Problems solved by technology

[0002] For power supply in remote areas such as the wild and isolated islands, the use of conventional power grids will result in high grid construction costs and user electricity costs, and serious line losses will occur during long-distance power transmission; especially for flexible and changeable outdoor temporary In the power supply scenario, the conventional power grid not only has a long construction period, but also the disposal of the conventional power grid after the power supply is completed will cause a great waste of resources; in the conventional power supply mode, a power station with a certain power level can only supply a specific level of load, and the compatibility is poor. When the load When the number and types increase, it will be difficult to meet the load demand quickly and at low cost; in addition, most of the current mainstream micro-grid systems mainly use diesel power generation systems for power supply. Problems such as low rate are prominent

Embodiment 1

[0021] Embodiment 1: as figure 1 As shown, the present invention discloses a multi-energy complementary mobile microgrid system, which includes two microgrid subsystems that can work independently and be used in parallel, namely sub-microgrid A and sub-microgrid B; the microgrid The subsystem includes a power station module, a fuel cell module, a photovoltaic module, and an energy storage module, and adopts a modular design idea as a whole. After combining the four modules, the structure is a standard-sized container, which is flexible and can be set up according to the modular structure. In the civil construction house, the application scenarios are flexible and rich; the microgrid subsystem is highly scalable, and the connection between the communication bus and the AC bus can enable multiple microgrid units to realize mutual assistance, compatibility with loads of different power levels, and communication The bus communicates externally through the electro-optical converter...

Embodiment 2

[0023] Embodiment 2: as figure 2 As shown, the microgrid subsystem of the present invention includes an AC bus and a DC bus. The mains power is converted by the mains booster module and then converged to the DC bus. The output power of the photovoltaic module is converted by the photovoltaic booster module and then converged to the DC bus for energy storage. The output power of the battery is converted by the charging and discharging module 1 and then converged to the DC bus, and the output power of the fuel cell module is converted by the charging and discharging module 2 and then connected to the DC bus; the power on the DC bus is converted by the inverter module of the energy storage converter PCS Converged to the AC bus to supply the load, the power of the power station module is converted by the power station converter PCM and then converged to the AC bus to supply the load or reversely charge the energy storage battery of the energy storage module; when the mains system ...

Embodiment 3

[0024] Embodiment 3: as image 3As shown, the mobile microgrid system may not include a power station module. In order to extend the battery life of the system while taking into account the idea of ​​combining four parts into a standard container, the entire microgrid subsystem can be composed of photovoltaic modules, energy storage modules, and fuel cell modules according to 2: In addition, the entire system can also be configured by photovoltaic modules, energy storage modules, fuel cell modules, and fuel cell endurance modules in a ratio of 1:1:1:1, of which the fuel cell endurance module is mainly responsible for the fuel supply. Storage function, all the other are with embodiment 1.
