Grid Management
Eaton enables the integration of utility grade battery systems onto the AC grid with the Power Xpert Storage energy storage grid-tie inverters. Power Xpert Storage inverters provide the link for bi-directional flow of energy from grid to battery and battery to grid.

Many of today’s utilities with significant wind and solar penetration face the following challenges:

• Poor location of generation
• Variability and uncertainty of generation
• Insufficient control over generation

Energy storage provides utilities with solutions to these and other challenges through grid management features, such as peak power shaving, load leveling and grid stabilization.

Peak Power Shaving
Congested corridors where distribution replacement costs are high are prime candidates where energy storage systems can be applied. Stored energy can make up the difference between power distribution limits and high peak load demands.

Load Levelling
Customer owned storage enables avoidance of peak demand charges. Utility owned load levellers help defer costs of new generation and/or distribution.

Grid Stabilization
With high penetration of alternative energy, generation utilities experience a high rate of power change (ΔP/Δt) due to wind shifts or rapid cloud cover, making it difficult for existing grid generation to keep up. This often results in voltage and frequency instability. With Eaton’s Series 6001 grid-tie inverters, batteries can respond from full charge to full discharge power within one AC cycle, providing rapid response energy damping to fast shifting demands.

Time-of-use load shifting
Time of use metering has become prevalent in many utilities. Customers can now charge battery systems during off peak hours and discharge them during high peak hour charge times of the day, thereby reducing overall energy costs for hard-to-shift time-of-use loads.
