摘要/Abstract

摘要： 针对含高比例新能源接入的配电网普遍存在低电压、过电压、不平衡电压、线路过载、线损过高等问题,提出一种面向边端协同的有源配电网灵活储能优化调控方法。首先,基于配电物联网的端边云理念技术,构建以通信服务为依托的终端设备层和边缘计算服务层协同运行架构,厘清配电网终端多源设备与智能融合终端平台之间的调度信息交互机理。其次,考虑电池储能可以根据电网需求自适应调整电池并网容量,建立模块化串联型电池储能的数学模型。在此基础上,计及电池储能的充放电成本、运行维护成本及调压成本,提出有源配电网灵活储能有功-无功协同优化调控方法。最后,以IEEE 33节点系统为仿真算例,验证了所提方法对提升配电网运行经济性和电压质量的有效性。

Abstract: Aiming at the problems commonly existing in distribution networks with high-proportion new energy integration, such as low voltage, over-voltage, unbalanced voltage, line overload and excessive line loss, a flexible energy storage optimized control method for active distribution networks oriented to edge-terminal coordination is proposed. Firstly, based on the terminal-edge-cloud concept technology of the distribution internet of things, a coordinated operation architecture of the terminal equipment layer and the edge computing service layer relying on communication services is constructed, and the scheduling information interaction mechanism between the multi-source devices at the distribution network terminal and the intelligent integrated terminal platform is clarified. Secondly, considering that battery energy storage can adaptively adjust the battery grid-connected capacity according to the grid demand, a mathematical model of modular series battery energy storage is established. On this basis, taking into account the charging and discharging costs, operation and maintenance costs and voltage regulation costs of battery energy storage, a coordinated optimized control method for active and reactive power of flexible energy storage in active distribution networks is proposed. Finally, case studies on the IEEE 33-node system verify the effectiveness of the proposed method in enhancing the operational economy and voltage quality of distribution networks.

Key words: active distribution network, flexible energy storage, edge-terminal coordination, voltage quality, optimized control
