The notice outlines subsidy policies for new energy storage, including the following: Independent energy storage capacity will receive a capacity compensation of 0.2 CNY/kWh discharged, gradually decreasing by 20% annually starting from 2024 until 2025.
In recent years, the power load as well as the peak–valley load difference has increased greatly, causing the shortage of peak-regulation capacity in urban power grids. Furthermore, with the increasing penetration of renewable energy generation (Ahmad et al., 2021), the peak-regulation insufficiency issue becomes even more serious and complicated.
Principle of the evaluation method The peak-regulation capability of a power grid refers to the ability of power supply balancing with power load, especially in the peak load and valley load periods. Specifically, the adjustment range of power supply in one day should be high enough to reach the peak load and low enough to reach the valley load.
In this paper, nuclear power is assumed to have no peak-regulation capacity. For renewable energy, the Renewable Energy Act of People’s Republic of China stipulates that renewable energy generation can be scheduled in priority during the power grid operation.
It may lead to establish novel peak-regulation services in future Chinese power grid. Moreover, it is worthy to study the modification method for the derived unit commitment results, which can further improve the accuracy of the proposed evaluation method.
