For storage it is assumed that solely the cumulated stored energy determines the LCOE of the storage system. It turned out that C rate is the most important parameter for the LCOE of storage. In contrast, the efficiency plays a less dominant role as often assumed in current technology discussions.
ount of electrical energy used during one 3-mo th period was 800 kilowatt-hours. Electrical energy costs 15p per kilowatt-hour.Use the equation in the box t electricity supply.total cost=number of kilowatt-hours×co t per kilowatt-hourShow clearly how you work out your answer and give the unit........................................
The total lifetime cost is the sum of the cost of PV energy generation and the cost of storage. The energy output of the PP is the sum of directly used energy from PV and the amount that is taken from PV to the storage system and then released to the output of the PP.
In the first part the general relations for PV and storage were derived and various parameter variations were discussed for both systems separately. For storage it is assumed that solely the cumulated stored energy determines the LCOE of the storage system. It turned out that C rate is the most important parameter for the LCOE of storage.
A storage device, by definition, cannot generate energy. Therefore, an internal transfer price pint,t weighs the value of the stored energy per period and pint,0 is the internal price at the beginning of the period.
