Description

technical field [0001] The invention relates to the field of power systems, in particular to a microgrid simulation system. Background technique [0002] In the R&D and functional testing stages of the micro-grid system device, it is necessary to simulate the on-site conditions for closed-loop tests to adjust and verify the control strategy and dynamic performance of the device. The common method of closed-loop test is to reduce the primary system equipment of the microgrid system according to a certain capacity ratio, build a small-capacity dynamic simulation experiment system according to the actual topology, and connect the interface equipment with the actual control equipment to form a closed-loop system. Complete various dynamic tests. The microgrid system involves many devices and is large in size. If the dynamic model test is carried out according to the above experimental method, it will not only occupy a large space, but also be expensive and uneconomical. Using pu...
