6 FAQs about [Principle of Photovoltaic System Power Control Board]
What is a PV control structure?
Then, PV systems are not only power generation systems but also active systems to optimize the grid performance. In general, control structures are hybrid systems that combine linear and non-linear techniques; as well as classical techniques, advanced control and artificial intelligence methods.
What are the main control objectives in PV systems?
The main control objectives in PV systems are maximum power and power quality. But, considering the growth of PV systems and other renewable energies connected to power grid, current grid codes are adapting new impositions to mandate that distributed energy resources have specific grid support functions.
What is a PV system?
In PV systems are integrated classic techniques of control theory, electrical power systems and power converters. The control structures that satisfy standards and grid codes allow to improve safety, quality, efficiency and stability in power system.
How to develop control laws for stable operation of PV systems?
The development and implementation of control laws for stable operation of PV systems has been possible thanks to the integration of different disciplines such as control theory, power electronics, electrical power systems, communications, embedded hardware, software and data processing.
How a PV system regulates the output power flexibly?
In such a case, the PV systems can regulate the output power flexibly without additional hardware devices. However, conventionally, the PV systems are controlled by an MPPT strategy to optimize the power generated from the PV arrays. With an MPPT, the PV systems are always seeking the MPP.
What is the P-V curve of a PV system with fppt control?
The P-V curve of a PV system with the FPPT control by limiting the output power is shown in Fig. 5. It can be seen from Fig. 5 that there are two power limiting points, i.e., at the left and the right sides of the MPP (FPP1 and FPP2).
