Embodiment

[0033] figure 1 It is a schematic diagram of the application of the capacity planning method for the construction of a wind-solar-storage-transmission hybrid power station.

[0034] Such as figure 1 As shown, in this embodiment, the power output models of wind turbines, photovoltaic modules, and energy conversion models of energy storage batteries will be established to determine the planning target for the capacity ratio of the wind-solar storage-transmission hybrid power station construction, as well as determine the space size of the construction site and the construction site. According to the parameter input of the planned capacity, the complementary degree of wind and solar resources, the power output stability of the power station, and the constraint conditions of energy utilization, the optimal capacity ratio of the wind, wind, storage and transmission hybrid power station can be obtained according to the method of the present invention, that is, the wind power generat...

Abstract

The invention discloses a method for planning a station construction capacity ratio of a wind-light storage and transmission mixed power station. In a planning target, energy conservation and emission reduction are quantified on the aspect of earning and fit into the target of planning the station construction capacity ratio of the wind-light storage and transmission mixed power station; meanwhile, on the basis of a station construction site spatial constraint and a station construction planning capacity constraint, constraints of the wind-light resource complementation degree, the power station power output stability and energy utilization degree are introduced so as to finally form a station construction capacity ratio planning model; and the planning model is solved to acquire the station construction capacity ratio of the wind-light storage and transmission mixed power station. By the method, a target function of the planning model and a constraint condition are more in accordancewith an actual situation, so that the acquired station construction capacity ratio is more accurate.

Description

technical field [0001] The invention belongs to the technical field of electric power planning and engineering design, and more specifically, relates to a capacity ratio planning method for building a wind-solar storage-transmission hybrid power station. Background technique [0002] In nature, wind energy and solar energy resources have strong complementarity in time and region. Taking advantage of this complementary feature and introducing energy storage devices at the same time, the wind-solar-storage-transmission hybrid power station can effectively overcome the difference in output power of wind power stations or solar photovoltaic power stations. Stable shortcomings, to ensure the smoothness of the output. [0003] As far as the specific wind-solar-storage-transmission hybrid power station is concerned, how to plan the installed capacity of wind turbines, the installed capacity of photovoltaic modules and the capacity of energy storage devices from a long-term perspect...
