Wind power consumption coordination control method based on fused magnesium load

Abstract

The invention discloses a wind power consumption coordination control method based on fused magnesite load. The method comprises the following steps of: predicting a day-ahead wind power output curve, taking the fused magnesite load as a controllable load during day-ahead scheduling on the basis of the actual production and operation conditions of the fused magnesite load, regulating and controlling a high-energy-consumption load in a wind curtailment period, taking the minimum sum of whole-day wind curtailment amounts in the next day as an optimization target, introducing upper and lower limit constraints of the power of the fused magnesium load, an adjustment duration constraint, an adjustment frequency constraint and operation constraints of wind power and thermal power into constraint conditions, and conducting optimization calculation to obtain the adjustment amount of the fused magnesium load in each time period so as to realize wind power consumption. According to the invention, the load operation characteristics and the production process of the fused magnesite are fully utilized, a coordination control strategy for changing the load curve of the fused magnesite is provided, an existing fused magnesite controllable load on a load side is utilized under the condition that other auxiliary equipment is not increased, a positive effect on reduction of a wind curtailment electric quantity is achieved, and the utilization rate of wind power is increased.

Description

technical field [0001] The invention relates to the technical field of wind power accommodation capacity methods, in particular to a coordinated control method for wind power accommodation based on fused magnesium load. Background technique [0002] With the shortage of fossil energy such as coal and oil and the impact of environmental pollution caused by the use of a large amount of fossil energy, human beings have paid enough attention to the development of renewable energy. my country's total energy consumption continues to increase and maintains a rapid growth rate. The resulting pollution emissions and ecological construction are very prominent. Therefore, building a safe, clean and sustainable energy system has become a key issue for my country's energy development. inevitable requirement. In recent years, with the joint efforts of the government, power generation companies, power grid companies and users, my country's new energy development has made great achievements...
