高比例户用光伏单相接入低压配电网会导致电压越上限、三相不平衡加剧、网络损耗增大,在用户侧配置储能装置可以有效改善上述问题。针对配电台区进行储能优化调度时低压用户和电网利益不一致的问题,提出了考虑高比例光伏配电台区多主体利益的分散储能多目标优化方法,以配电网和用户的综合满意度最大作为目标函数,以储能有功功率为优化变量,建立了考虑电网–用户利益均衡的储能分散调度模型。根据配电网网损、用户储能补偿成本、三相不平衡度构建电网满意度函数,根据用户用电成本、储能退化成本构建用户满意度函数,进而采用CPLEX中的分支定界法对模型求解。算例仿真结果表明,相对于只考虑电网利益或者用户利益,文中方法可以有效提高电网、用户的整体满意度,同时电压越限、三相不平衡问题得到极大改善。
The unbalanced connection of large-scale residential PVs integrated into distribution station area will result in issues such as voltage violation
increased three-phase imbalance and increased network losses. These issues can be effectively solved through the installation of energy storage devices on the user side. In this paper
we propose an optimal dispatching method of decentralized energy storage in distribution substations with a high proportion of PVs considering the equilibrium of benefits of multiple subjects
to address the inconsistency between the interests of low-voltage users and the power grid during the optimal dispatch of energy storage. A comprehensive satisfaction optimization model considering the balance of grid-user benefits is established by considering low-voltage three-phase four-wire network structure and energy storage degradation
taking the maximum sum of satisfaction of the distribution network and users as the objective function and the active power of energy storage as the control variable. The power grid satisfaction function is constructed according to the distribution network loss
user energy storage compensation cost
and three-phase imbalance. Similarly
the user satisfaction function is established based on user electricity cost and energy storage degradation cost. The CPLEX software is utilized to solve the comprehensive satisfaction optimization model. The simulation results of the 21-node distribution station area demonstrate that
compared to solely considering the interests of the power grid or the interests of users
the method proposed in this paper effectively strike a balance among the grid-user benefits
while significantly improving the voltage limit and three-phase imbalance issues.
