An Improved Nonlinear Control Design of A Grid-Connected Battery Storage System Through A Bidirectional Vienna Converter
摘要
This paper presents a bidirectional Vienna converter for a grid-connected battery storage system, which allows for bidirectional power flow and provides several grid services, including voltage regulation and reactive power compensation. The proposed control strategy aims to manage the power flow between the grid and battery storage system, improving the stability and reliability of the grid. In normal conditions, the power flows from the power grid to the battery storage system, and in the presence of grid perturbations, the flow reverses. The performance of the proposed system is evaluated through simulations under Matlab Simulink, demonstrating its effectiveness in maintaining a stable grid connection and providing fast response times to grid fluctuations.
