[0046] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it is understood that various forms of implementing the present disclosure are not limited by the embodiments set forth herein. Rather, the embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0047] Please refer to Figure 1 As shown, the present application provides a method for allocating flexibility resources in the power market, including:

[0048] S101. Acquire real-time measurement data, weather forecast data, and equipment status data of power grid nodes;

[0049] Collect real-time power system measurement data (the voltage of the grid node i at time t) The power flow of the line between the grid nodes i and j at time t ), weather forecast (wind speed forecast value Light intensity prediction ) and equipment status (the available capacity of generator g at time t The state of charge of the energy storage device e at time t ).

[0050] Then, the above data is standardized:

[0051]

[0052] Among them, μ X is the data mean, σ X is the standard deviation of the data.

[0053] S102, extracting spatiotemporal features associated with power grid topology based on the real-time measurement data;

[0054] The three-dimensional tensor Input the spatio-temporal convolutional network (STCN) to extract the spatio-temporal features of the three-dimensional tensor D.

[0055] Wherein, N is the number of the grid nodes in the power system, T_in is the input time window length, and F is the characteristic dimension of the measurement data of the grid node.

[0056] A. Spatial Convolution, specifically a graph convolution network (GCN) operation based on power grid topology; used to capture power grid topology correlations, improve cross-region coordination capabilities, and reduce command conflicts:

[0057]

[0058] Among them, H (l-1) Represents the output feature matrix of the l-1 layer, H 0 is a three-dimensional tensor D; is the adjacency matrix with self-loops added (A is the adjacency matrix based on the power grid topology, and I_N is the identity matrix); is the degree matrix, the diagonal elements

[0059] is the trainable weight matrix, b spa is the bias term, σ represents the nonlinear activation function, is the output spatial feature.

[0060] By calculation The adjacency matrix can be symmetrically normalized to avoid gradient explosion. The normalized adjacency matrix is ​​compared with the input feature matrix H (l-1) Multiplying together can aggregate the grid node information of neighbors.

[0061] B. Temporal Convolution: This is used to expand the temporal receptive field, enhance adaptability to new energy fluctuations, and reduce evaluation lag to minutes.

[0062]

[0063] Among them, d is the dilation rate of the void convolution, which is used to control the size of the receptive field; W temp is the temporal convolution kernel weight, DilatedConv() is the hole convolution function, is the output spatiotemporal joint feature.

[0064] The total number of layers in the spatiotemporal convolutional network is L, where l is the current layer index. Each layer performs spatial convolution → temporal convolution → residual connection in sequence. The residual connection is calculated as follows:

[0065] H (l) =f(H (l-1) , W (l) )+H (l-1)

[0066] Among them, f() represents the above-mentioned spatial convolution and temporal convolution operations.

[0067] Grid measurement data (such as voltage and power flow) contains both low-frequency global features (such as regional load levels) and high-frequency local features (such as renewable energy fluctuations). The residual mechanism allows the network to retain key information in the original input (such as the grid node voltage baseline), avoiding information loss caused by multi-layer nonlinear transformations.

[0068] S103. Calculating new energy output and equipment availability based on the weather forecast data and equipment status data;

[0069] After temporally aligning the meteorological data with the equipment status, the features of the two types of data are first extracted.

[0070] A. Calculate equivalent new energy output based on meteorological data:

[0071]

[0072] Where f is a function based on the wind turbine / photovoltaic characteristic curve, such as:

[0073]

[0074] Among them, v_cut-in, v_cut-out, and v_rated represent the cut-in wind speed, cut-out wind speed, and rated wind speed, respectively; ρ, C_p, and A represent the air density, wind energy utilization coefficient, and blade swept area, respectively.

[0075]

[0076] Among them, η, A pv 、T amb represent the photoelectric conversion efficiency, photovoltaic panel area and ambient temperature respectively.

[0077] B. Calculate equipment availability based on equipment status:

[0078]

[0079] Among them, C g,max is the maximum capacity of generator g.

