Functions of intelligent energy storage controller

Can a battery energy storage system control low-frequency oscillations?

The motivation for the current study is to address low-frequency oscillations by proposing a battery energy storage system (BESS) controller. The BESS is connected to the power system through a DC/AC voltage source converter, which is a common configuration for grid-connected BESS systems.

Why are energy storage systems used in modern power systems?

In modern power systems, energy storage systems (ESSs) are widely used for various purposes, including stability improvement [25, 26], enhancing system self-sufficiency [27, 28], frequency control [29, 30], power quality enhancement , and reliability improvement .

Why do we need a storage system?

Due to the random nature of renewable energy sources, the continuous flow of energy all the time is impossible. Therefore, integrating a storage system is necessary in order to ensure the continuous flow of energy to the loads. A bidirectional DC/DC converter is usually used for control and management the power flow in the system.

What is a battery energy storage system (BESS)?

Battery energy storage systems (BESSs) have recently been utilized in power systems for various purposes. Integrating these devices into power systems can enhance the damping capability of subsynchronous oscillations.

Why is integrating a storage system necessary?

Therefore, integrating a storage system is necessary in order to ensure the continuous flow of energy to the loads. A bidirectional DC/DC converter is usually used for control and management the power flow in the system. This converter is controlled by generating a PWM signal.

Can a logical controller regulate energy distribution?

The current study used an obscure logical controller to regulate energy distribution within the proposed system. The system consists of electricity-producing sources comprised of wind turbines, solar panels, and storage batteries. These loads are divided into essential loads and secondary loads. The proposed control unit has double access points.
