Abstract

The invention discloses a micro-grid integration testing simulation platform based on an RTDS and a method and belongs to digital simulation. An RTDS digital simulator, a real control system and a micro-grid energy management system are arranged, electric loops of a micro-grid are erected in an RSCAD, and the structure of the micro-grid can be flexibly changed as required. Through the micro-grid integration testing simulation platform based on the RTDS, a micro-grid coordination control strategy and an energy management algorithm are effectively verified, and the new effective method for testing a micro-grid control algorithm and a running strategy is provided. Besides, the method is simple and convenient to operate and well solves the problems that according to an existing air and diesel storage micro-grid simulation method, a testing platform is a real device based on scale reduction, extension of the micro-grid structure is not facilitated, and the erected platform does not has universality.

Description

technical field [0001] The invention belongs to the field of power system real-time digital simulation test and micro-grid technology, and in particular relates to an RTDS-based micro-grid integrated test simulation platform and method. Background technique [0002] The power supply reliability of the microgrid requires the configuration of traditional diesel generators in the microgrid. In addition, in order to suppress the fluctuation of the output power of renewable energy such as photovoltaics and wind turbines, it is often necessary to configure a certain capacity of energy storage to form a wind / solar power grid. Diesel storage type independent microgrid. As the main form of power supply in remote areas and islands, this kind of microgrid is of great significance to the local economic development and the basic living guarantee of residents. [0003] At present, the research on wind diesel storage microgrid mainly focuses on the optimal capacity configuration of each c...
