The optimization is similar to the one done for solar-only projects, with a minor increase in complexity to account for the state of charge of the energy storage. The inverter loading ratio determines the amount of additional energy that can be cost-effectively sold.
Determine how much energy is delivered for each increase in inverter loading ratio. For example, if the total energy delivered for a 1.6 inverter loading ratio is 254,400 MWh and for a 1.7 inverter loading ratio is 269,600 the marginal change in energy delivery is 269,600 MWh - 254,400 MWh = 15,200 MWh.
Researchers in Ireland have proposed, for the first time, a deterministic approach for designing inverter loading ratio (ILR) in utility-scale PV projects. The novel methodology is claimed to simplify the design process and reduce performance variability, while enhancing investment certainty. plant optimal design flowchart
We recommend you start with the inverter loading ratio you would use without storage, which is commonly 1.3. The simplest analysis for each hour would be: Note: Battery capacity will need to account for the battery power ratings and hourly state of charge. Detailed analyses should also account for losses of the different equipment.
