What is adaptive VSG Energy Storage Coordination?

In modern power systems with massive renewable energy connected to the grid, frequency stability is an important factor in maintaining the reliable operation. Based on this background, an adaptive VSG energy storage coordination control strategy was developed to enhance the adaptive regulation ability.

Does VSG technology improve the response efficiency of energy storage systems?

The unbalanced power also decreased from 0.466 kWh to 0.342 kWh. This indicates that the adaptive characteristics of VSG technology not only improve the response efficiency of energy storage systems to frequency changes, but also optimize the management of the state of charge.

What is the energy storage system model?

The model includes new energy generation, energy storage system, and VSG control module to simulate load fluctuations and their impact on frequency response. The initial state of charge of the energy storage system is set to 50%, taking into account the frequency changes and response characteristics under different operating conditions.

What are energy storage systems?

Energy storage systems (ESSs), and particularly battery energy storage systems, are finding their way into a very wide range of applications for utilities, commercial, industrial, military and residential power. Applications include renewable integration, frequency regulation, critical backup power, peak shaving, load leveling, and more.

What is VSG technology?

By utilizing advanced algorithms, real-time monitoring data can be transformed into accurate power grid models. VSG technology allows control systems to deeply understand the dynamic characteristics of power systems, and thus reproduce the true dynamic behavior of the power grid (Mcglone et al. 2023). Figure 1 displays the control structure.

What is adaptive VSG technology?

According to the dynamic performance of systems under different control strategies, the performance of adaptive VSG technology is quantified, providing theoretical and technical support for the frequency regulation mechanism. The unit parameters containing adaptive VSG and new energy power system are shown in Table 2.
