Description

TECHNICAL FIELD

[0002] With the intensification of global climate change, the frequency of extreme disasters worldwide is increasing, which has caused great pressure on the safe and stable operation of the current power system and has caused a certain degree of economic loss. The line faults and line operation faults caused by extreme disasters cause some nodes to lose power supply, which in turn causes information nodes to fail, and the control center loses power regulation and control of the island nodes, which causes great hidden dangers to urban production and life. Moreover, due to the limitation of generator output adjustment, the power distribution network system may cause a larger range of cascading failures due to the inability to timely process the power flow changes caused by line faults.

This synergistic optimization can be realized through intelligent scheduling, energy management and market transaction, etc., aiming to maximize the utilization rate of the power system, reduce energy consumption and cost, and improve the reliability and sustainability of the power system. Synergistic optimization of source, load and storage is an important means of modern power system operation and management, which can effectively cope with the challenges of fluctuating load, renewable energy fluctuation, etc. in the power system, and realize the efficient operation of the power system.

[0029] Power supply node: refers to a node that can provide power to other nodes, usually a power plant, substation or distributed energy equipment. These nodes can transmit power to other nodes through transmission lines or distribution lines to ensure the normal operation of the power grid.

[0030] Information node: refers to a node that can obtain real-time operation information and control instructions of the power grid, usually a smart meter, monitoring device or remote monitoring system. These nodes are connected to the power grid management system through the communication network, which can monitor the operation state of the power grid in real time, diagnose faults and remotely control.

[0031] Island node: refers to the node that loses connection with the power grid due to power grid failure or other reasons and cannot operate normally. These nodes cannot obtain power from the power grid and cannot transmit power to the power grid, usually causing power failure in the local area. In the microgrid system, island nodes can be equipped with energy storage devices and intelligent control systems to realize isolated operation with the power grid and ensure local power demand.

[0032] According to the embodiment of the present application, a method embodiment of a configuration method of an energy equipment is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order from here.

[0035] Normal operation of the power grid line refers to that the line can stably transmit power and there is no failure or failure affecting the normal operation of the power grid. Non-normal operation includes problems such as line failure, short circuit, open circuit, etc., which cause the power grid to be unable to normally transmit power or have safety hazards. Non-normal operation may also include problems such as line overload, unstable voltage, frequent tripping, etc., which affect the stability and reliability of the power grid. In the case of non-normal operation, maintenance and processing need to be carried out in time to ensure the safety and normal operation of the power grid.

[0036] In the power grid, the energized node refers to the node in the power grid connecting various power equipment (such as generators, substations, transmission lines, etc.), and the energized node can be connected and disconnected by switches, circuit breakers and other control devices. The energized node is a key part of the power grid for transmitting power, and the energized node transmits power from the generator to various power units through the transmission line.

[0037] The information node refers to the node for monitoring, control and communication in the power grid. The information node obtains real-time data such as power grid operation state, fault information, load condition, etc. through sensors, monitoring devices, communication devices, etc. and transmits these information to the monitoring center or other relevant departments through the communication network. The information node can help the operator to discover the abnormal operation and failure of the power grid in time and make timely processing and scheduling.

[0038] ​For example, assuming that there is a power generator, a substation, several power transmission lines and multiple power consumption units in a power grid of a certain area, the power generator, the substation, the power transmission lines and the like can be regarded as power supply nodes, and the power supply nodes deliver power to the power consumption units (power consumption units) through the power transmission lines. At the same time, monitoring devices, communication devices and the like can be regarded as information nodes, and the information nodes can monitor the operation state of the power grid in real time and transmit relevant data to a monitoring center so as to be monitored and controlled by operating personnel.

[0039] According to some optional embodiments of the present application, the first load of each power supply node in the power grid under normal operation of the power grid line is determined, including the following steps: determining the air conditioner load of each power supply node; determining the water heater load of each power supply node.

