英文摘要 |
Power-electronic-converter (PEC) based distributed generations (DGs) are widespread in microgrids, and
they differs significantly from the conventional synchronous generators in control schemes and dynamic characteristics.
The diversity of DG control methods and the increasing penetration of PEC DGs are leading to various challenges in
coordinated control and stable operation of low-inertia microgrids. The coexistence of heterogeneous microsources and
loads within the microgrid may result in interactions among the DGs and loads. The coupling among the devices with
different characteristics reshape the dynamic responses of the microgrids and induce stability issues. In this paper, firstly,
typical operating characteristics and stability issues of the microgrids with increasing penetrations of renewable energy
resources are summarized. The modularized dynamic modeling method of microgrid with multiple energy resources and
multiple conversions interface is described in detail. On this basis, the eigenvalue analysis method and basic steps for
dynamic stability analysis of microgrid are given. Furthermore, the proposed dynamic modeling and dynamic stability
analysis method are adopted to model and analyze the Dongao Island smart microgrid. The discussion of the dynamic
stability analysis method of the multiple energy resources and multiple conversions microgrid system can provide the
theoretical foundation for the modeling and analysis of the microgrid extension and application. |
