6 FAQs about [Energy storage peak regulation benefit analysis of thermal power plants]
What is the optimal energy storage allocation model in a thermal power plant?
On this basis, an optimal energy storage allocation model in a thermal power plant is proposed, which aims to maximize the total economic profits obtained from peak regulation and renewable energy utilization in the system simultaneously, while considering the operational constraints of energy storage and generation units.
Do I need to charge the energy storage system for peak shaving?
The dispatching department calls it for free. When the output of thermal power unit is between (1 − k) Pthe and 0.5 Pthe, the thermal power unit has the ability for peak shaving. At this time, there is no need to charge the energy storage system for peak shaving. To avoid deep discharge in energy storage system, SOCmin is set to 20%.
What is a thermo-economic analysis of integrated bidirectional peak shaving system?
Thermo-economic analysis of the integrated bidirectional peak shaving system consisted by liquid air energy storage and combined cycle power plant Energy Convers. Manag., 234 ( 2021), Article 113945 Load shifting of nuclear power plants using cryogenic energy storage technology
Can peak regulation reduce environmental pollution and operating pressure in TPUs?
Among them, the changes in carbon emission quality, total peaking cost of TPUs, and power supply ratio of new energy are the most significant. The results demonstrate that the incorporation of a CSP plant and a DPR unit for peak regulation can effectively mitigate both environmental pollution and operating pressure in TPUs.
How to improve peak regulation capability of CSP plant?
The peak regulation ability of the CSP plant is limited by illumination conditions and TES capacity in the conversion process of light-heat-electricity. To further improve the peak regulation capability, the integration of the CSP plant with EH is proposed to actively join the power system operation.
Can a concentrated solar power plant with an electric heater join peak regulation?
Therefore, a concentrated solar power (CSP) plant equipped with an electric heater (EH) is implemented to join the peak regulation, and the joint peak regulation strategy between thermal power units (TPUs) and a CSP plant is proposed. Firstly, the peak regulation principle of a CSP plant with EH is analyzed in detail.
