A Repetitive Control- based Approach for Power Sharing among Boost Converters in DC Microgrids
In this paper a repetitive control (RC) approach to improve current sharing between parallel-connected boost converters in DC microgrids is presented. The impact of changes in line impedance on current sharing is investigated. A repetitive controller is designed and connected in series with current controller of the boost converters to control the switching signals such that by regulating of th...
متن کاملRobust Distributed Control of DC Microgrids with Time-Varying Power Sharing
This paper addresses the problem of output voltage regulation for multiple DC/DC converters connected to a microgrid, and prescribes a scheme for sharing power among different sources. This architecture is structured in such a way that it admits quantifiable analysis of the closed-loop performance of the network of converters; the analysis simplifies to studying closed-loop performance of an eq...
متن کاملStability analysis of DC microgrids with constant power load under distributed control methods
Constant power loads (CPLs) often cause instability due to its negative impedance characteristics. In this study, the stability of a DC microgrid with CPLs under a distributed control that aims at current sharing and voltage recovery is analyzed. The effect of the negative impedance on the behavior of distributed controller are investigated. The small-signal model is established to predict the ...
متن کاملLoad demand Sharing using multiple distributed generation units for the operation of microgrids to realize satisfied power sharing
The important task for the operation of autonomous micro grids, is to share the load demand using multiple distributed generation units. In this paper to realize satisfied power sharing without the communication between DG units, the voltage droop control and its different variations have been proposed. Generally, in a lowvoltage micro grids, due to the effects of feeder impedance, the droop co...
متن کاملDynamic Optimisation for Power Dispatch in Microgrids
The increasing growth of non-dispatchable renewable energy sources (RES) such as solar and wind and the upcoming plug-in electric vehicles (PEVs) makes the secure power dispatch a challenging optimisation. In this paper, a coordinated power dispatch strategy in microgrids with a battery management system is proposed. The power dispatch strategy dynamically fits the power production to the power...
