The cost mainly depends on the energy storage technologies and it is difficult to evaluate as it is influenced by several factors such as the storage type, the application requirements, the size and so on. However, the capital cost of the energy storage can be calculated in the ways such as cost per kW, per kWh and per kWh per cycle.
So the formula is simulate this circuit – Schematic created using CircuitLab This is typically measured with an 80% of the total load . For Example: if I had a power supply that outputs 150W and it consumes 275W my efficiency is 150/275=0.54545 or 55%
The investment cost of energy storage system is taken as the inner objective function, the charge and discharge strategy of the energy storage system and augmentation are the optimal variables. Finally, the effectiveness and feasibility of the proposed model and method are verified through case simulations.
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.
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.
