Working principle of high temperature solar energy independent energy storage power station

Can thermal energy storage systems be used for CSP plants?

Thermal energy storage systems for CSP plants have been investigated since the start of XXI century , . Solar power towers have the potential for storing much more heat than parabolic trough collectors .

Why is thermal energy storage a key cross-sectional technology?

Thermal energy storage (TES) systems correct this mismatch between the supply and demand of the thermal energy. Hence, TES is a key cross-sectional technology with growing present and future importance for utilizing volatile renewable sources (e.g., wind and photovoltaics) and energy efficiency improvements.

What is high-temperature solar?

High-temperature solar is concentrated solar power (CSP). It uses specially designed collectors to achieve higher temperatures from solar heat that can be used for electrical power generation. In this chapter, we discuss different configurations of concentrating collectors and advancements in solar thermal power systems.

What is a solar thermal power plant (STPP)?

The heat is transformed into a turbine through a heat exchanger and electrical energy is generated. A Solar Thermal Power Plant (STPP) has higher efficiency than a solar PV plant or a low-temperature electricity generator. The other advantage is that a STPP can store heat energy for a longer time than a photovoltaic plant.

How can high-temperature thermal energy be stored?

The high-temperature thermal energy can be directly stored with a low-cost heat transfer media, such as molten salt or particles, and, when needed, transfer into electricity through a thermodynamic power cycle.

How does concentrated solar power work?

The working principle of concentrated (or concentrating) solar power is very simple: direct solar radiation is concentrated in order to obtain high temperature (approximately between 500 and 1000 °C) thermal energy that is transformed into electrical energy .
