This paper presents a novel fault current management (FCM) technique for radial distribution systems with embedded inverter-based distributed generators (IB-DGs). At the point of connection to a power system, many distributed generators (DGs) require power electronic (PE) interfaces, which are normally idle during faults. The proposed FCM method employs these PE interfaces for control of the fault...
Using production-cost model (PLEXOS), we simulate the Western Interchange (WECC) at several levels of the yearly renewable energy (RE) generation, between 13% and 40% of the total load for the year. We look at the overall energy exchange between a region and the rest of the system (net interchange, NI), and find it useful to examine separately (i) (time-)variable and (ii) year-average components of...
The integration of increasing amounts of intermittent renewable generation whose reliability contributions are significantly different than those of the historically dispatchable thermal generating units is important to future electric generation planning. With relatively small amounts of intermittent generation, reliability impacts may not be detectable; however, as renewable integration goals continue...
This paper describes enhancements to ATC's cascading study criteria and the implementation of a fast automated process using POM/OPM software for conducting comprehensive steady state multiple element contingency screening and cascading analysis, finding mitigations to restore the system to be within emergency and/or normal performance limits, and automatically tabulating significant results and summaries...
High penetration of wind generation causes concerns regarding the frequency stability if wind plants do not provide inertial response. Extensive research has been conducted to investigate the design of controller to facilitate wind plants to provide synthetic inertia. However, the economic value of synthetic inertia provision from wind plants has not yet been understood. This paper develops a methodology...
