摘要/Abstract

摘要： 随着碳中和目标的明确，通过技术手段降低社会用能成本对能源低碳转型有着重要意义。基于此提出一种主动配电网降压节能（conservation voltage reduction, CVR）运行方法。采用负荷指数模型，通过有载调压变压器（on-load tap changer，OLTC）调节实现降压节能运行，配以网络重构、分布式电源（distributed generations，DGs）调节等主动管理策略保证降压节能运行的同时满足供电电能质量要求，实现一段时间内配电系统总能耗最小。通过IEEE 33节点配电网算例分析，验证了所提方法的有效性和合理性。

Abstract: With the goal of carbon neutralization clear, reducing the social energy cost through technical means is of great significance for energy low-carbon transformation. Based on this background, this paper proposes a Conservation Voltage Reduction (CVR) operation method for medium-voltage power distribution system. CVR refers to operating under a lower voltage range on the premise of satisfying the supply voltage deviation, so as to achieve the purpose of energy saving and consumption reduction. The method proposed in this paper adopts the load exponential model and realizes the voltage reduction and energy saving operation through the adjustment of On-Load Tap Changer (OLTC). Coupled with the reactive compensation of the capacitor bank, network reconstruction, and distributed generations (DGs), the regulation guarantees that the voltage reduction operation meets the power quality requirements of the power supply to achieve the minimum total energy consumption of the distribution system within a period of time. Through the analysis of IEEE 33 node distribution system examples, the effectiveness and rationality of the proposed method are verified.

Key words: active distribution network, distributed generations, conservation voltage reduction, optimal operation
