“…Pokharel mainly solves the problems of intermittent and slow dynamic response in microgrids, and proposes a vertical control strategy based on DC bus signal. The effectiveness of the method has been verified through simulation [2]. Singh proposed a new power management strategy for power sharing between batteries and supercapacitors in energy storage systems, which is used to improve the efficiency of microgrid operation and has reference significance for the control of DC microgrids.…”

<p>As the future direction of power development, microgrids are particularly important for rational and efficient energy management. This article establishes an optimization model with multiple uncertainties as parameters for the microgrid energy system, with the objective function of minimizing operating costs. Then, an improved harmony algorithm was used to solve for the optimal solution of the model parameters. Finally, a microgrid system consisting of wind and thermal power units established in a certain area of Hebei Province was used for solution analysis. After experimental verification, the proposed method in this paper achieved significant improvements in both operational cost reduction and microgrid efficiency.</p> <p> </p>

“…Among these, droop control adjusts the relationship between the DC voltage and current through negative slope characteristics to realize the real-time control of the system power balance, which is a differential regulation. It has been widely used in DC distribution networks [5][6][7]. However, the line impedance impacts the droop coefficient, which will affect the output voltage of each converter station and the reasonable sharing of the system's load current among them [8].…”

DC distribution networks are low-inertia systems with a range of uncertainties and disturbances. The traditional droop control widely used in DC distribution networks has a contradiction between the accurate power sharing of power units and voltage deviation due to the presence of line impedance. To overcome this contradiction and enhance the immunity and tracking performance of voltage-source converter (VSC) current inner loop PI control, this paper proposes a coordinated voltage-power control strategy based on an uncertainty and disturbance estimator (UDE) for DC distribution networks. Firstly, the improved droop control strategy based on the UDE is proposed, which not only avoids the influence of line impedance on the load current sharing, but also achieves voltage stabilization at the set value. Secondly, an improved VSC current inner loop controller based on the UDE is designed to improve the VSC’s tracking performance for the droop output reference value. The UDE control theory is applied to estimate and compensate for the uncertainties and disturbances of the VSC current inner loop control, in order to improve the tracking and immunity of the VSC current inner loop and enhance the DC voltage robustness. Finally, a three-terminal DC distribution network is taken as an example to verify the effectiveness of the proposed strategy.

“…Following is the suggested approach to charging for BESSs, i.e., steady current/consistent voltage (CC/CV) charging, the ordinary strategies go through mode exchanging utilizing a floating reference worth to control CV charging which doesn't ensure zero current when the battery is completely energized [12][13][14][15].…”

This paper describes the possibility of the application of a DC Microgrid with a. DC Microgrids open a passage for the incorporation of several smart grid-based energy, which is a proficient and cleaner method of environmentally friendly power age, which can be coordinated into the power dissemination organization. DC microgrid is a wise blend of brilliant networks and sustainable sources with an expansion in the productivity of energy. In this way, very little energy is squandered during circulation and transmission. It enjoys a few different benefits, which remember - a decrease in transmission misfortunes, improvement in influence quality and dependability, decrease in emanations and even it is cost-viability. The circuit for sun-oriented power accessibility detecting and changing to battery supply is finished on equipment. The plan of a DC microgrid from sun-oriented energy is finished in the main trademark is that it gives a likelihood to charge of far-off towns which are a long way from the range of the conventional grid.
