Under the new power system in China, both the generation and consumption
sides have the characteristics of flexibility, randomness, and volatility,
making it difficult for the existing power grid structure to achieve unified
resource scheduling.
On the power generation side. Traditional power plants such as thermal
power plants have flexible site selection. During the working process, they can
effectively dispatch power generation units based on the real-time electricity
demand of users, achieving a balance between power supply and demand. However,
the disadvantage is the high pollution of non renewable energy.
As traditional power plants are gradually replaced by new energy power
plants such as hydropower, wind power, and photovoltaics, there is no need to
worry about pollution. However, new energy power plants are limited by resource
abundance, and the disadvantages of randomness, intermittency, and volatility
will inevitably become prominent.
Water resources can be divided into rain and drought, light can be
different in spring and winter, and wind energy can change significantly in
real-time. Coupled with the differences in longitude and latitude where power
plants are located, China has a vast territory, and ensuring the stable
operation of the power grid is a complex task.
In terms of electricity consumption. New energy vehicles, charging
stations, and household energy storage equipment have seen significant growth in
recent years, with different user regions and varying levels of development. The
density of electrical equipment layout varies greatly, with obvious randomness
and volatility, making it difficult to achieve unified scheduling.
In addition, in recent years, the energy storage market has been booming,
and rooftop photovoltaics have also greatly developed. The electricity
consumption side has transitioned from simple electricity consumption to a
bidirectional structure that balances electricity consumption and power
generation. The complexity of resources on the electricity consumption side has
increased, making it difficult to accurately adjust the power grid.
