摘要

【目的】 针对传统分布式光伏承载力测算方法未统筹考虑输电网新能源消纳能力与配电网设备运行安全的问题,提出了一种考虑主配协同的分布式光伏承载力区间构建与最优求解方法。【方法】 首先,在输电网层面,考虑不同的省域新能源利用率水平和储能配置比例,依托生产模拟时序仿真构建分布式光伏承载力区间。然后,在配电网层面,以配电网投资经济性最优为目标,计及输配电网潮流、电能质量、储能充放电约束等,提出了一种分布式光伏承载力最优求解与区间校核方法。最后,选取我国不同区域省份进行算例分析。【结果】 结果表明,分布式光伏承载力区间可以与分布式光伏承载力最优解相互约束,兼顾满足输电网新能源消纳利用需求和输配电网可靠运行需求。【结论】 所提方法将分布式光伏纳入省域供需平衡计算,统筹考虑全量电源消纳空间对承载力计算的影响,科学评估电网可接入裕度,为引导分布式光伏合理布局提供了重要参考。

Abstract

[Objectice] In view of the problem that the traditional calculation method for distributed photovoltaic (PV) capacity cannot comprehensively consider the energy absorption capacity of the transmission network and the operational safety of network equipment, this paper proposes a method for constructing and optimally solving the distributed PV capacity interval considering the coordination between the transmission and distribution networks.[Methods] Firstly, at the transmission network level, considering different provincial new energy utilization rates and energy storage configuration ratios, the distributed PV capacity interval is constructed based on time-series simulation of production simulation.Secondly, at the distribution network level, with the goal of optimizing the investment economy of the distribution network, a method for optimally solving the distributed PV capacity and checking the interval is proposed, taking into account the power flow of transmission and distribution networks, power quality, and energy storage charging and discharging constraints.Finally, case studies are conducted in provinces of different regions in China. [Results] The results show that the distributed PV capacity interval and the optimal solution of distributed PV capacity can constrain each other, which can meet both the new energy absorption demand of the transmission network and the reliable operation demand of the transmission and distribution networks. [Conclusions] The proposed method incorporates distributed PV into the provincial supply-demand calculation, considers the impact of the absorption space of all power sources on capacity calculation, scientifically evaluates the accessible margin of the power grid, and provides an important reference for guiding the rational layout of distributed PV.
