The invention provides a method of increasing a wind power absorption capability. The method comprises the following steps of acquiring wind power output data of a second day, and according to the wind power output data and load data, generating a first day-ahead scheduling plan containing wind and power; acquiring whether there is wind curtailment, and if there is no wind curtailment, sending the first day-ahead scheduling plan to a thermal power plant and a wind power plant; if there is the wind curtailment, using a unit combination model containing a translatable load to generate a second day-ahead scheduling plan; acquiring new wind curtailment appearance time distribution and a related wind curtailment electric quantity, sending a second scheduling plan to the thermal power plant, sending translation load information to a high energy-loaded enterprise containing the translatable load and sending the wind curtailment appearance time and the wind curtailment electric quantity to the high energy-loaded enterprise containing an owned power plant, wherein the high energy-loaded enterprise containing the owned power plant acquires an absorbable wind curtailment electric quantity; and according to the received absorbable wind curtailment electric quantity, forming a third day-ahead scheduling plan of the wind and power and sending the third day-ahead scheduling plan to the wind power plant.
Description
technical field [0001] The invention belongs to the technical field of electric power system control, and in particular relates to a method for improving wind power accommodation capacity by utilizing high energy load. Background technique [0002] my country's wind power continues to develop rapidly and has become the fourth largest power source in my country. In recent years, there have been more and more serious wind curtailment phenomena, especially in the western region, which seriously restricts the further development of wind power. In 2014, the wind curtailment rates in Gansu, Inner Mongolia and Xinjiang reached 11%, 9% and 15% respectively, higher than the national average of 8%. [0003] However, according to the existing traditional unit combination model, it is difficult to deal with wind curtailment, resulting in energy waste. The high energy load has a large load, and it also has a self-provided power plant, which has the potential to accommodate curtailed wi...
