6 FAQs about [Prices of energy storage and thermal power peak load regulation]
What is deep peak regulation of thermal power plants?
Therefore, deep peak regulation (DPR) of thermal power plants remains one of the main peak regulation methods for the source side in China. The lower reserve capacity of thermal power plants is used to provide peak regulation power generation rights for renewable energy sources such as wind and solar energy.
Does thermal power unit peaking affect energy storage life?
However, it is important to acknowledge that deep peaking operation in thermal power units and the associated loss of storage life lead to increased operating costs for the system. Hence, it is of utmost significance to accurately assess the degradation of energy storage lifespan and the cost associated with thermal power unit peaking.
Do thermal power units participate in peak regulation auxiliary services?
Owing to China’s energy structure, thermal power accounts for nearly half of the country’s installed power generation capacity. Although the willingness of thermal power units to participate in peak regulation auxiliary services is low, we propose a peak regulation cost compensation and capacity-proportional allocation mechanism.
Can thermal power units improve peaking capacity?
The conventional thermal power unit has proven inadequate for meeting the demands of large-scale wind and solar grid integration. To address this issue, the combination of energy storage and deep peaking operation in thermal power units has emerged as a promising approach to enhance the peaking capacity of the system .
What is a peak regulation model?
The peak regulation model was constructed with the aim of minimizing fluctuations in the thermal power output, lowering the operating cost of the system, and minimizing the abandonment of renewable energy. Finally, CPLEX was used to solve the modified IEEE 30-bus system.
Why do thermal power units need a deep peak shaving?
If the load demand is maintained at the current level, the growing capacity of renewable energy sources gradually reduces the space for the output of traditional thermal power units and results in an increasing reliance on the deep peak shaving of thermal power units.
