Abstract

The invention relates to a parallel real-time simulation method for a photovoltaic power generation system. The grid connection of power electronic parts of the photovoltaic power generation system are generally performed through a filter containing an inductor and a capacitor, by utilizing the topological feature and the principle that inductive currents and capacitor voltage cannot change suddenly in tens of microseconds, the photovoltaic power generation system is partitioned by taking the filter inductor and the filter capacitor as a boundary, the interface modes of a controlled voltage source and a controlled current source are designed, a power electronic simulation part and an alternating-current network simulation part are built independently, a few microseconds of real-time simulation is performed on the power electronic simulation part on an FPGA, and tens of microseconds of real-time simulation is performed on the alternating-current network simulation part on a CPU. Compared with the prior art, the parallel real-time simulation method for the photovoltaic power generation system has the advantages that the power electronic simulation part and the alternating-current network simulation part are built independently, the topological structure of the system and the electronic feature of elements are fully used to achieve system partition, and joint simulation of different step sizes can be performed on the two simulation parts.

Description

technical field [0001] The invention relates to the technical field of power system simulation, in particular to a parallel real-time simulation method for a photovoltaic power generation system. Background technique [0002] Due to people's concern for environmental protection and sustainable development, solar energy, as a clean and inexhaustible energy source, has received more and more attention. Photovoltaic power generation is a main form of solar power generation. The photovoltaic power generation system generally includes photovoltaic cells, power electronic conversion circuits (DC-DC conversion circuits, DC-AC inverter circuits), LC filters, AC grids and other parts. The work of the photovoltaic power generation system depends on the controller's precise control of power electronic conversion circuits such as DC-DC conversion circuits and DC-AC inverter circuits to achieve normal operation functions such as maximum power tracking and grid-connected power generation;...
