Is there any efficient way of modelling electric vehicles that are connected to the system and operate as storage units when plugged in?
If you want to use electric vehicle as a storage module which when plugged in both charges and discharges to serve the load and if it's a grid connected system, you can use scheduled rates. This way you can prohibit the battery from charging or discharging during specific period in the day. If you just want to use the electric vehicle as a charging load, then you can model it as an additional load by modifying the load profile for specific period of the day when you want to charge it. Hope this helps.
For modelling EVs connected on the system, would it be possible to use a "deferrable load"? Using the procedure explained above, I think that it creates a fixed load profile, exactly as you set it. The idea would be to optimize the load (EVs charging or discharging to provide storage to the grid). Could anyone give some feedback whether what I'm thinking is correct or would lead to false results?
Thanks for your reply. Unfortunately my trial period expired. I tried in many different ways to model an EV charging station, but couldn't get it to work. Using a negative load would create a fixed negative load, not a battery storage that would normally charge and discharge when needed.
In any case I will give it another try if I get the chance.
