Description
Technical Field
[0001] This application relates to the field of energy optimization, specifically to an operational method for Antarctic research stations based on the synergy of virtual energy storage and waste heat recovery. Background Technology
[0002] Antarctica holds irreplaceable strategic value as a crucial region for monitoring climate change and exploring the frontiers of Earth science. However, as a cutting-edge base for polar scientific research, Antarctic research stations have long relied on diesel generators for energy supply. Although this model boasts high power reliability thanks to mature fuel storage and transportation technologies, it may lead to environmental pollution, high carbon emissions, and significant logistics costs.
[0003] To elaborate, the traditional polar integrated energy model does not construct a dynamic output-limited model that considers the evolution of extreme Antarctic weather (such as wind turbine icing and photovoltaic snow cover), making it difficult to accurately capture the nonlinear dynamic spatiotemporal dependence between the extreme polar environment and the multi-energy complementary system, resulting in inaccurate assessment of the system's energy supply reliability during sudden weather changes.
[0004] Meanwhile, the traditional research station operation strategy does not consider the deep coupling of low-grade waste heat from the operation of hydrogen energy equipment with flexible heat load, and lacks the exploration of the time-domain flexible heat storage characteristics of building envelope and water heater tank, resulting in waste of waste heat resources and high consumption of fossil energy.
[0005] In addition, given the high uncertainty of power output from wind and solar power in Antarctica, there is a lack of a dynamic scheduling model that does not require pre-setting a prior probability distribution and can balance computational efficiency and robustness. This makes scheduling schemes prone to failure due to the scarcity of historical big data in the polar regions and large prediction biases, resulting in a significant decrease in the economic efficiency and risk resistance of the system.
[0006] Therefore, it is urgent to reduce carbon emissions from research stations in order to achieve a sustainable development plan for Antarctic scientific research. Summary of the Invention
[0007] To address the aforementioned issues, this application proposes a method for operating Antarctic research stations based on the synergy of virtual energy storage and waste heat recovery, including: Source-side modeling is performed; wherein, the source-side modeling includes: modeling a polar wind power generation model under icing conditions and a polar photovoltaic power generation model under snow conditions using meteorological parameters; and modeling a polar diesel generator output model based on temperature difference and a hydrogen energy equipment model describing the hydrogen production of a PEM electrolyzer using the first operating parameters corresponding to the energy production equipment. And load-side modeling is performed; wherein, the load-side modeling includes: modeling the electric heating model under thermal balance constraints and the conventional energy consumption model described by the power equation using the first working parameters corresponding to the energy production equipment and the building parameters corresponding to the scientific research station building; and modeling the waste heat recovery water heater model described by the thermal dynamic change equation of water temperature using the second working parameters corresponding to the energy consumption equipment. And perform storage-side modeling; wherein, the storage-side modeling includes: modeling a battery energy storage model under the constraints of multiple operating boundaries in the spatiotemporal dimension through the third operating parameters corresponding to the energy storage device, and a hydrogen storage tank model described by the balance equation of dynamic changes in hydrogen storage capacity; Power balance constraints are performed based on the source-side modeling, the load-side modeling, and the storage-side modeling. Based on the source-side modeling, load-side modeling, storage-side modeling, power balance constraints, and energy optimization objective function, a deterministic optimization model is obtained. Based on the deterministic optimization model and the box-type uncertainty set to which the output of the photovoltaic array and wind turbine generator belongs, a two-stage sub-Blu-ray bar optimization scheduling model is established. By introducing an imprecise tolerance during the iteration process, the accuracy of solving the main problem and the convergence threshold are adaptively adjusted to solve the two-stage sub-Bruker optimization scheduling model and obtain a scheduling scheme; the scheduling scheme is used to schedule at least one of the energy production equipment, the energy consumption equipment, and the energy storage equipment.

Using the operating power of the PEM electrolyzer and the rate at which the hydrogen fuel cell consumes hydrogen as inputs, a model of the hydrogen energy equipment is obtained by establishing a linear conversion relationship between the PEM electrolyzer's hydrogen production process and a mathematical model of the hydrogen fuel cell.
