Comparative study of unipolar and bipolar industrial DC microgrids through linear power flow

, 2023
Unipolar and bipolar voltage buses are used in DC microgrids. Though each type has its advantages, the choice between the two of them is not trivial. This paper uses an iterative linear load flow to compare the performance of two DC microgrids.

Current Control of Three‐Phase Inverter Using a Data‐Driven Model‐Free Adaptive Controller for Power Quality Improvement

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
This paper introduces a data‐driven model‐free adaptive controller (DDMFAC) as a powerful, practical, and suitable alternative to improve the limitations, challenges, and inherent problems of conventional model–based methods. The proposed method, using input–output data processing independent of the mathematical and systematic model, acts as an ...

Concept Proof of Voltage Suppression across IGBT Application for Fuse‐Current‐Limiting Hybrid DCCBs

IEEJ Transactions on Electrical and Electronic Engineering, Volume 20, Issue 12, Page 1973-1981, December 2025.
Abstract DC power systems require reliable and cost‐effective DC circuit breakers (DCCBs). In a previous study, we introduced a hybrid DCCB featuring a current‐limiting fuse, insulated gate bipolar transistor (IGBT), and a varistor connected in parallel.

Grid Integration of Single‐Phase Inverters Using a Robust PLL‐Less Control Strategy for Renewable Energy Applications

Energy Science &Engineering, Volume 13, Issue 9, Page 4539-4552, September 2025.
ABSTRACT In this paper, a PLL‐less control technique for single‐phase grid‐connected voltage source converter (VSC) system is proposed that overcomes shortcomings in traditional PLL‐based and existing PLL‐less techniques. The proposed method avoids the use of a PLL and thus significantly decreases the computational complexity of the system as well as ...

Performance analysis of DC microgrids with output resistance shaping in presence of constant power loads

Energy Conversion and Economics, Volume 6, Issue 3, Page 196-212, June 2025.
Abstract Constant power loads (CPLs) introduce negative impedance in direct current microgrids (DCMGs), which is a major challenge. This negative impedance can significantly reduce the overall damping of the system, making it less stable and harder to control. To address this issue, output virtual resistance (VR) shaping is commonly employed to enhance
