摘要
将可用发电容量的取值范围划分为静态不充裕、动态风险充裕和动态充裕3个区间,分别定义静态充裕度和动态充裕度指标,并分析静态和动态容量扰动的影响。在由静态充裕度、动态充裕度及经济代价组成的三维空间中分析发电容量风险。将可中断负荷视为一种紧急备用容量资源,协调备用容量的发电侧决策与需求侧决策,计算最优风险不中断负荷。将发电成本、备用成本、限电损失及停电风险统一表达为货币形式,以协调可靠性与经济性。仿真结果表明了所提出方法的有效性。
The available generation capacity can be divided into three sections, i.e. static inadequacy, dynamic risk adequacy and dynamic adequacy. Margins of static adequacy and dynamic adequacy are defined respectively, the effects of static and dynamic disturbances could be quantitatively analyzed. Risks of generation capacity are dealt with in a 3-D space consisting of static adequacy margin, dynamic adequacy margin and cost. The risk optimized uninterruptible load can be estimated by treating interruptible loads as one kind of emergency generation reserve. Simulations show the validity of the presented method.
