摘　　要：基于时间断面的无功/电压优化控制模型忽略了控制设备动作时间及2次优化控制期间的系统变化,因此不能准确反映优化控制效果。提出考虑过渡过程影响的多目标无功/电压优化控制模型,通过对过渡过程的智能分段和负荷变化方向的动态评估,并应用智能ε-支配域并行算法,能更精确地对电网有功损耗、控制设备动作引起的电压波动以及由于负荷变化所导致的的系统电压稳定负荷裕度变化量进行优化控制。通过IEEE30节点模型和一实际系统模型的仿真,验证了所提模型较传统无功/电压优化控制模型具有更好的优化控制能力。Conventional reactive power/voltage optimal control model based on time section ignores the operation time of control equipments and the system change between two optimal controls,which can not precisely reflect the optimization effect. A multi-objective reactive power/voltage optimal control model considering transition process is proposed,which intelligently sections the transition process,dynamically estimates the load change direction,and uses the intelligent e-domination parallel algorithm to more precisely carry out the optimal control of the grid active power loss,the voltage fluctuation caused by control equipment operation and the system voltage stability load margin change caused by load variation. The better performance of optimal control with proposed model is verified by the simulations for the IEEE 30-bus model and an actual system model.
