What is peak shaving?

The process of reducing electrical power consumption during periods of high demand is called peak shaving. Utilities adapt the peak loads on the demand side with the end-users’ participation , , on the generation side (e.g., dispatchable power plants) and by grid upgrade measures , .

Should Bess achieve peak shaving without increasing energy procurement costs?

Particularly, the BESS should achieve peak shaving without increasing the energy procurement costs. Moreover, the robustness of a peak shaving strategy has to be ensured for various load forecasting error levels, since high inaccuracies can lead to low peak reductions.

Will peak shaving save a lot of money in 2022?

Concerning the BESS control scheme, the relative savings from peak shaving can increase year by year ranging from 48% in 2019 to 78% in 2022 compared to the theoretical optimum with perfect forecast.

How robust is peak shaving strategy for load forecasting error levels?

Moreover, the robustness of a peak shaving strategy has to be ensured for various load forecasting error levels, since high inaccuracies can lead to low peak reductions. Hence, it is a challenge for the grid operator to utilize optimally a stationary BESS for peak shaving. 1.2. Literature review

How much does peak shaving save compared to day-ahead load forecast?

In particular, the relative savings from peak shaving increase from 44% in 2019 to 62% in 2022 when using the day-ahead load curve forecast. Moreover, the respective values with the use of day-ahead peak load forecast range from 48% in 2019 to 78% in 2022.

How do you calculate peak shaving?

For peak shaving, there are no requirements to be fulfilled, therefore the new annual peak load P c o n, m a x, n e w, x is calculated bei reducing P c o n, m a x till P c o n, a v g is reached ( x ≤ P c o n, a v g ), because a constant load reference would exist from this point on (see formula 6). (6) P c o n, m a x, n e w, x = P c o n, m a x − x
