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.
Under the worldwide carbon neutralization targets, concentrating solar power (CSP) is arousing great attention. With the thermal energy storage (TES), CSP is friendly to the power system operation by supplying controllable renewable energy. The capacities of its solar field and TES are essential parameters for maximizing the profit of a CSP plant.
The configuration of the CSP plant is optimized through the first-order optimality conditions on the profit function. The optimal configuration of CSP with high renewable energy is provided in the case study. Under the worldwide carbon neutralization targets, concentrating solar power (CSP) is arousing great attention.
2.3. Thermo-economic data Regarding efficiency values and as a general overview, it can be highlighted that thermal efficiency (solar to mechanical) is estimated between 30% and 40% for solar power towers.
This overview will focus on the central receiver, or “power tower” concentrating solar power plant design, in which a field of mirrors - heliostats, track the sun throughout the day and year to reflect solar energy to a receiver that absorbs solar radiation as thermal energy.
The efficiency (i.e. the ratio of electricity to solar energy) is about 14-16% and the capacity factor is on the order of 25-30%, depending on the location. Some PT and ST plants have molten salt thermal storage systems with storage capacities of 6-15 hours, which increase the plant capacity factorsto over 40% and 70%, respectively.
