Description

Technical Field

[0001] The present invention relates to the technical field of power generation, and in particular to a power grid peak regulation method and device. Background Art

[0002] Grid peak load regulation refers to a method of maintaining stable operation of the power grid by adjusting the balance between power generation and load when the load of the power system reaches its peak. Various measures are used to cope with the power demand during the load peak to ensure the stable operation of the system. In the power system, the load usually fluctuates over time. In certain specific time periods, such as the peak industrial production period during the day or the peak air conditioning power consumption period in hot summer weather, the power grid may face greater load pressure, and even the load may reach a peak, which may cause the power grid to be overloaded or insufficient. Therefore, in order to cope with these load peaks, the power grid needs to take a series of measures to ensure that it can meet the power needs of users and maintain the stable operation of the power grid. The goal of the peak load regulation strategy is to balance the load demand through various technologies and measures without increasing the system capacity to ensure the reliability and stability of the system.

[0003] However, traditional power grid peak-shaving methods usually only focus on how to achieve peak-shaving, but do not pay attention to how to determine the current load level of the power grid and how to accurately implement peak-shaving measures based on the load level of the power grid. As a result, it is impossible to quickly peak-shave the power grid, and it is difficult to ensure the balance between power supply and power consumption during high-load periods. The imbalance between power supply and demand leads to frequent power grid failures or power outages, and the reliability and stability of the power grid cannot be ensured. Summary of the invention
