To put it simply, peak shaving means reducing or smoothing out sudden spikes in electricity consumption (load peaks) to help balance supply and demand for energy in the power system.
Battery Energy Storage System (BESS) can be utilized to shave the peak load in power systems and thus defer the need to upgrade the power grid. Based on a rolling load forecasting method, along with the peak load reduction requirements in reality, at the planning level, we propose a BESS capacity planning model for peak and load shaving problem.
To summarize, when examining the optimal operation plan for each charging station in the distribution network participating in peak shaving, this paper conducts an initial assessment of the demand response potential of each charging station by considering both the electricity price response and the charging power response.
Since load forecasting is quite difficult to achieve, a battery can be used for peak shaving to help manage and mitigate the effects of peaks in energy demand. To be more specific, this method focuses mostly on dimensioning the battery for peak shaving.
The results demonstrate that batteries in peak shaving applications can shorten the payback period when used for large industrial loads. They also show the impacts of peak shaving variation on the return of investment and battery aging of the system. 1. Introduction
