A capacity ratio planning method for wind-solar-storage-transmission hybrid power station construction

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...
