Abstract
A method for determining use of a second life battery under load conditions to reduce CO2 emissions includes using Monte Carlo simulations to modeling uncertainties of a load profile, a renewable energy profile, and CO2 emissions rate, determining an initial state of charge SOC of the second life battery based on a Gaussian distribution for determining a rate of charging during low emission hours and discharging during high CO2 emission hours of the second life battery and storage size of the second life battery and CO2 emissions reduction.
Claims7
A method for determining use of a second life battery under load conditions to reduce CO2 emissions, said method comprising the steps of:
- modeling uncertainties in a forecast of a load profile to which said second life battery is using a Monte Carlo simulation for a load profile;
- modeling uncertainties of a renewable energy profile which is zero emission power profile using a Monte Carlo simulation to forecast availability of said renewable energy at different points of a day to charge said second life battery;;
- modeling uncertainties in CO2 emissions rate using a Monte Carlo simulation for a CO2 emissions profile;
- determining an initial state of charge SOC of said second life battery based on a Gaussian distribution;
- and
- using said load profile, CO2 emissions profile, renewable energy profile and modeled initial state of charge SOC of second battery life for determining a rate of charging during low emission hours and discharging during high CO2 emission hours of said second life battery, and determining storage size of said second life battery and CO2 emissions reduce
