Abstract

The invention belongs to the technical field of micro-grids, and particularly relates to a test micro-grid construction and control method capable of being used for verifying various micro-grid structures. The test type micro-grid comprises a double-bus structure and a segmented control structure, and can simulate and verify various micro-grid structures, including the test type micro-grid formedby adopting the double-bus structure and segmented control on a 10kv voltage circuit. And the problems of singleness and limitation of a single bus structure of a traditional 10kv voltage line are solved. The structure of the test-type microgrid can be adjusted for different demonstration engineering projects so as to carry out simulation verification, and an optimal operation scheme is found outby using a two-layer operation optimization method with an economic index as a bottom layer and an electric energy quality index as an upper layer, so that the test-type microgrid always operates in an optimal working state, and the system operation is more reasonable.

Description

technical field

[0001] The invention belongs to the technical field of micro-grids, and in particular relates to a test micro-grid construction and control method that can be used for various micro-grid structure verifications. Background technique

[0002] With the increasing use of new energy sources, the micro-grid composed of distributed power sources is becoming more and more diverse, and various micro-grid structures are derived. Although the microgrid structure is diverse, the traditional microgrid structure has the disadvantage of singleness. Different areas such as remote mountainous areas, island areas, and urban industrial and commercial parks need to adopt a fixed microgrid structure. This has great obstacles to the construction of microgrids. The capacity of micro-sources and loads in each micro-grid structure is fixed according to the actual demonstration project, so there may not be distributed power sources and loads with specified capacities during the plat...
