On the one hand, the energy system needs to provide safer and more reliable power services for users under normal weather conditions; on the other hand, it also needs to overcome various disturbances during extreme weather events to ensure the continuity and stability of energy supply. Therefore, it is particularly urgent to develop new energy system planning methods and mobile resource scheduling schemes. By optimizing equipment capacity and realizing multi-energy complementarity using energy conversion equipment, the economy and sustainability of the energy system can be effectively improved. Especially during extreme weather or disasters, the flexible scheduling ability of mobile resources will become the key to meeting user needs and enhancing system resilience.

[0003] However, in the existing technical research on the optimization of the energy system configuration under extreme weather, the impact on renewable energy is often only considered, while the dynamic changes in the demand-side load and the collaborative scheduling potential of multiple types of mobile resources (such as emergency generators and in-vehicle energy storage) are ignored, resulting in insufficient system resilience and difficulty in effectively coping with the complex disturbances on both the supply and demand sides in disaster scenarios.

[0015] (III) Beneficial effects The beneficial effects of the present invention are as follows: First, by integrating multi-source extreme disaster event observation data, a dual-state resilience adaptive Markov process is used to dynamically simulate the device failure probability and line failure risk, and a dynamic incremental model of user cooling / heating / electricity load driven by meteorological parameters is coupled to construct a disaster response database. This database breaks through the limitations of the decoupling of meteorological data from device failure models and user load characteristics in traditional methods. This database not only covers multi-dimensional failure mechanisms on the device side, but also couples the time-varying incremental model of cooling / heating / electricity load driven by meteorological factors, breaking through the limitations of one-sided disaster risk assessment or static load prediction in traditional planning, and deeply exploring the impacts of extreme weather and natural disasters on the supply side and demand side.

[0016] On this basis, based on fuzzy chance constraints, the fluctuations in renewable energy output and user load ranges are converted into credibility fuzzy variables. Combining with the set of fault scenarios generated by the disaster response database, a capacity configuration optimization model with the goal of minimizing the levelized cost of electricity is constructed. Through multi-energy coupling constraints, embedding of equipment failure probabilities, and definition of fuzzy chance constraint boundaries, this model realizes the coordinated planning of the capacities of energy supply equipment, energy storage devices, and energy conversion equipment under extreme weather conditions. This method reduces the total system cost while ensuring the reliability of energy supply in scenarios with a high proportion of renewable energy penetration, and solves the problem of insufficient resilience optimization in existing planning caused by simplifying meteorological disaster risk factors into fixed thresholds. Through this comprehensive optimization, the adaptability and resilience of the system in the face of extreme climate conditions or natural disasters are significantly improved, and while pursuing system economy, the ability of the system to respond to sudden extreme events is enhanced.

[0017] Furthermore, on the basis of multi-energy complementary capacity optimization, three types of mobile resources, namely mobile emergency power vehicles, electric vehicles, and diesel generators, are innovatively introduced. Elasticity enhancement is achieved through the implementation of damaged road network topology reconstruction, spatio-temporal transfer chain modeling, and action state coordination mechanisms for mobile resources.

[0018] Thus, through the collaborative decision-making of device capacity optimization driven by the disaster response database and dynamic scheduling of mobile resources, the present invention realizes a dual elastic gain of strengthening the disaster resistance ability of fixed devices and rapid post-disaster response of mobile resources under extreme weather conditions, providing an innovative solution for the design and operation of highly resilient energy systems.

Detailed implementation manners

[0020] In order to better explain the present invention for easy understanding, the present invention will be described in detail below in conjunction with the accompanying drawings through specific implementation manners.

[0021] Prior to this, in order to facilitate the understanding of the technical solution provided by the present invention, the concept of the energy system will be introduced first below.

[0022] It should be clear that, as shown in Figure 1 The energy system in the embodiment of the present invention includes: an input end, a system end and a demand end; among them, the input end includes a power grid, solar energy, wind energy, geothermal energy and natural gas, and the energy conversion equipment (electrolyzer, photovoltaic panel, fan, ground source heat pump, gas turbine, electric chiller, fuel cell and waste heat boiler, etc.) in the system end is combined to realize the conversion between energies to meet the cooling, heating, power and hydrogen loads of each building at the demand end. At the same time, relying on energy storage equipment such as hydrogen storage tanks, storage batteries, chilled water storage tanks and heat storage tanks to achieve dynamic balance between supply and demand; using mobile resources such as electric vehicles, mobile emergency vehicles, mobile diesel generators, etc. to ensure the load supply when the power supply is insufficient due to extreme weather and other reasons, and improve the system elasticity.

