Embodiment

[0140] This example applies clean energy power planning in stages considering wind and solar uncertainties and thermal power unit withdrawals to the IEEE RTS79 system to realize clean energy power planning in four stages, focusing on considering wind and solar uncertainties and thermal power unit retirements , taking into account factors such as hydropower participation in mediation constraints, water abandonment costs, and power balance. The data on the RTS79 system includes: the number of thermal power plants is 6, the total number is 24, and the total capacity is 2500MW. The total hydropower capacity of the first stage: 3540MW; the total hydropower capacity of the second stage: 4980MW; the total hydropower capacity of the second stage: 5880MW; the total hydropower capacity of the second stage: 7740MW; the total hydropower capacity of the second stage: 9600MW . The load of each stage increases at a growth rate of 20%.

Abstract

The invention discloses a clean energy power planning method based on Wasserstein distance and distribution robust optimization, and relates to the technical field of power system planning. The methodcomprises the following steps: S1, constructing a wind-photovoltaic power output uncertainty set based on Wasserstein distance; S2: establishing a power planning model under distributed robust optimization; S3, solving by bringing the wind-photovoltaic power output uncertainty set into the power planning model under distributed robust optimization to obtain a clean energy power planning scheme. Compared with a traditional method, the method of the invention has lower conservatism of the uncertainty set, has strong ability to adapt to complex and changeable operating environments, and can be adopted for effective solution.

Description

technical field [0001] The invention relates to the technical field of power system planning, in particular to a clean energy power planning method based on Wasserstein distance and distribution robust optimization. Background technique [0002] On the basis of traditional power grid planning, existing studies have established a variety of power grid planning models for different planning needs. Most of the models only involve a phased planning, lacking an overall layout for long-term planning. Coupled with the large-scale access of renewable energy to the grid, the uncertainty of grid planning is gradually increasing, and the planning scheme obtained only by relying on the power balance constraints under a given reserve rate cannot meet the requirements of stable operation of the grid. [0003] At present, many studies have considered the operation of the grid in grid planning. The literature "Fan Zhicheng, Zhu Junpeng, Yuan Yue, et al. Distributed power planning model and ...
