摘要

本文提出了一种新颖的两阶段随机节能降压（CVR）技术，即在电力和天然气一体化系统中使用混合整数二阶锥编程（MISOCP）模型来协调传统电压调节设备（有载分接开关（OLTC）和电容器组（CB））与光伏（PV）智能逆变器。在第一阶段，确定有载分接开关和电容器组的每小时日前最优设置，以及智能逆变器的基本无功功率设置。在考虑了预测负荷和光伏发电量的不确定性后，第二阶段确定了智能逆变器通过下垂控制进行的无功功率调整。此外，还提出了一种两步算法，以提高随机问题的求解速度。利用修改后的 IEEE 33 总线电力和 7 节点天然气测试系统、IEEE 123 总线电力和 20 节点天然气测试系统，以及加拿大萨斯卡通电力公司目前运行的 404 节点大型不平衡配电系统（与 20 节点天然气网络集成），对所提出的随机 CVR 技术进行了验证。

A Novel Stochastic Volt/VAR/Pressure Optimization-Based Conservation Voltage Reduction Technique in Integrated Electricity and Natural Gas Systems With PV Smart Inverters

This paper proposes a novel two-stage stochastic Conservation Voltage Reduction (CVR) technique in integrated electricity and natural gas systems, where the mixed-integer second-order cone programming (MISOCP) model is used to coordinate legacy voltage regulation devices (on-load tap changers (OLTCs) and capacitor banks (CBs)) with photovoltaics (PV) smart inverters. In the first stage, optimal hourly day-ahead settings of OLTCs and CBs, and the base reactive power settings of smart inverters are determined. After considering uncertainties in the forecasted load and PV power generation, reactive power adjustments from smart inverters through droop control are determined in the second stage. A two-step algorithm is also proposed to improve the solving speed of the stochastic problem. The proposed stochastic CVR technique is validated using the modified IEEE 33-bus electricity and 7-node natural gas test system, IEEE 123-bus electricity and 20-node natural gas test system, and a large unbalanced 404-node distribution system currently operated by Saskatoon Light and Power in Saskatoon, Canada, integrated with a 20-node natural gas network.
