Abstract

This paper presents a headroom-based optimization for the placement of distributed generation (DG) in a distribution substation. The penetration limits of DGs into the existing distribution substations are often expressed as a function of the feeder’s hosting capacity (headroom). Therefore, it is important to estimate the reliability of the network's operation as well as that of the limits imposed by the power quality standards by evaluating of the hosting capacity (headroom) of the existing distribution feeder substation. This study aims at developing a novel algorithm for positioning a bus with permissible headroom capacity for DG positioning without causing voltage violations but maximizing the active power supply. Since DG increases short-circuit faults, the algorithm is useful for utility companies to select feeder substations that have permissible headroom capacity for DG installation and thus, contributing to reducing high DG penetration in the network. The modeling and optimization were carried out the Power System Software for Engineers (PSS/E) environment using the IEEE 14-bus test system. The results obtained from the case study show that only two (2) feeder substations out of fourteen (14) have the permissible headroom capacity for DG connections.

基于净空空间的配电变电所分布式发电布局优化

本文提出了一种基于净空空间的配电变电所分布式发电(DG)布局优化方法。dg对现有配电变电站的渗透极限通常表示为馈线承载能力(净空)的函数。因此，通过评估现有配电支线变电站的承载能力(净空)来评估电网运行的可靠性以及电能质量标准所施加的限制是很重要的。本研究旨在开发一种新的算法，以定位具有允许的净空容量的母线用于DG定位，而不会造成电压违规，但最大限度地提高有功功率。由于DG增加了短路故障，因此该算法对公用事业公司选择具有允许的DG安装净空容量的馈线变电站非常有用，从而有助于减少DG在网络中的高渗透率。采用IEEE 14总线测试系统，在电力系统工程师软件(PSS/E)环境下进行建模和优化。从案例研究中获得的结果表明，十四(14)中只有两(2)个馈线变电站具有DG连接的允许净空容量。

期刊介绍： Engineering Review is an international journal designed to foster the exchange of ideas and transfer of knowledge between scientists and engineers involved in various engineering sciences that deal with investigations related to design, materials, technology, maintenance and manufacturing processes. It is not limited to the specific details of science and engineering but is instead devoted to a very wide range of subfields in the engineering sciences. It provides an appropriate resort for publishing the papers covering prior applications – based on the research topics comprising the entire engineering spectrum. Topics of particular interest thus include: mechanical engineering, naval architecture and marine engineering, fundamental engineering sciences, electrical engineering, computer sciences and civil engineering. Manuscripts addressing other issues may also be considered if they relate to engineering oriented subjects. The contributions, which may be analytical, numerical or experimental, should be of significance to the progress of mentioned topics. Papers that are merely illustrations of established principles or procedures generally will not be accepted. Occasionally, the magazine is ready to publish high-quality-selected papers from the conference after being renovated, expanded and written in accordance with the rules of the magazine. The high standard of excellence for any of published papers will be ensured by peer-review procedure. The journal takes into consideration only original scientific papers.
