General Mixed Norm Based Adaptive Control Algorithm for Distribution Static Compensator

摘要

This paper presents an implementation of distribution static compensator (DSTATCOM) using general mixed norm (GMN) based adaptive algorithm for the three-phase distribution system. By using the convex mixture oflpnorm andlqnorm as the cost function, the proposed general mixed norm based algorithm is effective for obtaining the corresponding active and reactive weights of load currents. The proposed algorithm is fast in convergence and has quick response. The performance of proposed control algorithm is observed under nonlinear load in simulation. The DSTATCOM using GMN algorithm is effective in achieving the functions such as reactive power compensation, harmonics elimination and load balancing under linear and nonlinear loads and the test results of Simulink are found satisfactory with harmonic distortion of the supply currents well meeting the power quality standards.
