Renewable energy and thermal power generation coupling system based on improved particle swarm reactive power optimization control
摘要
Abstract
This thesis constructs a coupling system inactive adjustment model for system voltage output of wind power fluctuations in renewable energy and thermal power generation coupling systems,and constructing coupling system reactive modulation models,on the basis of considering communication delays,The voltage deviation is quantified index to analyze the effect of reactive power control on voltage stability in coupling system.A coupling system bilateral reactive control optimization strategy for fusion SVG and wind turbines as reactive modulated resources is proposed.The upper layer is based on SVG as an inactive adjustment device,and the system's overall power factor optimization model is constructed by the respective node voltage deviation.The lower layer is a node having a large voltage deviation.The wind turbine near the node is used as an inactive adjustment device.The system voltage deviation is optimal,and the wind turbine reactive optimization model is constructed,and the algorithm combined with Ybus and LinWPSO is used.Solve the optimization model and derive the wind power unit reactive reference value.The case simulation results show that the two-layer reactive policies mentioned in this paper make full exertion of the power-modulated potential of the wind and motor sets,which can take care of the voltage fluctuations and web damage of the coupling system,and reduce the disturbance of the renewable energy power fluctuations on the coupling system,improve coupling the voltage stability of the system.关键词
