Abstract

The paper presents the analysis of the dynamic response of a microgrid, obtained by means of two different simulation environments, i.e. EMTP-RV and Simulink. The aim of the study is to investigate on some differences that could arise between the two environments and to explore when such differences could become meaningful, in particular for the analysis of microgrids. The system under study is a medium voltage microgrid coupled to an external network and containing stationary and rotating loads and a battery energy storage system. The considered case studies are: i) a step load change in order to compare the responses in both grid-following and grid-forming control modes for the battery energy storage system; ii) voltage and frequency step changes to compare two types of loads, namely exponential load and induction motor and iii) the islanding transition of the microgrid.

微电网动态响应的计算方面:比较分析

本文通过EMTP-RV和Simulink两种不同的仿真环境，对微电网的动态响应进行了分析。这项研究的目的是调查两种环境之间可能出现的一些差异，并探讨这些差异何时可能变得有意义，特别是对微电网的分析。所研究的系统是一个与外部网络耦合的中压微电网，包含固定和旋转负载以及电池储能系统。考虑的案例研究是:i)为了比较电池储能系统在电网跟随和电网形成控制模式下的响应，采用阶跃负载变化;Ii)电压和频率阶跃变化来比较两种类型的负载，即指数负载和感应电机;iii)微电网的孤岛过渡。
