The control design follows the consensus theory, originally designed for multi-agent systems, to control the frequency and voltage at the point of common coupling (PCC), synchronize energy levels, and proportionally share active and reactive powers of battery storage systems.
The simulation results revealed that the “priority regulation of pumped storage” control strategy has a better performance on active power balance, compared with the “priority regulation of battery storage” control strategy. This work could provide technical support for coordinated control of the practical PSBIS in the future.

How Pressure Mapping Insights Improve Battery Performance and Safety - Charging and discharging causes changes in temperature, electrochemistry, or volume expansion. Measuring changes in pressure can tell you how the mechanics of the internal components are affected.
At low flow rates, the battery module of the high porosity system has a higher maximum temperature in the early stage of discharge, while the maximum temperature in the later stage is lower. To better analyze the temperature change of the module, the battery discharge process is divided into three stages.
3. Humidity control To reduce the system complexity, two important functions – pressure balancing and emergency degassing – are com-bined into one unit. The unit has to ensure that no liquid water can enter the battery housing under all conditions. A PTFE membrane was validated for this application.
