If the suppose is incorrect, the designed dispatching chart form will be abandoned, and the algorithm will search the optimal solution by its own strength.
The fundamental form of the dispatching chart can be made through analysis on reservoir runoff distribution and characteristics of the designed dispatching chart form...
②通过对水库径流分布、设计调度图形式自身特点的分析可以给出调度图的基本形式。
The analysis indicates that the line shape tendency of the designed dispatching chart reflects the runoff distribution trend as a dispatching chart of high guarantee ratio.
分析说明了设计调度图的线形走势基本反映了径流的分布趋势,同时是一种以高保证率为主调度图形式。
The characteristics of this method is that it considers the experiential suppose indirectly, and needs to rely on the optimization algorithm itself to break through limitations of the designed dispatching chart.
该方法的特点是:是一种间接考虑经验性假设的方法,需要依靠优化算法自身来突破设计调度图的局限,
Therefore, though making of the designed dispatching chart is extremely experiential, it can guarantee a good dispatching efficiency, because the runoff distribution characteristics and the general conclusions of reservoir optimization dispatching are adapted.
The characteristics of this method is that experiential suppose is presented by combining runoff analysis with the designed dispatching chart form, which is. directly reflected to the encoding and algorithm design process.
Thereby the information of the designed dispatching chart can be digitized and btaken as an individual of the initial population in the optimization algorithm.
因此可以将设计调度图的信息数字化,作为优化算法初始种群中的一个个体。
Analyze the reservoir designed dispatching chart, the distribution of incoming runoff, the optimal dispatching process in the typical years, and identifye key inflection points.
1、分析水库设计调度图、入库径流分布、典型年最优化调度过程等信息,确定关键拐点。
According to the principle of the designed dispatching chart, the firm output area reflects the safe running mode of the power system in the hydrological condition of the design guarantee rate, while the increasing output area and the decreasing output area are more fit for the uncertainty of the incoming water in the high flow year and the low flow year.
The designed dispatching chart and the hydrograph (average, the maximum, the minimum) of every ten days over the years are shown as Fig. 2, from which it can be seen that the line shape trend of the upper and the lower dispatching lines is consistent with the average hydrograph of every ten days over the years.
