Single-phase photovoltaic inverter control strategy

What are the current control strategies for single phase grid integrated photovoltaic inverters?

This paper has reviewed the current control strategies for single phase grid integrated photovoltaic inverters. From the above study, it can be concluded that the MPCC scheme shows best steady state performance as compared to other schemes. It also achieves effective harmonic mitigation in terms of reduced THD value of output current.

How to control a single phase inverter?

This control is based on the single phase inverter controlled by bipolar PWM Switching and lineal current control. The electrical scheme of the system is presented. The approach is widely explained. Simulations results of output voltage and current validate the impact of this method to determinate the appropriate control of the system.

What is a single phase voltage source inverter?

Solar is the fastest growing form of renewable energy and a single phase voltage source inverter is used to interface photovoltaic based plants with the distribution system. The grid integrated inverter has stringent control requirements.

What is a current controller in a photovoltaic inverter?

A current controller is employed to mitigate the harmonics in the current injected into the grid and regulate the power exchange between the plant and the grid. This paper presents a review of the current control strategies implemented for a single phase grid tied photovoltaic inverter.

What is a single phase inverter connected to the grid?

PV system connected to the grid Fig. 1 shows an electrical scheme of the single phase inverter connected to the grid , . The main specification of the inverter connected to the grid is that the current must be injected from a PV panel with a power factor within a certain range .

Which control strategies are used in a grid tied single phase VSI?

The significant control strategies namely current hysteresis control (CHC), proportional integral current control (PICC), proportional resonant current control (PRCC), dead beat current control (DBCC) and model predictive current control (MPCC) have been designed and analyzed for a grid tied single phase VSI.
