Abstract

Focusing on the problem that the current identification methods rely on the transient data under the large disturbance of the system, which cannot meet the online analysis requirements of the new power system, an online parameter estimation method for distributed photovoltaic composite load model based on deep reinforcement learning algorithm TD3 is proposed in this paper. The model is simplified based on the mechanism, and the global sensitivity of the parameters is calculated under random small disturbance, based on which the discernible parameters that have great influence on the dynamic characteristics of load model are selected. Using the difference between dynamic response with different parameters under small disturbance, the TD3 algorithm is used to identify the model parameters, the interface function between the algorithm and the simulation system is constructed, and the training scheme that can make the algorithm meet the needs of multi-scene identification is designed. Finally, the feasibility of the proposed method is verified in various random small disturbance scenarios based on EPRI-36 node system in PSASP.