[0010] In one example, the electric heating model under thermal balance constraints and the conventional energy consumption model described by the power equation are modeled using the first operating parameters corresponding to the energy production equipment and the building parameters corresponding to the research station building; and the waste heat recovery water heater model described by the thermal dynamic change equation of water temperature is modeled using the second operating parameters corresponding to the energy consumption equipment. Specifically, this includes: Based on the electrical energy consumed by the electric heating equipment in the first working parameters and the thermal resistance and heat capacity parameters in the building parameters, the electric heating model is obtained by constructing the thermal balance constraints of the scientific research station's envelope and the indoor thermal balance constraints using a thermal resistance-heat capacity network based on the heating capacity of the electric heating equipment. Based on the heat generation power of the electrolyzer and hydrogen fuel cell and the heat recovery efficiency of the heat exchanger in the second working parameters, a waste heat recovery water heater model is obtained by establishing the thermal dynamic change equation of the water temperature in the water heater and setting the upper and lower limits of the user's comfortable water temperature. Based on the operating parameters of the conventional electrical load equipment in the first working parameters, a conventional energy consumption model is modeled by establishing the power equations corresponding to each conventional electrical load equipment and aggregating them.
[0011] In one example, the battery energy storage model constrained by multiple operational boundaries in the spatiotemporal dimensions and the hydrogen storage tank model described by the balance equation of dynamic changes in hydrogen storage capacity are modeled using the third operating parameters corresponding to the energy storage device. Specifically, this includes: Based on the battery's operating parameters in the third operating parameters, a battery energy storage model is obtained by establishing multiple operating boundaries, including charging and discharging power constraints, state of charge constraints, charging and discharging state mutual exclusion constraints, and power balance constraints at the beginning and end of the scheduling cycle. Based on the hydrogen mass flow rate of the electrolyzer hydrogen production and fuel cell hydrogen consumption processes in the third working parameters, as well as the charging and discharging status flag of the hydrogen storage tank, a model of the hydrogen storage tank is obtained by establishing a balance equation for the dynamic change of hydrogen storage capacity in adjacent scheduling periods and setting minimum and maximum energy storage capacity constraints for the hydrogen storage tank.
[0012] In one example, a deterministic optimization model is obtained by integrating the source-side modeling, the load-side modeling, the storage-side modeling, the power balance constraints, and the energy optimization objective function, specifically including: With the goal of minimizing carbon emissions, an energy optimization objective function is constructed; the equipment corresponding to carbon emissions includes diesel generators, electric heating equipment, and water heaters. A deterministic optimization model is obtained by integrating the source-side modeling, load-side modeling, storage-side modeling, power balance constraints, and energy optimization objective function. The deterministic optimization model includes the energy optimization objective function and the corresponding optimization constraints. These constraints include inequality constraints and equality constraints within the model set, constraint relationships between optimization variables, and the predicted values of uncertain variables for each time period. The model set includes the source-side modeling, load-side modeling, storage-side modeling, and power balance constraints.
[0013] In one example, based on the deterministic optimization model and the constructed box-type uncertainty set to which the photovoltaic array and wind turbine output belong, a two-stage sub-Bruker optimization scheduling model is established, specifically including: Construct a box-shaped uncertainty set to which the output of the photovoltaic array and the wind turbine generator belong; the uncertain variables in the box-shaped uncertainty set are the uncertain variables of the output of the photovoltaic array and the wind turbine generator introduced after considering uncertainties; Based on the deterministic optimization model, expressed in a compact typical matrix form, a two-stage sub-Bruker optimal scheduling model is established. The optimization variables in the first stage correspond to the charging and discharging states of the battery and the hydrogen storage system. The optimization variables in the second stage correspond to the wind power generation under icing conditions, the photovoltaic power generation under snow conditions, the output power of the diesel generator in time period t, the operating power of the electrolyzer in time period t, the output power of the hydrogen fuel cell in time period t, the electrical energy consumed by the electric heating equipment, the indoor temperature in time period t, the wall temperature of each numbered wall, the power of the water heater in time period t, the water temperature in the water heater tank in time period t, the heat power recovered by the electrolyzer and hydrogen fuel cell through the heat exchanger in time period t, the discharge power of the battery in time period t, the charging power of the battery in time period t, the power required by other equipment at the Antarctic research station, and the aforementioned uncertain variables.
