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.%通过对分布式发电微网系统各组成部分的详细分析,介绍了基于一般应用场景下的暂态仿真建模需求,特别强调了各种分布式电源的建模方式,在此基础上采用面向对象思想设计并实现了分布式发电微网系统暂态仿真程序,应用分层设计明确了计算资源、仿真计算与高级应用间的相互关系,通过对对象和接口的详细设计降低了程序的耦合,提高了对象的内聚性和算法的复用性.分布式发电微网系统暂态仿真程序提供了系统底层的建模与计算能力,同时具有良好的可扩展性,可以满足各种应用场景下的仿真计算需求.
