Solar power works by converting energy from the sun into power. There are two forms of energy generated from the sun for our use – electricity and heat. Solar is an important part of NESO’s ambition to run the grid carbon zero by 2025.
The PV power system converts solar energy directly into electricity by solar cells. In concentrated solar power (CSP) generation systems, the working fluid is heated by the concentrated solar light and then changed to be high-temperature steam, which can drive the steam turbine to produce electricity [10, 11].
The multi-energy hybrid power systems using solar energy can be generally grouped in three categories. The first category is the hybrid complement of solar and fossil energies, including solar-coal, solar-oil and solar-natural gas hybrid systems.
There are mainly two methods of solar power generation, which are solar PV [, , ] and solar thermal power generations [8, 9]. The PV power system converts solar energy directly into electricity by solar cells.
Here, in this study, solar energy technologies are reviewed to find out the best option for electricity generation. Using solar energy to generate electricity can be done either directly and indirectly. In the direct method, PV modules are utilized to convert solar irradiation into electricity.
The utilization of solar heat plays an important role in the solar assisted coal-fired power plants, and the coupling of solar thermal and coal-fired power system is the focus of current research. The solar energy usually be used for preheating and reheating in solar-aid coal-fired power plants.
