Hybrid Grid benefits to grid stability
▪ Frequency outside the acceptable range creates grid instabilityand potential black-out
▪ Battery storage absorbs or supplies immediately power from/to the grid depending on frequency variation.
Frequency Regulation
▪ Distributed solar generation impacts locally voltage level with potential overvoltage issues and unexpected load shedding
▪ Power electronic deployed with storage can regulate grid voltage locally by controlling reactive power from/to the grid.
Voltage Support
▪ Power failures are particularly critical at industries and sites where the environment and public safety are at risk, generating additional costs.
▪ Battery storage can provide black start or grid islanding to restart load and local generation for reliable grid forming.

Battery = Fast & efficient grid service provider to leverage multiple revenue stream
