This article reviews power system flexibility assessment, which is necessary to ensure both
instantaneous stability and long-term security of supply under high penetrations of variable …

Reliable and stable power system operation requires flexibility, in addition to capacity
adequacy. Traditional system components either have limited flexibility to suppress …

In this work we document the development of cost and performance projections for utility-
scale lithium-ion battery systems, with a focus on 4-hour duration systems. The projections …

With declining costs of battery storage, there is growing interest to deploy them in power
systems to provide multiple grid services that directly support integration of variable …

Providing peaking capacity could be a significant US market for energy storage. Of particular
focus are batteries with 4-h duration due to rules in several regions along with these …

Rising penetrations of variable renewable energy (VRE) in power systems are expected to
increase the curtailment of these resources because of oversupply and operational …

This paper analyzes different models for evaluating investments in energy storage systems
(ESS) in power systems with high penetration of renewable energy sources. First of all, two …

Electrification of end-use services in the transportation, buildings, and industrial sectors
coupled with decarbonization of electricity generation has been identified as one of the key …

The future development of the US electricity sector will be shaped by technological,
economic, and policy drivers whose trajectories are highly uncertain. In this article, we …

Southern Africa faces the dual challenge of providing affordable energy to meet rapidly
growing electricity demand while limiting carbon emissions and socio-environmental …