[0023] The energy system equipment has a strong coupling relationship. The operation strategy of the established energy system is proposed, which is to determine heat based on cooling, determine hydrogen based on heat, and determine electricity based on hydrogen; electricity is used as the bottom-layer energy, and the consumption of renewable energy is given priority, followed by power supply from gas turbines. The excess electricity is stored in the storage battery, and the insufficient electricity is purchased from the power grid; the building cooling load is mainly supplied by the electric chiller and the ground source heat pump. When the rated power of the ground source heat pump is insufficient, the electric chiller is started, and the excess cooling capacity is stored in the chilled water storage tank; the building heating load is mainly supplied by the waste heat recovery of the gas turbine and the ground source heat pump. When the waste heat of the gas turbine cannot meet the demand, the ground source heat pump is started to supply heat, and the excess heat is stored in the heat storage tank; when the renewable energy and the gas turbine cannot meet the electricity load, the electricity consumed by the electrolyzer for hydrogen production is purchased from the power grid.

[0024] On this basis, as shown in Figure 2As shown in the figure, a method for optimizing the capacity of an energy system and coordinately scheduling the spatio-temporal decoupling of mobile resources under extreme disaster disturbances proposed by an embodiment of the present invention includes: According to the obtained extreme disaster event data, linking the device failure probability and line failure probability obtained through the dual-state resilience adaptive Markov and Monte Carlo processing, and coupling the load change parameters driven by extreme disaster events to form a disaster response database; Converting the fluctuations in the output of renewable energy and the deviation of user load demand into fuzzy variables through fuzzy chance constraints, and establishing a capacity configuration optimization model in combination with the disaster response database, with the minimum power levelized cost as the optimization goal, to generate a multi-energy complementary capacity configuration; Based on the multi-energy complementary capacity configuration, introducing mobile resources to establish an elastic enhancement scheduling architecture, and generating an elastic enhancement plan adaptable to extreme disaster events through implementing the topological reconstruction of the damaged road network of mobile resources, spatio-temporal transfer chain modeling, and coordinated regulation of action states.

[0025] First, by integrating multi-source extreme disaster event observation data, using the dual-state resilience adaptive Markov process to dynamically simulate the device failure probability and line failure risk, and coupling the dynamic incremental models of user cooling / heating / electricity loads driven by meteorological parameters, a disaster response database is constructed. This database breaks through the limitations of the decoupling of meteorological data, device failure models, and user load characteristics in traditional methods. This database not only covers the multi-dimensional failure mechanisms on the device side, but also couples the time-varying incremental models of cooling / heating / electricity loads driven by meteorological factors, breaking through the limitations of one-sided disaster risk assessment or static load prediction in traditional planning, and deeply exploring the impacts of extreme weather and natural disasters on the supply side and demand side.

[0026] On this basis, based on fuzzy chance constraints, converting the fluctuations in the output of renewable energy and the fluctuation range of user loads into credibility fuzzy variables, and combining with the set of failure scenarios generated by the disaster response database, a capacity configuration optimization model with the minimum power levelized cost as the goal is constructed. This model realizes the coordinated planning of the capacities of energy supply devices, energy storage devices, and energy conversion devices under extreme weather through multi-energy coupling constraints, embedding of device failure probabilities, and definition of fuzzy chance constraint boundaries. This method reduces the total system cost while ensuring the energy supply reliability in the scenario of high penetration of renewable energy, and solves the problem of insufficient elastic optimization caused by the simplification of meteorological disaster risk factors to fixed thresholds in existing planning. Through this comprehensive optimization, the adaptability and resilience of the system in the face of extreme climate conditions or natural disasters are significantly improved, and while pursuing the system economy, the ability of the system to cope with sudden extreme events is enhanced.

[0027] Furthermore, on the basis of multi-energy complementary capacity optimization, three types of mobile resources, namely mobile emergency power vehicles, electric vehicles, and diesel generators, are innovatively introduced, and elastic enhancement is achieved through implementing the topological reconstruction of the damaged road network of mobile resources, spatio-temporal transfer chain modeling, and coordinated action state mechanism.

