“…In this paper, MPPT (maximum power point tracking) control was used for distributed generators such as wind turbines and PVs to achieve maximum power utilization. The constant voltage unit is aimed at stabilizing bus voltage [23]. For the energy storage unit, a droop control method is applied to the DC bus voltage [24].…”

In order to improve the stability of direct current (DC) microgrid with constant power loads, a novel virtual inductive approach is proposed in this paper. It is known that the negative impedance characteristic of constant power loads will lead to DC bus voltage fluctuation, which will be more serious when they integrate into the DC microgrid though a large transmission line inductive. For the convenience of analysis, a simplified circuit model of the system is obtained by modeling the distributed resources. Unlike the existing control strategies, the proposed control strategy constructs a negative inductance link, which helps to counteract the negative effects of the line inductive between the power source and the transmission line. Detailed performance comparison of the proposed control and virtual capacitance are implemented through MATLAB/simulink simulation. Moreover, the improved performance of the proposed control method has been further validated with several detailed studies. The results demonstrate the feasibility and superiority of the proposed strategy.

“…Despite the practical difficulties that exist for the development of networks in DC (lack of standardization, for example, with an impact on a resource market poorer than that of AC [16]) these structures have aroused considerable interest in the scientific community, especially as an alternative for the energy supply from renewable sources in isolated areas [14,43]. It is not difficult, technically, to create a DC-MG. To facilitate the success of this type of microgrids several requirements must be fulfilled:…”

The development of microgrids is of great interest to facilitate the integration of distributed generation in electricity networks, improving the sustainability of energy production. Microgrids in DC (DC-MG) provide advantages for the use of some types of renewable generation and energy storage systems, such as batteries. In this article, a possible practical implementation of an isolated DC-MG for residential use with a cooperative operation of the different nodes is proposed. The main criterion is to achieve a very simple design with only primary control in a residential area. This application achieves a simple system, with low implementation costs, in which each user has autonomy but benefits from the support of the other users connected to the microgrid, which improves its reliability. The description of the elements necessary to create this cooperative system is one of the contributions of the work. Another important contribution is the analysis of the operation of the microgrid as a whole, where each node can be, arbitrarily, a consumer or an energy generator. The proposed structures could promote the use of small distributed generation and energy storage systems as the basis for a new paradigm of a more sustainable electricity grid of the future.

“…(3) Mathematically the output power of PV modules is obtained by solar irradiance with respect to PV module surface area. The output power of PV panel is determined by following equations [40]: NCOT is the nominal cell operating temperature; T I is the total radiation in the solar cell considering normal and partial radiation.…”

The recent evolution in technology and lifestyle has been led to a dramatic increase in electricity demand so that the local communities are encountered with challenges of huge initial costs, and sustainable extension to a national grid. Here in this paper, a DC microgrid cluster with three small areas (A, B and C) is proposed. Control and power stability of small-scale electrical system using renewable resources is a big challenge. In this study, the operation of DC microgrid and behavior of the system at different operating conditions is evaluated under different condition of the solar radiation and temperature changes for specific time periods. The DC Converters with PI control strategies are integrated to control the system performance and load-power balancing. The DC bus voltage level is employed as an information carrier for controller to maintain operation stability, improve efficiency, and enhance the redundancy of a system. At the meanwhile, the Maximum Power Point Trucking Incremental Conductance (MPPT-IC) algorithm is applied to maximize the efficiency and regulate the output voltage of the PV system to desired DC bus voltage. The PV arrays with battery and bidirectional converter are simulated to overcome the intermittency problems of PV outputs. Some typical operation modes are simulated using MATLAB R /Simulink to confirm the proposed model preference compared to the literature.
