For stationary application, grid-level large-scale electrical energy storage (GLEES) is an electricity transformation process that converts the energy from a grid-scale power network into a storable form that can be converted back to electrical energy once needed .
However, PV generation poses significant challenges to generation dispatch, spinning reserve strategies, and power system stability due to its intermittent and variable nature, lack of inertia, and asynchronous synchronization with demand. Battery Energy Storage Systems (BESS) can help utility networks integrate increasing amounts of solar PV.
Because we consider the needs of both distribution and transmission system operators, we refer to this formulation as vertical and horizontal planning of energy storage systems, as opposed to horizontal planning that includes a single voltage level only.
Battery energy storage technology is an effective approach for the voltage and frequency regulation, which provides regulation power to the grid by charging and discharging with a fast response time (< 20 ms) that is much shorter than that of traditional energy storage approaches (sec–min) [10, 13].
