How is the energy storage charging pile factory of Maldives microgrid system . energy resource (DER) assets that are included, such as generation resources and battery storage systems, as well as the control architecture, load management systems, and level of automation of the microgrid, all of which increase complexity and cost of development.
When the microgrid's energy generation exceeds all the loads on it, the microgrid can charge its energy storage devices, such as batteries, via a bidirectional AC/DC converter. The use loads (both AC and DC) are connected to a common AC bus (backbone network). Microgrids can also send out (export) energy to the utility power grid.
Batteries can be used to provide ancillary services within a microgrid. Large-scale storage technologies, such as hydro-based or thermal storage, while cheaper for time shifting operations, have high initial costs that make their implementation in smaller and microgrids challenging.
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.
In commercial/industrial and utility microgrids, soft costs (43% and 24%, respectively) represent significant portion of the total costs per megawatt. Finally, energy storage contributes significantly to the total cost of commercial and community microgrids, which have percentages of 25% and 15%, respectively, of the total costs per megawatt.
By arranging to charge piles of different types and capacities in different microgrid areas and formulating different charging price strategies, it can satisfy the differentiated demands of EVs users, promote EVs users to reduce charging costs through orderly charging, and help the rapid development of electric vehicles.
The reduction in microgrid operation costs is directly reflected in the fast/slow charging prices, which greatly reduces the EVs charging cost. Although there are also certain transfer power consumption costs and queuing time costs, the total cost of EVs is reduced by 55.2% compared with scenario 3 and 44.3% compared with scenario 1.
