摘要
为提高系统配置低电价可中断负荷(interruptible load with low price,ILL)的经济性,针对ILL与高赔偿可中断负荷的经济互补特性,运用协调优化理念,从风险管理角度建立了市场环境下优化ILL配置的数学模型,提出了基于代价对参数的灵敏度来指导优化方向的寻优算法,并针对容量事故集对ILL的最优配置进行风险决策。仿真结果表明,ILL的配置过高或过低都不合适,而应存在一个最优值。
To improve the economy of configuring interruptible load with low price (ILL) in power system, according to the economic complement property between ILL and interruptible load with high compensation and using the idea of coordinative optimization, based on risk management a mathematical model of optimizing the configuration of ILL in market environment is built and an optimization algorithm based on the sensitivity of total compensation cost to parameters that guides the optimization direction is proposed; and the risk-decision for the optimal configuration of ILL aiming at all capacity faults is conducted. Simulation results show that either too high or too low configuration of ILL is unsuitable and an optimal configuration should exist.
