考虑新能源参数调整的短路电流优化控制方法OA
An optimal short-circuit current control method considering new energy parameter adjustment
随着电网规模的扩大和电源数目的增加,电力系统短路电流超标问题日益严重,常规短路电流控制措施越来越难以满足短路电流控制的要求.为了降低短路电流控制对电网产生的影响,提出了一种综合考虑新能源参数调整、停运线路和机组等多种控制措施的短路电流协调优化控制方法.考虑到控制措施对电网供电能力以及无功电压的影响,设计多优化目标,构建考虑多种约束条件的混合整数规划模型.对控制模型进行线性化处理,提出两阶段求解策略,以常规控制措施为主,新能源参数调整控制措施为辅,解决短路电流超标问题并提升短路电流安全运行裕度.通过省级区域电网算例仿真,验证了所提短路电流控制模型和求解方法的有效性.
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.
