Under the “double carbon” goal, distributed generation (DG) with inverters will show an explosive growth trend. The microgrid can operate in different modes as a channel for DG to connect to the main grid. In t.
HOME / Simple model of microgrid inverter - CAPTURED ENERGY SOLAR (PTY) LTDChapter 2 Inverter Design A common power source in existing microgrids is a photovoltaic (PV) array, which must have its DC output sent through a power inverter in order to generate the appropriate AC waveforms to handle commercial appliances.
The hardware parameters of the inverter are shown in Table 1, and the control strategy is implemented in a DSP (TMS320F28335). An industrial computer (BECKHOFF CX5130) is used as the microgrid central controller (MGCC), and a programmable AC power supply (Chroma P61514) is used to simulate the grid voltage, and its maximum capacity is 36 kVA.
The recommended design practice is to use the same voltage control in the inverter control layer for both grid- connected and islanded modes, which ensures continuities in the state variables throughout the transition operation, thus achieving smooth transients during transition operation.
