Thermoelectric power generation: from new materials to devices
Power boosting mode – solar aided heating resulting in additional power generation for the same fuel consumption as in the reference power plant. Note that most modern steam power plant can handle increased steam mass flows (boosted power output) with up to around 10% above the rated turbine capacity ( Petrov et al., 2012 ).
– Solar collectors do not need any fuels for operation. Cons: – High cost of investment. – The solar thermal plant requires a large quantity of water, which may be an issue in areas with water scarcity. – There are frequent innovations in the solar energy industry, so the technology may become outdated very soon. Conclusion
Photo thermal power generation, as a renewable energy technology, has broad development prospects. However, the operation and scheduling of photo thermal power plants rarely consider their internal structure and energy flow characteristics. Therefore, this study explains the structure of a solar thermal power plant with a …
