This letter proposes a DC microgrid for sustainable power generation on the Mars/Moon for a human inhabitation base. The proposed microgrid includes: (i) A wind turbine (WT) system with a dual rotor generator (DRG) whose output is rectified using a passive rectification state and connected to the microgrid common DC bus with a fixed voltage using a DC-DC converter. (ii) Solar panels that use Passive Emitter and Rear Cell (PERC) material suitable for in-space application whose data are available to the authors; the solar panels are connected to the DC bus using a DC-DC converter. (iii) Battery energy storage system (BESS) that uses a modified lithium-ion material that is space-tested and connects to the DC bus via a bidirectional DC-DC converter. The microgrid feeds three loads, a constant DC load, a 3-phase AC load, and a Mars Rover charger station. A maximum power point tracking (MPPT) controller is proposed for the WT and solar system while a supervisory controller is developed that manages the power flow strategy from the sources to the loads based on the BESS state of charge (SoC). The letter discusses conditions of the Mars/Moon, the challenges for sustained power generation and provides simulation results for the steady-state and transients analyses.

月球和火星上基于微电网的风能和太阳能发电

这封信提出了一个直流微电网，用于在火星/月球上为人类居住基地可持续发电。拟议的微电网包括：(i) 具有双转子发电机 (DRG) 的风力涡轮机 (WT) 系统，其输出使用无源整流状态进行整流，并使用 DC-DC 转换器以固定电压连接到微​​电网公共直流母线. (ii) 使用适合空间应用的无源发射极和背面电池 (PERC) 材料的太阳能电池板，其数据可供作者使用；太阳能电池板使用 DC-DC 转换器连接到直流母线。(iii) 电池储能系统 (BESS)，使用经过空间测试的改性锂离子材料，并通过双向 DC-DC 转换器连接到 DC 总线。微电网为三个负载供电，一个恒定直流负载，一个三相交流负载，和一个火星探测器充电站。为 WT 和太阳能系统提出了最大功率点跟踪 (MPPT) 控制器，同时开发了一个基于 BESS 充电状态 (SoC) 管理从电源到负载的功率流策略的监控控制器。这封信讨论了火星/月球的条件、持续发电的挑战，并提供了稳态和瞬态分析的模拟结果。
