What is a CHP-type CSP power station?

The CHP-type CSP power station consists of the solar field, thermal energy storage (TES) tank, thermal cycle system, and back-pressure turbine (BT). The transfer of energy between these components primarily relies on heat transfer fluids. The basic operating process is as follows:

What are phase change energy storage materials?

Phase change energy storage materials have been widely used in building energy-saving projects to achieve functions such as temperature regulation, waste heat storage, and assisting in the integration of new energy sources [, ].

Are PV and CSP power stations economically feasible?

For the purpose of comparing the economic feasibility of each strategy, this paper assumes that both the PV and CSP power stations employ the same scale of solar fields. The photovoltaic (PV) and concentrating solar power (CSP) stations have the same photovoltaic conversion efficiency, and their rated capacities are both 50 MW.

How to design a thermal energy storage building with phase change material?

Given the solar irradiance E and outdoor temperature, the thermal energy storage building with phase change material is modeled with five parts: the air inside the phase change wall, the phase change material, the indoor air, the inner surface of the phase change wall, and the inner surface of other wall components.

What is the difference between CHP and phase-change energy storage?

CHP units help improve the output efficiency of solar thermal power generation, while building phase-change energy storage helps alleviate the constraints of the unit's thermal-electric ratio.

How much does a cogeneration-type CSP station cost?

However, employing the cogeneration-type CSP station reduces the equivalent annual cost to 180,495.59 million yuan, lower than traditional strategies and PV stations. At the same time, adopting the strategy proposed in this paper can further reduce the equivalent annual cost to the lowest level.
