“…In a previous work supported by U.S. Department of Energy Solar Energy Technologies Office [12][13][14][15][16][17][18], the high PV cases for the ERCOT system were developed in PSS ® E for 5%, 25%, 45%, and 65% PV with 15% wind. The high PV cases were developed by replacing conventional synchronous generators with PV power plants, with a sequence of replacement starting from coal power plants, then gas power plants, and further nuclear power plants.…”

This study was performed to assess the impact of high photovoltaic (PV) penetration on transient stability using a series of hypothetical models of the ERCOT system. This was done by calculating the critical clearing time (CCT) when faulting various busses. Varying levels of PV penetration were used to study the system transient stability. For each case 15% wind penetration was also included. It was found that under the PV volt/Var control with plant-level GE SolarControl settings, PV penetration at lower level can slightly improve the transient stability in the ERCOT system model. However, at approximately 54% penetration of renewables (39% PV and 15% wind), transient stability starts to show declining trend. This value has slight variance depending on PV distribution.

“…Power grid reliability and security is important for societies [1][2][3][4][5][6][7][8][9][10]. The increase of renewable generation, such as wind and solar, and other resources including energy storage and controllable load, are changing how power grids are being operated [3,[11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. The development of advanced measurement and control systems has significantly improved power system reliability, resiliency, and efficiency .…”

Cyber security is important of power grids to ensure secure and reliable power supply. This paper presented a cyber- secure framework for power grids based on federated learning. In this framework, each entity, which may be a distribution/transmission/generation service provider or even a customer, can contribute to the overall system immunity and robustness to cyber-attacks, while not required to share local data, which may have privacy, legal and property concerns. The main idea is to use the federated learning framework to share the knowledge learned from local data instead of sharing power grid data itself. With complete knowledge learned from all data from the power grid, each entity is better positioned to defend the cyber-attacks and improve power grid resiliency. Future work on applying this federated learning based framework in power systems is also discussed.

“…The displacement of synchronous generators with PV has direct impacts on the system inertia level and frequency regulation capability. Many power systems starts to notice the risks of insufficient system inertia and frequency regulation resources due to the increase of PV and other nonsynchronous renewable generation [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30], largely thanks to the deployment of wide-area synchrophasor measurement systems .…”

This paper studied the solar PV frequency control in the U.S. Eastern Interconnection (EI) and Texas Interconnection (ERCOT) systems. The studied frequency control approaches include droop frequency control, inertia control, and droop-inertia-combined frequency control. The control effects of different frequency controls of PV in the EI and ERCOT are studied using actual high PV penetration interconnection grid models to provide suggestions to the future revision of future PV frequency control standards.
