Solar Photovoltaic Power Generation Controller

Can solar PV plants participate in fr and voltage control?

This work presents a novel control method to allow solar PV plants to simultaneously participate in FR and voltage control. The active power loop of the PV plant maintains some active power reserves, and VSG-based control is utilised to up-and-down regulate the PV power in response to network disturbances.

What are the control requirements for a solar PV plant?

The typical control requirements are anything involving production, in terms of megawatts and mega-VARs, (active and reactive power). Optimally, a solar PV plant appears to the grid as a single, unified source of power. The goal is to maximize power output (and, therefore, revenue) while supporting a stable and reliable grid.

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.

What is intelligent control in PV system?

Intelligent control as a more advanced technology has been integrated into the PV system to improve system control performance and stability. However, intelligent control for the PV system is still in the early stages due to the extensive calculation and intricate implementation of intelligent algorithms.

What is a solar photovoltaic (PV) system?

Solar photovoltaic (PV) installations are the most prominent among the available RES, and solar PV units with capacities ranging from a few kilowatts to several hundred megawatts (MW) have been effectively integrated into the power network at both the transmission and distribution levels [ 3 ].

Can Utility-scale solar PV plants participate in frequency and voltage control?

In this paper, a detailed control and modelling framework for utility-scale solar PV plants to simultaneously participate in frequency and voltage control is presented.
