Abstract

The invention discloses a wind-power-absorption-oriented electric power system peak load regulation means economic assessment method and system. The wind-power-absorption-oriented electric power system peak load regulation means economic assessment method includes the following steps: acquiring the sequential theory output of a wind turbine generation set in a specific time at a specific area, and the operating characteristic and the sequential load demand of a conventional power supply generation set; respectively acquiring the abandoned wind quantity of a wind power plant in a current electric power system and the abandoned wind quantity of a wind power plant in a scene employing the corresponding peak load regulation means; determining the corresponding decrement of abandoned wind and constructing a corresponding cost model and the unit peak load regulation cost; and determining the optimum peak load regulation scheme. The wind-power-absorption-oriented electric power system peak load regulation means economic assessment method can realize acquisition of the abandoned wind electric quantity of the wind power plant under each peak load regulation means on the basis of sequential production simulation and establish each peak load regulation means cost model so as to construct an economic assessment index and perform quantitative assessment on the effect of improving wind-power-absorption of the system by means of different peak load regulation means to obtain the peak load regulation means with the optimum cost effectiveness, and has better practical guidance meaning and application value for the electric power system to adapt to new energy efficient absorption and for improvement of the peak load regulation capability of a power grid.

Description

technical field [0001] The invention relates to the technical field of electric power simulation analysis, in particular to a method and system for evaluating the economics of a peak-shaving means of a power system for wind power consumption. Background technique [0002] At present, wind power generation is one of the power generation methods with the most mature technology, the most large-scale development conditions and the most commercial development prospects in energy power generation. With the increasing proportion of wind power in the power structure, its impact on the safe and stable operation of the power system is becoming more and more significant. The contradiction between the development of wind power and the safe operation of the system in some areas is becoming more and more obvious, and the phenomenon of wind curtailment continues to appear. Wind power consumption has become a key issue affecting the healthy development of wind power in China. [0003] Due ...
