Abstract

The invention discloses a new energy field station power limiting time period active distribution method. The method comprises the steps of obtaining a new energy power limiting total demand in an area; Analyzing a plurality of indexes of each new energy field station to form a calculation method of each index; Carrying out comprehensive evaluation on the plurality of indexes, and calculating a comprehensive evaluation index of each new energy field station; And calculating the limited electric quantity of each new energy field station according to the comprehensive evaluation index of each new energy field station. The invention provides a new energy field station power limiting time period active distribution method. the distribution strategy is dynamically optimized by comprehensively considering the actual operation condition of each new energy field station; According to the historical operation trend, the electric quantity transaction completion condition and the system stable operation support condition of the new energy field station, the electric quantity sharing coefficient of each new energy field station in the electricity limiting time period is established, so that the new energy field station with excellent operation condition and low transaction electric quantity completion condition can carry out more active power output in the electricity limiting time period,and fair scheduling is ensured.

Description

technical field [0001] The present application relates to the technical field of new energy stations, and in particular to a method for allocating active power of new energy stations during power-limiting periods. Background technique [0002] New energy is a kind of fluctuating and intermittent power supply, which increases the uncertainty of the power flow. The grid-connected operation of new energy will have many impacts on the operation of the main grid. In principle, new energy plants and stations adopt the mode of full consumption. In the case of small installed capacity of new energy power plants, new energy has little impact on the stability of the system. [0003] As the proportion of new energy increases year by year, in areas with a high proportion of new energy access, new energy stations often choose stations with good adjustment capabilities and fast response speeds for correction and adjustment when the cross-section channels are limited. As a result, there a...
