Concentrating solar power (CSP) is a renewable energy technology that uses mirrors to concentrate solar rays onto a receiver. The receiver converts radiation to thermal energy,
To increase the solar share of the plant a thermal energy storage is used. All solar-hybrid power plants were modeled with different sizes of solar fields and different storage capacities. Therefore for a solar field with solar multiple 1 (SM1)1 no storage is used, for SM2 a storage capacity of 7.5h (i.e. 7.5h of nominal load operation at design point conditions) and for SM3 a storage capacity

However, the combined effects of key design parameters for sizing the solar tower power plants, including design direct normal irradiance, solar multiple and thermal storage hours, on
The fluid is stored in two tanks—one at high temperature and the other at low temperature. Fluid from the low-temperature tank flows through the solar collector or receiver, where solar energy heats it to a high temperature, and it then flows to the high-temperature tank for storage.
The storage capacity is currently limited to 8 h, however, in few years is expected to reach up to 12 h decreasing its levelized cost of electricity; from 14.2 ($/kWh) in 2015 to 9 ($/KWh) in 2020 .
Thermal energy storage provides a workable solution to the reduced or curtailed production when sun sets or is blocked by clouds (as in PV systems). The solar energy can be stored for hours or even days and the heat exchanged before being used to generate electricity .
In summary, the power tower concentrating solar power plant, at the heart of which lies the heliostat, is a very promising area of renewable energy. Benefits include high optical concentration ratios and operating temperatures, corresponding to high efficiency, and an ability to easily incorporate thermal energy storage.
A solar power tower, also known as 'central tower' power plant or ' heliostat ' power plant, is a type of solar furnace using a tower to receive focused sunlight. It uses an array of flat, movable mirrors (called heliostats) to focus the sun's rays upon a collector tower (the target).
These include the two-tank direct system, two-tank indirect system, and single-tank thermocline system. Solar thermal energy in this system is stored in the same fluid used to collect it. The fluid is stored in two tanks—one at high temperature and the other at low temperature.