[0040] The air conditioner load of each power supply node is determined by the following steps:

[0041] According to the actual refrigeration space volume of the air conditioner, the standard refrigeration space volume, the indoor temperature at time t and the air conditioner set temperature, the working state of the air conditioner at time t is determined; according to the working state of the air conditioner at time t and the working state at time t-1, the working state switching variable of the air conditioner is determined; according to the rated power and the starting power loss of the air conditioner, the working state at time t and the working state switching variable, the power consumption of the air conditioner at time t is determined. It can be expressed by the following formula:

[0042]

[0043]

[0044]

[0045]

[0046]

[0047] wherein, is the working state of the air conditioner at time t, is 1 when the air conditioner is in operation, is 0 when the air conditioner is in non-operation (standby) state, is the indoor temperature at time t, is the air conditioner set temperature at time t, V i S is the actual refrigeration space volume of the air conditioner, V i NFor the air conditioner standard refrigeration space volume, δ is the air conditioner standard refrigeration space temperature error. The air conditioner actual refrigeration space volume refers to the space volume that can be effectively refrigerated by the air conditioner in actual use, which is usually determined by the refrigeration capacity of the air conditioner and environmental conditions. The standard refrigeration space volume refers to the space volume that can be effectively refrigerated by the air conditioner under standard test conditions, which is generally a value obtained by testing under conditions such as indoor temperature and humidity that meet specific standards. This value can be used as a reference when purchasing an air conditioner, but the actual refrigeration effect will also be affected by factors such as environmental conditions and room structure. The air conditioner standard refrigeration space temperature error refers to the deviation between the actual indoor temperature and the set target temperature when the air conditioner is in refrigeration mode. This error usually occurs during air conditioner refrigeration, and the air conditioner standard refrigeration space temperature error depends on factors such as the performance, design, and use environment of the air conditioner. The standard refrigeration space temperature error is usually specified in detail in the technical specifications of the air conditioner product. For the air conditioner working state switching variable, when the air conditioner switches from standby state to running state at time t, is 1, is 0, at this time is 1; when the air conditioner switches from running state to standby state or the running state does not change at time t, is 0 or -1, at this time takes 0. i AC For the rated power of the air conditioner, P i ACh For the air conditioner startup power loss, For the power consumption of the air conditioner at time t.

[0048] Determining the water heater load of each powered node can be achieved by the following method:

[0049] According to the set water temperature of the water heater and the water temperature floating limit, the water temperature of the water heater at time t, the working state of the water heater at time t is determined; according to the working state of the water heater at time t and the working state at time t-1, the working state switching variable of the water heater is determined; according to the rated power of the water heater and the startup power loss, the working state of the water heater at time t and the working state switching variable, the power consumption of the water heater at time t is determined. Specifically, it can be expressed by the following formula:

[0050]

[0051]

[0052]

[0053]

[0054]

[0055] wherein, is the working state of the water heater at time t, T i RS is the set water temperature of the water heater, and ΔT is the water temperature fluctuation limit, is the water temperature of the water heater at time t, is the water heater working state switching variable, when the water heater switches from standby state to running state at time t, is 1, is 0, at this time is 1; when the water heater switches from running state to standby state or the running state does not change at time t, is 0 or -1, at this time is 0. P i R is the rated power of the water heater, P i Rh is the start-up power loss of the water heater, is the power consumption of the water heater at time t.

[0056] The water temperature fluctuation limit of the water heater refers to the fluctuation range of the water temperature during the working process of the water heater. This limit is usually set by the manufacturer according to product performance and safety standards, and is described in detail in the product manual. Generally speaking, the water temperature fluctuation limit of the water heater is between 38℃ and 50℃, in order to ensure that users will not be scalded when using hot water, and to meet the daily hot water demand. Water temperature fluctuation beyond this range may cause user injury or equipment failure, so manufacturers will strictly control the water temperature fluctuation limit of the water heater.

[0057] In step S104, in the case of abnormal operation of the power grid line, the configuration state of the energy equipment corresponding to the island node in all energized nodes is determined, wherein the energy equipment at least includes: energy storage equipment and distributed power supply equipment.

Standby state: the device is in standby state, i.e. as a standby device, generally started when the main device fails or shuts down.

[0059] For example, the energy device at least comprises: an energy storage device and a distributed power supply device, wherein the distributed power supply device is, for example, a gas turbine.

[0062] Specifically, the air conditioner of the island node is controlled to operate when the indoor temperature is lower than the upper limit of the first set temperature, which can be achieved by the following constraint (formula):

[0063]

[0064]

[0065] The water heater of the island node is controlled to operate when the water temperature is lower than the lower limit of the second set temperature, which can be achieved by the following constraint:

[0075] In addition, in the case of abnormal operation of the grid line, the control of the energy consuming unit and the energy storage device corresponding to the non-island node in all energized nodes can be realized by the following methods: controlling the air conditioner of the non-island node to operate when the indoor temperature is higher than the lower limit of the third set temperature; controlling the water heater of the non-island node to operate when the water temperature is higher than the upper limit of the fourth set temperature; controlling the energy storage device corresponding to the non-island node to be in the charging state, and controlling the energy storage device corresponding to the island node to keep maximum power charging; and controlling the distributed power supply device corresponding to the non-island node to keep minimum power output.