[0014] In one example, by introducing an imprecise tolerance during the iteration process, the accuracy of solving the main problem and the convergence threshold are adaptively adjusted to solve the two-stage bibliometric optimization scheduling model, resulting in a scheduling scheme, specifically including: Based on the power output of wind and light under the worst-case scenario, the lower bound of the main problem is obtained by solving the main problem and updating the lower bound of the main problem, and by solving the main problem and recording the optimal decision value of the main problem; the main problem corresponds to the optimization variable in the first stage. Based on the optimal decision value of the primary problem, the value of the wind and solar power output under the worst-case scenario is obtained by solving the sub-problems; the sub-problems correspond to the optimization variables in the second stage. According to duality theory, the min problem in the max-min bi-level optimization corresponding to the subproblem is transformed into a max problem, and the max problems in the max-min bi-level optimization of the max problem domain are merged to obtain the dual problem; Based on the bilinear term in the dual problem, the box-shaped uncertainty set is reformulated as follows: whether to take the lower limit of the fluctuation range is represented by a binary variable, and an uncertainty adjustment parameter is introduced. For the bilinear term, it is linearized using the Big M method, and a continuous auxiliary variable is introduced to iteratively solve the subproblem. Based on the lower bound of the main problem and the upper bound of the subproblems, the system determines whether to stop iteration and return to the optimal solution, or to continue iteration, by judging whether the actual relative gap is close enough to the preset convergence gap.
[0015] In one example, the method further includes: If the actual relative gap does not meet the preset convergence gap, then the inaccurate tolerance is determined by the preset convergence gap, and the inaccurate tolerance is compared with the upper bound of the subproblem. If the actual relative gap after iteration satisfies the non-precise tolerance, then update the lower bound of the main problem, reduce the relative optimal gap, and return to the main problem for the next iteration; If the actual relative gap after iteration does not meet the non-precise tolerance, the subproblem is solved again, a new worst-case scenario is obtained, and the main problem is returned for iteration.
[0016] The operational method for Antarctic research stations based on the synergy of virtual energy storage and waste heat recovery proposed in this application can bring the following beneficial effects: 1. A wind-solar-hydrogen-storage multi-energy complementary model based on real meteorological datasets in Antarctica was constructed. This model effectively overcomes the shortcomings of traditional models in predicting inaccurate results in extreme polar environments, accurately depicts the power output limitation caused by ice and snow cover, and ensures uninterrupted and reliable power supply for the research station under extreme weather conditions.
[0017] 2. A low-carbon operation strategy that considers the collaboration between virtual energy storage system and waste heat recovery water heater is proposed, which effectively solves the problems of waste heat resources and heat supply and demand imbalance. Under the premise of fully guaranteeing the polar thermal environment and hot water demand, energy cascade utilization is realized, and carbon emissions are significantly reduced.
[0018] 3. A two-stage partial Bruker optimization strategy was proposed and solved using the DTA-C&CG algorithm. This effectively mitigated the impact of strong wind and solar fluctuations and the lack of precise probability distribution on the scheduling scheme. While ensuring that the calculation speed meets the real-time convergence requirements, it significantly improved the risk resistance and robustness of the low-carbon operation of the research station.

[0081] S105: By introducing an imprecise tolerance during the iteration process, the accuracy of solving the main problem and the convergence threshold are adaptively adjusted to solve the two-stage sub-Bruker optimization scheduling model and obtain a scheduling scheme; the scheduling scheme is used to schedule at least one of the energy production equipment, the energy consumption equipment, and the energy storage equipment.
[0082] To address the low efficiency of traditional two-stage bilabial bar optimization methods, this application proposes a DTA-C&CG algorithm. This algorithm introduces an imprecise tolerance during the iteration process. It adaptively adjusts the accuracy of solving the main problem and the convergence threshold, effectively avoiding redundant iterations while ensuring the accuracy of the global optimal solution, and significantly improving the model's solution efficiency.
[0083] Specifically, based on the wind and solar power output under the worst-case scenario, the lower bound of the main problem is obtained by solving the main problem and updating the lower bound of the main problem, and by solving the main problem and recording the optimal decision value of the main problem; the main problem corresponds to the optimization variables in the first stage.
[0084] Let the relative optimal gap of the main problem be... This is used to indicate the precision of the calculation result for the main problem. At the same time, in order to achieve... The verification and adjustment require the introduction of a preset convergence gap. Non-precise tolerance The iteration number k and the valid iteration index identifier I.
