Load shifting works in conjunction with energy storage systems (ESSs) to optimize energy consumption, reduce costs, and enhance grid stability. Here’s a detailed overview:
How Load Shifting Works with Energy Storage Systems
Basic Principle
- Load Shifting: This involves moving electricity consumption from peak hours to off-peak hours. Energy storage systems play a crucial role in this process by storing excess energy during periods of low demand and releasing it during peak times.
Process of Load Shifting with ESSs
- Charging During Off-Peak Hours: During off-peak hours, ESSs, such as battery energy storage systems (BESS), are charged with electricity when it is less expensive. This electricity might come from the grid or be generated from renewable sources.
- Discharging During Peak Hours: When electricity demand peaks and prices increase, the stored energy is discharged from the ESSs to support the load, thus reducing the need to draw expensive peak-time electricity from the grid.
Benefits of Load Shifting with ESSs
- Cost Savings: Reduces electricity bills by utilizing cheaper off-peak energy and minimizing peak demand charges.
- Grid Stability: Helps in stabilizing the grid by mitigating peak demand spikes and ensuring supply security.
- Renewable Energy Integration: Facilitates greater integration of renewables by buffering against their intermittent output.
Examples of Load Shifting with ESSs
- Industrial Applications: Manufacturing facilities can optimize energy use by charging their on-site BESS overnight and using the stored energy during daylight hours when industrial operations are active.
- EV Charging Stations: Electric vehicle charging can be shifted to off-peak hours, with stored energy used during peak hours to support EV charging load.
In summary, load shifting, enabled by energy storage systems, is an effective strategy for managing energy costs and supporting grid resilience.
