传统电网虽然能够实现发电与用电的瞬时平衡，但仍面临着能源危机、环境污染等诸多问题。考虑到这些问题，微电网的开发投入了大量的精力。微电网由负荷和分布式发电机组组成，它们作为一个单一的可控系统运行。本文包括电压型变流器和DSTATCOM的分步控制和建模，以及恒阻抗和恒功率负载的建模。利用模态分析对本文的分析结果进行了仿真分析。通过仿真验证了该数学模型的正确性，然后利用所建立的模型，利用特征值分析方法研究了微电网在(A)有无DSTATCOM存在时的小干扰稳定性。
Although the traditional power network is capable of making the instantaneous balance between power generation and consumption, it still faces many problems such as energy crisis, and environmental pollution. Considering these problems, much effort went into developing Microgrids. Microgrids consist of loads and distributed generation units which operate as a single controllable system. This paper includes the step by step controlling and modeling of voltage-source converters and DSTATCOM and modeling of constant impedance and constant power loads. The results of this paper are simulated and analyzed using modal analysis. This mathematical model is verified by the simulation, Then, by using the introduced models, the small-signal stability of microgrid is studied (a) with and (b) without the existence of DSTATCOM by the eigenvalues analysis method.
