[0064] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0065] Embodiment 1:

[0066] This embodiment is aimed at Figure 1 The regional network model diagram shown in FIG. 1 (including four power consumption areas, namely, industrial park, residential area 1, residential area 2 and residential area 3) implements a mobile energy storage auxiliary scheduling method based on multi-regional power demand, such as Figure 2 As shown, the specific steps are as follows:

[0067] 1. In the case of a power outage, obtain the historical power consumption data D of the four power consumption areas recorded in the power grid system ind={d ind,1 ,…,d ind,L}、

[0068] 2. The following information interaction is performed on the historical power consumption sequence of each power consumption area through the self-attention mechanism:

[0069]

[0070] In the above formula, They are the feature mapping results of the historical electricity consumption series of the industrial park, residential area 1, residential area 2, and residential area 3. Embedding is an independent feature mapping operation. They are the lth group of data in the historical electricity consumption series of the industrial park, residential area 1, residential area 2 and residential area 3 respectively, and L is the length of the historical electricity consumption series.

[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, H i After layer normalization Mean is the average value, var is the variance;

[0074] 4. Perform fully connected feature encoding in the feedforward network and predict the power 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} is the power consumption prediction result of the ith power consumption area with a sequence length of m, and Projection is a mapping operation.

[0077] 5. Combined with the regional network model, the overall benefit model of the power supply process is derived.

[0078] The electricity price in the commercial area is P 1 , the electricity price in the residential area is P 2 The mobile energy storage vehicle is a pure electric vehicle, and the power consumption per kilometer is E. However, the energy storage loss during the movement is not taken into account. The speed of the mobile energy storage vehicle on the trunk line is v 1 , the speed on the branch line is v 2The expenditure of using mobile vehicles to supply electricity to these four areas consists of two parts, namely the electric energy used by the electric vehicle during driving and the loss of the energy storage vehicle, which is expressed as follows:

[0079] consume=2·(E+Δ)·dis

[0080] In the above formula, consume is the overall expenditure, Δ is the loss of the energy storage vehicle per kilometer, and dis is the one-way distance traveled by the mobile energy storage vehicle.

[0081] The revenue is the electricity charges collected in these four areas, expressed as:

[0082]

[0083] In the above formula, Y ind , are the electricity consumption of the commercial area and the i-th residential area respectively.

[0084] Therefore, the overall benefits of the mobile energy storage vehicle in the power supply process are expressed as:

[0085]

[0086] In the above formula, P ini The cost of electricity to charge the charging station.

[0087] 6. Under the premise of ensuring the electricity demand in each region, the following mobile energy storage vehicle optimization scheduling model is constructed:

[0088]

[0089] In the above formula, z is the scheduling scheme, N i is the number of mobile energy storage vehicles in the i-th power consumption area, and track is the driving route of the mobile energy storage vehicle.

[0090] 7. Convert the above scheduling model into an energy storage vehicle quantity optimization model and a path planning model, which are:

[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 converted into an equivalent constraint. Therefore, the optimal solution of the optimization model (P1) can be directly obtained, that is, N s =Y s / Aviable, Aviable is the power supply of each mobile energy storage vehicle. The energy storage vehicle driving route of the optimization model (P2) still needs further analysis, so the optimization model (OP) can be simplified as follows:

[0093]

[0094] 8. Construct the equivalent Markov state transition process of the path planning model (P3):

[0095] max Q π (s,a;θ)=E[R 1 +γR 2 +…|S,A,π;θ]

[0096] In the above formula, Q π (s, a; θ) is the cumulative expected reward under path planning, s, a, θ are the state, action, and network parameters respectively, R is the reward under 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 formulated path planning strategy, γ is the attenuation coefficient, and E[·] is the expectation for x.

[0097] 9. Use the DDQN algorithm to iteratively solve the problem, and then obtain the path planning strategy π, which is the track in the objective function. The network selection and network 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 is the optimization target of the target network and the estimated network at time t, R t+1 is the reward value obtained after executing the action at time t+1, S t+1 is the state at time t+1, Q(S t+1 ,a;θ t ) is the Q value of the target network, θ t ,θ t ′ are the parameters of the target network and the estimated network at time t respectively.

[0101] In order to verify the effectiveness of the method of the present invention, the method of Example 1 is compared with the fixed driving method, and the overall benefits of the power supply process of the two methods are calculated respectively. The results are as follows: Figure 3 It can be seen that the overall benefit of the method of the present invention is significantly higher than that of the fixed driving method.

[0111] C. Perform fully connected feature encoding in the feedforward network and predict the power consumption of each power consumption area through projection layer mapping:
