Autonomous Operation of Hybrid AC-DC Microgrids
2010 IEEE International Conference on Sustainable Energy Technologies (ICSET), 2010This paper investigates on the active power sharing of an autonomous hybrid microgrid. Unlike existing microgrids which are purely ac, the hybrid microgrid studied here comprises a dc and an ac sub-grid, interconnected by a power electronic interface. To avoid complexity and save cost, the power interface should preferably be a simple traditional six ...

Hybrid AC/DC Microgrid for Residential Applications
2019 IEEE Third International Conference on DC Microgrids (ICDCM), 2019In this paper, we present the architecture and feasibility analysis of a hybrid AC/DC microgrid for residential applications. Although AC is ruling the building distribution architecture for years, however now DC is also appearing as a strong contestant due to a) large penetration of solar PV in residential power networks, b) decreasing prices of ...

Hybrid VSI Compensator for AC/DC Microgrid
2019 IEEE Region 10 Symposium (TENSYMP), 2019Microgrids are frequently subjected to power quality issues due to intermittency of renewable resources and nonlinear power electronic components connected in the system. These issues are rectified with the help of different categories of compensators such as dynamic voltage restorer, active filter, notch filter, static VAR compensators etc ...

Power flow analysis of AC/DC hybrid microgrids
2016 IEEE Electrical Power and Energy Conference (EPEC), 2016The future smart grid can have an AC/DC hybrid structure that enables the integration of AC/DC energy supply and demand, thus permitting the formation of AC/DC hybrid microgrids (HMGs). The AC/DC HMG is a promising concept that provides the envisioned smart grid with the plug-and-play feature. Nevertheless, understanding such hybrid systems, especially

Research and Simulation of Hybrid AC/DC Microgrid
2020 4th International Conference on HVDC (HVDC), 2020This paper mainly discusses the structure and control strategy of hybrid AC/DC microgrid. The AC/DC hybrid microgrid under consideration consists of photovoltaic (PV) panel, battery, DC load, AC load, induction motor and several converters. Using maximum power point tracking (MPPT) technology to optimize the output power of PV, the battery and ...

Steady-state analysis for hybrid AC/DC microgrids
2016 IEEE International Symposium on Circuits and Systems (ISCAS), 2016This paper demonstrates the generic models of different hybrid ac/dc microgrids components. The operational philosophy is oriented towards decentralized schemes while considering the absence of a single slack bus in the entire system. Instead, the DG units operate based on droop characteristics, thereby forming a multi-slack distribution system, and ...

Inexact power sharing in AC/DC hybrid microgrids
2016 IEEE Canadian Conference on Electrical and Computer Engineering (CCECE), 2016The AC/DC hybrid topology for the future smart grid is a promising configuration that allows integrating the energy resources and modern loads of AC and DC type. Understanding the AC/DC hybrid microgrids (HMGs) operating in islanding mode and its operational philosophy will pave the road towards the future smart grid with a plug-and-play feature.

Flexible Reliability Modeling in Hybrid AC-DC Microgrid
2013In this paper, a new concept of serving flexible reliability (FR) is introduced in distribution network level. FR is defined as the ability of a grid to continue servicing the high priority customers in contingency states. Customers’ priority is recognized based on their required value of service reliability.
