[0056] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0057] 1. This invention discloses a mobile energy storage-assisted scheduling method based on multi-regional electricity demand. First, it predicts the electricity consumption of multiple electricity-consuming regions in an emergency scenario. Then, based on the electricity consumption of these regions, it constructs an optimized scheduling model for mobile energy storage vehicles, aiming to maximize the overall benefit of the power supply process. Finally, it solves the optimized scheduling model to obtain an optimized scheduling scheme for mobile energy storage vehicles. This method starts from the perspective of actual regional electricity demand, optimizing the scheduling scheme of mobile energy storage vehicles while ensuring the electricity demand of each region.

[0064] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0065] Example 1:
[0066] This embodiment is for Figure 1 The regional network model diagram shown (containing four power consumption areas, namely industrial park, residential area 1, residential area 2, and residential area 3) implements a mobile energy storage-assisted dispatch method based on multi-area power demand, such as... Figure 2 As shown, the specific steps are as follows:
[0067] 1. In a power outage scenario, obtain historical electricity consumption data D for four electricity consumption areas recorded in the power grid system. ind ={d ind,1 ,…,d ind,L}、
[0068] 2. Using a self-attention mechanism, the historical electricity consumption sequences of each electricity consumption area are exchanged as follows:
[0069]
[0070] In the above formula, These are the feature mapping results for historical electricity consumption sequences of the industrial park, residential area 1, residential area 2, and residential area 3, respectively. Embedding is an independent feature mapping operation. These are the l-th data sets in the historical electricity consumption sequences of the industrial park, residential area 1, residential area 2, and residential area 3, respectively, where L is the length of the historical electricity consumption sequence.
[0071] 3. Use layer normalization to unify the feature channel distribution of different variables:
[0072]
[0073] In the above formula, LayerNorm is the layer normalization operation, and H i After layer normalization operation Mean is the average value, and var is the variance.
[0074] 4. Perform fully connected feature encoding in the feedforward network, and predict the electricity consumption of each power consumption area through projection layer mapping:
[0075] Y i {L:L+m} =Projection(H i )
[0076] In the above formula, Y i {L:L+m} This represents the predicted electricity consumption result for the i-th electricity consumption area with a sequence length of m. Projection is a mapping operation.
[0077] 5. Based on the regional network model, derive the overall revenue model of the power supply process.
[0078] The electricity price in the commercial area is P1, and the electricity price in the residential area is P2. The mobile energy storage vehicle is a pure electric vehicle, and its electricity consumption per kilometer is E. However, energy storage losses during the movement are negligible. The speed of the mobile energy storage vehicle on the main line is v1, and its speed on the branch lines is v2. The expenditure for supplying electricity to these four areas using the mobile vehicle includes two parts: the electricity used by the electric vehicle during its movement and the losses of the energy storage vehicle, as shown below:
[0079] consume = 2·(E+Δ)·dis
[0080] In the above formula, consume represents the total expenditure, Δ represents the loss per kilometer of the energy storage vehicle, and dis represents the one-way distance traveled by the mobile energy storage vehicle.
[0081] The revenue breakdown is the electricity fees collected in these four areas, expressed as follows:
[0082]
[0083] In the above formula, Y ind , These represent the electricity consumption of the commercial area and the i-th residential area, respectively.
[0084] Therefore, the overall benefit of the mobile energy storage vehicle in the process of providing power is expressed as follows:
[0085]
[0086] In the above formula, P ini The cost of electricity for charging stations.
[0087] 6. To ensure the electricity demand of each region, construct the following optimized scheduling model for mobile energy storage vehicles:
[0088]
[0089] In the above formula, z represents the scheduling scheme, and N i Let represent the number of mobile energy storage vehicles in the i-th power consumption area, and track represent the travel route of the mobile energy storage vehicles.
[0090] 7. The above scheduling model is transformed into an energy storage vehicle quantity optimization model and a route planning model, which are as follows:
[0091]
[0092] Since the number of energy storage vehicles N only meets the electricity demand of the industrial park, residential area 1, residential area 2, and residential area 3, this part can be transformed into an equivalent constraint. Therefore, the optimal solution of the optimization model (P1) can be directly obtained, i.e., N. s =Y s / Aviable, where Aviable is the available power of each mobile energy storage vehicle. The energy storage vehicle travel routes in the optimization model (P2) still require further analysis; therefore, the optimization model (OP) can be simplified to:
[0093]
[0094] 8. Construct the equivalent Markov state transition process for the path planning model (P3):
[0095] max Q π (s,a;θ)=E[R1+γR2+…|S,A,π;θ]
[0096] In the above formula, Q π(s,a;θ) represents the cumulative expected reward under path planning, where s, a, and θ are the state, action, and network parameters, respectively, R is the reward for each corresponding action, S and A are the state space and action space, respectively, the action space represents the choice at each intersection, including four actions: up, down, left, and right, π is the defined path planning strategy, γ is the decay coefficient, and E[·] is the expectation of x.
[0097] 9. The DDQN algorithm is used for iterative solution to obtain the path planning strategy π, i.e., track in the objective function. The network selection and update methods are as follows:
[0098] Y t Q =R t+1 +γQ(S t+1 ,argmaxQ(S t+1 ,a;θ t );θ t )
[0099] Y t DoubleQ =R t+1 +γQ(S t+1 ,argmaxQ(S t+1 ,a;θ t );θ t ′)
[0100] In the above formula, Y t Q Y t DoubleQ Let R be the target network at time t, and the optimization objective of the estimated network. t+1 S is the reward value obtained after performing the action at time t+1. t+1 Let Q(S) be the state at time t+1. t+1 ,a;θ t ) represents the Q-value of the target network, and θ represents the Q-value of the target network. t θ t ' and ' are the parameters of the target network and the estimated network at time t, respectively.
[0101] To verify the effectiveness of the method described in this invention, the method described in Example 1 was compared with the fixed-route method. The overall benefits of the power supply process for both methods were calculated, and the results are as follows: Figure 3 As shown, the overall benefits of the method described in this invention are significantly higher than those of the stationary driving method.
