本文介绍了一种考虑光伏发电高渗透率的不平衡配电网络中集成电压/无功控制和保护电压降低（CVR）的新方法。使用平衡优化器 (EO) 算法求解基于混合整数非线性规划 (MINLP) 的 Volt/Var-CVR 问题。该方法协调智能光伏逆变器与电压调节设备（包括电压调节器（VR）和有载分接开关（OLTC））的使用。本研究的目的是通过在 IEEE 34 总线案例研究系统中实施智能光伏逆变器的 Volt/Var 控制模式，提高节能效果，最大限度地减少母线电压偏差，并减少遗留设备的运行。所提出的模型使用 COM 接口在 OpenDSS 和 MATLAB 程序之间进行交互，以找到 Volt/Var-CVR 问题的最优解。仿真结果验证了该方法的有效性，并表明在节能和功率损耗减少方面有显着的提高。
This paper introduces a new method for integrated Volt/Var control and Conservation Voltage Reduction (CVR) in unbalanced power distribution networks considering high penetration of PV generation. The mixed integer nonlinear programming (MINLP) based Volt/Var-CVR problem is solved using Equilibrium Optimizer (EO) algorithm. The method coordinates the use of smart PV inverters along with voltage regulating equipment including voltage regulators (VRs) and on-load tap changers (OLTCs). The objective of the study is to improve energy conservation and minimize busses voltage deviations and reduce the legacy device operations through implementing the Volt/Var control mode of smart PV inverters in the IEEE 34-bus case study system. The proposed model uses COM interface to make an interaction between OpenDSS and MATLAB programs to find the optimum solution of the Volt/Var-CVR problem. Simulation results authenticate the efficacy of the proposed method and demonstrate a considerable increase in the energy saving and power loss reduction.
