What is peak-load shifting?
Peak-load shifting refers to the process of mitigating the effects of large energy load blocks during a period of time by advancing or delaying their effects\. This process aims to minimize generation capacity requirements by regulating load flow in the power supply system.
What is peak shifting and how does it work?
Peak shifting is a concept that can help address the issue of high energy demand during peak hours with a different approach: generation shifting. This means that Energy Storage Systems (ESS) not only help end users reduce their costs, but also enable generators to access a higher value of dispatchable generation.
How do energy storage systems reduce generation capacity requirements?
Energy storage systems (ESSs) help in reducing generation capacity requirements by shifting the load profile as seen by the generators (see Figure 1). The traditional intent behind this process is to accomplish this when the loads themselves cannot be regulated.
How can energy storage systems reduce peak demand?
Energy storage systems can help reduce peak demand by charging during off hours and discharging during operational hours. This can result in lower peak demand charges from the utility.
Can energy storage be used during peak PV generation?
During peak PV generation, excess energy can be stored for later use. This allows for the distribution of this energy when the PV system is not generating adequate power, or not generating at all. Energy storage is also used for peak smoothing with renewable generation.
How can building owners reduce energy load?
Engineers should provide building owners with the ability to shift their energy load from peak to off-peak hours using energy storage systems. Learning objectives: Understand the basics of peak load shifting using energy storage systems.
