Abstract

The invention belongs to the technical field of comprehensive energy system optimization operation, and particularly relates to a regional comprehensive energy system flexibility optimization configuration method for wind curtailment consumption. The method comprises the following steps: (1) determining the structure of an energy hub, including energy transmission equipment, energy conversion equipment and energy storage equipment, and setting a flexibility option SW1; (2) determining upper and lower limits of a control variable and an initial value of the control variable according to the typical daily load and the wind power data; (3) setting a target function option SW2, and establishing an optimal configuration model taking the minimum operation cost, wind curtailment punishment cost and electricity purchasing and selling cost as a target according to the initial value of the control variable obtained in the step (2) and the upper limit constraint; and (4) under the constraint condition of each equipment, solving an objective function of the optimal configuration model through a nonlinear programming solving method to obtain an optimal operation scheme of the regional comprehensive energy system. The wind curtailment consumption capacity is improved, the energy use efficiency is improved, and the operation cost of a regional comprehensive energy system is reduced.

Description

technical field [0001] The invention belongs to the technical field of optimized operation of an integrated energy system, and in particular relates to a flexible optimal configuration method of a regional integrated energy system oriented to curtailment and accommodation. Background technique [0002] Large-scale access to renewable energy has brought new problems and challenges to the flexible, reliable, and economical operation of the power system. Renewable energy will affect the safe and stable operation of the power system to a certain extent, but renewable energy with strong controllability can be converted into flexible resources under certain circumstances, which will have a positive effect on the flexibility of the power system. Under the condition of ensuring the stable output of renewable energy, grid-connected renewable energy with appropriate capacity can reduce the output of traditional units, improve the operation status of the power system, and thus improve ...
