Analytical Method for Power Grid Dispatching Centralized Thermal Storage to Reduce Wind Abandoned Rate

In order to achieve clean heating and reduce the rate of abandoned wind, the northern region has invested in various heat storage devices, especially the large-capacity heat storage devices invested by thermal power plants to improve adjustment flexibility. The power consumption calculation method of large-capacity heat storage device invested by thermal power plants and the calculation method of abandoned wind power in power grid were proposed. Moreover, the relationship between the input timing of the heat storage device and the timing of abandoning wind was researched, and the delay of deep peak shaving of the unit after the input of the heat storage device was discussed. The actual data show that the input timing of the heat storage device and the timing of abandoning wind have a demonstration effect on the consumption of wind power through thermal storage in the northern region.
