Abstract: This paper proposes a novel high-gain three-port power converter with fuel cell (FC), battery sources and stacked output for a hybrid electric vehicle (HEV) connected to a dc-microgrid. In the proposed power converter, the load power can be flexibly distributed between the input sources. Moreover, the charging or discharging of the battery storage device can be controlled effectively ...

Abstract: Interest in DC microgrids is rapidly increasing along with the improvement of DC power technology because of its advantages. To support the integration process of DC microgrids with the existing AC utility grids, the form of hybrid AC/DC microgrids is considered for higher power conversion efficiency, lower component cost and better power quality. In the system, AC and DC portions are...

DC microgrid has been gaining popularity as solution a more efficient and simpler power system especially for remote areas, where the main grid yet to be built. This paper proposes based on renewable energy sources that employs decentralized control without communication between one point another. It can deployed an individual isolated unit or form expandable through bus better reliability effi...

In recent times, DC microgrids (MGs) have received significant attention due to environmental concerns and the demand for clean energies. Energy storage systems (ESSs) photovoltaic (PV) are parts of MGs. This paper expands on modeling control non-isolated, non-inverting four-switch buck-boost (FSBB) synchronous converters, which interface with a wide range low-power electronic appliances. The p...

Inverter voltage control is an important task in the operation of a DC/AC microgrid system. To improve the inverter voltage control dynamics, traditional approaches attempt to measure and feedforward the load current, which, however, needs remote measurement with communications in a microgrid system with distributed loads. In this paper, a load current observer (LCO) based control strategy, whi...

A DC microgrid has many advantageous features, such as low power losses, zero reactive power, and a simple interface with renewable energy sources (RESs). bipolar is also highlighted due to its high-power quality, improved reliability, enhanced system efficiency. However, the high bus voltage fluctuation load unbalance between poles. Therefore, this paper analyzes that can occur in microgrid. A...

An intrinsically stable microgrid, operated by inverter-interfaced distributed energy resources (I-DERs) is introduced in this paper. The microgrid built upon a systematic design method, which adapted from the operation of synchronous machine (SM). proposed method analogizes dynamics dc-link I-DERs to rotor generators (SGs) and utilizes capacitor as storage. Thus, mechanism relaxes battery usag...

Hybrid DC microgrid clusters contain various types of converters such as BOOST, BUCK, and bidirectional DC/DC converters, making the control strategy complex difficult to achieve plug-and-play. The common master–slave hierarchical makes it accurate stable system control. This paper proposes an peer-to-peer method for hybrid cluster, working principle this is analyzed in detail. cluster consists...
