Solar power generation system control technology

Can a stand-alone solar power generation system be controlled?

The proposed novel control strategy has been applied to the stand-alone solar power generation system and is physically illustrated in Figure 10. Initially, the standalone solar power generation system is constructed using a PV simulator (as detailed in Table 3) which is supervised by a computer.

Can a control strategy be used in a solar power generation system?

As the proposed novel control strategy design has been used for conventional solar power generation system hardware, the control strategy can suitably be expanded to larger stand-alone solar power generation systems. It can even be used in grid-connected and hybrid solar power generation systems.

How is PV power generation affecting control performance & stability?

PV power generation is developing fast in both centralized and distributed forms under the background of constructing a new power system with high penetration of renewable sources. However, the control performance and stability of the PV system is seriously affected by the interaction between PV internal control loops and the external power grid.

How can a PV generation regulation be implemented?

Similarly, a PV generation regulation can be implemented through a current control loop with a current reference proportional to limit power. This method is known as current limiting. Direct power control and current limiting methods operate independently of the MPPT methods. But, modified MPPT methods can also limit active power.

What is grid-integration of PV systems?

In general, the grid-integration of PV systems involves several components, as shown in Fig. 6, where the PV panels are the power sources, the power electronics converter is in charge of the power delivery to the grid (i.e., to realize the power conditioning), and the grid as the load has specific requirements that should be followed.

What are the control aspects of grid-connected solar PV systems?

Apart from this, the control aspects of grid-connected solar PV systems are categorized into two important segments, namely, a) DC-side control and b) AC-side control. This article covers the important features, utilization, and significant challenges of this controller and summarizes the advanced control techniques available in the literature.
