Research on Frequency and Voltage Control Strategy for New Energy Collection and Delivery Based on Digital Twin

The construction of security and stability control system based on digital twin consists of infrastructure, information exchange platform and application scenarios. By establishing the digital twin model, the frequency and voltage stability control strategy of new energy collection and delivery can be established. The complement character of multi coupling energy and the output uncertainty of new energy generation will be analyzed in the virtual space. On the basis of simulation and calculation with the virtual model of digital twin, the risk assessment model and the quantitative calculation of risk values will be realized for the new energy collection and delivery. Through the calculation and comparative analysis of the effect and adaptability, the optimal security and stability regulation scheme can be selected to decrease the risk level and reduce the power loss. The sustainable operation of new energy can be achieved with the virtual model of digital twin for security and stability regulation system.
