Applications include stability, fault, harmonic, dynamic, and interconnection studies. The GFM inverter can be modeled as: droop- based, virtual synchronous machine (VSM)-based, dispatchable virtual oscillator (dVOC)-based, or a PLL-based. 2022-04-11T00:00:00Z http://item.bettergrids.org/handle/1001/748 Title: WRDB: Wind Resource Database (US & International) Abstract: The Wind Resource Database (WRDB) is a collection of modeled wind resource estimates for the United States and various countries around the globe of various lengths up to over 20 years. Most of the data are available in 5-minute (min.) intervals at 2-kilometer (km) spatial resolution. For the United States, uncertainty estimates are also provided. For a given location covered by a dataset, it is possible to see the wind resource either at a given time or averaged over a certain period. We also provide several other meteorological quantities needed for wind energy research. 2020-01-01T00:00:00Z http://item.bettergrids.org/handle/1001/746 Title: LA100: The Los Angeles 100% Renewable Energy Study and Equity Strategies Abstract: Released in March 2021, the groundbreaking Los Angeles 100% Renewable Energy Study (LA100) found that LA can achieve reliable, 100% renewable power as early as 2035. 2021-03-01T00:00:00Z http://item.bettergrids.org/handle/1001/744 Title: Virtual Synchronous Machine Grid-Forming Inverter Model Specification (REGFM_B1) Abstract: The model specifications of droop-based GFM (REGFM_A1) and VSM-based GFM (REGFM_B1) have been adopted by WECC. The model specifications can be accessed through the following links. The REGFM_A1 model has already been released in major commercial transient stability simulation tools including PTI-PSS®E, GE-PSLF, PowerWorld Simulator, and TSAT. The REGFM_B1 model is expected to be released in those tools soon. 2024-06-01T00:00:00Z
