Description

[Technical Field]

[0001] The present invention relates to the technical field of new energy stations, and more particularly to a hot standby loss compensation method, device and equipment applicable to wind power generation, solar power generation and energy storage power plants. [Background technology]

[0002] Toward the goal of "double carbon," new energy generation capacity is rapidly increasing, and large amounts of new energy are being connected to the grid. Their variability, randomness, and intermittency pose major challenges to the safe and stable operation of the grid. Therefore, allocating a certain proportion of new energy to energy storage is currently the solution to grid absorption and stable operation. As large amounts of energy storage enter the grid, how to maximize its effectiveness has become a hot research topic. One use of energy storage at this stage is as a time-space transfer medium for electrical energy to improve the absorption and utilization of new energy. Another use is to suppress fluctuations in wind and solar power generation and improve the quality of grid-connected electrical energy from new energy stations. A third use is to directly integrate grid scheduling, supplementing grid electricity shortages during peak consumption periods and achieving peak power supply.

[0003] Currently, when a wind power, solar power, and energy storage integrated power plant discards electricity as a whole, it still needs to be powered off from the grid, which is used to maintain the power generation equipment in a hot standby state, and the energy storage of the wind power, solar power, and energy storage itself cannot be used to compensate for the hot standby loss of the power generation equipment, which results in the energy storage of the wind power, solar power, and energy storage being idle, increasing the power purchasing costs of the wind power, solar power, and energy storage integrated power plant. Therefore, a method is needed to use the energy storage of wind power, solar power, and energy storage to compensate for power loss when the new energy stand is in a hot standby state. Summary of the Invention [Problem to be solved by the invention]

[0004] In view of this, the present invention provides a hot standby loss compensation method, device and equipment applicable to wind power generation, solar power generation and energy storage power plants, and solves the problem that power loss cannot be compensated for using energy storage from wind power generation, solar power generation and energy storage in the hot standby state of new energy stands.

[0023] In order to clarify the objectives, technical solutions and advantages of the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments that a person skilled in the art can obtain without making creative efforts belong to the protection scope of the present invention.

[0024] According to an embodiment of the present invention, there is provided an embodiment of a hot standby loss compensation method applied to wind power, solar power, and energy storage power plants, wherein the steps illustrated in the flowcharts of the drawings may be performed in a computer system as a set of computer-executable instructions, and although a logical order is shown in the flowcharts, in some cases the steps illustrated or described may be performed in an order different from that shown here.

[0025] In this embodiment, a hot standby loss compensation method applicable to a wind power generation, solar power generation and energy storage power plant is provided, which can be used in a wind power generation, solar power generation and energy storage power plant. FIG. 1 is a flowchart of the hot standby loss compensation method applicable to a wind power generation, solar power generation and energy storage power plant according to an embodiment of the present invention. As shown in FIG. 1, the process includes the following steps:

[0026] Step S101: obtain the active power value, active power direction vector and scheduling command power value of the grid connection point of the wind power generation, photovoltaic power generation and energy storage power plant;

[0027] Specifically, a wind power, solar power, and energy storage integrated power plant (abbreviated as wind power, solar power, and energy storage plant) includes a wind power, solar power, and energy storage coordination controller. The wind power, solar power, and energy storage plant is connected to a grid scheduling center, and the wind power, solar power, and energy storage coordination controller distributes power generation tasks based on scheduling commands sent from the grid scheduling center. A grid connection point is the connection point through which the wind power, solar power, and energy storage plant accesses the upper grid or other power systems. As shown in Figure 4, the grid connection point energy collection module can obtain the active power value and active power direction vector of the grid connection point of the wind power, solar power, and energy storage plant and receive the scheduling command power value sent from the grid scheduling center.

[0028] Step S102: Determine whether the scheduling command power value is equal to a preset threshold value.

[0029] Specifically, a preset threshold can be set to 0 to determine whether the scheduling command power value is equal to 0. If the scheduling command power value is equal to 0, it indicates that the grid scheduling center has not issued a scheduling command for wind power generation, solar power generation, and energy storage power plants to distribute power, and that the wind power generation, solar power generation, and energy storage power plants do not need to transport electricity to the grid. The control target is that the active power scheduling value of the grid connection point is 0, and power balancing is performed within the wind power generation, solar power generation, and energy storage power plants.

