Abstract

The invention belongs to the technical field of a distributed generation micro grid system and provides an RTDS (real time digital simulator) based stability simulation testing platform for a micro grid system. The micro grid system is a small power generation and distribution system integrating a distributed power supply as well as energy storage, load, monitoring and protecting devices, simulation models about wind power, photovoltaics, energy storage, power grid, load and the like are established on an RTDS real-time simulation platform, a micro grid system RTDS simulation platform is formed, a micro grid system-RTDS hardware-in-loop testing platform is formed on the basis of various IO interfaces of the RTDS real-time simulation platform and in combination of a micro grid actual controller, accordingly, whether system parameters of the micro grid system under the operating conditions of steady state and transient state meet the national standard of stable operation of a power distribution network is tested, and the boundary range of the stable operation of the micro grid system is verified.

Description

technical field [0001] The invention belongs to the technical field of a distributed power generation micro-grid system of a power system, and relates to a micro-grid system stability simulation test platform based on RTDS (Real Time Digital Simulator). Background technique [0002] Microgrid system 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. It is an autonomous system that can realize self-control, protection and management. The microgrid system is one of the important forms of distributed generation. The microgrid system can be operated in parallel with the large power grid through the distribution network to form a joint operation system of the large grid and the small power grid, and can also independently provide power demand for local loads. . [0003] With the vigorous promotion of smart grid, the microgrid system provides...
