device and the improvement of system transient voltage stability. Furthermore, the component of the reactive power compensation node is optimized by particle swarm optimization based on differential evolution (DE-PSO), The simulation results of the example system show that compared with the dynamic position compensation device installation location optimization method,the proposed method can improve the transient voltage stability of the system under the same reactive power compensation cost.
