能源互联网中自能源的孤岛控制研究
An Islanding Control Strategy Research of We-Energy in Energy Internet
摘要
Abstract
In energy internet combined with more we-energies (WE),the reactive power of the traditional droop control often deteriorates due to its dependence on the line impedances.What's more,the output amplitude and frequency of the voltage are difficult to be limited in a reasonable range.Thus,this paper proposed an improved droop control strategy based on exponential function.According to the relationship between power and voltage,frequency,the premise condition that the reactive power of WE can achieve proportional distribution had been analyzed and an exponential droop control was proposed to improve reactive power sharing.Using small signal modeling analysis shows that the stability of the proposed control method.In the end,the simulations including line impedance imbalance,the different capacity of We-Energies and the hybrid control combined with traditional droop control and exponential droop control were studied,and simulation and experimental results were presented to validate the effectiveness of the proposed method.关键词
