6 FAQs about [How to benefit from energy storage peak load regulation]
What is peak regulation?
Peak-regulation refers to the planned regulation of generation to follow the load variation pattern either in peak load or valley load periods. Sufficient peak-regulation capability is necessary for the reliable and secure operation of power grid, especially in urban regions with extremely large peak–valley load difference (Jin et al., 2020).
How effective is peak-load regulation capacity planning?
Based on probabilistic production simulation, a novel calculation approach for peak-load regulation capacity was established in Jiang et al. (2017), which is still effective for peak-regulation capacity planning when some information of renewable energy and loads is absent.
What is peak-regulation capability of a power grid?
Principle of the evaluation method The peak-regulation capability of a power grid refers to the ability of power supply balancing with power load, especially in the peak load and valley load periods. Specifically, the adjustment range of power supply in one day should be high enough to reach the peak load and low enough to reach the valley load.
Why do Load Serving Entities use energy storage?
They assume that the load serving entity operates this energy storage to harness simultaneously multiple streams of benefits: energy arbitrage, peak shaving, minimising deviations from the load forecast and regulation service.
How to provide peak load?
To provide peak load, a conventional approach involving capacity increase (small gas power plants and diesel generators) is traditionally used. However, this approach is not economically feasible and inefficient in the use of generators because it is used to maintain production capacity for only a few hours a day .
When should energy storage be used in summer?
Summer peak demands usually occur during the late afternoon or early evening. Storage can provide peak shaving benefits by discharging for just a few hours when the daily peak load is likely to happen. During the rest of the day, the dispatch of energy storage has no impact over the daily peak demand.
