A nonlinear control algorithm of Li-ion battery substation for DC distributed system

Abstract : This paper presents a control algorithm for dc-bus stabilization in weak network that uses a Li-ion battery as the battery substation. The battery modules connected with 2-quadrant 4-phase parallel converter with interleaved technique. In this paper, a nonlinear control algorithm based on the flatness properties of the system is proposed. Using the flatness property, we propose simple solutions to dc distributed system and stabilization problems. A hardware system is implemented in laboratory. The prototype small-scale power plant is composed of a dc main source (80 V, 500 W), and a Li-ion battery module (11.6 Ah, 24 V). Experimental results substantiate the excellent control scheme during load cycles.
