TL;DR: An open-source extendable model that is synthetic but nevertheless provides a realistic representation of the actual energy grid, accompanied by open- source cross-domain data sets is released and the regional disparity of load shedding is uncovered.
Abstract: Unprecedented winter storms that hit across Texas in February 2021 have caused at least 69 deaths and 4.5 million customer interruptions due to the wide-ranging generation capacity outage and record-breaking electricity demand. While much remains to be investigated on what, how, and why such wide-spread power outages occurred across Texas, it is imperative for the broader macro energy community to develop insights for policy making based on a coherent electric grid model and data set. In this paper, we collaboratively release an open-source extendable model that is synthetic but nevertheless provides a realistic representation of the actual energy grid, accompanied by open-source cross-domain data sets. This simplified synthetic model is calibrated to the best of our knowledge based on published data resources. Building upon this open-source synthetic grid model, researchers could quantitatively assess the impact of various policies on mitigating the impact of such extreme events. As an example, in this paper we critically assess several corrective measures that could have mitigated the blackout under such extreme weather conditions. We uncover the regional disparity of load shedding. The analysis also quantifies the sensitivity of several corrective measures with respect to mitigating the severity of the power outage, as measured in Energy-not-Served (ENS). This approach and methodology are generalizable for other regions experiencing significant energy portfolio transitions.

TL;DR: A flexible model for microgrid formation in the integrated electricity-gas system by optimal sizing, siting and operation of combined heat and power (CHPs) in order to improve the system operation/resilience and reduce the operational/energy cost is presented.

TL;DR: In this article, the authors look at the similarities between the 2003 blackout and the Western System collapse of 1996 and show that the August 14 collapse resulted from system overloading that led to voltage deterioration in the system and consequently a fast collapse, similar to the July 2, 1996 collapse.
Abstract: This paper looks at the similarities between the August 14, 2003 blackout and the Western System collapse of 1996. It was shown that the August 14 collapse resulted from system overloading that led to voltage deterioration in the system and consequently a "fast" collapse, similar to the July 2, 1996 collapse.

TL;DR: In this paper, the coordination of a load-shedding scheme for a large industrial customer with several cogenerator units was developed. But the main focus was on the generator protection scheme.
Abstract: This paper develops the coordination of a load-shedding scheme for a large industrial customer with several cogenerator units. A detailed description of each design procedure is included. The loads are tripped by the underfrequency relays, to prevent the power system from collapse when the plant becomes isolated, due to a utility service outage. Different system fault cases have been selected to derive the proper formulation of a load-shedding scheme, according to the historical operation records. The key factors, such as frequency settings, number of load-shedding steps, size and location of the loads to be tripped, relay time delay, and the coordination with the generator protection scheme, were examined through the simulation of the transient stability program. The proper load-shedding scheme has been designed, and the related hardware has been installed in the plant, to keep the system from blackout when the disturbance occurs.

TL;DR: In this article, a blackout risk assessment method is proposed considering the effects of cascading outages, the active power and frequency response of the system, and the Monte Carlo Simulation (MCS) is used to analyze the risk of blackouts by generating rare event scenarios.
