A wind power cooperative game climbing control method and device

Abstract

The embodiment of the invention provides a wind power cooperative game climbing control method and device, and the method comprises the steps: providing a field group complementarity evaluation indexaccording to the active power deviation of a wind power field group; By utilizing complementary characteristics among the wind power plants and combining a field group control mode, providing field group climbing control based on complementarity; Constructing a payment function according to deviations between the wind power plant output and the output adjustment amount and between the actual windpower plant output and the planned value; Selecting different game strategies for the wind power plant, and providing a calculation method of the wind power plant adjustment amount in a climbing event; And according to the field group complementarity evaluation index and the payment function, based on a cooperative game mode, establishing a cooperative game mechanism to guide the wind power plantto participate in field group climbing control. The completion degree of the wind power plan of the field group can be improved when the climbing event occurs, the paid compensation cost of each windpower plant is reduced, and the wind power plant income is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wind power grid connection, and more specifically, to a wind power cooperative game climbing control method and device. Background technique [0002] In recent years, new energy power generation technologies dominated by wind power and photovoltaics have developed rapidly. In 2017, the cumulative installed capacity of wind power in my country reached 164GW, with an annual growth rate of 28%. With the increase of wind power penetration, the possibility of ramp events in the system increases due to the influence of long-term extreme weather. The wind power ramp event is a one-way large-scale change event of wind power in a short time scale, which can easily cause a large short-term power shortage in the system, affect peak regulation and frequency regulation, and seriously threaten the safe, stable and economic operation of the power grid. [0003] The domestic and foreign resear...

Problems solved by technology

With the expansion of wind power grid-connected scale, in order to reduce the cost of wind power regulation and operation, countries have formulated corresponding error penalty measures for the deviation between wind power generation plan value and actual operation situation, so as to encourage joint cooperation of different wind farms and reduce their overall active power deviation; However, the existing competitive game climbing control method fails to fully consider the ancillary service compensation fees due to the difference between the planned value and the actual value when wind power is connected to the grid, which is likely to damage the economic benefits of the wind farm.
