Method for planning regional power grid wind power development

Abstract

The invention provides a method for planning the regional power grid wind power development. The method includes the following steps: building a multi-spatial-temporal scale conventional set output model, building a conventional set output characterization equation, building a wind power set output model, building a production analog computation model based on multi-spatial-temporal scales, and checking the regional power grid stability. By means of the method for planning the regional power grid wind power development, a regional wind power planning model based on electrical power system production simulation is built, and wind power absorptive water balance measurable indicators are built. Operation conditions of links, such as power generating, power transmission and power utilization, of an electrical power system after large-scale wind power integration are analyzed, relevancy of the regional wind power output and loads and the peak load regulation capacity of regional conventional power sources in different seasons are analyzed, conventional power source starting combinations giving considerations to safety limitation are optimized, the electrical power system production simulation study is developed, and wind power quantity absorptive conditions and conventional power source operation conditions are analyzed in the continuous time series.

Description

technical field [0001] The invention belongs to the field of power system planning, and in particular relates to a planning method for wind power development of a regional power grid. Background technique [0002] The Chinese government attaches great importance to the development of wind power, and regards accelerating the development of wind power as a major strategic measure to optimize the energy structure, promote the transformation of energy production methods, and build a safe, stable, economical, and clean modern energy industry system. The Renewable Energy Law formulated a series of supporting policies and supporting measures such as regional electricity prices, cost sharing, and priority grid connection to encourage the development of wind power, which promoted the high-speed, large-scale, and high-level development of wind power in my country and achieved world-renowned achievements. [0003] At the end of 2012, my country's grid-connected wind power reached 60.83 ...

AI Technical Summary

Problems solved by technology

[0005] In view of the relatively concentrated characteristics of wind power development in my country, considering the influence of the inherent characteristics of wind power output such as randomness, intermittency, and uncontrollability, the traditional planning method of analyzing the power balance of sections using typical operation modes cannot effectively reflect the impact of real-time fluctuations in wind power output. Influenced by the system, there is an urgent need to study wind power grid-connected analysis methods to realize the unified and coordinated development of wind power and power grid to provide technical support for wind power and power grid operation and planning
