摘要
针对微电网中分布式发电的控制策略问题,利用Matlab/Simulink分别搭建了光伏电池、风力发电机、燃料电池及微型燃气轮机等分布式电源的模型,并在此基础上建立了包含上述分布式电源的低压微网系统仿真系统。在并网控制策略方面,光伏电池与风力发电机采用P/Q控制方式,燃料电池与微型燃气轮机采用下垂控制方式。通过仿真研究了该系统模型及控制策略在并网与孤岛模式下的动态特性。结果验证了该系统的可行性和有效性,为建立微网实验平台和示范工程奠定了基础。
Aiming at distributed generation control strategies in the micro-grid, use Matlab/Simulink to build the distributed generation models of the photovoltaic generation, the wind turbine, the fuel cell and the micro-turbine respectively, and then establish a low voltage micro-grid system involving the distributed generation above. On the respect of control strategy, the photovoltaic generation and the wind turbine is used P/Q control, and the fuel cell and the micro-turbine droop control. The dynamic characteristics of these system models and control strategies under the grid-connected and island mode were studied through the simulation. The results verify the feasibility and validity of this system,which is laid the foundation of the establishment of micro-grid experimental platform and demonstration project.
