分布式光伏的大规模接入引起配电网电压越限问题。光伏作为新型调压主体,其自主性及多主体交互耦合增加了配电网调压的难度。因此,文中提出面向光伏用户群的多主体分级电压调控方法。首先,根据光伏的调压容量与电压支撑度建立分级模型。然后,在分级基础上利用主从博弈模型研究配电网调压过程中多主体之间的交互耦合特性:配电网运营商作为主侧,在保证电网安全稳定运行下分级设定调压补偿电价;光伏用户作为从侧,跟随调压补偿电价以调压收益最大为目标来优化无功调节策略。最后,通过仿真分析证明了所提方法能够有效解决电压越限问题并提高光伏用户收益。
Large-scale access of distributed photovoltaic causes the problem of voltage violation in the distribution network. As a new type of agent for voltage regulation
the autonomy and multi-agent interaction coupling of photovoltaic increase the difficulty of the voltage regulation in distribution networks. Therefore
a multi-agent classified voltage regulation method for photovoltaic user group is proposed. Firstly
the classified model is established according to the voltage regulation capacity and voltage support index of photovoltaic. Then
on the basis of classification
the interaction and coupling characteristics of multiple agents in the process of voltage regulation in distribution networks are studied using the Stackelberg game model. Distribution network operators as the leader
determine the compensated price of voltage regulation while ensuring the safe and stable operation of the power grid. Photovoltaic users
as the follower
optimize the reactive power regulation strategy with the goal of maximizing voltage regulation benefit based on the voltage regulation price. Finally
it is proved that the proposed method can effectively solve the problem of voltage violation and improve the benefits of photovoltaic users by the simulation analysis.
