| Abstract: | To study the small-signal stability of grid-connected microgrid with inverter-interfaced distributed resources,a complete small-signal dynamic model of the grid-connected microgrid is developed.The model consists of two sub-models: a dynamic sub-model of network and loads,and a dynamic sub-model of inverter adopting power(or voltage) and current double-loop control.Firstly,how the equivalent impedance between the penetrated distribution network and the microgrid impacts on the small-signal stability of the ... |