[0080] Then map it through the fully connected layer to get the feature F meta , feature F meta Used to introduce external influencing factors (weather / equipment) to reduce the error in regulating capacity prediction:

[0081]

[0082] Among them, ReLU is the activation function, W meta is the weight matrix of the fully connected layer, b meta is the bias term of the fully connected layer.

[0083] The feature F meta and spatiotemporal characteristics Splicing to obtain fusion features:

[0084]

[0085] Among them, d embed Represents the embedding dimension. The original feature dimension 3 is transformed through the fully connected layer Upgrade to d embed Dimension (such as 64 dimensions).

[0086] Then calculate through Multilayer Perceptron (MLP):

[0087]

[0088] Then, the MLP output is converted into physical dimensions, and the output range is constrained by the activation function to ensure the feasibility of the optimization model and the instruction feasibility rate:

[0089]

[0090] Among them, C i,nax is the maximum adjustable capacity of the grid node i, R ibase is the benchmark climbing rate, and round() is the rounding function.

[0091] S104: Generate a dynamic adjustment margin matrix based on the spatiotemporal characteristics, new energy output, and equipment availability;

[0092] According to the equipment utilization, the scheduling margin matrix is ​​obtained:

[0093]

[0094] in, represents the adjustable capacity of the grid node i at time t (MW), represents the ramp power of the grid node i (MW / min), Represents the sustainable adjustment time (min). The sigmoid function is used to limit the output to [0,1] and then multiply it by the maximum capacity of the device C. i,max ; The softplus function is used to ensure that the climbing rate is non-negative, R i,base is the reference value (such as 10MW / min); round(exp()) is the exponential + rounding function, which is used to discretize the duration into integer minutes.

[0095] The physical topology and dynamic characteristics of the power grid are captured through spatiotemporal convolutional networks to improve the assessment accuracy of the regulation margin; the "assessment lag" problem is solved through minute-level updates (rather than the traditional hourly level); the meteorological fusion mechanism enhances the adaptability to new energy fluctuations and improves the new energy absorption capacity.

[0096] S105. Predicting a quantile map of short-term flexibility demand based on the dynamic adjustment margin matrix;

[0097] Based on historical transaction data, new energy output forecasts and load forecast data, the demand forecast model is used to output a 15-minute spatiotemporal distribution map of flexibility demand.

[0098] Construct an Attention-LSTM model as a demand forecasting model. The structure of the demand forecasting model is as follows:

[0099] A. LSTM layer: h t =LSTM(x t ,h t-1 )

[0100] Among them, input Contains historical transaction data New Energy Forecast and load forecasting h t is the hidden state of LSTM at time step t.

[0101] B. Dual Attention Mechanism: 1. Temporal Attention:

[0102]

[0103]

[0104] in, is the temporal attention weight at time step t, W Q 、W K is the learnable query and key matrix, d k is the temporal attention dimension (usually 64), and H = [h1,h2,...,hT] is the concatenation of all time-step hidden states. T is the temporal context vector.

[0105] The temporal attention mechanism calculates the importance weights of different time steps to identify key fluctuation periods (such as the 15-minute window when photovoltaic output drops sharply) and assigns higher weights to these periods. Specifically, the model considers the hidden state at the current moment (Query = W Q ·h t ) and the hidden state of all historical moments (Key=W K H) performs similarity calculations (i.e., the above formula). If the pattern of a certain historical period is highly correlated with the current forecast demand (e.g., a similar PV drop occurred in the past), its similarity score will be higher. The similarity is then converted into probability weights using the softmax function.

[0106] In scenarios with high penetration of new energy, the fluctuation of photovoltaic output caused by cloud movement will form obvious spikes in the time dimension. Temporal attention automatically captures this mutation pattern and calculates the context vector c. T Higher weights are given to these periods so that the model pays more attention to these key fluctuations when predicting.

[0107] Spatial Attention:

[0108]

[0109] in, is the spatial attention weight, h i is the eigenvector of the grid node i, H S is the characteristic matrix of all the grid nodes, W Q '、W K ' is the spatial attention-specific weight. c S is the spatial context vector, d' k is the spatial attention dimension

[0110] Spatial attention is used to capture inter-regional demand correlations (such as the supply and demand coupling between load centers and new energy bases).