[0028] Thus, through the collaborative decision-making of disaster response database-driven equipment capacity optimization and dynamic scheduling of mobile resources, the present invention realizes the dual elastic gain of strengthening the disaster resistance of fixed equipment and the rapid post-disaster response of mobile resources under extreme weather, providing an innovative solution for the design and operation of a highly resilient energy system.

[0029] To better understand the above technical solution, the exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0030] Specifically, the embodiment of the present invention provides a method for collaborative scheduling of energy system capacity optimization and spatio-temporal decoupling of mobile resources under extreme disaster disturbances, which includes: S1. According to multi-source extreme disaster event data, link the equipment failure probability and line failure probability under extreme disaster events obtained through two-state resilience adaptive Markov and Monte Carlo processing, and couple the weather-driven load change parameters to form a disaster response database.

[0031] Further, as Figure 3 shown, step S1 includes: S11. According to the extreme disaster event data collected at multiple observation points, form a multi-dimensional extreme disaster event database; wherein, the extreme disaster event data is a set of meteorological events including earthquakes, storms, extremely high temperature droughts, and extremely low temperature ice disasters that exceed the corresponding extreme thresholds.

[0032] In this step, historical extreme weather data of multiple meteorological observation stations in different regions is selected, and the collected extreme weather includes earthquakes, typhoons, droughts caused by extremely high temperatures, and ice disasters caused by extremely low temperatures.

[0033] Specifically, for earthquake disasters, relevant parameters such as earthquake time, magnitude, and epicenter area intensity need to be collected, and the collected earthquake data is mainly medium-level earthquakes above magnitude 5; for typhoon disasters, relevant parameters such as solar radiation intensity and real-time wind speed need to be collected; for high-temperature drought weather, relevant meteorological parameters such as the temperature and solar irradiance intensity on the day when the highest temperature of the day exceeds the extreme threshold need to be collected; for low-temperature ice disasters, relevant meteorological parameters such as the temperature of the frozen weather, real-time wind speed, freezing rain time, and freezing rain rate need to be collected.

[0034] Furthermore, analyze the impacts of extreme weather on the supply side and load side of the energy system: When an earthquake disaster occurs, the power lines are damaged and there is no power supply from the external power grid. The ground source heat pumps are damaged and unable to provide heating and cooling. The photovoltaic and wind turbines are damaged and unable to supply power. Some gas pipelines fail, and some roads are damaged or congested, resulting in changes in the dispatching routes of mobile emergency vehicles and affecting the restoration of load supply. Typhoon weather mainly affects overhead power lines, wind turbines, and photovoltaics. Extreme high-temperature weather often causes drought, leading to a decrease in power supply from the external power grid, limited output of photovoltaics and wind turbines. When the temperature is higher than 15°C, the efficiency of gas turbines decreases by 0.7% - 1% for every 1°C increase in temperature, and the cooling load of users increases when high-temperature weather occurs. Extreme low-temperature weather will result in ice and snow disasters. At this time, some overhead lines fail, the output of photovoltaics and wind turbines is limited, and the heating load of users increases when low-temperature weather occurs.

[0035] S12. Use the two-state resilient adaptive Markov process to analyze the state transition chain of the equipment, generate the equipment failure probability through the dynamic game of the failure rate and repair rate, and perform multi-scenario sampling simulation through the Monte Carlo method to generate a time-series set of equipment failure states.

[0036] In a specific example, referring to Figure 4 , to improve the resilience and reliability of the energy system, a method combining the two-state resilient adaptive Markov process and Monte Carlo simulation is used to generate the time-sequence scenarios of equipment failures. As shown in the two-state resilient adaptive Markov state transition model in Figure 4 , its core lies in constructing a time-varying transition mechanism for the operating state (normal / fault) of the equipment through the dynamic interaction of the failure rate and repair rate, and generalizing it to the external power grid circuit and natural gas underground pipeline. The two-state resilient adaptive Markov switching model is specifically as follows: ; ; ; ; ; In the formula, is the probability that the equipment j operates normally, is the probability that the equipment j fails. 1 represents that the operating state of the equipment j is normal, and 0 represents that the equipment j has a failure in operation. , is the time-varying repair rate; for the power grid and gas network, , is the number of repair teams, is the benchmark repair rate without additional repair resources, is the emergency repair reference quantity; for the energy system, , or are the normal operation time of the time-varying equipment and the time-varying repair time of the equipment respectively, is a number randomly generated from the uniform distribution [0, 1], is a number randomly generated from the uniform distribution [0, 1], is the state of the equipment j at t moment, is the failure rate, , K = {earthquake, storm, extreme high temperature and drought, extreme low temperature and ice disaster}, K is the set of disaster types, is the disaster K real-time intensity index, is the weight coefficient of the disaster K satisfying w k = 1, is the non-linear influence function of the disaster K used to standardize the physical dimensions of different disasters, is the quantified maintenance resource input for the suppression ability of the disaster intensity maintenance and disaster game intensity, R ( t ) ≥ D ( t ) when, γ ( t ) ≥ 0.5, indicating that maintenance is dominant and the probability of the normal state of the equipment is increased; R ( t ) < D ( t ) when, γ ( t ) < 0.5, indicating that the disaster suppresses and increases the failure risk, is the reference threshold of the resource-disaster ratio.