[0030] Step S103: When the scheduling command power value is equal to the preset threshold value and the active power direction vector of the grid connection point of the wind power generation, photovoltaic power generation, and energy storage power plant flows from the grid connection point to the wind power generation, photovoltaic power generation, and energy storage power plant, the active power value of the grid connection point is set as the active power scheduling value to be compensated.

[0031] Specifically, the control target is that the active power scheduling value of the grid connection point is 0, and when the scheduling command power value is equal to 0 and the active power direction vector of the grid connection point of the wind power generation, solar power generation, and energy storage power plant flows from the grid connection point to the wind power generation, solar power generation, and energy storage power plant, the active power value of the grid connection point is the active power scheduling value to be compensated.

[0032] Step S104: Power is distributed to the wind power generation, photovoltaic power generation and energy storage power plants based on the active power scheduling value.

[0033] Specifically, when the wind power generation, solar power generation, and energy storage coordination controller receives the active power scheduling value, the wind power generation, solar power generation, and energy storage coordination controller performs power distribution based on the active power scheduling value, so that the power generation equipment in the wind power generation, solar power generation, and energy storage power plant generates power based on the active power scheduling value.

[0034] The hot standby loss compensation method applied to wind power generation, solar power generation, and energy storage power plants according to this embodiment determines whether a scheduling command power value is equal to a preset threshold, sets the grid connection point scheduling command power value equal to the preset threshold as a control target, and distributes power to the wind power generation, solar power generation, and energy storage power plants using the active power when the active power direction vector of the grid connection point flows from the grid connection point to the wind power generation, solar power generation, and energy storage power plant as the active power scheduling value. This eliminates the defect of loss caused by grid power on / off during the hot standby period of power generation equipment when the wind power generation, solar power generation, and energy storage power plant is in a power generation limit state, thereby solving the problem of not being able to compensate for power loss using energy storage of wind power generation, solar power generation, and energy storage when the new energy stand is in a hot standby state. This solves the problem of balancing the hot standby electricity amount of wind power generation, solar power generation, and energy storage power plants on-site when the conventional wind power generation, solar power generation, and energy storage power plants are in a power generation limit state at zero power, and also achieves the purpose of reducing the operating costs and improving the efficiency of wind power generation, solar power generation, and energy storage power plants.

[0035] In this embodiment, a hot standby loss compensation method applicable to a wind power generation, photovoltaic power generation and energy storage power plant is provided, which can be used in a wind power generation, photovoltaic power generation and energy storage power plant. FIG. 2 is a flowchart of the hot standby loss compensation method applicable to a wind power generation, photovoltaic power generation and energy storage power plant according to an embodiment of the present invention. As shown in FIG. 2, the process includes the following steps:

[0036] Step S201: obtain the active power value, active power direction vector, and scheduling command power value of the grid connection point of the wind power generation, solar power generation, and energy storage power plant. For details, refer to step S101 in the embodiment shown in Figure 1, and the description will be omitted here.

[0037] Step S202: Determine whether the scheduling command power value is equal to a preset threshold value, for details, see step S102 in the embodiment shown in FIG.

[0038] In step S203, when the scheduling command power value is equal to the preset threshold value and the active power direction vector of the grid connection point of the wind power generation, photovoltaic power generation, and energy storage power plant flows from the grid connection point to the wind power generation, photovoltaic power generation, and energy storage power plant, the active power value of the grid connection point is set as the active power scheduling value to be compensated.

[0039] Specifically, step S203 is as follows: The method includes a step of setting the active power value of the grid connection point as the active power scheduling value to be compensated when the scheduling command power value is equal to a predetermined threshold value and the active power direction vector of the grid connection point of the wind power generation, solar power generation, and energy storage power plant flows from the grid connection point to the wind power generation, solar power generation, and energy storage power plant within a predetermined time period.

[0040] Specifically, the preset time can be set according to the actual situation and is not particularly limited here. For example, the preset time is set to t (t=20) s, and when the scheduling command power value is equal to 0 and the active power direction vector of the grid connection point of the wind power generation, solar power generation, and energy storage power plant flows from the grid connection point to the wind power generation, solar power generation, and energy storage power plant and does not change within the preset time (e.g., 20 s), the acquired active power value of the grid connection point is the active power scheduling value to be compensated.

