Description

Technical Field

[0001] The embodiments disclosed herein generally relate to a fossil fuel combustion, steam-based power plant, and more specifically to systems and methods for maintaining power continuity in a steam-based power plant. Background Technology

[0002] Many steam-based power plants generate electricity via steam turbines driven by steam produced from the combustion of fossil fuels (e.g., coal). Such steam-based power plants are typically connected to a power grid, such as a wide-area power distribution network that usually includes multiple power plants. Typically, coal-fired steam-based power plants use electricity from their connected power grid to drive various components, such as fuel feeders, fuel grinders, heaters, water pumps, air fans, etc., which facilitate the electricity generation operation.

[0003] However, many power grids often suffer from fluctuations in their ability to supply consistent power. For example, a grid may experience periods where demand exceeds supply due to natural events and / or accidents and / or human events and / or accidents. In such cases, the frequency of the power supplied by the grid can decrease by as much as 0.5 Hz or more. As will be understood, such fluctuations can damage various components within steam-based power plants and / or limit / impede normal power generation operations.

[0004] Therefore, there is a need for improved systems and methods for maintaining power continuity in steam-based power plants. Summary of the Invention

[0005] In one embodiment, a system for maintaining power continuity in a steam-based power plant is provided. The system includes a fossil fuel combustion power generation unit and an energy storage device. The fossil fuel combustion power generation unit is operable to generate electricity and supply it to the power grid. The energy storage device is electrically coupled to the fossil fuel combustion power generation unit and operable to: receive and store electricity from the fossil fuel combustion power generation unit during periods of excess power generation; and supply electricity to components of the fossil fuel combustion power generation unit during periods of power shortage in the power grid.

[0006] In another embodiment, a method for maintaining power continuity in a steam-based power plant is provided. The method includes receiving excess power from a fossil fuel combustion power generation unit electrically coupled to a power grid and the power storage device at a power storage device. The method also includes storing the excess power in the power storage device. Furthermore, the method includes supplying the stored excess power from the power storage device to components of the fossil fuel combustion power generation unit during periods of power shortage in the power grid.

[0007] In another embodiment, a non-transitory computer-readable medium storing instructions is provided. The stored instructions are adapted to a processor to: instruct a power storage device to receive excess power from a fossil fuel combustion power generation unit electrically coupled to a power grid and the power storage device; instruct the power storage device to store the excess power in the power storage device; and instruct the power storage device to provide the stored excess power to components of the fossil fuel combustion power generation unit during periods of power shortage in the power grid.

[0015] Furthermore, although the embodiments disclosed herein are described primarily with respect to steam-based power plants, it should be understood that the embodiments disclosed herein are applicable to other types of power plants and / or systems that rely on or benefit from uninterrupted and / or continuous electricity.

[0016] Now for reference Figure 1 This illustration shows a system 10 for maintaining electrical continuity in a steam-based power plant 12 according to an embodiment of the present disclosure. System 10 includes one or more fossil fuel combustion (e.g., coal-fired) power generation units 14, 16, and 18, and an electricity storage device / unit 20. In this embodiment, system 10 may also include a controller 22 having at least one processor 24 and a memory device 26. As will be explained in more detail below, the electricity storage unit 20 is operable to: receive and store electricity from one or more fossil fuel combustion power generation units 14, 16, and 18; and supply electricity to one or more components 28, 30, 32, 34, 36, 38, 39, 40, and / or 42 of the power generation units 14, 16, and 18 during periods of power shortage in the power grid 44 to which the power plant 12 is electrically connected.

[0017] like Figure 1As shown, each of the fossil fuel combustion power generation units 14, 16, and 18 may include a boiler 28, a steam turbine 30, a grinder 32, a classifier 34 (which may be incorporated into the grinder 32), a fan 36, a water pump 38, a heater 40, a plasma igniter 42 (located in the combustion chamber or fuel duct of the boiler or furnace, and typically requiring approximately 100kW-200kW), and / or other devices for generating steam and / or electricity. Furthermore, each of the fossil fuel combustion power generation units 14, 16, and 18 may additionally include an air pollution control system or environmental control system (ECS) 39 for gas purification (e.g., for removing NOx, SOx, Hg, particulate matter, etc.). Although Figure 1 A power plant 12 with three (3) fossil fuel combustion power generation units 14, 16 and 18 is depicted, but it should be understood that other embodiments may include a single fossil fuel combustion power generation unit, two (2) fossil fuel combustion power generation units and / or more than three (3) fossil fuel combustion power generation units.

