摘要:
      分布式潮流控制器能够灵活地提升现有线路的输电能力,从而降低系统运行成本,但该设备的引入会增加电力系统最优潮流问题的复杂度与非凸程度。本文针对分布式潮流控制器的结构及原理进行了分析,提出一种简化的稳态功率模型,并考虑到装置运行时各串联单元自身容量限制,给出实际电网中分布式潮流控制器线路的潮流可行域。基于此,采用对初值选取不敏感的半定规划法建立含分布式潮流控制器的系统最优潮流模型,并选用原对偶内点法进行求解。算例测试结果表明,所提方法能有效解决含分布式潮流控制器的系统潮流优化问题。
Abstract:
      Distributed power flow controller(DPFC) can flexibly improve the transmission capacity of existing lines and thus reduce operating cost of power system, however, the introduction of DPFC increases difficulties and non-convexity of traditional optimal power flow(OPF) problem. A simplified steady-state power model of DPFC is proposed based on its structure and working principle. The feasible region power of flow for line with DPFC in actual power grid is given considering the capacity of series unit of device in operation. On this basis, the semi-definite programming(SDP) method which is insensitive to the initial value is extended to establish the optimal model of system with DPFC, then the primal dual interior point method is used to solve the OPF problem. The test results show that the proposed method can solve the OPF problem with DPFC.
