A Novel Reconfiguration Mixed with Distributed Generation Planning via Considering Voltage Stability Margin
In recent years, in Iran and other countries the power systems are going to move toward creating a competition structure for selling and buying electrical energy. These changes and the numerous advantages of DGs have made more incentives to use these kinds of generators than before. Therefore, it is necessary to study all aspects of DGs, such as size selection and optimal placement and impact o...

چکیده رساله/پایان نامه : تاکنون روشهای متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روشها در شبکه توزیع به دلایلی همچون وجود انشعابهای متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تکفاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...
Estimating the Active Power Transfer Margin for Transient Voltage Stability
On-line security analysis is one of the important functions for modern power system control centers. It is well known that voltage magnitudes alone are poor indicators of voltage stability or security. Voltages can be near normal with generators, synchronous condensers, and SVCs near current limiting levels resulting in a possible voltage collapse. For on-line application, a pattern matching or...

متن کاملA multi-agent approach for decentralized voltage regulation in power distribution networks within distributed generators
Voltage regulation (VR) is a procedure to keep voltages in a distribution network (DN) within normal limits. Conventionally, a voltage regulator can read voltage levels from predefined measures, and regulate the voltages. However, due to lacking of a distributed generator’s (DG) information, the unexpected electricity from a DG will mislead readings on voltages levels, so as to disturb the VR i...
