Embodiment

[0030] Such as figure 1 As shown, a grid peak regulation method considering external power receiving includes the following steps:

[0031] 1) Obtain the internal power structure and external power receiving mode of the power grid to be peak-shaving;

[0032] 2) According to the historical load information and economic development factors of the power grid to be peak-shaving, predict its power load during the peak-shaving period;

[0033] 3) Consider the internal power supply structure and external power receiving mode, formulate a peak-shaving balance strategy, and combine peak-shaving with internal and external power supplies.

[0034] Shanghai Power Grid is an important part of the East China Power Grid. It is located at the receiving end of the East China Power Grid and is the load center with the highest load density in East China and even the whole country. Shanghai Power Grid is an urban-rural integrated power grid, and its power supply covers the whole of Shanghai. ...

Abstract

The invention relates to a peak adjusting method of the electrical network by taking external power reception into consideration. The method comprises the following step that 1) the internal power structure and the external power reception manner of the electrical network whose peak is to be adjusted are obtained; 2) the power load of the electrical network within the peak adjusting period is predicted according to historical load information of the electrical network; and 3) a balanced peak adjusting strategy is made by considering the internal power structure, the external power reception manner as well as the power load state in the peak adjusting period, and internal and external power supplies are combined to adjust the peak. Compared with the prior art, the method has the advantages including that the peak adjusting effect is good.

Description

technical field [0001] The invention relates to a peak regulation method, in particular to a power grid peak regulation method considering external power receiving. Background technique [0002] With the strong support of relevant state departments, the tension in Shanghai's power supply has been significantly eased since the "12th Five-Year Plan", but at the same time, the external environment for Shanghai's power development is undergoing profound changes. With the favorable conditions of slowing down the growth rate of power demand in economic transformation, it also faces challenges such as higher and higher requirements for power supply security and cleanliness, increasing contradictions in peak-valley adjustment, and increasingly difficult implementation of power projects. [0003] Shanghai Power Grid is a typical receiving-end power grid. The proportion of external power has reached about half of the maximum load. The external power is mainly clean energy such as Sout...
