直流配电网功率控制策略与电压波动研究
Research on Power Flow Control and the Voltage Fluctuation Characteristics of DC Distribution Networks Based on Different Control Strategies
摘要
Abstract
The operation characteristics of DC power networks are determined by the control systems and the control strategy would impact on the power distribution and voltage stability of the system significantly.The dynamic model and control system of DC power distribution network was established for researching on the voltage fluctuation problems.The index of unbalanced degree of voltage profile was put forward to evaluate the equilibrium degree of voltage fluctuation.In the operating conditions of the integration and trip-off of the wind power, the voltage fluctuation characteristics of the distribution network were simulated and analyzed based on master slave and droop control strategies.The results show that the master-slave control strategy has better voltage regulation ability, but the droop control strategy has lower loss of the system.The trade-off and optimization should be made between the two control modes according on power supply and demand.关键词
