Problems solved by technology

Therefore, improving the penetration power of wind power should not only be considered from the power generation side and the transmission side, but should also be considered through the demand side to suppress wind power fluctuations and anti-peaking characteristics, thereby increasing the limit of wind power penetration power

Embodiment Construction

[0088] A calculation method of wind power breakthrough power limit considering demand side response, comprising the following steps:

[0089] Step 1: Establishment of wind power active output model:

[0090] The general wind speed distribution can be described by the Weibull distribution curve, and its probability density function can be expressed as:

[0091] p ( x ) = k c ( x c ) k - 1 exp [ - ( x c ) k ] - - - ( 1 )

[0092] In the formula: k is a parameter that determines the shape...

Abstract

The invention belongs to the field of dispatch of a power grid with wind power, and particularly relates to a wind power penetration limit calculation method in consideration of demand side response. The ability of absorbing the wind power by the power grid is enhanced through simultaneous control on source and load sides. The method mainly comprises steps: an active power output model for the wind power is built; a demand side response model is built; ideas of the economics and a node admittance matrix are used for building an electricity price sensitivity concept; a wind power generation limit penetration power expression is determined; and necessary constraints in an event are added in the case of calculation for simulation calculation. The result shows that by adopting the method of the invention, the wind power integration rate can be improved, and a greater wind power capacity can be integrated.

Description

technical field [0001] The invention relates to a calculation method of wind power breakthrough power limit considering demand side response, which belongs to the field of power grid dispatching including wind power. Background technique [0002] As a renewable energy with relatively mature technology, wind energy has extremely broad development prospects. In the future, my country's wind power will gradually rise from the current supplementary energy to an alternative energy or even a dominant energy. However, the output of wind power is uncontrollable, and has the characteristics of randomness, volatility, and anti-peak regulation. Its large-scale access to the power system will have a significant negative impact on the peak regulation balance of the system, and this effect will in turn become Bottleneck 1 restricting the development of wind power. Therefore, it is of great theoretical and practical significance to study the solution of the penetration power limit of wind ...
