| Abstract: |
| The components of DG and microgrid are analyzed in detail and the requirements of modeling for transient simulation in general applications are introduced. The modeling method for various DG units is emphasized，based on which，the object-oriented concept is adopted in the design and implementation of the transient simulation program for DG and microgrid. The hierarchical design is applied to clarify the relationship among computation resource，simulation calculation and advanced application. The detailed design of objects and interfaces reduces the program coupling and enhances as well the cohesiveness of objects and the reusability of algorithms. The program supports the capabilities of modeling and computation at the circuit and element level，which can be easily extended to different simulation scenarios. |