[0037] Furthermore, referring to Figure 5 , the steps of fault extraction based on Monte Carlo are as follows: (1) Define the model parameters: First, define the state. State 0 indicates that the equipment is in the normal working state, and state 1 indicates that the equipment is in the operating failure state; Second, calculate the probability j of the normal working state of the equipment and the probability j of the operating failure state of the equipment ; Determine the time interval. In this embodiment, the time step is set to 1 hour. Usually under normal circumstances, the time step of the operation cycle is shorter than the maintenance time of the equipment. Therefore, within this time step, the equipment is considered irreparable and in a failure state. Finally, obtain the j interruption model of the equipment.

[0038] (2) Initialize the simulation: First, set the initial state of the equipment. Usually, the initial state of the equipment is considered to be the working state; second, determine the number of Monte Carlo simulations. Initialize 100 simulations to obtain sufficient data for analysis.

[0039] (2) Conduct the simulation: Each simulation starts from the initial state. At each time step, randomly determine whether the equipment undergoes a state transition according to the probability of the current equipment and the transition state, and record the state of the equipment and the time of the transition.

[0040] (3) Data collection: Collect the time when the equipment enters the failure state in each simulation, and calculate key indicators such as the failure rate and the mean time to failure.

[0041] In this embodiment, by breaking through the limitations of the traditional static reliability model through the dynamic failure rate - repair rate game mechanism, combined with Monte Carlo iteration under the constraint of the disaster duration, high-fidelity simulations of complex scenarios such as earthquake-induced cascading failures of gas pipelines and hourly line breaks caused by typhoons are realized, providing high-confidence input boundary conditions for subsequent capacity configuration optimization.

[0042] S13. According to the spatial distribution intensity and time accumulation parameters under the current extreme disaster event, simulate the dynamic diffusion process of the extreme disaster event through parameter space gradient mapping and time accumulation effect analysis, and generate a set of line failure probabilities including energy network lines and pipe networks.

[0043] Specifically, for different types of extreme disaster events, the following steps are used to dynamically generate a set of failure probabilities of energy network lines and pipe networks: (1) In the earthquake scenario, based on the spatial gradient distribution of the intensity in the epicenter area, combined with the correlation parameters fitted from historical earthquake data, analyze the seismic damage risk gradient of different sections along the gas pipeline as follows: ; In the formula, is the earthquake occurrence frequency, is the earthquake magnitude, and its size depends on the intensity in the earthquake epicenter area ; a and b are fitting parameters, and the fitting parameters in different regions need to be obtained by fitting local historical earthquake data.

[0044] Judge the earthquake hazard rate according to the intensity in the epicenter area, and thus calculate the failure probability of the gas pipeline: ; ; In the formula, the intensity of the earthquake epicenter area, is the earthquake hazard rate, is the failure probability of the gas pipeline, is the pipeline length.

