摘　　要：在由多输入接口组成的微型电网系统中,提出了一种智能化的能量管理策略。该策略在简单的操作基础上,可以实现多个子模块之间的自动的功率分配以及启动停止的控制,并将各个子模块的状态显示在触摸屏上供使用者实时观察整个系统运行状态。同时提供了各个子模块单独的操作接口,便于单个模块现场的调试以及检修。当各个子模块组合完成后,一键切换到能量自管理状态,系统进入自动运行状态。单个模块故障后,能量管理系统可自动将对应的模块退出运行,并根据现有工作状态正常的模块自动更新新的控制策略。各个子系统中的子模块都可以互相作为备用设备来使用,比如发电子系统中,风、光、油、氢可以互相作为补充和备用设备。制氢子系统中余电制氢和重整制氢可互为补充。储能子系统中电池和氢气互为补充。发电子系统中柴油发电机和DCAC逆变器互为补充。这样在正常运行状态中,通过合理的策略使系统运行在最优的效率点。在异常运行状态中,可以通过切换子模块的方式使整个系统稳定运行,提高了系统的鲁棒性。同时,这整个微网系统还可以作为更高等级的电网系统的子系统来使用,比如由多个微网系统组网可形成更大功率、更灵活的电网系统。An intelligent energy management strategy is proposed in a micro-grid system composed of multiple input interfaces.Based on simple operation,this strategy can realize automatic power distribution and start and stop control among multiple submodules,and display the status of each submodule on the touch screen for users to observe the running status of the whole system in real time.At the same time,it provides a separate operation interface for each sub-module,which is convenient for the field debugging and maintenance of a single module.After the combination of each sub-module is completed,the system switches to the state of energy self-management with one key and enters the state of automatic operation.When a single module is faulty,the energy management system automatically takes the corresponding module out of operation and automatically updates the new control policy based on the existing normal module.Submodules in each subsystem can be used as backup devices for each other.For example,in the power generation subsystem,wind,light,oil,and hydrogen can be used as supplementary and backup devices for each other.In hydrogen production subsystem,residual hydrogen production and reforming hydrogen production can complement each other.Batteries and hydrogen complement each other in the energy storage subsystem.The diesel generator and DC AC inverter complement each other in the power generation subsystem.In this way,the system can run at the optimal efficiency point through reasonable strategies in the normal running state.In the abnormal running state,the whole system can run stably by switching submodules,which improves the robustness of the system.At the same time,the whole micro-grid system can also be used as a subsystem of a higher level power grid system,for example,the network of multiple micro-grid systems can form a more powerful and flexible power grid system.
