What determines the amount of energy storage required, as section 4 will show, is not the magnitude of demand or generation, but the penetration of renewables (percentage of total demand supplied by renewables) and the time-mismatch between these two profiles.
The ideal arrangement of energy storage relies on its utilization and is constrained to a maximum discharge duration of 5 h at full power, while the power discharged is restricted to 40 % of the nominal capacity of the photovoltaic (PV) system.
The energy-to-power ratio (EPR) of battery storage affects its utilization and effectiveness. Higher EPRs bring larger economic, environmental and reliability benefits to power system. Higher EPRs are favored as renewable energy penetration increases. Lifetimes of storage increase from 10 to 20 years as EPR increases from 1 to 10.
Integrating energy storage within power system models offers the potential to enhance operational cost-effectiveness, scheduling efficiency, environmental outcomes, and the integration of renewable energy sources.
For systems with less than 100% VRE (Variable Renewable Energy) penetration,\ the storage energy size is a function of VRE penetration. The storage capacity had to be the outcome of an optimization process. Therefore, studies like , , were excluded since they provide insight into the interaction of the variables, but do not give guidelines on what is the best choice.
For 100% renewable energy systems (power, heat, mobility), the storage requirement can be kept below 6% of the annual energy demand. Combination of sectors and diverting the electricity to another sector can play a large role in minimizing the storage size.