[0045] In the earthquake scenario, the energy supply system has suffered serious damage, presenting a complex and severe energy supply and demand situation. The characteristics of the energy supply of the energy system are as follows: 1) Interruption and limitation of energy supply: The external power grid lines and natural gas pipelines are damaged, resulting in a complete interruption of the external power grid power supply, a significant reduction in the underground natural gas pipelines, and directly restricting the power generation of gas turbines. At the same time, renewable energy sources such as photovoltaic and wind turbines are damaged by the earthquake and cannot supply power normally, and the energy supply method has been severely hit. 2) Associated impact of the energy supply system: The damage to the power supply system not only leads to insufficient power supply but also has a chain reaction on building heating and cooling. The ground source heat pump is damaged and cannot supply heating and cooling normally. The electric chiller still needs to consume electricity to operate under the condition of tight cooling supply, further exacerbating the contradiction between power supply and demand. 3) Adjustment of the energy supply strategy: In the extremely tight power supply situation, in order to give priority to meeting the energy demand of buildings, the electrolytic cell originally used for hydrogen production stops working, and the limited resources are centrally allocated. The electrical load on the demand side is mainly met by the discharge of batteries and mobile resources. At the same time, some non-critical electrical loads are restricted or reduced.

[0046] (2) In the typhoon scenario, extract the ratio of the real-time wind speed to the designed wind speed under the typhoon movement path, identify the designed wind speed threshold and the duration of the typhoon weather. The failure probability of the wire under the typhoon is: ; ;

[0047] In the formula, is the wind speed at time t ; is the designed wind speed; is the maximum wind speed that the line can withstand; is the length of the line; is the duration of the typhoon weather.

[0048] In the typhoon scenario, the characteristics of energy supply among energy system equipment are as follows: 1) Fault simulation and detection: Using the Batts typhoon model, integrating the typhoon wind field model and the typhoon movement attenuation model, and obtaining typhoon data such as wind speed and wind direction information to dynamically simulate and characterize the transmission line fault problem, providing a basis for the subsequent response of power supply equipment. 2) Energy supply interruption: When the typhoon passes through the external lines of the energy system and causes damage, it leads to a complete interruption of the external power grid supply. At the same time, renewable energy sources such as photovoltaic and wind turbines are damaged due to excessive wind speed and cannot supply power normally. At this time, the gas turbine undertakes the main power supply task, and the battery and mobile resources cooperate as emergency power supply equipment to jointly ensure power supply in the typhoon situation. 3) Adjustment of energy supply strategy: The main force of power supply changes to the gas turbine, which undertakes the task of meeting the main power load. The battery and mobile resources cooperate as emergency power supply equipment to jointly ensure power supply in the typhoon situation and relieve the contradiction between power supply and demand.

[0049] (3) In the ice storm scenario, according to the spatial heterogeneity of the freezing rain rate and the persistence of the freezing rain time, calculate the spatio-temporal evolution trajectory of the ice thickness on the transmission line as follows: ; ;

[0050] In the formula, is the thickness of the ice; is the freezing rain time; is the freezing rain rate; is the density of the ice; is the density of the freezing rain; is the liquid water content, calculated by the formula ; is the ice load per unit wire line; is the conductor diameter; is the wind load; is a constant coefficient, in the unit of ; is the cross-boundary factor; is the combined ice ball load, calculated from the ice load and the wind load.

[0051] Based on the spatio-temporal evolution trajectory of the ice thickness, establish the following probability model of the transmission line under the ice storm: ; ; In the formula, is the fault probability per unit line; and are the first threshold and the second threshold of the ice ball load respectively.

[0052] In the extreme weather scenario of ice storms, the heating load increases, and the energy supply operation and linkage in the equipment room present the following specific states: 1) Energy supply is blocked: The ice storm causes the photovoltaic and wind turbines to be affected by the ice thickness, and their power generation capacity is severely limited. At the same time, the external lines are overloaded due to icing, which limits the power supply capacity of the power grid. The normal power supply system is impacted, and various original energy supply channels are ineffective or weakened to varying degrees, and the overall energy supply is in trouble; 2) Energy supply dominance and cooperation: The gas turbine becomes the main power supply equipment during the ice storm. When the power generation of the gas turbine still cannot meet the power demand, mobile resources are quickly put into use to supplement the power.

[0053] S14. Construct a temperature-driven load growth model. By introducing humidity correction terms, wind speed correction terms, and irradiance correction terms, quantify the load dynamic increment of extreme low temperature events or extreme low temperature events, and form a time-series load dynamic parameter set.

