Abstract

Reliability and sustainability of power supply between already existing power network and Microgrid (MG) having DGs is ensured by both the grid connected and islanded mode of operations. The selection of mode of operation of a MG is based on technical and economic factors. The intentional islanding of the MG depends on the prevailing operating condition of grid and MG. These conditions are sensed at point of common coupling (PCC) and accordingly the switching to the mode is performed. This paper presents the detection and evaluation of operating conditions of the network at PCC, and switching to Islanded mode on the need. The conditions have been categorized for the decision of intentional Islanding. The cases under each category have been simulated on Real Time Digital Simulator (RTDS®). The results have also been analyzed.

微电网的有意孤岛化
现有电网和微电网(MG)之间的电力供应的可靠性和可持续性是通过并网和孤岛运行模式来保证的。机组运行方式的选择主要基于技术经济因素。MG的故意孤岛取决于电网和MG的现行运行状况。在共耦合点(PCC)检测这些条件,并相应地执行模式切换。本文介绍了PCC网络运行状态的检测和评估,并根据需要切换到孤岛模式。对决定故意离岛的条件进行了分类。在实时数字模拟器(RTDS®)上对每一类案例进行了仿真。并对结果进行了分析。
