Customer ServiceUnvarying power plants provide base load generation. These plants typically run at full capacity all the time. They usually only power down for maintenance. They therefore tend to have a high capacity factor, which is the ratio of actual output to theoretically possible output.

Customer ServicePeak shaving can help reduce energy costs in cases where peak loads coincide with electricity price peaks. This paper addresses the challenge of utilizing a finite energy storage reserve for peak shaving in an optimal way.
This paper discusses the challenge of optimally utilizing a finite energy storage reserve for peak shaving. The Energy Storage System (ESS) owner aims to reduce the maximum peak load as much as possible while preventing the ESS from being discharged too rapidly (resulting in an undesired power peak).
Peak shaving refers to the practice of reducing electricity demand during peak hours to prevent overloading the power grid. It can also be used by utilities or renewable energy plants to increase the capacity of the existing grid infrastructure by deferring T&D upgrades into the future, providing a more cost efficient upgrade path for the power system. Fig.1 illustrates the principle of peak shaving, where the area corresponds to power x time, i.e., energy.
However, the demand for ES capacity to enhance the peak shaving and frequency regulation capability of power systems with high penetration of RE has not been clarified at present. In this context, this study provides an approach to analyzing the ES demand capacity for peak shaving and frequency regulation.
In peak shaving, energy storage performs peak shaving but an effort is made to charge the battery whenever possible. In contrast, in standby mode, the energy storage system is inactive and no charging or recharging occurs.
One of the main challenges of real-time peak shaving is to determine an appropriate threshold level such that the energy stored in the energy storage system is sufficient during the peak shaving process.