[0054] Specifically, the dynamic load growth evolution models for drought weather caused by high temperature and ice storm weather caused by low temperature are as follows: ; In the formula, is t the predicted load at the moment when extreme weather occurs, is t the predicted load at the moment when extreme weather does not occur, is the load increment at the moment t after extreme weather occurs, which is related to the perceived temperature ; is the neural network load prediction model, and the predicted load is related to the perceived temperature. represents t the actual air temperature at the moment, represents t the air relative humidity correction term at the moment, represents the wind speed correction term, represents the solar radiation correction term. Among them, the neural network load prediction model is a data-driven mathematical function, and its core function is to predict the load under specific meteorological conditions by learning the hidden laws between historical meteorological data and power load. The predicted load output by the model reflects the quantitative impact of the combined effects of temperature, humidity, wind speed, and radiation under normal meteorological conditions on electricity consumption behavior. The neural network load prediction model can adopt network structures such as LSTM (Long Short-Term Memory Network), CNN (Convolutional Neural Network), or Transformer.

[0055] In extremely high temperature scenarios, all types of power generation equipment are significantly affected, as follows: 1) Limited renewable energy power generation: Excessively high temperatures will reduce the conversion efficiency of photovoltaic modules, resulting in reduced power generation. At the same time, high temperatures may affect the normal operation of mechanical parts and electronic components inside the wind turbine, thereby limiting the power generation capacity of the wind turbine, making it difficult for photovoltaics and wind turbines, which were originally important sources of renewable energy power generation, to fully exert their efficiency under extremely high temperatures. 2) Limited traditional energy power generation: Under extremely high temperatures, gas turbine power generation is also limited. Excessively high temperatures will reduce the density of air entering the gas turbine, resulting in a decrease in combustion efficiency, thereby limiting the power generation of the gas turbine and making it difficult to maintain normal power generation levels.

[0056] S15. The equipment fault state set, line failure probability set and load dynamic parameter set are aligned in time and space, and combined with the multi-dimensional extreme disaster event database to generate a disaster response database. Through the time and space grid alignment technology, the equipment fault state set, line failure probability set and load dynamic parameter set are multi-dimensionally coupled to generate a disaster response database.

[0057] S2. Through fuzzy opportunity constraints, the fluctuation of renewable energy output and the deviation of user load demand are converted into fuzzy variables. Combined with the disaster response database, a capacity configuration optimization model is established. Taking cost minimization as the optimization goal, multi-energy complementary capacity configuration is generated.

[0058] Furthermore, if Figure 6 As shown, step S2 includes: S21. In response to regional energy demand, a system topology including energy supply equipment, energy storage equipment and energy conversion units is constructed based on a disaster response database, and capacity configuration elements including equipment output set, equipment status set and efficiency parameter set are configured.

[0059] Specifically, the equipment output set is used to characterize the dynamic balance state of energy production and demand of the energy system at time t. It includes the energy supply efficiency of energy supply equipment such as wind turbines and photovoltaics in the energy system, building electrical load demand, heat load demand and cooling load demand, hydrogen fuel cell vehicle hydrogen, load demand, energy storage equipment SOC, etc., to fully reflect the output information of the energy system at the current moment. Therefore, the output of each device in the energy system at time t is expressed as: ; In the formula, for t Electricity price at any time, For equipment i exist t The amount of electricity generated at the time; For equipment i exist t Cooling capacity at any time; For equipment i existt The heating capacity at a certain moment; For the electro-hydrogen conversion device i At t The hydrogen production capacity at a certain moment; They are respectively the building's electrical load demand, heating load demand, and cooling load demand at time t; Is the capacity of energy storage device i at time t.

[0060] The device status set is used to describe the operation reliability of system devices and the charging and discharging dynamics of energy storage. It includes the operation status (normal operation or fault status) of all devices in the energy system and the charging and discharging status of energy storage devices, etc., to comprehensively reflect the operation status information of each device in the energy system at the current moment. Therefore, t The status of each device in the energy system at a certain moment is expressed as: ; In the formula, Indicates the operation status of device i At t A certain moment, obtained from formula (14). When it is 1, it means that device i is in a normal operation state. When Is 1, it means that device i is in a normal operation state. When Is 0, it means that device i Is in a running fault state; They are respectively the charging state and discharging state of energy storage device i At t A certain moment. When the energy storage device i Is in a fault state, Or Is 0. When in a normal operation state, Or Is 1, and .

[0061] The energy efficiency parameter set is used to quantify the energy conversion and transmission losses of devices, and it includes: the efficiency of energy supply devices, the energy storage loss coefficient, and the energy conversion efficiency.

On the basis of the multi - energy complementary capacity configuration, introduce mobile resources including mobile emergency power vehicles, electric vehicles, and diesel generators as elastic supplementary energy supply units, and establish an elastic improvement scheduling framework for the coordination of fixed equipment and mobile resources.

