“…The main objective of quantization processing is to reduce the amount of data that needs to be transmitted over the network, which can reduce the communication delay, increase the reliability of the system and reduce the cost of the NCS [19]. The accuracy of the quantization process directly affects the control performance of the power converter [20]. Therefore, it is essential to design an appropriate quantization processing algorithm for the NCS of the power converters.…”

In this paper, a uniform quantization design method for the parallel DC-DC converter network control system (NCS) is proposed in combination with sliding mode control (SMC) strategy to solve the problem that the performance of the system is poor due to the inability to process long signals in time. Taking the parallel buck converter as an example, firstly, the master-slave current sharing SM controller of the parallel buck converter is designed. Then, the NCS containing the designed SM controller is uniformly quantized in the continuous domain, and the stability performance of the system is analyzed according to the quantization error. Considering the application of the parallel buck converter in the actual digital control system, the discretization effect of the uniform quantization SMC system is studied by using a zero-order hold (ZOH) and the stability conditions of the discrete quantization system are given. Finally, the state trajectories and output performances of the system under different parameters in the continuous domain and discrete domain are analyzed by simulations, and the correctness and reliability of the uniform quantization SMC system designed in this paper are further verified by experiments.INDEX TERMS parallel DC/DC converters, sliding mode control, network signal transmission, uniform quantizer, discretization effect.

In this paper, transient stability analysis of a detailed model multi-machine power system was carried out to focus on the impact of HVDC link on system stability by comparing the critical fault clearing times of two operational scenarios, namely an AC transmission system with and without parallel HVDC transmission. The advantage and performance of AC-DC transmission for the improvement of response to transient instability caused by phase to ground fault was researched by detail simulation carried out in MATLAB/SIMULINK.
