考虑电制氢辅助的配电网两阶段电压优化控制方法OA

The large-scale application of renewable energy in the distribution network poses a challenge to the voltage stability of the distribution network.This article proposes a two-stage voltage optimization control method considering the assistance of electric hydrogen production equipment.In the recent optimization phase,a global voltage regulation strategy was developed using an optimization model that includes dynamic constraints on hydrogen production equipment,with the goal of minimizing distribution network operating losses and hydrogen production costs.During the real-time control phase within the day,a bounded adaptive event triggered control method is adopted to dynamically adjust the triggering frequency of control instructions,in order to solve the voltage deviation problem caused by short-term power fluctuations with a lower response frequency of the hydrogen production equipment.Simulation examples show that the proposed method can reduce the voltage deviation amplitude of the distribution network by more than 10.24%,and the cost of voltage regulation can be reduced by more than 4.89%,demonstrating high voltage stability and good operational economy.
