Problems solved by technology

Due to the randomness and uncertainty factors of load power and wind power output, the spinning reserve benefit of the wind power power system becomes an uncertain factor, which is difficult to estimate accurately, so it is necessary to evaluate the risk of spinning reserve benefit

Embodiment Construction

[0061] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0062] like figure 1 As shown, this embodiment provides a method for assessing the benefits and risks of spinning reserve power systems containing wind power, which specifically includes the following steps:

[0063] Step S1: Extract the capacity price, energy price, unit lost load price, and wind curtailment price of the system spinning reserve;

[0064] Step S2: Establish the maximum system spinning reserve benefit expectation model; due to the forecast deviation of load power and wind power output, the spinning reserve benefit is not a definite value, so the expected spinning reserve benefit is used as the estimated value of the spinning reserve benefit. Define the model: the difference between the expected value of reducing the loss due to the purchase of spinning reserve and the expected value of the cost of spinning reserve within 24 hours of the...

Abstract

The invention relates to a method for estimating spinning reserve benefit and risk of a wind power system. The method comprises the following steps: after extracting a capacity price, an energy price, a unit load price and an abandoned wind price of system spinning reserve, establishing a maximum system spinning reserve benefit expected value module and a minimum system spinning reserve benefit risk model; and finally solving an expected spinning reserve benefit value and an expected spinning reserve benefit value. According to the method for estimating the spinning reserve benefit and risk of the wind power system, the relationship between the spinning reserve benefit and risk is described more intuitively, and reference is provided for the spinning reserve deciders to draw up spinning reserve plans and estimate the expected spinning reserve benefit and risk.

Description

technical field [0001] The invention relates to the field of power market analysis, in particular to a method for evaluating the benefit and risk of a spinning reserve power system including wind power. Background technique [0002] Large-scale wind power grid connection has a significant impact on the reliability and economy of the power system; due to the randomness of load power and wind power output, it is extremely difficult to formulate a spinning reserve plan for the system, so related literature has also been carried out A lot of research has achieved a lot of research results. However, there are few studies on the evaluation of the benefits and risks of large-scale wind power grid-connected spinning reserve. The system purchases the spinning reserve to ensure the reliability of the system, but also strives to generate the maximum benefit of the spinning reserve and reduce the risk of the system at the same time. Therefore, how to balance the benefits and risks of ...
