Abstract

The invention discloses a comprehensive evaluation method for a power grid planning scheme under a wind power grid connection condition, and belongs to the field of power system planning scheme evaluation. The method comprises the following steps of firstly, establishing a to-be-evaluated power grid planning scheme set, then constructing a power grid planning scheme comprehensive evaluation indexsystem comprising five evaluation dimensions and three evaluation levels, and setting the weight of each evaluation index; calculating a score value of a technical layer evaluation index for each to-be-evaluated power grid planning scheme, further obtaining a comprehensive evaluation value of each to-be-evaluated power grid planning scheme, and obtaining a power grid planning scheme with optimal comprehensive evaluation. According to the method, the influence of large-scale wind power grid connection on power grid planning can be considered, and the most reasonable power grid planning scheme is obtained, so that the wind power consumption level is improved, and the operation safety and efficiency of a power system are improved.

Description

technical field [0001] The invention belongs to the field of power system planning and evaluation, and in particular relates to a method for comprehensive evaluation of power grid planning schemes under the condition of wind power grid-connected. Background technique [0002] In recent years, wind power has developed rapidly in my country, and the installed capacity and power generation have continued to increase. In 2017, the accumulative grid-connected installed capacity of wind power across the country reached 164 million kilowatts, accounting for 9.2% of the total installed capacity of power generation, and the wind power generation was 305.7 billion kWh, accounting for 4.8% of the total power generation. Wind power technology is relatively mature, and its cost keeps falling. In the future, it will still be an important means for my country to further promote the energy production and consumption revolution and promote the prevention and control of air pollution. It is e...
