TL;DR: In this article, the authors evaluate several utility-scale energy storage technology options for their usage as regulation resources and select flywheels, pumped hydro electric power (or conventional hydroelectric power) plant and sodium sulfur or nickel cadmium batteries as candidate technologies for the Wide Area Energy Management System (WAEMS) project.

TL;DR: In this article, a wide area energy storage and management system (WAEMS) is proposed to mitigate additional intermittency and fast ramps that occur at higher penetration of intermittent resources, including wind genera-tion, in the Bonneville Power Administration (BPA) and the California Independent Sys-tem Operator (California ISO) control areas.

TL;DR: The experience gained, and the technical solutions developed in this PhD project can be utilized in such demonstration projects, and in a longer timescale contribute to forming the basis for further increase in the renewable energy sources penetration in the power system.

TL;DR: A survey of possible and likely new measures which can ensure a reliable and economic operation of the power system with large scale distributed generation mainly from renewable sources, particularly wind power.

TL;DR: The objective of the control algorithm is to respond to the control signals from the different system operators, whilst optimizing the hydro power plant operation by reducing the tear and wear on the mechanical parts and improving the energy efficiency of the plant.
