Energy storage system integrated into 161KV power system

What is dynamic regulation in battery energy storage system?

2.2. Dynamic Regulation Dynamic regulation is a bidirectional frequency control strategy. The battery energy storage system actively adjusts its output power within 1 s based on the grid frequency state, instantaneously compensating for active power to achieve grid frequency stability.

Why should energy conversion and storage devices be integrated?

The combination system of these two kinds of devices can make up for the defects of each other and make them offer better performance as power supply devices. Therefore, more attention has been paid to the integrated system of energy conversion and storage devices.

How can a battery energy storage system support changes in power system structure?

Therefore, the application technology of the battery energy storage system is used to support the impact of changes in the new power system structure. This paper designed control technologies based on the WECC second-generation generic model, namely, dynamic regulation, steady regulation, and virtual inertia regulation.

How a battery energy storage system can be derived from auxiliary services?

Battery energy storage systems can be derived from many auxiliary services according to different control strategies, such as frequency regulation reserve, peak shaving and valley filling, smoothing of solar output power, load dispatch, islanding operation, reactive power compensation, and virtual inertia provision.

What is a battery energy storage system model?

The battery energy storage system model consists of the renewable energy plant control (REPC_A) model, the renewable energy electrical control (REEC_C) model, and the renewable energy generator/converter control (REGC_A) model. Figure 3. The block diagram of the battery energy storage system [ 26 ].

Why is energy storage important for large-scale re integration?

Energy storage significantly facilitates large-scale RE integration by supporting peak load demand and peak shaving, improving voltage stability and power quality. Hence, large-scale energy storage systems will need to decouple supply and demand.
