Energy storage can provide time-of-use electricity prices

Do storage systems influence electricity prices?

In the existing TOU pricing models for instance, interactions with other sources of power system flexibility such as storage devices and electric vehicles have never been studied even though bulk storage systems and plug-in electric vehicle operations may influence grid stability and electricity prices.

Should energy storage system be charged while supplying electricity?

If is within the power supply capacity of the interconnection line, the external power grid should consider charging the energy storage system while supplying electricity; When is less than zero or greater than zero and less than , this situation mainly relies on the energy storage system to maintain the balance of .

Can dynamic time-of-use electricity prices improve energy storage capacity?

Using dynamic time-of-use electricity prices can more flexibly obtain the capacity configuration scale of energy storage. The article adopts the capacity and maximum power values of energy storage configuration in each season, which can meet the demand for energy storage capacity in each season.

How can energy storage devices improve on-site energy consumption?

Author to whom correspondence should be addressed. Configuring energy storage devices can effectively improve the on-site consumption rate of new energy such as wind power and photovoltaic, and alleviate the planning and construction pressure of external power grids on grid-connected operation of new energy.

What is the objective function of energy storage?

The objective function is to coordinate and optimize the capacity and maximum charging and discharging power of the energy storage system, taking the on-site consumption rate of new energy and the optimization configuration cost of energy storage as the objective functions.

Can energy storage capacity be allocated in wind and solar energy storage systems?

This article studies the allocation of energy storage capacity considering electricity prices and on-site consumption of new energy in wind and solar energy storage systems. A nested two-layer optimization model is constructed, and the following conclusions are drawn:
