To explore the application potential of energy storage and promote its integrated application promotion in the power grid, this paper studies the comprehensive application and configuration mode of battery energy storage systems (BESS) in grid peak and frequency regulation.
On the contrary, electrical energy can be purchased from the main grid at off-peak times when the per-unit electricity cost is comparatively low and can store the energy using ESS. Generally, the cost of electricity is very high during peak hours. The stored energy can be used to deal with excessive demand or can be sold to the main grid.
Midday to evening is the peak load period, where BESS is used for discharging to relieve the pressure of peak power consumption. The interval of PSVF applications can be used for FR. The overall regulated power has a maximum unidirectional demand of around 45 MW and a short duration, while most power demand falls within 20 MW.
With a reinforced power grid, regional overproduction can be compensated for by energy transmission to temporarily less productive areas. The amount of energy storage can also be reduced by overinstallation of renewable energy generators. With this approach even weakly producing periods are adequate for the load expected.
Operating the electrical grid has never been simple, but today the balance of supply and demand is getting more complex. On the supply side, the increasing penetration of renewable and distributed energy sources, such as solar and wind power, makes peak load management more complex.
Nonetheless, the emphasis on peak load management will only increase in scale and sophistication. To better predict and prepare for the rapidly changing energy landscape, this editorial discusses the past and present state of peak load management and how it might be evolving into more flexible load management.
