Bidirectional DC-DC Converter and Single-Phase Grid-Connected Inverter Design for Energy Management in V2G Topology

Abstract

As renewable energy resources dwindle and the world's population grows, the balance between energy supply and demand is being adversely affected. The rapid increase in the number of EVs causes power quality problems in existing conventional grids. Topologies such as V2G, G2V, and V2H are being studied in order to overcome these problems. In this study, a microgrid is designed for power flow in single-phase V2G topology. In this microgrid, there is one EV, one home, and one PV panel. The EV is charged by the PV panel during the daytime when it is in the parking lot. When there is a power quality problem in the microgrid, the V2G topology is activated and power flows from the EV battery to the grid. A single-phase grid-connected inverter and a bidirectional DC-DC converter were designed to operate this system. The simulations of the designed microgrid were performed in the MATLAB/Simulink program. According to the simulation results, installing this system in homes or workplaces with EVs, charging the EV battery with PV panel, and using the EV battery to eliminate power quality problems that may occur in the existing microgrid provides a solution for single-phase V2G topology.

V2G Topolojisinde Enerji Yönetimi için Çift Yönlü DC-DC Dönüştürücü ve Tek Fazlı Şebeke Bağlantılı Evirici Tasarımı

Abstract

Yenilenebilir enerji kaynaklarının azalması ve dünya nüfusunun artmasıyla birlikte enerji arz talep dengesi olumsuz etkilenmekte. EV sayısının hızla arması mevcut konvansiyonel şebekelerde güç kalitesi problemlerine neden olmaktadır. Bu problemlerin üstesinden gelebilmek için V2G, G2V ev V2H gibi topolojilerde çalışmalar yapılmaktadır. Bu çalışmada tek fazlı V2G topolojisinde güç akışı için bir mikro şebeke tasarlandı. Bu mikro şebeke içerisinde bir adet EV, bir adet ev ve bir adet PV panel bulunmaktadır. EV gündüzleri otoparkta iken PV panel ile şarj olmaktadır. Mikro şebekede güç kalitesinde bir problem olduğunda ise V2G topolojisi işletilerek EV bataryasından şebekeye güç akışı gerçekleştirilmektedir. Bu sistemin işletilebilmesi için bir adet tek faz şebeke bağlantılı evirici ve bir adet çift yönlü DC-DC dönüştürücü tasarımı gerçekleştirilmiştir. Tasarlanan mikro şebekenin simülasyonları MATLAB/Simulink programında yapılmıştır. Simülasyon sonuçlarına göre EV bulunan evlerde ya da iş yerlerinde bu sistem kurularak PV panel ile EV bataryasının şarj edilmesi ve EV bataryasının mevcut mikro şebekede oluşabilecek güç kalitesi problemlerinin giderilmesinde kullanılması tek fazlı V2G topolojisi için bir çözüm önerisi sunmaktadır.