[0018] An energy storage device 20, which may be located in power plant 12, is electrically connected to each of the fossil fuel combustion power generation units 14, 16, and 18. However, it should be understood that in other embodiments, the energy storage device 20 may be located outside power plant 12. In embodiments, the energy storage device 20 may be further connected to additional components, such as converters, inverters, transformers, pumps 46, conveyors 48, etc., which are separate from and / or shared with the fossil fuel combustion power generation units 14, 16, and 18. In embodiments, the energy storage device 20 may include one or more batteries 50 connected in parallel or series. The batteries 50 may be based on chemical acids and / or rare earth metals, such as lithium ions.

[0019] As will be understood, the power storage device 20 can be directly connected, i.e., without indirectly transmitting power through the power grid 44, to the steam turbine 30 (or its corresponding generator), so that the battery 50 can be directly charged via the power generated by the power plant 12. As will be further understood, in embodiments, the power storage device 20 can be connected to the power grid 44 and / or charged by the grid. In embodiments, the battery 50 can be electrically connected to the power generation units 14, 16, and 18 via power converters, transformers, and / or other conversion devices.

[0020] In an embodiment, system 10 may further include one or more sensors 52 operable to provide the controller 22 with sensory information about the power storage device 20. In an embodiment, the sensory information may include data about: the voltage level of battery 50; the discharge rate of battery 50; the charging rate of battery 50; the temperature of battery 50; the time period of battery 50 during charging and / or discharging; and / or other information about battery 50 and / or other components of the power storage device 20.

[0021] Go to Figure 2 The diagram illustrates a possible generalized scenario depicting the flow of electricity into and out of the energy storage device 20, i.e., the charging and discharging of the energy storage device 20. It can be seen that at t = 0, the charge (represented by line 54) is zero (0). The time period from t = 0 to t ≈ 9 to the left of the dashed line represents a situation where the power plant 12 and / or fossil fuel combustion power generation units 14, 16 and / or 18 generate more electricity than required by the grid 44, i.e., a period of low electricity demand and surplus electricity generation, where the surplus electricity is used to charge the energy storage device 20. The shaded area to the left of the dashed line indicates the energy storage of the energy storage device 20. The time period from t = 9 to t ≈ 24 represents a situation where the grid 44 cannot provide sufficient power flow to the fossil fuel combustion power generation units 14, 16 and / or 18, i.e., a period of high electricity demand and shortage experienced by the grid 44, and therefore, the energy storage device 20 discharges / provides previously stored electricity to the fossil fuel combustion power generation units 14, 16 and / or 18. The shaded area to the right of the dashed line indicates the energy release from the energy storage device 20. In other words, the energy storage device 20 replenishes or replaces the electricity previously supplied by the grid 44 to the fossil fuel combustion power generation units 14, 16 and / or 18, which in turn allows the fossil fuel combustion power generation units 14, 16 and / or 18 to continue operating in order to generate electricity for the grid 44, thereby maintaining the power continuity of the power plant 12 and / or the fossil fuel combustion power generation units 14, 16 and / or 18.

[0022] Figure 3The diagram illustrates another possible generalized scenario depicting the flow of electricity into and out of the power storage device 20 during a change in the maximum continuous rated output (“MCR”) of the power plant 12. As will be understood, the power storage device 20 can function as a charging (indicated as the area above the curve of line 54 relative to line 55) and / or discharging (indicated as the area below the curve of line 54 relative to line 55) of the power plant 12 and / or fossil fuel combustion power generation units 14, 16, and 18: operating at 50% MCR (generally indicated by arrow 56); ramping up (generally indicated by arrow 58); operating at 100% MCR (generally indicated by arrow 60); ramping down (generally indicated by arrow 62); and operating at 35% or lower MCR (generally indicated by arrow 64) (or even 25% or lower MCR).

