Day-ahead power generation plan optimization method and system thermal power fusion and electric energy storage combined peak shaving

Abstract

The invention discloses a day-ahead power generation plan optimization method based on thermal power fusion and electric energy storage combined peak shaving. The day-ahead power generation plan optimization method comprises the following steps: S1, acquiring relevant parameter information of deep peak regulation and electric energy storage bidirectional peak regulation of a thermal power generating unit, and generating a day-ahead power generation plan calculation scene of thermal power fusion and electric energy storage combined peak regulation in combination with various parameter information required by a day-ahead power generation plan; S2, generating a day-ahead power generation plan optimization model of thermal power fusion electric energy storage combined peak regulation accordingto the parameter information in S1; and S3, carrying out optimization calculation and safety check on the day-ahead power generation plan optimization model of thermal power fusion electric energy storage combined peak regulation generated in the S2 to obtain a day-ahead power generation plan, and clearing the price of a peak regulation auxiliary service market. The day-ahead power generation plan optimization method can improve the day-ahead plan execution rate, promote the new energy consumption and meet the increasingly lean large power grid safety operation demands under the condition offully evaluating the next-day new energy consumption capability and the system load peak regulation demands in combination with the next-day power grid operation mode.

Description

technical field [0001] The invention belongs to the technical field of electric power system scheduling automation, and in particular relates to a method and system for optimizing a day-ahead power generation plan of thermal power fusion, electric energy storage, and peak regulation. Background technique [0002] At present, the main reasons for the increasing pressure on domestic power grid peak regulation include the high proportion of thermal power installed capacity, shortage of peak regulation resources, large-scale grid connection of new energy sources, and gradually increasing load peak-valley difference. The inability to meet the safe operation requirements of large-scale new energy grid connection has led to the abandonment of wind and light, and the problem of wind and light abandonment is particularly prominent during the winter heating period in the "Three North Regions". [0003] In order to alleviate the urgent pressure of domestic power grid peak regulation an...

Problems solved by technology

The peak shaving auxiliary service market is cleared based on unit peak shaving quotations and system peak shaving demand. The size of peak shaving demand is adjusted in real time according to changes in network topology, load forecasting, and new energy forecasting. It cannot be accurately estimated in advance. In addition, the peak shaving market Clearing needs to take into account its impact on the safety of the power grid. Therefore, the joint peak shaving and clearing of the planning and peak shaving auxiliary service market is the best model to adapt to the domestic three-public dispatching operation. The matching thermal power fusion power storage joint peak shaving The day-ahead power generation plan optimization method is the core content of the present invention
