基于电力电子的分布式能源（DER）正被越来越多地部署，以实现高能源效率、电能质量以及电力系统运行和控制的灵活性。它们促进了对各种能源的获取，包括可再生能源、燃料电池、微型涡轮机、变速发动机发电机组等。然而，最近在电力可靠性技术解决方案联盟（CERTS）微电网进行的测试表明，它们在混合源微电网中的部署可能会在极端事件期间导致级联崩溃。在PSCAD/EMTDC软件中建立了两种类型的DERs的仿真模型，并用实验测试结果进行了验证。在IEEE 33节点测试系统上，利用验证模型研究了大规模混合源微电网的级联崩溃问题。本文评估了三种替代技术，以防止在大规模微电网的级联崩溃所造成的快速作用的电力电子为基础的DER。
Power electronics-based distributed energy resources (DERs) are being increasingly deployed for achieving high energy efficiency, power quality, and flexibility of power system operation and controls. They facilitate access to various kinds of energy sources including renewables, fuel cells, microturbines, variable speed engine-generator sets, etc. However, recent tests carried out at the Consortium of Electric Reliability Technology Solutions (CERTS) Microgrid have indicated that their deployment in the mixed source microgrid can cause a cascading collapse during extreme events. Simulation models of two types of DERs are developed in PSCAD/EMTDC software and validated with the experimental test results. The validated models are used to study a cascading collapse problem in a large-scale mixed source microgrid on the benchmark IEEE 33-bus test system. This paper evaluates three alternative techniques to prevent the cascading collapse in the large-scale microgrid caused by fast-acting power electronics-based DERs.
