How residential energy storage could help support the power grid. Household batteries could contribute to making the grid more cost effec- tive, reliable, resilient, and safe—if retail battery providers, utilities, and regulators can resolve delicate commercial, operational, and policy issues. by Jason Finkelstein, Sean Kane, and Matt Rogers.
Grid interactions can be avoided for most of the time with a storage capacity of 5%, which for this research corresponds to approximately 163 kWh net storage capacity per household. This order of magnitude storage capacity largely exceeds typical current household-scale EES options or EES capacities of electric vehicles ( IRENA, 2017 …
The power electronic converter interface between battery storage and the power grid faces several challenges and limitations discussed in Refs. [ 129, 130 ]. One of the main limitations is the increased complexity in the gate drive circuits when using two-level topologies for direct connection to the medium voltage (MV) grid.
Current literature mostly focuses on how the storage mix is affected by the renewable mix, but few studied the inverse impact and the dynamic interaction between the storage and renewable mixes.
