基于弃风利用的塔筒电梯供电模式研究

Research on the power supply mode of tower elevator based on the abandoning wind

目前弃风现象日益严重,从对弃风部分消纳的要求出发,提出运用弃风电量为塔筒电梯供电并在弃风不足时使用储能系统作为塔筒电梯的补充电源的供电模式。以配置储能系统经济性最优为目标,建立了塔筒电梯储能系统模型,使用遗传算法(GS)优化储能配置。采用新疆某风电场的实际统计数据计算风电场弃风电量和塔筒电梯使用功率。通过算例计算得出储能电量和充放电功率,并优化储能系统的参数使储能系统运行成本最低,结果表明,基于弃风利用的塔筒电梯需要配置的供电模式方案是可行的。

At present, the phenomenon of abandonment of wind is becoming more and more serious. Based on the requirement for partial elimination of the wind,a power supply mode is proposed that uses power from abandoning the wind to supply power to the tower elevator and uses the energy storage system as a supplemental power supply to the tower elevator when the wind is insufficient. In order to optimize the economical efficiency of the energy storage system, a tower elevator energy storage system model was established and a genetic algorithm（GS） was used to optimize the energy storage configuration. The actual statistical data of a certain wind farm in Xinjiang is used to calculate the wind power of wind farms and the power of tower elevators.Calculating the required energy storage capacity and charging and discharging power through calculation examples,and optimizing the parameters of the energy storage system to make the operation cost of the energy storage system the lowest, the results indicate the feasibility of the power supply scheme of the tower elevator based on the abandoned wind utilization.
