The software allows a project developer to define how often the charging station is in use through average charge duration time and traffic density over the course of the year.HOMER Grid also incorporates characteristics of the EV charging station, such as the maximum charge rate of EV station connector (kW). The smart charger allows project developers to leverage HOMER Grid’s capability to model demand charge reduction in any distributed renewable energy system and apply this to an EV charging station.The EV Charging Design Tool in HOMER Grid accepts inputs to describe vehicle types and charging requirements, such as EV battery size (kWh) and maximum charge rate (kW). It prioritizes the use of renewable power and schedules charging to take advantage of grid electricity when it is at its lowest cost.
According to the Boston Consulting Group, sales of EV vehicles, including both plug-in hybrid and battery-only vehicles, will account for a third of all auto sales by 2025, and outpace sales of internal combustion vehicles by 2030. It can also solve for systems with the lowest carbon emissions and other factors.The EV market, which has been growing at more than 50% annually since 2013, is now expanding faster than expected. It also allows users to simulate control strategies to dispatch power to the EV charging station that matches their specific circumstances.The software generates powerful simulation reports that show how the various resources are dispatched in a given system and produces professional-looking proposals that can be used to communicate clearly with diverse team members, potential investors and clients, or other stakeholders.Developed primarily for commercial and industrial users, HOMER Grid software helps reduce financial and engineering risk through feasibility simulation of multiple system configurations and identification of least-cost options. It then models technologies such as solar, wind, batteries, or combined heat and power (CHP), and calculates the optimal system configuration with the lowest cost.
HOMER Grid, aimed at the behind-the-meter solar-plus-storage market, helps commercial and industrial customers design hybrid renewable energy systems that save on electricity bills and lower carbon footprints. HOMER® Pro simulates the engineering and economic feasibility of complex off-grid and grid-tied distributed energy systems that combine conventional and renewable power, storage, and load management. EV charging can be equivalent to the peak demand of an entire house, and demand charges can make up over 50% of a commercial electric bill.HOMER Energy by UL is the developer and distributor of HOMER software, a global standard for energy modeling tools that analyze solar-plus-storage, microgrids, and other distributed energy projects. The demand for charging stations is, in turn, driving demand for the design of distributed renewable energy systems that can produce clean power for transportation.Meanwhile, according to an article by the Rocky Mountain Institute, EV charging station owners and the commercial buildings where they are located could face “runaway electric bills” if EV charging is not managed carefully.
