Embodiment Construction

[0056] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0057] Such as figure 1 As shown, the present invention provides a constrained multi-objective optimization wind farm power control method. According to the power demand issued by dispatch and the optimization target of the wind farm, a multi-objective optimization function is established and the function is solved by a swarm intelligence algorithm to obtain the power output of the wind turbine. command, so that the total output of the wind farm power meets the requirements of the dispatch command, which specifically includes the following steps:

[0058] Step 1: Measure and obtain the current output power P of the wind farm real , the dispatching power target value P target , the target value...

Abstract

The invention discloses a constrained multi-objective optimization wind power plant power control method. The method comprises the following steps: a, acquiring the actual output power Preal of a windpower plant at the current moment; b, generating a multi-objective optimization control instruction v; c, determining an adjustable power constraint range of each fan; d, setting a fan control efficiency matrix B; e, judging whether the dispatched and issued power output instruction is executable or not, if yes, executing the step f, and otherwise, returning to the step a; f, establishing an objective function J which contains constraint conditions and can optimize a plurality of objectives at the same time; g, solving the target function J by using a swarm intelligence algorithm to obtain anoptimal solution u which meets constraint conditions and an optimization target at the same time to serve as a power output instruction of each fan; and h, after the wind turbine generator executes the instruction action, returning to the step a. According to the constrained multi-objective optimization wind power plant power control method provided by the invention, a plurality of optimization objectives can be set at the same time, and an optimal power control scheme is obtained, so that the income obtained by the wind power plant is optimized.

Description

technical field [0001] The invention relates to a method for controlling power of a constrained multi-objective optimized wind farm, which belongs to the technical field of wind power generation. Background technique [0002] In recent years, wind power has been vigorously developed as a renewable clean energy power generation. Wind power generation is random, intermittent and uncontrollable. The large-scale connection of wind power generation has a great impact on the safe operation of the power system. Among them, the power control problem has received a lot of attention, and it is also the most common problem in actual operation. one. [0003] According to the requirements of the "Technical Regulations for Connecting Wind Farms to Power Systems" issued by the State Grid Corporation of China, wind farms need to be able to control power output according to the instructions of the grid dispatching department. Therefore, how to effectively convert the dispatching instructio...
