In avoid overchargng and overdischaging of the energy storage system. Despite the fact that constant- discharging, other methods such as FLC or MPC have shown better performances. The main benefits keeping the battery SOC within secure limits. Moreover, the reduction o the investment cost in energy storage capacity and the life expectancy increase.
What is a sufficient charging/discharging at design conditions?
A clearly defined sufficient charging/discharging at design conditions is a point in the phase space (noted by the star in green), while the rest of the space can be referred to as “off-design conditions”. For example, two dashed curves are given for off-design charging and discharging.
Should energy storage systems be treated seriously?
Remarkable reductions in density and power should be considered seriously. If not well treated, it would bring some uncertainty and insecurity to larger-scale electricity grids. More importantly, this could fundamentally deteriorate the economic performance of an energy storage system over a long period.
Why is energy storage important?
Energy storage has become a fundamental component in renewable energy systems, especially those including batteries. However, in charging and discharging processes, some of the parameters are not controlled by the battery's user. That uncontrolled working leads to aging of the batteries and a reduction of their life cycle.
