This paper proposes a peak-shaving and valley-filling dispatching approach based on a multi-agent system (MAS) to enhance both the regulatory capability and economic efficiency of power grids. . To address these challenges effectively, this study applies the deep reinforcement learning model in power system elastic scheduling optimization. The approach combines large-scale. . Under the backdrop of the “dual carbon” strategy, the rapid increase in renewable energy penetration has exacerbated challenges such as widening peak–valley load gaps and insufficient grid regulation capacity, highlighting the urgent need to establish a market-oriented collaborative dispatching. . Towards the dual-carbon goals, the new urban power grid (NUPG) dominated by new energy has a low proportion of adjustable power generation units, resulting in insufficient scheduling flexibility.

Peak shaving is the process of reducing a facility's maximum power demand during periods when electricity prices are highest, typically late afternoon. Benefit: By using stored energy during peak hours, businesses can significantly lower their demand charges, as they are. . In markets such as China, Europe, and North America, the peak-to-valley price ratio can reach 3:1 or even higher. Over time, this erodes profits and limits production. . In an era of rising electricity costs, unpredictable peak demand charges, and growing pressure for energy independence, peak shaving energy storage is no longer a luxury—it's a necessity. Peak demand occurs in the morning and evening, straining the grid and risking outages when supply can't meet demand.

How does frequency regulation affect hybrid energy storage system scheduling?
Auxiliary service effect of frequency regulation. Hybrid energy storage system scheduling result of frequency regulation. MG needs to dispatch HESS frequently according to the Reg-D signal when participating in the power grid frequency regulation service, which poses a challenge to the economic operation of BES and FES.
Battery energy storage systems reduce peak demand by supplying stored electricity during periods of high load instead of drawing additional power from the grid. During off-peak hours or periods of low production, the system charges the batteries. These strategies are especially powerful when combined with battery energy storage systems (BESS). Additionally, these systems serve as reliable backup power sources, ensuring production continuity. . Peak shaving is about reducing energy consumption during peak demand. An energy storage system (ESS) is charged while the electrical supply system is powering minimal load at a lower cost of use, then discharged for power during increased loading, while costs are higher, reducing peak demand utility charges.
