摘要
由于交直流混合配电网具有灵活性和可控性的特点,得到广泛的应用,同时电动汽车和空调的规模化接入使得配电网尖峰负荷持续增大。基于此,提出基于两阶段鲁棒博弈的交直流混合配电网调峰运行管控模型。首先,考虑电网公司与电动汽车代理商、储能运营商之间的主从博弈,构建运营收益最大和峰谷差最小的电网公司(领导者)多目标两阶段鲁棒优化模型,以及储能运营商和电动汽车代理商(跟随者)收益优化模型,并证明该主从博弈均衡的存在性与唯一性;其次,将跟随者模型采用KKT条件等效为领导者模型中均衡约束,双层主从博弈模型等效为单层两阶段鲁棒优化模型,并采用CCG算法求解;最后,通过仿真计算,结果表明所提的调峰管控策略可以实现交直流配电网的削峰填谷和多主体间的利益均衡。
AC/DC hybrid distribution network has been widely adopted for its high flexibility and control ability.In addition,the large-scale access of electric vehicles and air conditioners can increase the peak load of distribution network.This paper proposed a load peak operation control model for AC/DC hybrid distribution network based on two-stage robust game.Firstly,a master-slave game model among grid companies,the electric vehicle agents and energy storage operators was built.Then,a multi-objective two-stage robust optimization model for grid companies(leaders)with maximum profit and minimum peak-valley difference was established.Meanwhile,two profit optimization models for energy storage operators and electric vehicle agents(followers)were built respectively.The existence and uniqueness of the master-slave game equilibrium was proved.Secondly,the follower model was equivalent to the equilibrium constraint in the leader model by KKT condition.So,the two-layer master-slave game model was equivalent to a single-layer two-stage robust optimization model,which was solved by CCG algorithm.Finally,the simulation results show that load peak operation control strategy can achieve load peak shaving for AC/DC hybrid distribution network and interest balance among multi-stakeholders.