[0023] Return to Figure 1 In some embodiments, the artificial intelligence application may be stored in memory device 26 and loaded into processor 24 for the purpose of monitoring the power flux into and out of power storage device 20. In some embodiments, the artificial intelligence application may include a neural network that receives input from one or more sensors 52. In some embodiments, the artificial intelligence application may provide management of power storage device 20, such as distributing available stored power to various power generation units 14, 16, 18 and / or components therein. In some embodiments, the artificial intelligence application may manage power storage device 20 to maximize the charging availability of power storage device 20 (i.e., storing electricity / energy). The artificial intelligence application may also monitor the status and / or performance of DC / AC and / or AC / DC conversion modules within power plant 12 and / or monitor and / or regulate the temperature of one or more components of power plant 12 and / or power generation units 14, 16, and 18. In some embodiments, the artificial intelligence application may include machine learning capabilities (e.g., may include a machine learning module).

[0024] As will be understood, the capacity and / or density of battery 50 are typically limited. Therefore, scheduling and / or real-time control of battery 50 operation can provide improved reliability of the power storage device 20. Thus, in one embodiment, an artificial intelligence application can provide lifetime monitoring of the power storage device 20, i.e., the AI ​​application can determine (or predict when) the power storage device 20 cannot effectively charge and / or discharge. In one embodiment, the AI ​​application can adjust the distribution of stored power from the power storage device 20 to the power generation units 14, 16, and 18 and / or components therein to compensate for load control, so as to smooth the load on each of the power generation units 14, 16, and 18. In one embodiment, the AI ​​application can provide or schedule predictive and / or preventative maintenance for battery 50. In one embodiment, the AI ​​application can provide recommendations for maintenance and / or component replacement of the power storage unit 20.

[0025] For example, in the implementation plan, the artificial intelligence application can employ dynamic optimization methods based on mathematical models, such as:

[0026] Maximizing profit (t) = Revenue from serving the grid (capacity revenue, spinning reserve, ...)

[0027] (SPS power generation cost + battery charging cost + battery discharging cost)

[0028] Received by:

[0029] a) Charging or discharging rate (battery density);

[0030] b) Capacity availability;

[0031] c) Steam power generation capacity;

[0032] d) Power consumption rate of steam-electric auxiliary equipment;

[0033] e) Minimum load of the steam power generation unit;

[0034] f) Limits from DC / AC and AC / DC conversion systems;

[0035] g) Limits derived from the start-up time of the steam power generation unit;

[0036] h) A process dynamic model (discretized in an appropriate manner); and / or

[0037] i) Other suitable constraints.

[0038] In implementations, the AI ​​application can be combined with advanced model-based estimation, detection, and / or control methods / subsystems that can provide enhanced flexibility compared to traditional power backup systems (e.g., gas generators). For example, in one implementation, the AI ​​application is operable to retrieve operational data and / or commands from conventional distributed control systems (“DCS”) and / or integrated control systems. In such implementations, the AI ​​application can utilize predefined analytics modules to process real-time (and / or historical) data to generate new operational guidelines and / or operational configurations. In another implementation, the AI ​​application can summarize the operational experience of power plant 12, such as successes and / or failures, and publish unstructured data, such as new knowledge gained from power storage devices 20 via neural networks, for use as source data by other AI systems, such as big data integrating “stacked benefits” in local and / or regional power grids.

[0039] Now go to Figure 4 In one implementation, the artificial intelligence application is operable to be electrically connected to at least one other processor 100, 102, 104 located outside the same power plant 12 in which the power storage device 20 is located. For example, the artificial intelligence application can electrically communicate via network 106 with a database and / or data center 106, another power plant 108, and / or another type of facility 112, which can handle, process, and / or otherwise benefit from data collected by sensor 52 and / or predictions made by the artificial intelligence application. In one implementation, the artificial intelligence application software is configured to support the operation of an integrated steam power generation system 10 with a battery energy storage system.
