How to analyze batteries and storage?

The analysis of batteries and storage depend on load shapes and the value of power during different time periods. To model the use of batteries you will need some kind of battery dispatch analysis where you decide when to charge and when to discharge the batteries.

What are the economics of battery storage?

The economics of storage depend on the cost of charging a battery versus the value from discharging the battery. In this case the way the battery storage is set-up is to discharge only during on-peak periods.

What are some examples of economic issues associated with battery analysis?

hypothetical example is in my opinion an effective way to illustrate many of the economic issues associated with battery analysis. It involves solar analysis, the cost of diesel fuel, the demand patterns of people who live on an island and the kind of batteries that would be most effective.

How do you calculate battery costs?

Batteries costs and other parameters are a function of the amount of hours of storage — the costs are generally expressed in kWh. In measuring costs and benefits, you need the amount of hours of storage relative to the capacity or load.

How do you measure costs and benefits of a rooftop solar system?

In measuring costs and benefits, you need the amount of hours of storage relative to the capacity or load. Another model addresses how to create a simple model of including batteries with solar in for a residential rooftop.

When should a solar battery be charged?

If the battery is part of a micro-grid system without on-peak and off-peak rates, the battery should charge when there is more solar production than load and it should discharge when the load is greater than the solar production. In the example below, the battery is charged from surplus renewable production above the needs of the data center.
