How is energy storage capacity calculated?
The energy storage capacity, E, is calculated using the efficiency calculated above to represent energy losses in the BESS itself. This is an approximation since actual battery efficiency will depend on operating parameters such as charge/discharge rate (Amps) and temperature.
How is energy storage life determined?
The energy storage life is also determined by the actual operation strategy of energy storage; and in order to determine the operation strategy of energy storage, the configuration capacity of photovoltaic and energy storage must be given first.
Does energy storage capacity affect annual comprehensive cost?
The annual comprehensive cost is positively related to energy storage capacity when adopting pricing scheme 1, namely when the peak-to-valley price difference shrinks to a certain extent, consumers cannot obtain economic benefits by configuring energy storage.
What is the maximum energy accumulated in a battery?
The maximum amount of energy accumulated in the battery within the analysis period is the Demonstrated Capacity (kWh or MWh of storage exercised). In order to normalize and interpret results, Efficiency can be compared to rated efficiency and Demonstrated Capacity can be divided by rated capacity for a normalized Capacity Ratio.
What should be considered in the optimal configuration of energy storage?
The actual operating conditions and battery life should be considered in the optimal configuration of energy storage, so that the configuration scheme obtained is more realistic.
