Peak load shaving is one of the applications of energy storage systems (ESS) that will play a key role in the future of smart grid. Peak shaving is done to prevent the increase of network capacity to the amount of peak demand and also increase its reliability.

Moreover, wind power, nuclear power, and other new energy

Determined by the energy structure of power generation in China, the main means of peak load shifting in traditional power grids include thermal power and gas-fired units for peak shaving. However, these approaches necessitate not only accurate grid load forecasting but also sufficient peak shaving standby capacity from generating units [

Only 29% of the total electricity generation came from renewable sources, the main power plants are still thermal energy-based power plants. Moreover, large-scale integration of renewable energy resources would result in a mismatch between demand and supply, and threaten the security operation of the electricity grids due to their unpredictable and

We find that the addition of renewable generation can significantly increase storage''s potential by changing the shape of net demand patterns; for example, beyond

Baseload is a concept that describes a characteristic of the power demand side, and not a necessity of the supply side. In the example in Figure 1, baseload is about half peak load capacity. this illustrates that, for a typical power system, baseload constitutes more than half of total annual electricity demand.

Battery storage is increasingly competing with natural gas-fired power plants to provide reliable capacity for peak demand periods, but the researchers also find

With peak shaving, a consumer reduces power consumption (" load shedding ") quickly and for a short period of time to avoid a spike in consumption. This is either possible by temporarily scaling down production, activating an on-site power generation system, or relying on a battery. In contrast, load shifting refers to a short-term reduction in

Grid energy storage is used to shift generation from times of peak load to off-peak hours. Power plants are able to run at their peak efficiency during nights and weekends. Supply-demand leveling strategies may be intended to reduce the cost of supplying peak power or to compensate for the intermittent generation of wind and solar power.
