Abstract

The invention belongs to the technical field of micro grids, and discloses a micro grid small signal stability analysis and parameter coordinated setting system. The setting system comprises a distributed power generation module, an electrical energy transformation module, a power management module, a central control module, a wireless communication module, a grid parameter adjustment module, an abnormality alarm module and a power storage system. Through the grid parameter adjustment module, the parameters can be determined in a quick, accurate and coordinated manner, and the objective function and boundary conditions can be flexibly adjusted according to the stability requirements and the parameter constraints. The working time is greatly shortened, and the efficiency is improved. The micro grid small signal stability analysis and parameter coordinated setting system is simple in structure and more miniaturized, is suitable for family use, and is suitable for remote areas without grids.

Description

technical field [0001] The invention belongs to the technical field of micro-grids, and in particular relates to a micro-grid small-signal stability analysis and parameter coordination tuning system. Background technique [0002] Micro-grid (Micro-Grid), also translated as micro-grid, refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc. The proposal of microgrid aims to realize the flexible and efficient application of distributed power, and solve the problem of grid connection of distributed power with a large number and various forms. The development and extension of microgrids can fully promote the large-scale access of distributed power sources and renewable energy, and realize the highly reliable supply of various energy forms for loads. Smart grid transition. However, the existing microgrid parameter coordination is inaccurate...
