Embodiment Construction

[0074] The technical scheme of the present invention will be further described below in conjunction with the accompanying drawings.

[0075] as attached figure 1 As shown, the present invention provides a bidding method for a new-storage station to participate in the electric energy-frequency modulation auxiliary service market, wherein the new-storage station is suitable for new energy stations such as wind power and photovoltaics. The steps are:

[0076] Step 1: Use the Monte Carlo sampling method to construct a probabilistic scene set, and complete the scene reduction through the clustering method; the specific implementation process is: use the scene analysis method to construct an uncertain set of new energy output, load curve, and market electricity price, and use Monte Carlo The Carlo sampling method constructs various scene sets, and then selects an appropriate clustering method to complete scene reduction, thereby obtaining typical scenes of new energy power plants. ...

Abstract

The invention discloses a bidding method for a new-storage power station to participate in an electric energy-frequency modulation auxiliary service market. According to the technical scheme, the method comprises the steps of: constructing a probabilistic scene set through a Monte Carlo sampling method, and performing scene reduction through a clustering method; establishing an operation model of a new-storage power station; processing risks caused by uncertainty by adopting a conditional value-at-risk theory, and establishing a new-storage power station benefit evaluation model; and according to the obtained probabilistic scene set, establishing a bidding model for the new-storage power station to collaboratively participate in the electric energy-frequency modulation auxiliary service market by taking benefit maximization as a target. According to the method, the new energy output fluctuation error is reduced, the tracking day-ahead scheduling plan of the new-storage power station is improved, and the income level of the new-storage power station participating in the power market is effectively improved.

Description

technical field [0001] The invention relates to the field of electric power market bidding, in particular to a bidding method for new-storage power stations participating in the electric energy-frequency modulation auxiliary service market. Background technique [0002] In recent years, the trend of global warming has continued to intensify, extreme weather and climate events have occurred frequently, and the negative impact of climate change on the human living environment and social development has become more and more obvious. It has gradually become the consensus of the international community to accelerate the transformation and upgrading of the power supply structure and realize the sustainable development of energy. Countries continue to promote renewable energy grid-connected programs to cope with climate change. In this context, a high-proportion renewable energy grid-connected system based on wind power and photovoltaics will become an inevitable trend in the devel...
