Active Current Control Method Based on Grid-Connected Proton Exchange Membrane Fuel Cell

摘要

摘要: 负载功率变化时，由于传统PQ控制方法未充分考虑质子交换膜燃料电池（PEMFC）发电系统的实际运行特性，不能有效响应负载需求. 为了使PEMFC发电系统在负载变化时准确、快速响应，根据PEMFC发电系统的运行特性和PEMFC并网PQ控制原理，建立了包含150 kW PEMFC电堆、DC/DC变换器、并网逆变器、滤波器等的PEMFC并网系统模型，并在此基础上，提出了基于PQ控制的主动电流控制方法.MATLAB仿真测试结果表明，该方法在额定和非额定输出功率条件下，均能够根据PEMFC输出特性使并网系统有效地响应负载变化，实现从电源到并网的大闭环控制，保证并网系统的稳定、可靠运行，且网侧电流谐波分别为1.76%和2.89%，满足并网要求.

Abstract: The conventional PQ control method fails to effectively respond to load demands because it does not adequately consider the actual operating characteristics of the proton exchange membrane fuel cell (PEMFC) system when the power load changes. In order to ensure that the PEMFC operation system responds accurately and quickly, a model of a PEMFC grid system consisting of a 150 kW PEMFC stack, DC/DC converter, inverter, and filter is developed according to the operation characteristics and PQ control principle of the PEMFC. Then, a PQ control-based active current control method is proposed based on this model. The results of a MATLAB simulation indicate that the proposed active current control method can fulfill the demands of grid connection under both rated and non-rated output power conditions, enabling the grid-connected system to effectively respond to load changes. This actualizes large closed-loop control from the power supply to the interconnection and ensures stability and reliability in the grid system operation with bus current harmonics of 1.76% and 2.89%, whereas the traditional PQ control method can only operate stably when the PEMFC outputs at the rated power (150 kW).
