Abstract

The invention discloses an alliance market quotation strategy determination method for a wind power and heat and power cogeneration unit. The method comprises the following steps: building a day-aheadrandom optimization model and a real-time random optimization model according to the double coupling relation between the day-ahead operation and real-time operation of the wind power and heat and power cogeneration unit; according to the two-stage random optimization model, determining the maximum expected income of the alliance of the wind power and heat and power cogeneration unit; and determining the alliance market quotation strategy according to the maximum expected income. According to the alliance market quotation strategy determination method of the wind power and heat and power cogeneration unit, the two-stage random optimization model is constructed, the day-ahead operation stage and the real-time operation stage are optimized, the uncertainty factors of wind power output are fused, and by using the model, the maximum expected income of the alliance of the wind power and heat and power cogeneration unit can be quickly and effectively determined, and a basis is provided forthe market quotation strategy of the alliance of the wind power and heat and power cogeneration unit.

Description

technical field [0001] The invention relates to the field of optimal dispatching of power systems, in particular to a market quotation strategy and income distribution method for joint participation of wind power, heat and power cogeneration units. Background technique [0002] In recent years, under the encouragement of relevant national policies, my country's wind power has developed rapidly. Due to the uncertainty and weak regulation ability of this kind of fluctuating power supply output, the high proportion of access requires the power system to provide more flexible regulation services. At present, the active adjustment ability of renewable energy represented by wind power on the "source side" of the energy grid is deteriorating day by day, leading to many difficulties in the grid economy and resulting in large-scale curtailment of wind. [0003] In this environment, it will become a trend for wind power operation to switch from a protective full grid connection to pa...