[0085] Decomposing Formula 52, the main problem is shown in Formula 54 below: Formula 54; Where k is the current iteration number, with an initial value of 1; I is the effective optimal iteration index, with an initial value of 0; LB is the lower bound of the main problem, with an initial value of 0, used to dynamically improve the solution accuracy of the main problem; The solution to the subproblem after the l-th iteration; This represents the value of the wind and light output under the worst-case scenario after the l-th iteration.
[0086] When according to When solving the main problem, we obtain the upper bound of the main problem. Lower Boundary If the conditions are met If the result obtained in this iteration is better, then the effective iteration count I=k is updated, and the lower bound of the main problem is also adjusted. As the new lower bound (LB), And record the optimal decision value of the main problem as Then substitute it into the subproblem to solve it.
[0087] Based on the optimal decision value of the primary problem, the value of wind and solar power output under the worst-case scenario is obtained by solving the sub-problems; the sub-problems correspond to the optimization variables in the second stage.
[0088] The decomposed subproblems are in the form shown in Formula 55: Formula 55; According to duality theory, the min problem in the max-min bi-level optimization corresponding to the subproblem is transformed into the max problem, and the max problems in the max-min bi-level optimization of the max problem domain are merged to obtain the dual problem.
[0089] Considering that the max-min bi-level optimization is an NP-hard problem, it is usually difficult to solve. However, when (x, u) is given, the inner minimization is a linear problem. The min can be transformed into the max form according to duality theory, and then merged with the outer max problem. The resulting dual problem is shown in Equation 56. Formula fifty-six; Based on the bilinear term in the dual problem, the box-shaped uncertainty set is reformulated as follows: whether to take the lower limit of the fluctuation range is represented by a binary variable, and the form of uncertainty adjustment parameter is introduced.
[0090] The formula contains bilinear terms. For the Antarctic research station corresponding to the embodiments of this application, when the wind and solar power output is taken as the left boundary of Formula 51, the carbon emissions generated by the Antarctic research station are higher. Therefore, the uncertainty set U to which the wind and solar power output belongs can be restated as shown in Formula 57: Formula 57; in, This is a binary variable; a value of 1 indicates that the wind and solar power output reaches the minimum of the uncertain set. and These are the uncertainty adjustment parameters corresponding to the output of the photovoltaic array and the wind turbine generator, respectively, with values ranging from 0 to... The integer within represents the total number of time periods within the scheduling cycle where the wind and solar power output values are at the lower limit of the fluctuation range described in Formula 57. The smaller the value, the more risky the model is, and therefore it can be used to adjust the conservatism of the scheme.
[0091] For the bilinear term, we linearize it using the Big M method and introduce a continuous auxiliary variable to iteratively solve the subproblem.
[0092] However, since substituting the expression for the uncertain variable in Formula 57 into Formula 56 results in a product of a continuous variable and a binary variable, the Big M method is used to linearize it, yielding Formulas 58 and 59: Formula fifty-eight; Formula 59; in, , For continuous auxiliary variables, The upper bound of the dual variable can be a sufficiently large positive real number.
[0093] Based on the lower bound of the main problem and the upper bound of the subproblems, the system determines whether to stop iteration and return to the optimal solution, or to continue iteration, by judging whether the actual relative gap is close enough to the preset convergence gap.
[0094] Record the worst-case scenario obtained from the subproblem and update the upper bound UB of the original problem. When the actual relative gaps are sufficiently close, as shown in Equation 60, stop the iteration and return the optimal solution. : Formula Sixty; If the actual relative gap does not meet the preset convergence gap, the inaccurate tolerance is determined by the preset convergence gap, and the inaccurate tolerance is compared with the upper bound of the subproblem.
[0095] If Formula 60 is not met, then the non-precise tolerance needs to be compared according to Formula 61: Formula 61; in, The actual target value of the main problem. To ensure system reliability, the following non-precise tolerances must be met. It should satisfy the conditions shown in Formula 62: Formula 62; If the actual relative gap after iteration satisfies the non-precise tolerance, then update the lower bound of the main problem, reduce the relative optimal gap, and return to the main problem for the next round of iteration; if the actual relative gap after iteration does not satisfy the non-precise tolerance, then resolve the subproblem, obtain the new worst-case scenario, and return to the main problem for iteration.
[0096] If Equation 61 holds, then let k = I and update the lower bound of the main problem. At the same time, reduce the relative optimal gap. Then return to the main problem for the next iteration; if formula sixty-one does not hold, the subproblems need to be solved again to obtain the new worst-case scenario, and then return to the main problem for iteration.
