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.
