Energy storage power supply side

What is energy storage?

Energy storage, as a “buffer” between the uncertainty of power generation and the disorder of load use in the Energy Internet, is its key supporting technology. Unlike the large-scale centralized energy storage on the power supply side and the grid side, distributed energy storage is usually installed on the user side or in the microgrid.

How to plan the energy storage system on the user side?

For the planning of the energy storage system on the user side, the main problems are: Li D et al. [ 9] consider the annual comprehensive cost of installing the energy storage system and the daily electricity charge of users and establish a two-level optimization model.

Can electrical energy storage solve the supply-demand balance problem?

As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system, Electrical energy storage (EES) technologies are increasingly required to address the supply-demand balance challenge over a wide range of timescales.

How is the load supplied by the superior power grid?

The load is supplied by the superior power grid separately from 01:00 to 05:00. During the period from 06:00 to 08:00, the load is transferred by the power flow. Period of 09:00 and during the period 18:00–19:00, the load is jointly supplied by the renewable energy, energy storage or/and power flow transfer.

When should a small energy storage device be submitted to a platform?

User-side small energy storage devices as well as the power grid need to be submitted to the platform before the day supply/demand power information. The platform side needs to sort out the total supply of power and total demand power information for each time period and release the information.

How can a power supply be used to reduce electricity consumption?

It can be used to cope with the peak load regulation of new energy access, store excess renewable energy, or modify the user load curve to reduce electricity consumption [ 4 ]. Industrial and commercial users consume large amounts of electricity and have high requirements for a stable power supply.