[0111] Generate context vector c:

[0112] c=W c [c T ||c S ]+b c

[0113] Where || is the vector concatenation operation, W c is the fusion weight matrix, b c is the fusion bias term.

[0114] The context vector c is the result of comprehensive spatiotemporal attention and represents the global key information.

[0115] C. Output layer:

[0116]

[0117] Used to output the spatiotemporal distribution map of flexibility demand in the next 15 minutes, N is the number of nodes in the power grid, T is the length of the time window, and Q is the number of quantiles. In statistics, the number of quantiles refers to the number of values ​​at a specific quantile position after a set of data is arranged in order of size.

[0118] For example, the 0.1 / 0.5 (i.e., median) / 0.9 quantile values ​​of the predicted demand of the grid node 1 in the three time periods within the time window can be expressed as follows:

[0119] The grid node 1:

[0120] [Time period 9:00-9:05; [2.1MW, 3.3MW, 4.8MW], / / The demand is less than 2.1MW 10% of the time, less than 3.3MW 50% of the time, and less than 4.8MW 90% of the time.

[0121] Time period 9:05-9:10; [2.4MW, 3.6MW, 5.1MW];

[0122] Time period 9:10-9:15; [2.7MW, 4.0MW, 5.5MW]].

[0123] The spatiotemporal distribution map clarifies the differences in demand between regions and provides input for cross-regional optimization.

[0124] Training strategy, using quantile loss function to enhance prediction robustness:

[0125]

[0126] Among them, τ is the target quantile value (such as 0.1, 0.5, 0.9), y i,t is the actual demand of the grid node i at time t, is the quantile demand value predicted by the model, and Λ is the quantile set (usually 5-9 quantiles).

[0127] 0.1 percentile: predicted demand lower limit (conservative estimate, used to ensure minimum adjustment capacity);

[0128] 0.5 quantile: median forecast (benchmark scheduling scheme);

[0129] 0.9 percentile: predicted upper limit of demand (to guard against unexpected fluctuations in new energy).

[0130] The quantile loss function can improve the prediction reliability in extreme scenarios and improve resource utilization efficiency.

[0131] Uncertainty in power demand forecasting primarily stems from renewable energy fluctuations and load randomness. Temporal attention can identify similar historical fluctuation patterns (such as the periodic drop in PV output in the afternoon) and enhance feature learning during these periods. Spatial attention can capture inter-regional chain reactions (for example, when wind power in Area A plummets, Area B needs to increase reserve capacity), improving cross-regional coordination accuracy. By combining forecasts at different quantiles, a demand fluctuation range is formed (for example, [50MW, 80MW, 110MW] corresponding to quantiles 0.1, 0.5, and 0.9), providing a safety margin for dispatchers. Different penalties are then applied for overestimation and underestimation. For example, if the quantile τ = 0.9 (the upper limit prediction), the model prioritizes underestimation and insufficient reserve capacity.

[0132] By combining spatiotemporal attention with quantiles, the uncertainty problem brought by new energy to the power system can be solved.

[0133] S106. Decomposing the global optimization problem into regional sub-problems according to the quantile map;

[0136]

[0137] in, is the regulation cost coefficient of the grid node i, is the regulation power of the grid node i, λ is the regulation smoothness weight, To adjust the smoothing term, p t The power vector represents the power of all grid nodes. The smoothing term is the squared L2 norm of the power change vectors of all grid nodes at adjacent moments. Specifically, each component of the power change vector (the power change of each grid node) is squared and summed. The smoothing term is used to limit the power change amplitude between adjacent moments (e.g., a 5-minute interval) to avoid frequent device adjustments.

[0144] This constraint ensures that once the grid node i is activated In the subsequent At least T in minutes min This constraint avoids frequent startup and shutdown of equipment (such as gas turbines), thus extending the life of the equipment.
