Research on the Whole Model Splicing Problem of the Provincial and Regional Power Grid Based on Dispatching and Control Cloud

Abstract

With the increasing expansion of power grid scale and the increasing complexity of power grid structure, the integration of power network is becoming more and more obvious. The existing real-time model of power network can no longer meet the requirements of network analysis and calculation. In order to improve the accuracy of online analysis and application function of power grid, a whole model splicing method of the provincial and regional power grid is proposed, and the modeling method of boundary equipment, boundary splicing method and processing of boundary T connection lines are studied. By applying the whole model splicing scheme on Tianjin Power Grid, and validating the result, the method can improve the accuracy and rationality of the result for whole model splicing of the provincial and regional power grid, at the same time meet the requirements of various network analysis and calculation.
