Embodiment 1

[0093] Taking the IEEE 30-node system as an example, the life of the wind turbine is 20 years; the operating parameters of the dispatchable conventional generating set in the system are shown in Table 1; 0.5￥ / (kW·h), the environmental benefit is equivalent to 0.0926￥ / (kW·h), all confidence levels are taken as 0.9, and the optimization results are shown in Table 2. For the installed capacity intervals of wind farms [99,154]]MW (interval 1) and [85,99]MW (interval 2).

Abstract

The invention relates to a decision-making method for a wind farm installed capacity interval based on D-U space hybrid multi-attribute, which uses the social benefit of wind farm power generation, wind abandonment rate, power grid line transmission safety margin and power shortage risk as attribute indicators to establish a wind farm. For the attribute matrix of the interval to be decided, a hybrid multi-attribute evaluation based on the set pair analysis D-U space is introduced to determine the optimal installed capacity interval of the wind farm.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a decision-making method for the installed capacity interval of a wind farm based on D-U space mixed multi-attribute. Background technique [0002] As countries around the world attach importance to environmental protection and demand for sustainable energy development, the focus of energy development has shifted to renewable energy. As the main utilization method of renewable energy, wind power has an unstoppable rapid and large-scale development. It is accompanied by the frequent occurrence of wind curtailment, the uncertainty of power grid operation and the decline of power quality. Therefore, a large number of studies have been conducted to evaluate the ability of the grid to accept wind power from the perspective of security, economy and resource utilization. Due to the changes in the operation mode of the power grid, the expansion of the grid planning and th...
