Novel approach to PV inverter modeling and simulation
Photovoltaic (PV) inverter manufacturers use custom, proprietary control approaches and topologies in their inverter design. The proprietary nature of these approaches makes it challenging
The simulation of the inverter component contains a mathematical implementation of the inverter and related control algorithms that covers maximum power extraction from the PV plant, grid synchronization and support (eg, reactive power injection), voltage control, active and reactive power provision control or fault ride through.
A PV simulator is a programmable DC power source that replicates the electrical behaviour of real photovoltaic panels. It generates I-V and P-V curves by adjusting parameters such as irradiance and temperature, allowing controlled, repeatable testing of PV inverters and related devices under realistic solar conditions.
A time synchronization filter was added to address the frequency mismatch between the actual sampling frequency and the solution step size. The results of numerical research indicate that the proposed digital twin model has the ability to accurately simulate the dynamic characteristics of photovoltaic grid connected inverters.
Using the example SolarCellPowerCurveExample, the optimal values have been determined as 342V DC and 20.05A AC for an irradiance of 1000W/m^2 and panel temperature of 20 degrees Celsius. Inverter efficiency is determined in two independent ways. The first compares the ratio of AC power out to DC power in over one AC cycle.
