Abstract

Electric spring (ES) is a new technology inspired by the idea of realization a system that is equivalent to mechanical springs in terms of functionality within power systems. Electric springs are comprised from a DC voltage source, an inverter and an LC filter at the grid side. It can be used effectively in power systems to perform many functions such as voltage regulation, reactive power compensation, demand management and energy storage. On the other hand, due to the semiconductor elements in ES structure, it causes distortion on voltage and current waveforms. However, various control approaches have been proposed in the literature in order to prevent the aforementioned distortions. In this study, three different ESs has been modeled with the inverter topologies chosen from the frequently preferred once used in applications, namely Half-Bridge, Full-Bridge, and Neutral Point Clamped Multi-Level Inverter (NPC-MLI). The disruptive effects of electric springs with different inverter topologies on the grid and their performance in harmonic elimination have been examined through the results obtained from simulations realized in MATLAB/Simulink®.

Özet

Elektrikli yay (ES), güç sistemlerinde işlevsellik açısından mekanik yaylara eşdeğer bir sistem gerçekleştirme fikrinden esinlenilerek geliştirilmiş yeni bir teknolojidir. Elektrikli yaylar bir DC gerilim kaynağından, bir inverterden ve şebeke tarafında bir LC filtreden oluşur. Güç sistemlerinde voltaj regülasyonu, reaktif güç kompanzasyonu, talep yönetimi ve enerji depolama gibi birçok işlevi yerine getirmek için etkin bir şekilde kullanılabilir. Öte yandan ES yapısındaki yarı iletken elemanlar nedeniyle gerilim ve akım dalga şekillerinde bozulmalara neden olur. Ancak söz konusu bozulmaların önüne geçebilmek için literatürde çeşitli kontrol yaklaşımları önerilmiştir. Bu çalışmada, uygulamalarda sıklıkla tercih edilen evirici topolojileri ile Yarım-Köprü, Tam- Köprü ve Nötr Nokta Kenetlemeli Çok-Seviyeli İnverter (NPC-MLI) olmak üzere üç farklı ES modellenmiştir. MATLAB/Simulink® programında gerçekleştirilen simülasyonlardan elde edilen sonuçlarla, farklı evirici topolojilerine sahip elektrik yaylarının şebeke üzerindeki bozucu etkileri ve harmonik gidermedeki performansları incelenmiştir.