[0041] In the hot standby loss compensation method applied to the wind power generation, solar power generation, and energy storage power plants according to this embodiment, when the scheduling command power value is equal to a predetermined threshold value and the active power direction vector of the grid connection point of the wind power generation, solar power generation, and energy storage power plant flows from the grid connection point to the wind power generation, solar power generation, and energy storage power plant within a predetermined time, the active power value of the grid connection point is taken as the active power scheduling value to be compensated, and the predetermined time is maintained, thereby ensuring the reliability of the determination that the scheduling command power value is equal to the predetermined threshold value and the active power direction vector of the grid connection point of the wind power generation, solar power generation, and energy storage power plant flows from the grid connection point to the wind power generation, solar power generation, and energy storage power plant, and providing a reliable basis for subsequent power allocation to the wind power generation, solar power generation, and energy storage power plants based on the active power scheduling value.

[0042] Step S204: Distribute power to the wind power generation, photovoltaic power generation and energy storage power plants based on the active power scheduling value.

[0043] Specifically, wind-solar-energy-storage power plants include solar power plants, wind power plants and energy storage plants.

[0044] The above step S204 includes the following steps.

[0045] In step S2041, the maximum power generation capacity of the photovoltaic power plant, the maximum power generation capacity of the wind power plant, and the remaining capacity of the energy storage plant are obtained.

[0046] Specifically, the maximum power generation capacity of a solar power plant refers to the amount of power generated by the solar power plant within a unit time at a certain installed capacity, and in this embodiment, the maximum power generation capacity of a solar power plant refers to the amount of power generated by the solar power plant in one day. The maximum power generation capacity of a wind power plant refers to the amount of power generated by the wind power plant within a unit time at a certain capacity. In this embodiment, the maximum power generation capacity of a wind power plant refers to the amount of power generated by the wind power plant in one day. The remaining capacity of an energy storage power plant refers to the percentage of the available electrical energy in the battery of the energy storage power plant that accounts for the nominal capacity.

[0047] Step S2042: Based on the maximum power generation capacity of the photovoltaic power plant, the maximum power generation capacity of the wind power plant, the remaining capacity of the energy storage power plant, and the active power scheduling value, power is distributed to the photovoltaic power plant, the wind power plant, and the energy storage power plant according to a preset order.

[0048] In one alternative embodiment, step S2042 above is The method includes a step of allocating power in accordance with the allocation order of the photovoltaic power plant, the wind power plant, and the energy storage power plant based on the maximum power generation capacity of the photovoltaic power plant, the maximum power generation capacity of the wind power plant, the remaining capacity of the energy storage power plant, and the active power scheduling value.

[0049] Specifically, based on the maximum power generation capacity of the photovoltaic power plant, the maximum power generation capacity of the wind power plant, the remaining capacity of the energy storage plant, and the active power scheduling value, the wind power generation, photovoltaic power generation, and energy storage coordination controller in the wind power generation, photovoltaic power generation, and energy storage plant sequentially distributes power according to the distribution order of the photovoltaic power plant, the wind power generation plant, and the energy storage plant.

[0050] The hot standby loss compensation method applied to wind power generation, photovoltaic power generation and energy storage power plants in this embodiment distributes power in accordance with the distribution order of the photovoltaic power plant, wind power generation plant and energy storage power plant based on the maximum power generation capacity of the photovoltaic power plant, the maximum power generation capacity of the wind power plant, the remaining capacity of the energy storage power plant and the active power scheduling value, and distributes power in accordance with the priority of the photovoltaic power plant, wind power generation plant and energy storage power plant, thereby achieving the purpose of distributing power according to the characteristics of variability, randomness and intermittency of power generation, so that the power demand in the wind power generation, photovoltaic power generation and energy storage power plant is balanced within the power plant.

[0051] In an alternative embodiment, as shown in FIG. 4 , the solar power plant includes a solar energy management platform and a solar power inverter, the wind power plant includes a wind power plant energy management platform and a wind power generation unit, and the energy storage power plant includes an energy storage coordination controller and an energy storage unit.

[0052] The step of distributing power in accordance with the distribution order of the photovoltaic power plant, the wind power plant, and the energy storage power plant in sequence based on the maximum power generation capacity of the photovoltaic power plant, the maximum power generation capacity of the wind power plant, the remaining capacity of the energy storage power plant, and the active power scheduling value includes the following steps:

[0053] Step a1: Send an active power scheduling value to a solar energy management platform, and make a solar power inverter execute the active power scheduling value based on the maximum power generation capacity of the solar power plant.