[0076] Specifically, the control of the air conditioner of the non-island node to operate when the indoor temperature is higher than the lower limit of the third set temperature can be realized by the following constraint (formula):

[0077]

[0078]

[0079] The control of the water heater of the non-island node to operate when the water temperature is higher than the upper limit of the fourth set temperature can be realized by the following constraint:

[0080]

[0081]

[0082] The control of the energy storage device corresponding to the non-island node to be in the charging state, and the control of the energy storage device corresponding to the island node to keep maximum power charging, so as to absorb the power flow overload caused by the line break as much as possible, can be realized by the following constraint:

[0083]

[0084]

[0085]

[0087] In the above formula, for indicating whether there is a broken line for the back-end line connected with the generator node of the node i, 0 if there is a broken line, otherwise 1, is the maximum charging power of the energy storage device corresponding to the node i, is the charging power of the energy storage device corresponding to the node i at time t.

[0088] The distributed power supply device corresponding to the non-island node is controlled to maintain the minimum power output, so that the non-island node can accommodate the power flow overload caused by the line break as much as possible, which can be realized through the following constraint:

[0089]

[0090]

[0091] wherein, is the minimum active power output of the distributed power supply device.

[0092] In step S106, according to the configuration state, the second load of each island node under the abnormal operation condition of the grid line is determined.

[0093] In some optional embodiments of the present application, according to the configuration state, the second load of each island node under the abnormal operation condition of the grid line is determined, including the following steps:

[0095] It is assumed that under the abnormal operation condition of the grid line, there are n island nodes, wherein the second load of the i-th (i∈n) island node can be determined by the following formula:

[0096]

[0099] As some optional embodiments of the present application, the running state of a specific information node i in the power grid can be determined by the following formula:

[0100]

[0101]

[0102] wherein x i,t is the running state of the information node, x i,t is 1, indicating that the information node is in normal operation, and at this time the actual load of the information node is equal to the normal operation load of the information node; x i,t is 0, indicating that the information node is in abnormal operation (failure), and at this time the actual load of the information node is less than the normal operation load of the information node.

[0103] Through the above method, the running state of all information nodes in the power grid is determined, and further, the target number of information nodes in normal operation under the condition of abnormal operation of the power grid line is determined according to the running state of all information nodes.

[0104] In step S110, the resilience evaluation index of the power grid is determined according to the first load, the second load and the target number, and the configuration state of the energy equipment corresponding to each energized node is controlled according to the resilience evaluation index.

[0105] The resilience of the power grid refers to the ability of the power system to maintain stable operation and rapid recovery in the face of various internal and external disturbances and failures. The resilience of the power grid includes the requirements for the reliability, recoverability and adaptability of the power system. Generally speaking, the resilience of the power grid refers to the ability of the power system to maintain the reliability and stability of power supply in the face of sudden events or abnormal conditions, to quickly isolate and recover from failures, and to adapt to new environmental and technical requirements. Improving the resilience of the power grid can enhance the anti-interference and response capabilities of the power system, and ensure the safe and stable operation of the power grid. The resilience evaluation index is used to evaluate the resilience of the power grid.

[0106] Preferably, the resilience evaluation index of the power grid is determined according to the first load, the second load, and the target number, and the configuration state of the energy equipment corresponding to each energized node is controlled according to the resilience evaluation index, for example, whether to configure the energy equipment corresponding to each energized node, wherein configuring the energy equipment corresponding to the energized node refers to setting and adjusting a specific energized node or power equipment to meet specific energy requirements and requirements. This includes adjusting the parameters, working mode, operation time, control strategy, etc. of the equipment to achieve efficient operation and energy utilization of the energy equipment. Configuring the energy equipment can be done through software control, remote monitoring, or manual operation. By configuring the energy equipment corresponding to the energized node, intelligent management and optimized control of the energy equipment can be achieved, improving energy utilization efficiency and reducing energy consumption costs. Exemplarily, the configuration state of the energy equipment usually includes the following: 1. Running state: the device is running normally and can provide the required energy output; 2. Standby state: the device is in standby mode and temporarily does not provide energy output, but can quickly recover to running state; 3. Off state: the device is completely off and cannot provide any energy output; 4. Fault state: the device has failed or has a failure warning and needs to be repaired or overhauled; 5.