[0067] S32. According to the obtained disaster damage information, remove the damaged road network nodes and edge sets, reconstruct the road network topology, and generate a set of feasible scheduling paths that minimize the distance from the starting point to the target energy system for mobile resources.

[0068] In this embodiment, as Figure 8 shown, the road topology network includes nodes A - M and edge sets, where the edge weights represent the distances between adjacent nodes. When a road is damaged due to an earthquake disaster, the scheduling path of mobile emergency resources is blocked, resulting in a delay in load restoration. To address this problem, the following steps are executed: First, based on the road damage information collected after the earthquake (such as bridge collapse, road surface cracking), identify the damaged nodes and edge sets (such as the road interruption between nodes D - E). Second, remove the damaged edge sets and update the road network adjacency matrix to generate a sparse road network structure under the post - disaster reachability constraint; furthermore, use Dijkstra's algorithm to search for the optimal scheduling path of the mobile emergency power vehicle from the starting point (such as node A) to the target energy system (such as node M) in the reconstructed road network, and use Dijkstra's algorithm to search for the shortest driving route of mobile resources, and output a set of feasible paths that minimize the distance (such as A→B→F→L→M, A→B→G→K→M, A→C→H→J→M, etc.).

Analyze the departure timestamp, estimated arrival timestamp, driving duration interval, and charging stop times of mobile resources to generate time - chain features including time availability constraints, and extract the starting position coordinates, target energy supply station coordinates, and path node coordinate sets of mobile resources to generate space - chain features including space connectivity constraints.

[0070] In this step, the travel chain of electric vehicles is divided into two parts: the time chain and the space chain; the time chain mainly describes the time distribution of electric vehicle travel, including: departure time ( ), arrival time ( ), driving time ( ), and parking time ( ); the space chain mainly describes the spatial transfer of electric vehicle travel, including: starting point ( ), end point ( ), driving path ( ); The time chain and space chain are expressed as: ; ; S34. Verify the time chain characteristics and space chain characteristics. Based on the spatio-temporal feature combinations that pass the verification, calculate the maximum service radius, shortest response time, and continuous power supply duration threshold of the mobile resources, and form the spatio-temporal schedulable boundary. Specifically, establish the association rules between the time chain and the space chain, and implement the spatio-temporal consistency verification rules and spatio-temporal conflict detection to screen out the scheduling schemes with overlapping time window conflicts, path node failures, or unavailable charging periods at stops.

[0071] S35. Obtain the action set representing the power supply behavior parameters of the mobile resources according to the energy supply characteristics of the obtained mobile resources, and construct the state set representing the operating state of the mobile resources according to the mutual exclusion constraints of the device operation.

[0072] In this step, the mobile resource action set mainly includes the charging and discharging power of electric vehicles ( ), and the electric power consumed during driving ( ), the power supply power of mobile emergency power supply vehicles ( ), and the power generation power of mobile diesel generators ( ), so as to comprehensively represent the situation of scheduling mobile resources at a certain moment to restore the building energy load after extreme weather or natural disasters. The action sets of mobile resources such as electric vehicles (Electric vehicles, EVs), mobile emergency vehicles (Mobile energystorage system, MESSs), and mobile diesel generators (Diesel Generator, DGs) are expressed as: ; The mobile resource state set mainly includes the charging state of electric vehicles ( ), and the discharging state ( ), the start-stop state of mobile emergency vehicles ( ), the start-stop state of mobile diesel generators ( ), so as to comprehensively represent the scheduling states of mobile resources such as electric vehicles; the mobile resource state set is expressed as: ; In the formula, when the i th electric vehicle is in the charging state the value is 1, when the electric vehicle is in the discharging state the value is 1, and it cannot be charged and discharged simultaneously ; When the mobile emergency power supply vehicle arrives at the energy system and discharges to supply the building energy demand The value is 1; conversely, when there is no need to move the emergency vehicle for discharging or the mobile emergency power vehicle has not arrived at the energy system The value is 0; when the mobile diesel generator is in the power supply state The value is 1; conversely, it is 0.