[0054] Specifically, as shown in Figure 4, the wind power generation, solar power generation, and energy storage coordination controller sends an active power scheduling value to the solar energy management platform, and after the solar energy management platform receives the active power scheduling value distributed by the wind power generation, solar power generation, and energy storage coordination controller, it transmits it to the solar power generation inverter and executes the active power scheduling value by controlling the solar power generation inverter to generate power based on the maximum possible power generation of the solar power plant. During execution, the solar energy management platform feeds back the maximum possible power generation of the solar power generation inverter during power generation to the wind power generation, solar power generation, and energy storage coordination controller in real time.

[0055] Step a2: send a remaining active power scheduling value after the power of the photovoltaic power station is distributed to the wind power generator energy management platform, and make the wind power generation unit execute the remaining active power scheduling value after the power of the photovoltaic power station is distributed based on the maximum power generation capacity of the wind power generator station.

[0056] Specifically, as shown in Figure 4, the wind power generator energy management platform receives the remaining active power scheduling value after the power of the photovoltaic power plant is distributed, sent from the wind power generation, photovoltaic power generation, and energy storage coordination controller, transmits the remaining active power scheduling value after the power of the photovoltaic power plant is distributed to the wind power generation unit, which generates power and thereby executes the remaining active power scheduling value after the power of the photovoltaic power plant is distributed. During execution, the wind power generator energy management platform feeds back the maximum possible power generation amount of the wind power generation unit currently generating power to the wind power generation, photovoltaic power generation, and energy storage coordination controller in real time.

[0057] Step a3: send the remaining active power scheduling value after the power of the photovoltaic power station is distributed and after the power of the wind power station is distributed to the energy storage coordination controller, and make the energy storage unit execute the remaining active power scheduling value after the power of the photovoltaic power station is distributed and after the power of the wind power station is distributed based on the remaining capacity of the energy storage power station.

[0058] Specifically, as shown in Figure 4, the energy storage coordination controller receives the remaining active power scheduling values ​​after the power of the photovoltaic power plant is distributed and after the power of the wind power plant is distributed, which are sent from the wind power generation-photovoltaic power generation-energy storage coordination controller, and transmits the remaining active power scheduling values ​​after the power of the photovoltaic power plant is distributed and after the power of the wind power plant is distributed to the energy storage unit, so that the remaining amount of the energy storage unit compensates for the remaining active power scheduling values ​​after the power of the photovoltaic power plant is distributed and after the power of the wind power plant is distributed. During execution, the energy storage coordination controller feeds back the remaining amount of the energy storage unit during power generation to the wind power generation-photovoltaic power generation-energy storage coordination controller in real time.

[0059] Furthermore, if the amount of electricity that a photovoltaic power plant can generate is equal to or greater than the active power scheduling value allocated by the wind power generation, photovoltaic power generation, and energy storage coordination controller, it does not need to be distributed to the wind power plant and the energy storage plant.If both the photovoltaic power plant and the wind power plant are unable to generate electricity, the remaining capacity of the energy storage plant will implement the active power scheduling value allocated by the wind power generation, photovoltaic power generation, and energy storage coordination controller, ensuring normal power consumption of the power generation equipment during the hot standby period.

[0060] In an optional embodiment, as shown in FIG. 4 , the step of distributing power to the solar power plant, the wind power plant, and the energy storage power plant according to a preset order based on the maximum power generation capacity of the solar power plant, the maximum power generation capacity of the wind power plant, the remaining capacity of the energy storage power plant, and the active power scheduling value includes: When the solar power generation inverter executes the active power scheduling value based on the maximum power generation capacity of the solar power plant and the wind power generation unit executes the remaining active power scheduling value after the power of the solar power plant is distributed based on the maximum power generation capacity of the wind power plant, the method further includes a step of using an energy storage unit in accordance with the remaining capacity of the energy storage plant to suppress power variability of the solar power generation inverter and the wind power generation unit.

[0061] Specifically, when photovoltaic power plants and wind power plants generate power, they are easily affected by weather conditions, which makes it easy for power generation instability to occur, i.e., power generation fluctuations, randomness, and intermittency occur. In order to compensate for the power generation fluctuations, randomness, and intermittency that occur when photovoltaic power plants and wind power plants generate power, when the photovoltaic power inverter executes the active power scheduling value and the wind power unit executes the remaining active power scheduling value after the photovoltaic power plant's power is distributed, an energy storage power plant needs to be used in conjunction with the photovoltaic power plant and the wind power plant to suppress the power fluctuations, randomness, and intermittency of the photovoltaic power inverter and the wind power unit.

