Abstract

The invention discloses an analysis method of renewable energy grid-connected power generation. The analysis method comprises the steps of direct economic benefit analysis, auxiliary service cost analysis and environmental benefit analysis, wherein the direct economic benefit analysis comprises the step that a system dynamics model of the direct economic benefit analysis of the renewable energy grid-connected power generation is established, and the model includes renewable energy generating capacity, renewable energy grid-connected power generation incomes and renewable energy grid-connected power generation costs; for the auxiliary service cost analysis, the auxiliary service refers to a necessary service for maintaining the safe and stable operation of electric system and ensuring power quality, a system dynamics model of the auxiliary service cost analysis is established, and the model includes peak regulation costs, frequency modulation costs and spinning reserve costs; and the environmental benefit analysis comprises the step that a system dynamics model of the environmental benefit analysis of the renewable energy grid-connected power generation is established, the model adopts the system dynamics principle, analyzes the relations of elements of the environmental benefit of the renewable energy power generation, and mainly includes renewable energy generating capacity and emission reduction benefits under the support of correlation techniques and policies.

Description

technical field [0001] The invention relates to an analysis method, in particular to an analysis method for renewable energy grid-connected power generation. Background technique [0002] At present, in recent years, more and more renewable energy sources have been applied to the existing power grid. However, since renewable power sources are often scattered, many of them are far away from the load center. To transmit power, it needs to be connected to the end of the grid for remote distance delivery. However, the terminal structure of the power grid is weak and difficult to access, and it may be difficult to withstand the fluctuations caused by the instability and randomness of some renewable energy sources; on the other hand, after renewable energy is connected to the grid, the power supply and operation of the grid It will also have an impact, which will affect the economic benefits of grid enterprise operations. The large-scale development of renewable energy power gen...
