Hi fellas,
First, I want to congratulate the NREL team for the excellent program they have developed.
I would need your help because I have some problems modeling my hybrid system.
I need to model a system that currently has PV+Wind, and I want to add batteries to it. To do this, I have combined the wind and solar productions into a 8760-value production matrix and introduced it into the system in the Generic-battery Merchant system.
Let me give you some context:
- Grid interconnection limit = 6 MW
- Nominal power PV+Wind = 10 MW
- Desired bank power = 2 MW
- Desired bank capacity = 2 hours
- I have input a matrix of random energy selling prices (25 years)
- The system cannot charge from the grid, only from the PV+Wind system
When I analyze the results, I realize that during moments of high prices, if the production from PV+Wind is, for example, 5764.66 kW, I only need the battery to provide me with 235.34 kW. However, it provides 2103.36 kW continuously. I don't understand why it keeps discharging 2103.36 kW repeatedly.
Attached, you will find the SAM model. I would appreciate it if you could assist me with this.
Thank you very much!
