Large-scale grid-connected wind power consumption method based on demander response

Abstract

The invention relates to the research field that a demander response participates in large-scale grid-connected wind power consumption, in particular to a large-scale grid-connected wind power consumption based on the demander response. The method comprises the steps of establishing high-energy-consumption enterprises of mining, metal smelting, petroleum processing, heating and the like nearby areas with rich wind power, utilizing adjustable and interruptible high-energy-consumption loads for participating in wind power pitch peaks, locally absorbing wind power resources, and avoiding large-scale and remote wind power transmission. Therefore, power grid losses are reduced, the power utilization cost of high-energy-consumption users is saved, output consumption of a wind power plant is increased, and occurrences of the wind abandoning phenomenon are reduced. The method can objectively and comprehensively reflect the output characteristics of large-scale power wind and the user power utilization load characteristics, the sizes of the adjustable and interruptible high-energy-consumption loads are accurately calculated, then the capacity of the newly-increased wind power consumption scale is determined, and the current large-scale wind power grid-connected consumption problem and the wind abandoning problem are solved.

Description

technical field [0001] The invention relates to the research field of demand-side response participation in large-scale grid-connected wind power consumption, and in particular to a method for large-scale grid-connected wind power consumption based on demand-side response. Background technique [0002] As a new energy power generation technology with relatively mature technology, low cost and large-scale development, wind power will play an irreplaceable role in adjusting energy structure, coping with climate change, and mitigating environmental pollution. my country's wind energy resources are abundant and concentrated. According to the overall idea of ​​"building large bases and integrating into large power grids", my country plans to build seven 10 million-kilowatt wind power bases in the "Three Norths" and the eastern coastal areas such as Jiuquan and Hami. In the future, my country's wind power will develop rapidly on a large scale. A correct understanding of the charac...

Problems solved by technology

The incentives for power companies to implement demand-side management issues are mainly to ensure that they can safely pass through the peak load period, which is regarded as a political task; economically, there is no incentive, or even a negative incentive: From the perspective of power companies, the implementation of peak and valley, peak and low electricity prices , is to use a certain range of profit to guide users who implement peak and low electricity prices to avoid peaks. The weighted average electricity price of these users must be lower than the catalog electricity price before its implementation, so there is a loss in electricity price, while the implementation of load control has power consumption. loss

At the same time, there is no economic compensation for users participating in load control. It is basically an administrative means. The traditional method of power cuts is still widely used when supply and demand are tight, but it has been increasingly questioned and criticized by users for its legitimacy. Economic claim requirements

The implementation and advancement of the demand side management topic is faced with the embarrassment of the lack of implementation subjects and the serious lack of incentives and motivation
