6 FAQs about [Energy storage peak load ratio]
How can peak load and Peak-Valley difference be reduced?
The increase in peak load and peak-valley difference can be reduced through the allocation of centralised energy storage in transformer stations and the allocation of decentralised energy storage on lines and line upgrading. The algorithm method is as follows.
Can energy storage allocation and Line upgrading reduce peak load and Peak-Valley difference?
In this paper, a comprehensive configuration strategy of energy storage allocation and line upgrading has been proposed. This strategy can reduce the peak load and peak-valley difference caused by the rapid development of loads and the integration of a high proportion of PVs in distribution networks.
How to solve the problem of line overload caused by peak load?
Therefore, it is urgent to upgrade the lines and allocate energy storages to solve the problem of line overload caused by the increasing peak load and peak-valley difference. In case 2, there is no centralised or decentralised energy storage in the distribution network and distribution lines are only upgraded to adapt to the increase in peak load.
Why is energy storage important for large-scale re integration?
Energy storage significantly facilitates large-scale RE integration by supporting peak load demand and peak shaving, improving voltage stability and power quality. Hence, large-scale energy storage systems will need to decouple supply and demand.
How does demand response affect energy storage capacity allocation?
As an important and flexible adjustment method, demand response has been introduced into the research of optimal allocation of energy storage. Kou et al.

Do power supply side methods reduce peak load regulation?
Power supply side methods can effectively improve the consumption of DGs and reduce the peak load regulation problem in power systems. However, the peak load and large peak-valley difference in distribution networks caused by the integration of high proportion DGs are not reduced in refs. [8, 9].
