摘要
研究了实时电力系统中输电阻塞管理的成本控制问题.针对同时开放发电侧和负荷侧的情形,引入阻塞率因子,建立了新的阻塞费用优化模型.基于minimax思想和模拟退火算法,将实时阻塞管理问题转化为最大输电阻塞时调整费用最小的非线性规划问题,得到了全局最优解.仿真结果表明,改进的优化模型可有效缩减和控制调整费用,所设计的算法简单可行且安全可靠.
This paper investigates the cost control problem of congestion management model in the real-time power systems.An improved optimal congestion cost model is built by introducing the congestion factor in dealing with the cases of opening the generator side and load side simultaneously.The problem of real-time congestion management is transformed to a nonlinear programming problem.While the transmission congestion is maximum and the adjustment cost is minimum based on the minimax idea and simulated annealing algorithm,and the global optimal solution is obtained.Simulation results show that the improved optimal model can obviously reduce the adjustment cost,and the designed algorithm is safe and easy to implement.
