in this paper a comprehensive approach is presented to improve power swings damping based on direct lyapunov method. the approach combines superconducting magnetic energy storage (smes) system with static synchronous compensator (statcom). considering the energy absorption/injection ability of smes, in transient states the combination exchanges both active and reactive powers with power system....
Using the FACTS controllers, such as static synchronous compensator (STATCOM), as it provides continuous reactive power, in the grid including wind turbine (WT) equipped with doubly fed induction generator, for improving voltage profile (under normal circumstances) and providing a transition ability from inductor generator transition state has been proposed. In this paper, in order to contr...
This paper focuses on improving the active and reactive power control of Wind Energy Conversion System (WECS) by employing the Battery Energy Storage System (BESS) and controlling the frequency and voltage regulation instantaneously. The proposed power control scheme is composed of two control loops so that they are implemented and designed for active power control and controlling the reactive ...
این پایان نامه در پنج فصل به شرح زیر تدوین گردیده است که در فصل اول به مقدمه ای در خصوص تعاریف مختلف توان راکتیو در محیطهای غیر سینوسی و همچنین روشهای اندازه گیری توان راکتیو برای رسیدن به بهترین حالت جبرانسازی توان راکتیو می پر دازیم در این بخش به منظور آشنایی بیشتر با موضوع، تحقیقات کتابخانه ای در موضوعات مورد بحث شامل سابقه تاریخی و کارهای انجام شده قبلی این زمینه به طور مختصر توضیح داده شده...
Optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. The distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...
Abstract: When several parallel inverters are in islands operating mode, the droop control scheme is usually used to control the inverters. The droop control method enables the inverters of a Micro-Grid to control the voltage and frequency of the network in a decentralized regulation behavior. The drop control method also enables the inverters to share the required active and reactive powers of...
