摘要(Abstract):

大量广义负荷接入配电网,使得用户侧负荷资源具备负荷和电源双重特性,建立一种新的弹性平衡是配电网规划研究的趋势。提出一种考虑广义负荷的配电网弹性电力电量平衡策略,以供电可靠性和供电设施容量为约束,以碳排放和弹性成本最小为目标,构建弹性负荷参与的弹性电力电量平衡模型,采用离散化隐枚举法和启发式算法进行模型求解。算例分析结果表明,弹性电力电量平衡策略的应用有利于节省电网投资、减少区域电网峰谷差,提高电网的弹性调节能力。
The large-scale access of generalized loads to distribution networks makes load sources on the user side a carrier of both load and power supply. It is a trend for distribution planning and research to build a new elastic balance. This paper proposes an elastic electric power and energy balance strategy for distribution networks considering generalized loads. Based on the constraints of power supply reliability and facility capacity,and with the goal of minimizing carbon emission and elastic cost,an elastic power and energy balance model with elastic load participation is established. Finally,the discrete implicit enumeration method and heuristic algorithm are used to solve the model. The calculation results show that the application of the elastic power and energy balance strategy is beneficial to saving the investment of the power network,reducing the peak-valley difference of local power grid,and improving the elastic adjustment ability of the regional power grid.
