Method for jointly scheduling power generation load by using wind power generation unit and thermal power generation unit

Abstract

The invention discloses a method for jointly scheduling power generation load by using a wind power generation unit and a thermal power generation unit. A wind power plant, a circulating fluidized bed unit, a heating unit and the like which are within a same area or belong to a same power generation group are equivalent to a virtual unit, unified load instructions are issued from a power grid side, and the load instructions are decomposed on a unit side according to characteristics of various units to realize operation of the wind power plant at the maximum power generation power, wide-range variable load operation of the circulating fluidized bed unit and high-rate variable load operation of the heating unit. Mutual coordination of the wind power plant, the circulating fluidized bed unit and the heating unit is realized under the joint scheduling of a power grid, advantages of each unit are fully utilized, capacity of the power grid to receive wind power generation load is greatly improved, and the maximum-power operation of the wind power plant is realized while safety in operation of the power grid is guaranteed, so that waste of wind energy is reduced and power generation cost and environmental pollution are reduced.

Description

technical field [0001] The invention relates to a method for jointly scheduling power generation loads of a wind turbine unit, a circulating fluidized bed unit and a heating unit, and belongs to the technical field of power generation. Background technique [0002] Wind power is a clean and renewable energy generation method that has developed rapidly in the past decade. Taking China as an example, a large number of wind power plants are connected to the grid to generate electricity in the northwest, north, northeast and southeast coastal areas. With the increase of wind turbine unit capacity and the large-scale development of the wind power industry, the construction and operation costs of wind turbines have been continuously reduced, the economic advantages of wind power have gradually emerged, and the profitability of wind power enterprises has increased significantly. [0003] It is difficult to store electric energy on a large scale. The grid side needs to dispatch the...

AI Technical Summary

Problems solved by technology

The load adjustment range of a typical thermal power unit is 50% to 100% of the rated load, and the adjustment rate is 1.5% of the rated load per minute, which cannot fully meet the requirements of compensating the wind power load.
