Method of intertidal zone wind power for accessing power grid

Abstract

The invention discloses a method of intertidal zone wind power for accessing a power grid. The method comprises the following steps: step 1, determining an influence factor set; step 2, evaluating the power grid state; step 3, dividing the planning area into supply districts which are of different layers, connected but independent; step 4, carrying out load prediction, and performing load characteristic analysis and prediction with some emphasis; step 5, formulating a transformer substation layout and a wire frame scheme; step 6, analyzing wind power consumption capacity in the planning area and each supply district; step 7, determining wind power integration mode of the intertidal zone wind power access applicable for each power supply district; step 8, carrying out scheme optimization; step 9, providing the final suggestion. By virtue of the method, in the power grid planning phase, the wind power resource characteristics and the power grid operation requirements can be both considered about to realize that the total investment cost for power grid construction is optimized.

Description

technical field [0001] The invention relates to a grid component method, in particular to a method for intertidal zone wind power connected to the grid. Background technique [0002] Wind power is a renewable energy with great resource potential and basically mature technology. Under the new situation of reducing greenhouse gas emissions and coping with climate change, it has attracted more and more attention from all countries in the world, and has been developed and utilized on a large scale around the world. During the "Eleventh Five-Year Plan" period, my country's wind power has developed rapidly. The installed capacity of wind power has doubled continuously, and the equipment manufacturing capacity has increased rapidly. A relatively complete industrial system has been formed, laying a good foundation for the development of wind power on a larger scale. With the advancement of wind power technology and the continuous decline in costs, my country also places high hopes o...

Problems solved by technology

The current power grid planning is mostly based on power supply construction planning and load demand forecasting. Several empirical schemes are proposed, and deterministic fault verification is performed on each scheme. On the basis of ensuring the safety of power grid operation, the investment and adaptability of each scheme are compared. To make decisions, this approach cannot meet the operational requirements of reliability, flexibility and economy, and does not plan according to the principle of optimal development cost, and cannot adapt to the requirements of large-scale development of wind power under the new situation
