Detailed Description
The invention is described in further detail below with reference to the figures and specific examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention relates to a novel energy router system which combines a distributed power generation unit, an energy storage unit, a load, a sensor and an electric energy conversion unit. The system integrates not only power control but also a communication system. As shown in figure 1.
The energy router system comprises a large power grid system, a sensor module, a communication module, a control module, an alternating current load module, a direct current load module, a bidirectional AC/DC module, a bidirectional DC/DC module, a DC/DC module, an MPPT module, a storage battery module, a photovoltaic module and a fan module, wherein the large power grid system is respectively connected with the bidirectional AC/DC module and the alternating current load module; the branch of the fan module is connected in series with a DC/DC module and an MPPT module; the bidirectional DC/DC module, the storage battery module and the large power grid system are in communication connection with the sensor module; the bidirectional AC/DC module, the photovoltaic module and the fan module are in communication connection with the communication module and the control module.
Specifically, the energy router system may be decomposed into the following modules for detailed analysis.
1. Sensor module
The module comprises a light intensity sensor, a wind power sensor and a temperature sensor. The sensor module transmits the acquired data to the intelligent control module through a communication line.
The light intensity sensor is used for sensing light intensity, transmitting the obtained light intensity information to the intelligent control module through a communication line, and then judging the power emitted by the photovoltaic power generation module. The wind sensor is used for sensing the wind power, transmitting the measured wind power information to the intelligent control module, and further judging the power generation power of the fan. The temperature sensor can collate the collected temperature information so that the power demand of the load can be estimated from the side. The magnitude of the load power is strongly related to the temperature.
2. Intelligent bidirectional DC/DC module and energy storage unit
When the intelligent control module judges that the electric energy sent by the power generation unit is larger than the electric energy used by the load, the internal switch of the intelligent bidirectional DC/DC module is turned on through the intelligent communication network (as shown in the attached figure 2), so that the energy can be transmitted to the energy storage unit, when the energy storage of the storage battery module reaches a peak value, a signal is fed back to the intelligent control module, and the internal switch of the intelligent bidirectional DC/DC module is turned off. Meanwhile, other modules can be opened to transfer redundant energy into a large power grid.
When the electric energy generated by the power generation unit in the system is smaller than the electric energy used by the load, and the intelligent control module receives the information, the intelligent bidirectional DC/DC module is opened through the communication module, so that the stored electric energy is reversely transmitted to the system.
3. Intelligent bidirectional AC/DC module
The structure of the module is shown in FIG. 3, and can be divided into three working conditions of AC/DC, DC/AC and stop operation.
Under the AC/DC working condition, when the direct current load is overlarge, the alternating current in the alternating current power grid is converted into the direct current through the module and transmitted to the direct current load side, and the power supply safety of the direct current load is ensured.
And under the DC/AC working condition, when the grid-connected operation of the distributed power generation unit is considered, the generated direct current is converted into alternating current through the module and is transmitted to a large power grid system.
When a maintenance signal or a signal that the island needs to operate and equipment needs to be replaced is received, the switch can be disconnected, and the module stops working.
4. Distributed power generation unit
In fig. 1, only two distributed power generation units, namely a photovoltaic module and a fan module, are listed, and the system not only comprises the two units, but also comprises other distributed units, and the figure is only an example.
5. Intelligent control and intelligent communication module
As shown in the attached figure 1, the intelligent communication module receives communication information transmitted by each unit, transmits the information to the intelligent control module, and the intelligent control module analyzes the information and transmits an operation signal to each unit through the intelligent communication module and a communication line.
In conclusion, the invention provides a micro-grid system which can be operated independently and can be connected to the grid. The distributed power generation unit, the energy storage unit, the load and the sensor are integrated; the communication system also comprises an intelligent router with information transmission and information interaction functions; the intelligent electric energy conversion device can communicate and has a start-stop function; the control system of the intelligent router with the functions of environment monitoring, electric energy calculation and information storage.
