Do storage systems have a control strategy for voltage regulation?
Several voltage regulation techniques using active and reactive power can be found in the papers presented. However, no control strategy was found that searches for the least amount of active power coming from the storage systems for voltage regulation, a determining factor for the cost and service life of those storage systems.
What is distributed energy storage control?
Distributed energy storage control is classified into automatic voltage regulator and load frequency control according to corresponding functionalities. These control strategies maintain a power balance between generation and demand.
What is automatic generation control (AGC)?
As the grid transitions towards a more sustainable future, energy storage systems are becoming critical in managing the challenges that come with this change. Central to the operation of these systems is Automatic Generation Control (AGC), a technology that ensures the balance and reliability of power systems.
How does an AGC system work?
Signal Generation When a discrepancy is detected, the AGC system generates a control signal to correct the imbalance. Response by Energy Storage Energy storage systems receive the AGC signal and respond accordingly by either charging (storing excess energy) or discharging (releasing energy into the grid).
How does a voltage control system work?
A voltage control system presented by Carvalho et al. uses reactive power to maintain the supply voltage without major disturbances, even with the injection of the active power from the distributed generation.
How can a battery energy storage system improve power quality?
An algorithm is proposed by Lee et al. to control battery energy storage systems (BESS), where an improvement in power quality is sought by having the systems minimize frequency deviations and power value disturbances. As a result, the system acquires a smoother load curve, becoming more stable.
