Abstract

The invention relates to a micro grid experimental testing platform on the basis of an RTDS (Real Time Digital System), which comprises an RTDS simulation system, an interface screen cabinet and a micro grid control system, wherein the RTDS simulation system is connected with the micro grid control system by the interface screen cabinet; the RTDS simulation system is used for constructing a micro grid primary main loop and providing a real-time simulation environment; the interface screen cabinet is used for providing an actual engineering interface between the RTDS simulation system and the micro grid control system; and the micro grid control system is used for implementing energy management of an integral micro grid system. According to the invention, a simulation model of the micro grid primary main loop is established on the RTDS; a simulation time scale of the micro grid experimental testing platform is very close to that of an actual power system and can truly represent a state of the actual power system; parameters of the micro grid experimental testing platform are convenient and rapid to regulate; various operating working conditions of the integral micro grid system can be simulated at any time; and efficiency of micro grid experimental testing is greatly improved.

Description

technical field [0001] The invention relates to the field of micro-grid technology, in particular to an RTDS-based micro-grid test platform. Background technique [0002] In order to maximize the advantages of distributed power based on renewable energy and new energy in terms of economic benefits and environmental protection, countries around the world are vigorously advocating the development of micro-grid technology, and have begun to build unique micro-grid laboratories and demonstration projects. . In view of the diversity of the composition of the microgrid system and the flexibility of the operation mode, before the on-site joint commissioning of the microgrid project, in order to comprehensively assess the correctness and rationality of its control and protection functions and parameter configuration, it is usually necessary to take appropriate simulations. means to carry out relevant functional verification. Using the traditional physical simulation method to buil...
