This paper provides a survey of applying electric energy storage (EES) for helping integrate large-scale variable renewable electricity sources (VRES), such as wind and solar power, into electric power systems. The integration of VRES introduces significant uncertainty into the operation and planning of electric power systems.
As electricity power grids transition to variable renewable energy sources, long-duration energy storage (LDES) will be increasingly important to address long-term, seasonal intermittency in renewable generation.
The high penetration of variable renewable energy, such as wind power and photovoltaic, increases the challenge of balancing the power system. Energy storage technology is regarded as one of the key technologies for balancing the intermittency of variable renewable energy to achieve high penetration.
Options to absorb large shares of variable energy into the grid include using storage, improved interconnection between different variable sources to smooth out supply, using dispatchable energy sources such as hydroelectricity and having overcapacity, so that sufficient energy is produced even when weather is less favourable.
It is understood that VRE increases the need for flexible generation and operating reserves, which can be met by energy storage. However, the value of energy storage is best captured when selling to the entire grid instead of any single source. Evaluating the role of storage and DR with VRE sources
Electric energy storage (EES) is a tool for mitigating the impacts of variable renewable energy sources (VRES) uncertainty (Abbey and Joos, 2007, Lu et al., 2008). Several criteria are analyzed when considering and choosing EES technologies for a specific application (Chen et al., 2009, Shoenung, 2001, Bo et al., 2008).
