At the same time, it also has the advantages of high energy storage density, long energy storage cycle, and low cost, making it one of the very promising peak shaving methods for thermal power units.
Heat storage technology presents a promising solution to this challenge, as it significantly enhances the flexibility of peak shaving in power stations and mitigates supply-demand imbalances within power grids .
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.
Peak 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.
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.
The peak power that can be reduced by an Energy Storage System (ESS) is limited by its energy storage capacity, maximum charge and discharge powers, and the load characteristics, which indicate how much energy the loads peak hold.
Several peak load shaving strategies can be utilized by industries to reduce their power peaks and thus the power tariff. The aim of this study is to economically analyze peak load shaving …
