Embodiment Construction
[0045] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0046] In the present invention, the power system refers to the power system on which the power market relies, generally (not limited to) the provincial power system, and the partition refers to the sub-power system in the power system, generally (not limited to) the municipal power system system. A power system consists of several partitions.
[0047] In this embodiment, every day is divided into 96 time periods; the historical load days of each partition and each substation are three days, that is, n=3; the power system has three partitions, namely, partition 1, partition 2 and partition 3; The partition contains several substations. In this embodiment, only a certain substation in each partition is counted, that is, substation 1 (belonging to partition 1), substation 2 (belonging to partition 2) and substation 3 (belonging to partition 3). ...

The invention relates to a method for predicting transformer substation load by applying public information of a power market. The method comprises the steps of obtaining the public information of the power market; calculating a load expected value of each time period in each partition day and a load expected value of each time period in the electric power system day; calculating a load expected value of each time period in each transformer substation day; solving the load distribution proportion of each partition in each time period; calculating the load of each partition in each time period; solving the ratio of the load expected value of each time period in each transformer substation day to the load expected value of each time period in the corresponding partition day, and obtaining the load distribution proportion of each time period of each transformer substation; and solving the load distribution proportion of each time period of each transformer substation and the load of the corresponding partition and time period to obtain the predicted load of each time period of the transformer substation. According to the invention, the load of each substation in each time period of the operation day can be predicted before the operation day, support is provided for analysis work of an electric power spot market, the problem of lack of load information of the substation in each time period is effectively solved, and the method has the characteristics of high reliability, simplicity and the like.
Description
technical field [0001] The invention belongs to the technical field of substations, and relates to substation load forecasting, in particular to a method for forecasting substation loads using public information in the electric power market. Background technique [0002] Under the background of the gradual deepening of the market-oriented reform of the electric power industry and the rapid development of the electric power spot market, effective market analysis has a great impact on market members' advantage in market competition. However, for members of a single market, they can only obtain part of the market's public information. Specifically, in terms of electricity load in the power system, market members can obtain the historical load of each substation and partition in the power system, and obtain the total load value of the power system predicted before the operation date through the power market information release system. However, it is impossible to directly obtai...
