This technical report presents a simulation model of a hybrid energy converter in the MATLAB/Plecs software package. The simulation model of the hybrid converter includes a mains AC/DC converter, a DC intermediate circuit, a battery DC/DC converter and a photovoltaic DC/DC converter.
The mains AC/DC converter consists of a two-level PWM converter and an LCL filter, and the control-regulation structure of VOC management of the same is implemented in the simulation.
The battery DC/DC converter is a bidirectional step-down converter realized by means of two transistors and two reverse diodes, and a choke on the battery side.
Photovoltaic DC/DC converter is a step-up converter that is realized using one transistor, one diode and a choke on the side of photovoltaic modules.
Photovoltaic and battery modules were also modeled, and the parameters of available photovoltaic and battery modules, which are expected to be used in the realization of the hybrid converter prototype, were used. The same can be pointed out for other system components whose parameters were necessary when creating the simulation model.
The report contains the results of testing the simulation model in different stationary and dynamic modes of system operation.
