This paper proposes a distributed economic power dispatch (EPD) and bus voltage control solution for droop-controlled DC microgrids. For the proposed solution, a local power controller and a local voltage controller are added for each distributed generator (DG) to overcome the limitations of the conventional droop control. The power controller generates the first voltage correction term by comparing the local output power of DG with the reference instruction generated by the proposed distributed EPD algorithm, and thus, it can reduce the operation cost of the microgrid by optimally sharing the load demand among all the participating DGs. The voltage controller generates the second voltage correction term by comparing the nominal DC bus voltage value with the average bus voltage generated by the proposed distributed average bus voltage observation (ABVO) algorithm, and thus, it can realize the global bus voltage regulation of the DC microgrid. In contrast with conventional solutions, the control solution can distribute the computational and communication burdens among all the DGs working in parallel, which is more flexible, scalable, and robust against single-point failure. The effectiveness of the proposed control solution is demonstrated through simulation studies.

“…The system's main task is to consider islanding and reconnecting to the grid under power quality problems. [ 34 ] The existing studies show that FCVs are used various functions like energy balancing, integration with renewable energy sources, and grid support. Further, in almost all of the investigated systems, the researchers deal with topologic and functional advancements.…”

The investigation of fuel cell vehicles (FCVs) connected to grid (FCV2G) technology regarding the reduction of consumer costs is proposed. Herein, the key contribution is to investigate the energy and profit analysis aspects of an FCV2G system supported by photovoltaic (PV) panels for a 24 h operation. For this, an FCV in the rating of 100 kW is connected to the grid/homes, and a detailed analysis is performed for the FCV2G system supported by PV energy in the rating of 40 kW. The designed system is primarily tested for energy transfer from FCV/PV to grid/homes, and the results are verified for dynamic loading situations. It is observed that FCV + PV supply excess power to the grid during flexible hours of the day, and consumer homes use additional energy from the grid during peak hours. The profit analysis of the established FCV2G system is conducted using the load profile data for the 24 h situation. FCV2G supported by a PV system verifies that the homes' consumption cost is reduced significantly, and the remaining energy is utilized by selling the energy to the grid.

“…They have been attracting much research interest due to their potential to increase energy security and reliability, as well as foster the penetration of distributed renewable resources (e.g., wind, solar) and distributed storage (e.g., plug-in vehicles, community energy storage) [2][3][4][5][6][7][8][9][10][11]. Because of this potential, the U.S. Department of Defense (DoD) is interested in microgrids as indicated by the SPIDERS (Smart Power Infrastructure Demonstration for Energy Reliability and Security) project, which aims to demonstrate the first complete DoD installation with a secure microgrid capable of islanding.…”

Increasing concerns about energy security and reliability are intensifying the military's interest in the microgrid technology. This paper focuses on the frequency and voltage regulation part of a case study that seeks to design a conceptual military microgrid that has to operate completely autonomously. This microgrid comprises a solar panel and vehicles as power sources, where the vehicles contain a battery and generator, and managing their power setpoints is the control problem of interest. The goal is to investigate the validity of assuming the battery as a constant voltage source during the control design. To this end, the control design is first carried out assuming the battery as a constant voltage source. It is then illustrated how critical this assumption can be depending on the battery internal resistance. The results show that the battery internal resistance can affect both frequency and voltage regulation performances, thereby highlighting the coupling between the battery characteristics and control design, and the need for a control design framework that takes this coupling into account.
