构网型变流器的功率-相角直接控制策略
Power Phase-angle Direct Control for Grid-forming Converters
摘要
Abstract
With the increase in the proportion of new energy in the power system,the use of grid-forming converters is crucial for improving the stability of the power system.In grid-forming control strategies,due to the limitations of the power system,the frequency dynamic response control performance on the AC side of the converter becomes an important design factor.The grid-forming control strategy that simulates the synchronous generators model has been widely used.However,due to the different physical structures,the characteristics of grid-forming converters are not completely consistent with those of synchronous generators.Therefore,this paper designs a power phase-angle direct control strategy for grid-forming converters,and a direct control law between active power and phase angle and an indirect control law between active power and frequency are established,which improves the control flexibility of grid-forming converters for the frequency dynamic response process while keeping the control system structure simple.At the same time,this paper conducts a parametric analysis between control parameters and frequency dynamic responses,and carry out a tuning method for control parameters.The results show that under this method,by appropriately adjusting the control parameters,important indicators such as the maximum frequency deviation,inertial response time,and rate of change of frequency of the grid-forming converter can be flexibly adjusted,and the transient stability of the grid-forming converter can be improved.关键词
