PV System Simulation with Boost Converter in MATLAB Simulink | Optimized Solar Power

Matlabhelpers demonstrate how to use the MATLAB software for simulation PV boost converter is a DC/DC power converter which steps up voltage from its input (source) to its output (load). In continuous conduction mode (current through the inductor never falls to zero), the theoretical transfer function of the boost converter is:

Single Phase to 3phase Inverter Control

The aim of the inverter is to export controllable power with the established voltage. The generated power is controlled by the in-phase current component which is proportional to the network power demand. The supervisory controller (SC), receiving power demand information from short-term/long-term prediction values, operates DG units either in a constant power output or in a load-following manner.

the power set-points generate a current reference for the current regulator. The closed-loop controller ensures that the output current tracks the reference value with a zero steady-state error.

Figure shows a block diagram of a grid-connected inverter control strategy, where the closed-loop current controller enables output power delivery by calculating an error signal from measured and commanded signals. The reference current is determined from the set values of the controller. Each inverter is responsible for controlling its output current and power according to a power demand set by the supervisory controller. The inverter power quality can be influenced by the background network harmonics. However, the quality can be improved by properly designing the controller and filter. Some of the desired features of the inner-loop current control are as follows: (1) accurate current control; (2) high bandwidth; fast dynamic response, 4–6 times faster than that of the outer voltage controller; (4) low current distortion, and filter resonance damping. These characteristics are achieved with the different control techniques for various microgrid model.
