In this paper, the solvability of power-flow equation of DC microgrid with CPLs is analyzed, where a majority of distributed generations (DGs) are under MPPT control while other DGs are under droop
trategies for DC microgrids? In this paper, the performances of three voltage control strategies for DC microgrids are compared, including the proportion integration (PI) control, the fuzzy PI control and
To further this objective, this standard establishes, for each nominal system voltage, two ranges for service voltage and utilization voltage variations, designated as Range A and Range B, the limits of
There are numerous methods for locating the best solution for the problems of microgrid EM. There are, primarily, two distinct ways to flow power.
In this paper, both ICA and GA, as well as their hybrid application, are used to significantly enhance the voltage regulation in microgrids. The integration of optimization techniques
In DC microgrids, it is necessary to restrict voltage deviations of buses connecting to voltage-sensitive loads within admissible ranges to guarantee normal operations of the loads, but there are no rigorous
It can be seen in both the piecewise and proposed methods, the voltage deviation has been reduced to a desirable extent, but in the droop and SOC-based methods, the DC bus voltage
The choice of voltage is dependent on three factors: the electrical load, the distances involved, and national standards. Systems with higher loads over a distribution feeder are likely to use higher
Increasing the allowable voltage deviation of the DC microgrid can increase the power supply radius and power supply range. However, allowing too much voltage deviation will increase
Voltage variation over the course of a time, season, loading is something that the utilities and customer have to tolerate. However, it is possible to design a power system that should work seamlessly
