State Estimation and SCADA System Data Cooperation Problem Analysis

Abstract:

Steady-state measurement value is the calculation premise of state estimation. However, power grid operates more often under dynamic state in actual practice. Thus, applying measured data from SCADA in state estimation directly lead to the incorrect and inaccurate calculation result. Based on the premise of state estimation calculation, the online electrical measurements and sampling methods are analyzed, and the deviation between real electrical values and sampling data is calculated. The cooperation problem between SCADA data and state estimation is proved using MATLAB/Simulink Software.
