考虑新能源参数调整的短路电流优化控制方法
An optimal short-circuit current control method considering new energy parameter adjustment
摘要
Abstract
With the expansion of power grids and the increase in power sources,excessive short-circuit current in power systems has become increasingly severe.Conventional short-circuit current control measures are increasingly inadequate to meet the requirements.To mitigate the impact of short-circuit current control on the grid,this paper proposes a coordinated optimal control method that comprehensively considers various measures,including renew-able energy parameter adjustment,line outages,and unit decommitment.In view of the effects of control measures on grid power supply capacity and reactive voltage,multiple optimization objectives are designed,and a mixed-integer programming model incorporating various constraints is constructed.The control model is linearized,and a two-stage solution strategy is proposed,prioritizing conventional control measures supplemented by new energy pa-rameter adjustment,to resolve short-circuit current exceedances and enhance the safety margin for short-circuit cur-rent operation.The effectiveness of the proposed short-circuit current control model and solution method is verified through a case study on a provincial-level regional power grid.关键词
