分时电价引导电解铝负荷参与百色区域电网调峰研究

Research on time-of-use pricing to guide electrolytic aluminum load to participate in the peak regulation of the Baise regional power grid

随着并网风电装机容量越来越大,现有的调度模式难以应对风电出力的随机性,为提高区域电网调峰和消纳风电的能力,提出利用分时电价引导电解铝负荷参与火力发电机组调峰的联合优化调度模型,模型以系统总的发电成本最小为目标,以区域电网运行数据为算例进行仿真验证,结果表明所提模型能够提高系统运行经济性和风电消纳能力。

With the increasing installed capacity of grid-connected wind power,the existing scheduling model struggles to cope with the randomness of wind power output.To improve the ability of the regional power grid to regulate and consume wind power,a joint optimal scheduling model that adopts time-of-use pricing is proposed to guide electrolytic aluminum load to participate in the peak regulation of thermal power generating units.This model aims to minimize the total generation cost of the system and uses regional power grid operating data as an example for simulation verification.The results show that the proposed model can improve the economic operation of the system and wind power consumption capacity.
