Abstract: In order to make the energy storage system achieve the expected peak-shaving and valley-filling effect, an energy-storage peak-shaving scheduling strategy considering the improvement goal of peak-valley difference is proposed.
With the integration of renewable power generation units such as wind and solar power into the grid, coal-fired power units not only need to provide peak shaving ancillary services, but also has a downward trend in its own annual power generation hours. It is urgent to measure and evaluate the peak shaving costs of coal power.
A novel peak shaving cost calculation model is proposed for coal-fired power plants. Minutes-level operational data are used to analyze peak shaving costs and profits. Coal-fired power plants may not benefit under the current compensation mechanism. The economic comparison between different coal prices for peak shaving.
Opportunity loss for deep peak shaving The increasing peak depth of coal-fired power units will significantly reduce the power transmission, resulting in a loss of electricity revenue, which is called the peak-shaving additional revenue loss.
Finally, taking the actual load data of a certain area as an example, the advantages and disadvantages of this strategy and the constant power control strategy are compared through simulation, and it is verified that this strategy has a better effect of peak shaving and valley filling.

Implementing measures to save energy Another important step in reducing peak loads is to optimise the energy efficiency of the entire system. If the individual consumers require less power, this relieves the load on the entire system and reduces the likelihood of peak loads. Use of battery storage for peak shaving
Randomness and intermittency of renewable energy generation are inevitable impediments to the stable electricity supply of isolated energy systems in remote rural areas.

Peak-shaving involves reducing the amount of electricity drawn from the grid during peak demand times, typically late afternoons and early evenings when energy use is highest. By harnessing solar power and storing excess energy in batteries, homeowners can decrease their reliance on the grid during these expensive periods, thus reducing electricity costs.
Then, considering that the pumped-storage power station has both source-load characteristics, the peak-shaving value of the pumped-storage power station is deeply excavated to share the peak ...
Peak shaving works by recognizing these high-demand durations and tactically handling energy intake to decrease the top lots. This can be attained via various approaches, such as using backup generators, moving non-essential energy use to off-peak times, or implementing power storage services like batteries.
