Description

technical field [0001] The invention relates to the field of simulation testing, in particular to a simulation optimization method for operating parameters of a grid-connected inverter. Background technique [0002] Power electronic systems are very complex, and have nonlinear and time-varying characteristics, so their design and analysis are difficult. Generally, some simulation tools are needed to assist product design in order to shorten the development cycle, reduce development costs and improve reliability. sex. As an important simulation form, semi-physical real-time simulation generally has two methods: "actual controller + virtual object" and "virtual controller + actual object", which are mainly used in the development process of power electronic system controller software. At present, in the process of developing power electronic systems using the RTLAB simulation platform, most of the RTLAB platform is used to load the main topology and electrical environment, an...

Problems solved by technology

[0004] 1. The existing photovoltaic grid-connected inverter in-the-loop simulation platform needs to manually change the parameters many times, perform half-in-the-loop simulations step by step, save and analyze data many times, and the whole process will consume a lot of time

[0005] 2. On the existing grid-connected standard test platform, the control strategy needs to be tested for active power control, reactive power control, fault ride-through control, operation adaptability, anti-islanding protection, etc. The test process is complicated and the test environment is changeable, requiring multiple tests Modifying the model and electrical parameters is also a time-consuming and inefficient process
