Abstract

Assessment of distributed generation (DG) is a complicated task and it is a primary importance step in designing and planning of DG installation in distribution systems. The installation of DG units at non-appropriate location and sizing can result in an increasing in power losses and violations of system constraints. In this paper, a new DG assessment tool is developed for studying and evaluating DG installations in practical distribution systems. The assessment tool is developed by writing DIgSILENT Programming Language (DPL) script in DIgSILENT PowerFactory software. The tool is used for evaluating initial grid connection of DG, considering multi-system constraints-i.e. types of DG units, location, sizing, system loading, reverse power, voltage regulation, step voltage change, short circuit level, and energy losses. Two practical distribution systems including 9-bus system and 410-bus system from Provincial Electricity Authority (PEA) of Thailand are used as case studies. Test results show that the proposed assessment tool which relies on PEA regulation of DG connection can be used to evaluate the specified DG installation.

考虑多系统约束的分布式发电初始并网评估工具的开发

分布式发电系统的评估是一项复杂的任务，是分布式发电系统设计和规划的重要环节。DG装置安装在不合适的位置和尺寸可能会导致功率损耗增加，并违反系统约束。本文开发了一种新的DG评估工具，用于研究和评估实际配电系统中的DG安装。该评估工具是在DIgSILENT PowerFactory软件中编写DIgSILENT编程语言(DPL)脚本开发的。该工具用于评估DG的初始并网，考虑了多系统约束，即。DG单元的类型、位置、尺寸、系统负载、反向功率、电压调节、阶跃电压变化、短路电平和能量损失。以泰国省电力局(PEA)的9总线系统和410总线系统两种实际配电系统为例进行了研究。试验结果表明，所提出的评估工具依赖于DG连接的PEA调节，可用于对指定DG安装进行评估。
