Abstract

ABSTRACT Voltage control and power loss minimization are some of the crucial issues in distribution system energy management. Finding the best strategy for Voltage control and power loss reduction is a critical task for the distribution network operator (DNO). The main contributions of the proposed work are (i) determination of size and location of the Distribution Static Synchronous Compensator (DSTATCOM) with (OLTC). (ii) to minimize the power loss and Voltage deviation with the Volt/var control strategy. (iii) To obtain the impact of single and multiple D-STATCOM units with and without OLTC. The proposed method is tested on two test systems: (i) IEEE-69 RDS and (ii) IEEE-25 bus three-phase unbalanced system. The benefits of the proposed results are addressed in the reduction of power loss, enhancement of the Voltage profile, and the annual cost of saving for the DNO. The results are tabulated, verified, and compared with other methods. The power loss is reduced to 39.25%, 38.04% for 69 bus and 25 bus test systems. The minimum Voltage profile is enhanced from 0.90918 pu to 0.9619 pu for 69 bus RDS and from 0.922559 pu to 0.9747 pu for 25 bus three-phase system.

D-STATCOM和OLTC集成电压/无功控制在配电系统中对减损和电压控制的影响

电压控制和功率损耗最小化是配电系统能量管理中的一些关键问题。寻找电压控制和功率损耗降低的最佳策略是配电网运营商（DNO）的一项关键任务。所提出的工作的主要贡献是（i）确定带有（OLTC）的配电静态同步补偿器（DSTATCOM）的尺寸和位置。（ii）利用Volt/var控制策略来最小化功率损耗和电压偏差。（iii）获得带有和不带有OLTC的单个和多个D-STATCOM单元的影响。该方法在两个测试系统上进行了测试：（i）IEEE-69 RDS和（ii）IEEE-25总线三相不平衡系统。所提出的结果在减少功率损耗、增强电压分布和DNO的年度节约成本方面得到了解决。将结果制成表格，进行验证，并与其他方法进行比较。69总线和25总线测试系统的功率损耗分别降低到39.25%和38.04%。69总线RDS的最小电压分布从0.90918 pu提高到0.9619 pu，25总线三相系统的最小电压曲线从0.922559 pu提高到0.9 747 pu。
