The existing approaches for evaluating peak-regulation capability of power grid contains deterministic and probabilistic methods. In Yang et al. (2010), a deterministic model was proposed to calculate the maximum capacity of downward peak-regulation considering the constraints of unit parameters.
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.
Grid-side energy storage is distributed at critical points in the power grid, providing various services such as peak shaving and frequency regulation. User-side energy storage refers to storage systems installed on the user side, such as households, businesses, and factories, enhancing the flexible regulation capacity of load-side users.
Also, the peak-regulation capability determines the renewable energy consumption and power loads of cities by mitigating power output fluctuation in the regulation process of power grid.
It frequently happens in current Chinese power grids especially during evening that the system operator must shut down some units to balance the valley load. Other countries or urban regions also face the same peak-regulation problem.
The development of pumped storage and new energy storage in Central China shows a trend of coexistence and complementarity, which is mainly due to the great importance of energy structure optimization and power system regulation capacity in the region.
