Research and Application of Simulation Test Method for Precision Load Control System

Abstract

Precision load control is an important part of UHV AC-DC grid system protection, and it can also be used as a precise switching device for distributed energy, micro-grid and other systems. Through the classification, grading and sub-regional management of load resources, the real-time precise control of the interrupted load of the classified users can be realized by the direct dispatching of the dispatching, which can avoid a large number of overall pull-off of the substation or the line, and reduce the social impact of the grid fault. At the lowest level, improve the defense capability of large power grids. In order to ensure the stability and reliability of the precision load control system, the Precision load control system needs to be fully verified before it is put into use. In this paper, a set of simulation test environment is developed for the characteristics of precise load control system devices and complex test systems. The test environment is based on the actual software and hardware architecture, for internal communication characteristics, research test methods, customized test case drivers, and simulation. Various operating conditions under full load operation, comprehensive verification and assessment of the functional performance of the precision load control system to ensure the stability and reliability of the precision load control system. The proposed simulation test method has certain reference significance for the simulation test of precise load control system and new energy safety and stability control system.
