Abstract

Renewable energy systems (RESs) have grown to be a more economical and eco-friendly option for isolated applications such as ship where the grid's energy cannot be delivered. However, the presence of RESs has a significant challenge since the generation mainly depends on meteorological conditions. Moreover, the ship applications contain pulsed load which cause high power pulsation, voltage drop, and instability in the overall system. This paper proposes a robust hybrid energy storage system (HESS) with an effective energy management. Besides, extracting the maximum generated power and regulating both the DC-bus and AC-bus voltages under different conditions such as changing the load demand, and different unsteady meteorological conditions. The HESS consists of battery energy storage system (BESS) and superconducting magnetic energy storage (SMES). The HESS is able to improve the stability of the DC-bus during the pulse load rather than the BESS only and SMES only. The performance of the proposed system with its control strategies are verified by test results.

基于mppt的船舶脉冲负载混合BESS-SMES风力发电系统直流母线电压控制

可再生能源系统(RESs)已经发展成为一种更经济、更环保的选择，适用于像船舶这样的孤立应用，在这些应用中，电网的能源无法输送。然而，RESs的存在面临着重大挑战，因为它的产生主要取决于气象条件。此外，船舶应用中含有脉冲负载，会引起大功率脉动、电压下降和系统整体不稳定。提出了一种具有有效能量管理功能的鲁棒混合储能系统。提取最大发电量，在负荷需求变化、不同非稳态气象条件下对直流母线和交流母线电压进行调节。HESS由电池储能系统(BESS)和超导磁储能系统(SMES)组成。HESS能够提高直流母线在脉冲负载期间的稳定性，而不仅仅是BESS和SMES。实验结果验证了所提系统及其控制策略的性能。
