What is solar thermal power generation? What are its classifications?

Solar thermal power generation, also known as focused solar power generation (CSP), focuses the direct sunlight through a large number of mirrors, heats the working medium, generates high-temperature and high-pressure steam, and drives the steam turbine to generate electricity. Although human beings have used solar energy for more than 3000 years, it has been less than 400 years since it was used as energy and power. Since the beginning of17th century, according to the development and application of solar energy utilization, the development process of solar energy utilization in the modern world can be roughly divided into eight stages. Solar thermal power generation is usually called concentrated solar power generation. Unlike traditional power stations, they generate electricity by collecting solar radiation and converting it into high-temperature steam to drive steam turbines. At present, solar thermal power generation can be divided into solar trough power generation according to solar energy collection methods; Solar tower thermal power generation; Solar dish thermal power generation.
