Combined heat and power scheduling method for improving secondary absorption capacity of wind power

Abstract

The invention discloses a combined heat and power scheduling method for improving the secondary consumption capacity of wind power, which comprises the following steps of: 1, determining a secondary wind power consumption mode, and defining a start-stop control strategy of a heat accumulating type electric boiler; 2, according to inequality constraints which should be met in the peak shaving participation process of the wind turbine generator and the thermoelectric unit, defining a feasibility coefficient to determine a unit power generation right price; 3, determining an objective function and constraint conditions in the combined heat and power dispatching model under peak load regulation right transfer; and 4, carrying out optimization solution on the combined heat and power dispatchingmodel by adopting a dynamic inertia weight and a particle swarm algorithm to achieve combined heat and power dispatching. The scheduling strategy provided by the invention can effectively reduce theintermittency and fluctuation of wind power, improve the wind power consumption and increase the benefit of an electrical comprehensive energy system.

Description

technical field [0001] The invention relates to the field of energy, in particular to a combined heat and power scheduling method for improving the secondary absorption capacity of wind power. Background technique [0002] In recent years, wind power has become the fastest growing and most widely used clean energy by virtue of its advantages of wide distribution, no pollution, and renewable. However, in my country's "Three Norths" region during the winter heating period, thermal power units are usually dispatched in accordance with the "heat-based power" model because they undertake the heating task in the region. The high proportion of large thermal power units limits the peak-shaving capacity of the power system. As a result, the ability of the grid to accept wind power has declined sharply. The traditional scheduling method is to make the system maintain the balance between power supply and demand by means of abandoning wind; thus causing energy waste. However, with the d...
