Description

Digital Twin-based Renewable Energy-linked Flow Battery Distributed Power System and Method

[0001] The present invention relates to a digital twin-based renewable energy-linked flow battery distributed power system and a method thereof, which involves constructing a digital twin data-based bidirectional distributed power system and developing an artificial intelligence-based integrated management system to improve the efficiency of renewable energy supply and power usage.

[0002] Generally, power supply systems are designed to supply electricity generated at power plants to loads on the consumer side through transmission lines. However, among the loads on the consumer side, particularly critical loads where power outages must not occur (e.g., electric furnaces in steel mills), a structure may be established to receive self-generated power (distributed power system) in parallel with the commercial power supplied from power plants (commercial power system).

[0003] In this case, the commercial power system and the distributed power system are typically connected under normal conditions through a grid connection device equipped with the structure of a circuit breaker, and are disconnected in emergencies (in the event of a commercial power failure). Such distributed power systems may include synchronous generators such as diesel generators and micro gas turbines, as well as solar power, wind power, fuel cell power, and small-scale combined heat and power generation; recently, there has been extensive research on economically viable distributed power sources.

[0004] To explain the power supply system described above in more detail, commercial AC power generated from a commercial power source such as a power plant and transmitted via a transmission line is applied to a commercial receiving bus via a circuit breaker, and multiple general consumer-side loads are connected to the commercial receiving bus. A self-generating bus is connected to the commercial receiving bus via a grid connection device, and a self-generating power source is connected to this self-generating bus via a circuit breaker, along with a self-generating side load.

[0005] The power supply system configured as described above has a structure in which the circuit breaker connecting the self-generating power source to the self-generating busbar is normally closed, so that commercial AC power is supplied to both the general consumer load and the self-generating load.

[0006] However, if an accident such as a ground fault or short circuit occurs in a transmission line or a commercial power receiving bus to which commercial AC power is applied, a circuit breaker that mediates the supply of the commercial AC power to the commercial power receiving bus by means of a separate protection relay is opened so that overcurrent does not flow to the load, and the system connection device is opened in sequence so that the commercial power system and the distributed power system are separated.

[0007] However, as described above, the operating time of the grid connection device that separates the commercial power system and the distributed power system is approximately 100 to 200 msec. Since the turn-off time is long, a voltage drop phenomenon occurs in the distributed power system due to the instantaneous voltage drop generated in the commercial power system, and problems such as the self-generating side load going down and operation stopping may occur.

[0008] Meanwhile, although most energy is currently obtained from fossil fuels, the use of fossil fuels has serious adverse effects on the environment, such as air pollution, acid rain, and global warming, and also has the problem of low energy efficiency.

[0009] In recent years, interest in renewable energy and fuel cells has rapidly increased to address the problems associated with the use of fossil fuels, and research and interest in this area are actively underway not only domestically but also globally.

[0010] Although the renewable energy market has entered a mature stage both domestically and internationally, the nature of renewable energy presents a problem in that the amount of generated energy fluctuates significantly depending on environmental factors such as time and weather. Therefore, there is a critical need for the widespread adoption of energy storage systems (redox flow batteries) to store generated renewable energy and stabilize its generation, and redox flow batteries are attracting attention as such large-capacity energy storage systems.

[0011] The Energy Management System, which operates the energy storage system linked to the solar power system, controls the charging of electrical energy produced from the solar power generation unit into the redox flow battery.

[0012] The power generated by the solar power system is input into a power converter into the AC grid, converted into DC power, and then charged into a redox flow battery. Starting at sunset, when solar power generation decreases, the charged redox flow battery discharges to transfer electrical energy to the outside as AC power.

[0013] Typically, to integrate redox flow batteries into a solar power system, redox flow battery modules are installed to sufficiently accommodate the system's output. However, since redox flow batteries have a limited output, multiple modules must be connected in parallel with the solar system to accommodate the rapidly fluctuating solar output caused by weather conditions.

[0014] Therefore, to accommodate the rapidly changing solar output depending on weather conditions, all installed redox flow cell modules must maintain a standby state.

[0015] However, if all redox flow batteries remain in a constant standby state, they consume more on-site power than necessary. Furthermore, if the total solar power generation is less than the sum of the rated outputs of all redox flow battery modules, the solar output is distributed across all modules, resulting in operation at a lower output than the rated output and a decrease in the conversion efficiency of the power converter.

[0016] Vanadium redox flow batteries have the characteristic that they must be operated by starting the internal pump of the module during charging and discharging to ensure that the flow of the electrolyte is not interrupted. However, in order to keep all installed vanadium redox flow battery modules in a standby state, the internal power consumption of the pump circulating the electrolyte increases.

[0017] Ultimately, this affects the efficiency, a critical factor of redox flow batteries, resulting in a decrease in the expected discharge amount relative to solar power generation.
