The battery acts as a bridge and intermediary, improving the photoelectric absorption and stability of PV-electrolysis hybrid systems . Due to the application of batteries, the power generated can be stored during periods when sunlight is sufficient.
The battery capacity directly affects the expenditure of the PV battery-electrolysis hybrid system. The installed electrolysis capacity can be reduced by configuring a certain amount of battery storage to be discharged for electrolysis during peak load periods. This reduces the overall capital expenditure of the entire system.
The battery provides a stable power supply for the PV-electrolysis system. Hence, this study proposes a robust model for configuring the capacity of a PV-battery-electrolysis hybrid system by considering the dynamic efficiency characteristics and cost learning curve effect of key equipments.
Based on the results compared with the fixed efficiency, it is evident that the dynamic efficiency characteristics of electrolysis have a significant impact on the configuration of the PV-battery-electrolysis hybrid system, reflecting the optimal economic characteristics of the system.
Actual output of 1 MW PV on typical days. Taking into full account the operating conditions of each equipment in the PV-battery-electrolysis hybrid system, the lifetime of the system is assumed to be 20 years; considering the time value of money, the investment cost is amortized each year through an annualized factor.
Considering the uncertainty of the PV output, a capacity configuration optimization model for a PV-battery-electrolysis hydrogen production system was developed.
