Considering the power interdependence among the microgrids in commercial, office, and residential areas, the fast/slow charging piles are reasonably arranged to guide the EVs to arrange the charging time, charging location, and charging mode reasonably to realize the cross-regional consumption of renewable energy among multi-microgrids.
The proposed control methodology for controlling the charging/discharging of the microgrid storage system has been numerically implemented and tested on a simulated MATLAB model of the grid-connected microgrid using real location data. This model has been run online using the main software of the control methodology.
This paper provides a critical review of the existing energy storage technologies, focusing mainly on mature technologies. Their feasibility for microgrids is investigated in terms of cost, technical benefits, cycle life, ease of deployment, energy and power density, cycle life, and operational constraints.
Therefore, the proposed two-layer model realizes the optimal configuration of fast/slow charging piles in multi-microgrid areas, effectively reduces the EVs charging cost, reduces the impact of the EVs charging load on microgrids, improves the operation safety of microgrids, and increases social welfare. Table 8.
Microgrids are small-scale energy systems with distributed energy resources, such as generators and storage systems, and controllable loads forming an electrical entity within defined electrical limits. These systems can be deployed in either low voltage or high voltage and can operate independently of the main grid if necessary .
Scheme of the proposed microgrid description The storage system of the battery bank and the fuel cell is an essential part of the energy system that offers a more effective solution for achieving minimum operating cost under uncertain conditions.
