Multi Asset Scheduling mysterious issue

[victorgarcia98]

This morning @Flix6x @svenay and myself have been experimenting with the following problem involving the multi asset scheduling:

• Site capacity: 100kW
• 100kW/100kWh Battery starting at 0kW
• Curtailable Solar facility producing a constant power of 250kW (yeah, unrealistic)

The solar assets modeled as a infinitely large battery that can only produce up to 250kW and cannot consume. The battery is not enough so we expect the optimization to curtail the solar to respect the site power capacity.

We tried without relaxing the site capacity constraints and it didn't work. The thing gets interesting when we relax the site capacity the constraints adding site-consumption-breach-price and site-production-breach-price to the flex-context and the schedules become feasible (and the results make sense).

The accompanying flex-model/context are:

flex_model = [
    {
        "sensor": sensors["Test Battery"].id,
        "consumption-capacity": "100kW",
        "production-capacity": "100kW",
        "power-capacity": "100kW",
        "soc-at-start": 0.0,  # 100 kWh
        "soc-unit": "MWh",
        "soc-min": 0.0,
        "soc-max": 0.1,  # 100 kWh
    },
    {
        "sensor": sensors["Test Solar"].id,
        "consumption-capacity": "0kW",
        "production-capacity": "250kW",
        "power-capacity": "1000kW",
        "soc-at-start": 10000,  # 100 kWh
        "soc-unit": "MWh",
        "soc-min": -100000,
        "soc-max": 100000,  # 100 kWh
    }
]
flex_context = {
    "consumption-price": {"sensor" : price_sensor.id},
    "production-price":  {"sensor" : price_sensor.id},
    "site-production-capacity": "100kW",
    "site-consumption-capacity": "100kW",
    "site-consumption-breach-price" : "100 EUR/MW",
    "site-production-breach-price" : "100 EUR/MW"
}
