Modeling and analysis of the CERTS microgrid with natural gas powered distributed energy resources

Distributed energy resources (DERs) powered by natural gas engines are becoming more popular in several nations. This paper presents the modeling and analysis of engine fuel map limits on natural gas powered DERs installed at the CERTS Microgrid. A physics-based approach is used for correct modeling of the limiting conditions in DERs. The distinguishing characteristics of both inverter-based and synchronous generator-based DERs are established. Furthermore, the performance of CERTS Microgrid under is shown for different case studies of islanded operation.
