Abstract

The present invention provides a low-cost semi-physical clock adaptive virtual microgrid experiment platform, including: (1) virtual microgrid model server (VMMS); (2) programmable microgrid central control based on a PC-based clock reference (PMGCCCRC); (3) The communication network connecting the virtual microgrid model server and the programmable microgrid central controller (PMGCCCRC) with controllable clock reference. The software system of the experimental platform includes the virtual microgrid model server program and the microgrid central controller software with controllable clock reference. The microgrid simulation model runs on the virtual microgrid model server (VMMS). And the control parameters are all from the microgrid simulation model. The invention has the advantages of ensuring the correctness and accuracy of the simulation, obtaining more authentic and credible simulation results, effectively shortening the development cycle of the microgrid, and greatly reducing the cost of the semi-physical simulation of the microgrid.

Description

technical field [0001] The invention relates to a semi-physical experimental platform for verifying control strategies such as coordinated control and energy management of the system in a micro-grid system based on a central controller, in particular to a low-cost semi-physical adaptive clock virtual micro-grid experimental platform. Background technique [0002] The microgrid is a small power grid composed of various micro sources, which can realize grid-connected operation or independent autonomous operation on the basis of fully meeting the user's requirements for power quality and power supply safety; into the main grid. The microgrid central controller (MGCC) is the control core of the whole system. Its basic function is to realize the data collection, scheduling and control of each device in the microgrid, and also to realize the start-up of the devices in the microgrid. The seamless switching between the microgrids, tracking the load of the microgrid, maintaining the...
