Abstract

The invention discloses a wind power-containing electric power system spinning reserve optimal configuration method considering demand response. The method comprises steps of 1, performing modeling analysis calculation according to uncertainty of wind power output and a load to obtain initial spinning reserve capacity of a power system; 2, performing calculation to obtain load side reduction spinning reserve capacity according to an interruptible load model and a translatable load model; 3, analyzing the initial spinning reserve capacity and the reduced spinning reserve capacity to determine the optimized spinning reserve capacity; and 4, solving the optimized spinning reserve demand by adopting a Matlab toolbox YALMIP programming solving method to obtain optimal configuration of the spinning reserve demand. The method is advantaged in that stable operation of the power grid is guaranteed, operation economic performance of an electric power system can be improved, the spinning reservecapacity is provided, wind power consumption is promoted, and high engineering applicability is achieved.

Description

technical field [0001] The invention relates to the technical field of electric power automation, in particular to a method for optimizing configuration of spinning reserve of electric power system including wind power taking into account demand response. Background technique [0002] The inherent randomness and volatility of wind power seriously affect the stable operation of the system. With the continuous expansion of new energy grid-connected power generation, the demand for spinning reserve of the system has increased sharply, and the new energy power generation capacity is seriously insufficient. Under the background of intelligent power grid, the interaction between flexible and controllable loads and the power grid is enhanced, and the participation of controllable loads in dispatching helps to improve system reliability and economy. In order to ensure the safe and stable operation of the power system and promote wind power consumption, it is necessary to improve th...
