example 1

[0039] The fossil energy is oil, the energy converter 2 is an internal combustion engine, the bidirectional power electronic converter 5 is connected to the battery pack of the rooftop photovoltaic power generation system, and the mechanical load 3 is a refrigeration compressor. There are the following operating modes:

[0040] (1) When the power generation of the photovoltaic cell group is sufficient and cooling is required, the electric energy of the photovoltaic cell group is input to the winding of the inner rotor 12 through the bidirectional power electronic converter 5, and is converted into mechanical energy to drive the mechanical load 3 through electromagnetic coupling Compressor, at this time, the energy flows from the photovoltaic power generation system to the refrigeration compressor.

[0041] (2) If the cooling capacity is small at this time, the excess electric energy of the photovoltaic cell group can be coupled to the winding of the stator 11 through electroma...

example 2

[0046] The fossil energy is natural gas, the energy converter 2 is a gas turbine, and the mechanical load 3 is a water pump / turbine of a pumped storage power station. There are the following operating modes:

[0047] (1) When the public power grid is at a low load, the electric energy on the public power grid is transformed by the bidirectional power electronic converter 4 and delivered to the winding on the stator 11, and then the outer rotor 13 is driven by electromagnetic coupling to drive the water pump to transfer the water to the reservoir. The water is pumped to the upper reservoir for energy storage, at which time the energy is converted from electrical energy to potential energy of water.

[0048] (2) When the load of the public grid is at a peak, the water discharge drives the turbine to drive the outer rotor 13 to rotate to generate electricity, and the power is transmitted to the grid through the bidirectional power electronic converter 4. At this time, the energy ...

[0052] In the desert area, the fossil energy is gas, the energy converter 2 is a gas turbine, and the load 3 is a turbine of a sand pumping storage power station. There are the following operating modes:

[0053] (1) When the power load is at a low point, it means that the power delivered by the power plant is greater than the demand of downstream users. The external rotor can be driven by the power of the public grid, and the transmission belt will transfer the downstream sand to a high-lying place for energy storage. At this time, the energy Convert electrical energy into potential energy of sand.

[0054] (2) When the load of the public grid is at a peak, the turbine driven by sand release drives the outer rotor 13 to rotate to generate electricity and transmit power to the public grid. At this time, the energy flows from the sand to the grid.

[0055] (3) When there is no sun, the photovoltaic battery pack installed under the solar panels has insufficient electric energy,...

Description

technical field [0001] The invention relates to the fields of energy and electrical engineering, in particular to a multi-energy energy interconnection router and a control method thereof. Background technique [0002] As we all know, in the information Internet, a router is a key device to realize information distribution, which can realize two-way flow of information and connect different users. In recent years, "Energy Internet" has gradually become the focus of attention. In 2015, my country's government work report proposed for the first time that an "Internet +" action plan will be formulated, and the release of a new round of electricity reform plan has aroused people's expectations for energy Internet. my country's preliminary plan is to realize energy interconnection by 2050 in order to promote the widespread use of green and renewable energy and improve the efficiency of comprehensive energy utilization. There are many types of energy commonly used at present, su...
