DC Microgrid Stability Analysis Considering Time Delay in the Distributed Control

Control of a DC Microgrid

A microgrid is a part of a distribution network embedding multiple distributed generation systems (mostly nonconventional renewable energy sources like photovoltaic panels, small wind turbines etc.) and storage systems with local loads, which can be disconnected from the upstream network under emergency conditions or as planned. The microgrid concept naturally arose to cope with the penetration...

A Distributed Control Architecture for Autonomous Operation of a Hybrid AC/DC Microgrid System

Hybrid AC/DC microgrids facilitate the procedure of DC power connection into the conventional AC power system by developing the distributed generations (DGs) technologies. The conversion processes between AC and DC electrical powers are more convenient by hybrid systems. In this paper, an energy management system (EMS) for a hybrid microgrid network is proposed due to the optimal utilization of...

Robust Time-Delay Control for the DC-DC Boost Converter

Modeling, Stability Analysis and Control of Microgrid

With the increase in the level of global warming, renewable energy based distributed generators (DGs) will increasingly play a dominant role in electricity production. Distributed generation based on solar energy (photovoltaic and solar thermal), wind, biomass, mini-hydro along with use of fuel cells and micro turbines will gain considerable momentum in the near future. A microgrid consists of ...

GLOBAL ROBUST STABILITY CRITERIA FOR T-S FUZZY SYSTEMS WITH DISTRIBUTED DELAYS AND TIME DELAY IN THE LEAKAGE TERM

The paper is concerned with robust stability criteria for Takagi- Sugeno (T-S) fuzzy systems with distributed delays and time delay in the leakage term. By exploiting a model transformation, the system is converted to one of the neutral delay system. Global robust stability result is proposed by a new Lyapunov-Krasovskii functional which takes into account the range of delay and by making use o...
