Abstract
Description
Technical Field
[0001] This invention belongs to the field of power grid collaborative control technology, and specifically relates to a method and device for dynamic collaborative control of voltage between a virtual power plant and a distribution network. Background Technology
[0002] With the current acceleration of energy transition, virtual power plants, by aggregating distributed energy resources (DERs) and connecting them to urban distribution networks, have become an important development direction for new power systems. However, the randomness and intermittent nature of high-proportion DERs presents several technical bottlenecks for distribution network voltage control: On the one hand, DERs and resources such as energy storage and controllable loads have significant differences in response speed over time scales, and traditional hierarchical control frameworks rely on fixed priority allocation, making it difficult to dynamically coordinate the regulation capabilities of different resources; on the other hand, the fusion analysis of multi-source heterogeneous data such as meteorological data, grid topology status, and DER output still relies on manual feature engineering, and existing models still struggle to capture complex spatiotemporal coupling relationships; furthermore, while advanced machine learning algorithms can improve control real-time performance, their black-box decision-making model remains fundamentally contradictory to the power system's requirements for compliance and interpretability of control strategies.
[0003] Currently, traditional technical approaches have significant shortcomings in addressing the aforementioned challenges: hierarchical control strategies based on fixed rules cannot adapt to the dynamic changes in DERs output, often leading to voltage regulation lag; data analysis models relying on manual feature engineering have limited generalization capabilities for complex scenarios, affecting voltage prediction accuracy; and algorithms such as deep reinforcement learning, due to a lack of interpretability support, pose a risk of violating operating procedures in practical engineering applications. Summary of the Invention
[0004] To address the aforementioned technical challenges, this invention proposes a method and device for dynamic coordinated voltage control of a virtual power plant and distribution network. Breaking through the limitations of fixed logic in traditional voltage control, it achieves adaptive response to uncertainties in distributed energy resources, providing an intelligent solution for voltage stability in distribution networks with high-proportion renewable energy integration scenarios.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A method for dynamic coordinated control of voltage in a virtual power plant and distribution network includes the following steps: A hybrid dataset is constructed by acquiring multi-source heterogeneous data for collaborative control, and the hybrid dataset is mapped to quantum state space for feature extraction; the multi-source heterogeneous data includes distributed energy output data, distribution network topology status, and meteorological monitoring data. An improved Transformer-XL model is used to fuse quantum features, satellite cloud images, and voltage waveform data, and quantum probabilistic modeling is employed. Based on the principle of quantum superposition, DERs output scenarios are generated, and the voltage over-limit probability amplitude of each node is quantified through quantum Monte Carlo tree search to generate a heat map of distribution network risks. A hierarchical control decision-making mechanism is constructed. Specifically, the reactive power compensation problem of energy storage is modeled as a quantum optimization problem to generate real-time adjustment commands for reactive power of energy storage. Based on the risk heat map and topology characteristics of the distribution network, the topology characteristics of the distribution network are extracted through an interpretable graph reasoning network. The constraints of the distribution network operation procedure are represented by linear time-series logic to generate a controllable load dispatching strategy. Based on the day-ahead DERs output prediction, the energy aggregation strategy is optimized to generate interpretable dispatching rules. The hierarchical control decision is executed, and then a causal logic chain of voltage over-limit events is generated through an invariant graph inference network. The contribution of features to the control decision is quantified using SHAP values, and the model parameters are rapidly iteratively optimized by combining a meta-learning mechanism.

[0046] Figure 7 This is a bar chart comparing the traditional scheme and the quantum-dynamic architecture scheme in terms of three quantitative indicators: voltage over-limit probability, new energy absorption rate, and mean control error under the uncertainty scenario proposed in Embodiment 1 of this invention; from Figure 7 As can be seen, under different scenarios such as typhoons, severe convection, normal weather, and continuous rain, the quantum-dynamic architecture scheme significantly reduces the voltage exceedance probability (e.g., from 0.72 to 0.12 in typhoon scenarios), greatly improves the renewable energy absorption rate (e.g., from 0.62 to 0.88 in normal weather scenarios), and significantly reduces the mean control error (e.g., from 15.60 to 2.10 in typhoon scenarios) compared to the traditional scheme. This demonstrates that the risk assessment technology based on quantum probability modeling and the adaptive optimization mechanism of the dynamic neural architecture work synergistically to accurately quantify the uncertainty of distributed energy output. This enhances the distribution network's resistance to renewable energy fluctuations in both extreme and normal scenarios, effectively improves renewable energy absorption efficiency, and significantly enhances the system's robustness under uncertain scenarios.
