Problems solved by technology
[0003] However, the current policy does not take into account the structural problems of large-scale wind power and conventional units in my country: intermittent wind power generation requires flexible conventional units for fluctuation balance
Under the current mechanism, the interests and risks faced by the grid operator cannot form an intersection, and even the two are increasingly divergent. With the large-scale grid connection of wind power, the power grid will lack the power to absorb wind power

Embodiment Construction
[0036] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0037] The invention provides a method for analyzing the cost of unit spinning standby in a power system containing wind power. The method takes the lowest system standby cost as the goal, establishes a standby optimization model, and obtains the total standby cost of the system through optimization calculation; The list of spinning standby units that undertake intermittent fluctuations in wind power; analyze the time-based spinning reserve costs for each conventional unit that undertakes intermittent fluctuations in wind power according to the ratio of spare space.
[0038] Such as figure 1 as shown, figure 1 for figure 1 It is a flow chart of the cost analysis method for unit spinning reserve in the power system including wind power based on the coordinated optimization of multiple power sources in this embodiment.

The invention provides a method for analyzing a machine set spinning reserve cost in a wind power system. The method comprises the following steps: I, determining a total reserve cost of the wind power system; II, determining a machine set bearing wind power intermittent fluctuation reserve in a conventional machine set; and III, determining the machine set spinning reserve cost of the wind power system according to a spare space proportion sharing method. The invention provides a wind power reserve cost sharing method, and provides the wind power intermittent fluctuation reserve cost of each machine seat at each time period, the method is simple in principle, and the provided cost value can lay a foundation for the research on the transaction mechanism of the conventional machine set and the wind power machine set.
Description
technical field [0001] The invention relates to a method in the field of electric power automation, in particular to a method for analyzing the spinning reserve cost of a unit in a power system including wind power. Background technique [0002] According to the distribution characteristics of wind power in my country, "building large bases and integrating into large power grids" has become the main mode of wind power development in my country, and related economic policies for wind power generation have been introduced in conjunction with it. Development Fund Subsidy. This policy effectively promoted the development of wind power, and greatly promoted the investment and construction of wind power in the early stage of wind power development. [0003] However, the current policy does not take into account the structural problems of large-scale wind power and conventional units in my country: intermittent wind power generation requires flexible conventional units for fluctuat...