[0062] The hot standby loss compensation method applied to the wind power generation, photovoltaic power generation and energy storage power plant according to this embodiment sequentially makes the photovoltaic power generation inverter execute an active power scheduling value based on the maximum power generation capacity of the photovoltaic power plant, makes the wind power generation unit execute an active power scheduling value remaining after the power of the photovoltaic power plant is distributed based on the maximum power generation capacity of the wind power generation plant, and makes the energy storage unit execute an active power scheduling value remaining after the power of the photovoltaic power plant is distributed and after the power of the wind power generation plant is distributed based on the remaining capacity of the energy storage power plant, thereby ensuring continuous power supply to the electrical equipment during the hot standby period, realizing the purpose that the wind power generation, photovoltaic power generation and energy storage power plant supplies power according to electricity demand using photovoltaic power generation, wind power generation and energy storage, and achieving power supply balance within the wind power generation, photovoltaic power generation and energy storage power plant, so that the power generation equipment is able to operate in the hot standby period. There is no need to power on and off the grid during standby periods, saving costs and improving the operating efficiency of wind power, photovoltaic power and energy storage power plants. The photovoltaic inverter executes an active power scheduling value based on the maximum power generation capacity of the photovoltaic power plant, and the wind power unit executes the remaining active power scheduling value after the photovoltaic power plant's power is distributed based on the maximum power generation capacity of the wind power plant. The energy storage unit is used in conjunction with the photovoltaic inverter and the wind power unit based on the remaining capacity of the energy storage plant, so that when power fluctuations occur when the photovoltaic power plant and the wind power plant are generating electricity, the energy storage plant can supplement the power fluctuation value. This allows the energy storage plant to suppress the fluctuation, randomness and intermittency of the photovoltaic power plant and the wind power plant, ensure that the power supply to the equipment is not interrupted during hot standby periods, and improve the reliability of the power supply.

[0063] In this embodiment, a hot standby loss compensation method applicable to a wind power generation, solar power generation and energy storage power plant is provided, which can be used in a wind power generation, solar power generation and energy storage power plant. FIG. 3 is a flowchart of the hot standby loss compensation method applicable to a wind power generation, solar power generation and energy storage power plant according to an embodiment of the present invention. As shown in FIG. 3 , the process includes the following steps:

[0064] Step S301: obtain the active power value, active power direction vector, and scheduling command power value of the grid connection point of the wind power generation, photovoltaic power generation, and energy storage power plant. For details, refer to step S201 in the embodiment shown in Figure 2, and the description here will be omitted.

[0065] Step S302: Determine whether the scheduling command power value is equal to a preset threshold value, for details, see step S202 in the embodiment shown in Figure 2, and the description here will be omitted.

[0066] In step S303, when the scheduling command power value is equal to the preset threshold value and the active power direction vector of the grid connection point of the wind power generation, photovoltaic power generation, and energy storage power plant flows from the grid connection point to the wind power generation, photovoltaic power generation, and energy storage power plant, the active power value of the grid connection point is set as the active power scheduling value to be compensated. For details, please refer to step S203 in the embodiment shown in Figure 2, and the description will be omitted here.

[0067] Step S304: Power is distributed to the wind power generation, photovoltaic power generation and energy storage power plants based on the active power scheduling value. For details, please refer to step S204 in the embodiment shown in Figure 2, and the description will be omitted here.

[0068] Step S305: if the scheduling command power value is not equal to the preset threshold, power is distributed to the wind power generation, photovoltaic power generation and energy storage power plants according to the scheduling command power value.

[0069] Specifically, the preset threshold is equal to 0. If the scheduling command power value is not equal to 0, the scheduling command power value issued from the grid scheduling center is sent to the wind power generation, photovoltaic power generation, and energy storage coordination controller, and the wind power generation, photovoltaic power generation, and energy storage coordination controller receives the scheduling command power value issued from the grid scheduling center and respectively issues the scheduling command power value to the photovoltaic power generation inverter, the wind power generation unit, and / or the energy storage coordination controller, thereby causing the photovoltaic power generation inverter, the wind power generation unit, and / or the energy storage unit to execute the scheduling command power value.

[0070] The hot standby loss compensation method applied to wind power generation, solar power generation and energy storage power plants in this embodiment allocates power to the wind power generation, solar power generation and energy storage power plants based on the scheduling command power value when the scheduling command power value is not equal to the preset threshold, thereby achieving the purpose of returning to normal command allocation mode when the scheduling command power value is not equal to the preset threshold, improving the flexibility of dispatching based on the scheduling command power value, and maximizing the utilization of the wind power generation, solar power generation and energy storage power plants.