[0073] S36. In the elastic promotion scheduling architecture, with the goals of minimizing the total cost of mobile resource scheduling, minimizing the load curtailment amount, and minimizing the path energy consumption, based on the spatio-temporal schedulable boundary, through a multi-layer collaborative optimization algorithm, dynamically solve the parameters of the action set, the flag sequence of the state set, and the optimal solution of the priority of the feasible scheduling path set of mobile resources, and generate an elastic promotion plan adaptable to extreme disaster events.

[0074] In order to quickly restore the load supply and further improve the system elasticity, with the core optimization goals of minimizing the operating cost of mobile resources, maximizing the load restoration amount, and minimizing the path energy consumption within the scheduling period, construct the following multi-objective function system: ; ; ; ; ; In the formula, represents the number of days of continuous occurrence of extreme weather or natural disasters; , , and are the scheduling costs of EV, DG, and MESS and the amount of unsupplied load respectively; is the path energy consumption during the scheduling of electric vehicles; , and are the unit energy supply prices respectively; and are the discharge amounts of EV and MESS respectively; is the amount of diesel consumed by DG for power supply; , , are the amounts of unsupplied electric load, unsupplied cooling load, and unsupplied heating load respectively.

In the inner layer architecture, the upper layer honey badger population performs the dual-objective optimization of the global scheduling cost and the load reduction amount. The lower layer bird flock population optimizes the priority of the set of feasible scheduling paths with the goal of minimizing the path energy consumption through the path memory bank sharing mechanism. In the outer layer architecture, the simulated annealing algorithm model receives the optimal solution output by the inner layer architecture as the initial solution and performs perturbation optimization.

[0078] S354. For each honey badger individual, match the lowest energy consumption sequence of the corresponding path chain from the initial bird flock population, calculate the total cost of mobile resource scheduling, the load reduction amount, and the path energy consumption index, and aggregate them into a comprehensive performance index through normalized weights to generate a dual-driven scale of prey odor concentration - migration attraction.

Feed the repaired individuals back to the corresponding populations to update the distribution of the honey badger and the bird flock.

[0083] S359. After the inner-layer architecture is iterated, the current optimal scheduling scheme is input into the outer-layer simulated annealing algorithm model. New solutions are generated through Gaussian perturbation, and the fitness differences are calculated. A probabilistic acceptance strategy is used to jump out of the local optimum, and a solution that satisfies the spatio-temporal schedulable boundary conditions and is jointly optimal for the dual objectives is output, including the parameter set of mobile resource actions, the state set flag sequence, and the priority of the feasible scheduling path set. Specifically, after the inner-layer dual-model algorithm is iterated, the currently found optimal scheduling scheme is obtained, and the currently found optimal scheduling scheme is output and used as the initial solution for the outer-layer simulated annealing optimization stage to further optimize and adjust the scheduling scheme. In the simulated annealing optimization stage, new solutions for the parameter set of mobile resource actions, the state set flag sequence, and the priority of the feasible scheduling path set that are jointly optimal for the dual objectives are generated by perturbing the initial solution, and the fitness differences are calculated. If the difference is less than 0, the new solution is accepted. If the difference is greater than 0, the acceptance probability of the new solution is calculated, and the new solution is selectively accepted according to the acceptance probability. When the simulated annealing algorithm layer reaches the maximum number of iterations at different temperatures according to the cooling coefficient, the multi-layer collaborative optimization is terminated.

Refer to Figure 11 , and its core logic is divided into the following steps: Step 1: Obtain the historical extreme weather data of multiple different meteorological station observation points. The extreme weather and natural disasters collected mainly include earthquakes, typhoons, extreme high-temperature weather, and extreme low-temperature weather. And establish an extreme weather database based on the historical extreme weather data; Step 2: Simulate the device state transition probability through a two-state resilience adaptive Markov process, combine Monte Carlo random sampling to generate device cascading failure scenarios, construct a weather disaster energy system response database including device output limitation, load dynamic disturbance, and energy supply-demand imbalance, and generate a disaster response database based on the extreme weather database; Step 3: Define the uncertainty of wind-solar power generation as a fuzzy variable using fuzzy chance constraints and establish a fuzzy chance constraint model, and generate an energy system configuration optimization model under extreme weather through the disaster response database.

The optimized energy system can effectively reduce the interruption of energy supply under extreme events and improve the resilience and reliability of the system; Step 4: To further enhance the resilience of the energy system, on the basis of capacity configuration, couple mobile resources such as mobile emergency power vehicles, mobile diesel generators, and electric vehicles.
