A Coordinated Scheduling Method for Combined Heat and Power Generation and Wind Power with Heat Storage

Abstract

The invention provides a thermal-storage cogeneration and wind power coordinated scheduling method. The method includes of: obtaining the initial day-ahead plan data of a system and the thermal storage parameter of a thermal storage device; establishing, according to the initial day-ahead plan data of the system and the thermal storage parameter of the thermal storage device, the day-ahead plan model of a thermal-storage cogeneration and wind power coordinated scheduling system and establishing the day-ahead scheduling plan of the thermal storage device; acquiring intraday rolling forecasting data; based on the day-ahead plan data and the intraday rolling forecasting data, establishing an thermal-storage cogeneration and wind power coordinated operation intraday rolling plan model and an intraday rolling scheduling plan. In order to cope with the uncertainty of wind power forecasting, the thermal-storage cogeneration and wind power coordinated scheduling method takes account of a promotion effect of thermal storage on wind power consumption from two aspects of day-ahead rolling and intraday rolling, and establishes a corresponding thermal-storage cogeneration and wind farm scheduling plan so as to achieve reasonable output of each unit.

Description

technical field [0001] The invention relates to the technical field of new energy and high-efficiency energy-saving, in particular to a method for coordinating cogeneration of heat and power with heat storage and wind power. Background technique [0002] The northern region of my country is rich in wind resources, and the installed capacity of wind power is expanding year by year. However, the severe wind curtailment in this region during the heating period in winter has become the primary bottleneck restricting the development of wind power. Wind power output is volatile and uncertain, and there is a mismatch between it and the power load demand. [0003] Wind curtailment refers to the suspension of wind turbines in some wind farms due to their own characteristics such as insufficient capacity of the local power grid, mismatched construction period of wind farms, and unstable wind power in the early stage of wind power development when the wind turbines are under normal con...

Problems solved by technology

However, the existing dispatching system does not have the ability to dispatch heat storage devices, and it is difficult to give full play to the regulating role of heat storage devices in the coordination and dispatching of wind power consumption.
