In a solar tower plant, a single receiver is used and the power collected by the heliostat field is strongly coupled to the tower height and its location with respect to the field. The literature available focuses largely on the component-level details of the heliostat field, ray-tracing mechanisms, receiver heat transfer analyses, etc.

The solar tower power plant Solar Two, for example, uses a two-tank direct storage system consisting of a hot-salt and a cold-salt storage tank. The storage fluid consists of an eutectic salt mix of sodium nitrate (NaNO 3 ) and potassium nitrate (KNO 3 ) in the proportion 60% NaNO 3 + 40% KNO 3, with a total weight of 1500 t.
Concentrating solar power (CSP) plants offer dispatchable power by integrating thermal energy storage (TES) and their costs have been reducing …
