Abstract

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
