Embodiment 2

[0244] Example 2, as a comparison, Example 2 uses the timing simulation method of the prior art to optimize the configuration of the microgrid, and the configuration results are shown in Table 2:

[0245] Table 2 Configuration results of timing simulation method

[0247]

Embodiment 3

[0248] Example 3, as a comparison, Example 3 adopts the typical daily method of the prior art to optimize the configuration of the microgrid, and the configuration results are shown in Table 3:

[0249] Table 2 Typical day method configuration results

[0250]

[0251] Comparing Table 1, Table 2 and Table 3, it can be seen that compared with the typical daily method in the prior art, the typical scene set based on clustering technology can better reflect the changing characteristics of wind and load data, and the configuration results of the typical scene method can Meet the actual operation requirements of the microgrid. Compared with the timing simulation method of the prior art, the typical scene set method effectively reduces the planning data, takes into account the calculation accuracy, and improves the economy of the microgrid's annual operation.

Description

technical field [0001] The invention relates to the electrical field, and is a wind / solar / storage / firewood micro-grid optimization configuration method that takes into account typical scenarios of differences in meteorological fluctuation characteristics, and is applied to distribution generation (DG) planning of micro-grids. Background technique [0002] As my country's energy and environmental issues become increasingly prominent, the construction of microgrids has received more and more attention. The development of micro-grids is conducive to promoting the local production and consumption of clean energy, and reducing the demand for external power in load centers. In the island mode of the microgrid, the distributed power generation (DG) including wind turbines, photovoltaic panels and diesel generators bears all the power load of the microgrid. Due to the intermittent and fluctuating nature of renewable energy, the microgrid only configures Distributed power generation...
