Intelligent power-limiting power regulating method

Abstract

The invention relates to an intelligent power-limiting power regulating method, and belongs to the technical field of electric power system integrated automation. First corresponding power generation curves are formulated according to everyday power generation situations of an power station and power utilization situations of workdays, weekends and legal holidays and festivals; then dates are divided into workdays, weekends and legal holidays and festivals, so that different dates are associated with the corresponding power generation curves according to the categories that the dates belong to; and finally the photovoltaic power station is controlled to run according to the power generation curve with which a date is associated based on the category to which the date belongs. A user can set different regulation rules as needed, and selects the corresponding power curve to regulate after expected time is reached, and the intelligent power-limiting power regulating method provided by the invention realizes flexible regulation under the power-limiting power generation condition of the photovoltaic power station, and maximally enables the power station to run safely and stably according to the will of the user; and the intelligent power-limiting power regulating method is suitable for both a large-scale photovoltaic power station under dispatching control and a micro distributed power station without dispatching control.

Description

technical field [0001] The invention relates to an intelligent power-limiting power regulation method, which belongs to the technical field of power system comprehensive automation. Background technique [0002] After large-scale photovoltaic power plants and distributed photovoltaic power plants are connected to the grid, the output power needs to be adjusted according to the situation of itself and the power dispatching system, so that the power station can be operated with limited power, which not only ensures the safe and normal operation of the power grid, but also allows the power station to generate as much power as possible. Different time, seasons, and holidays of the power station require different adjustment methods. The adjustment methods are generally divided into weekdays and weekends, the beginning of the month and the end of the month, holidays and non-holidays, etc. It is often necessary to change different operation strategies in different periods to ensure ...

Problems solved by technology

Different time, seasons, and holidays of the power station require different adjustment methods. The adjustment methods are generally divided into weekdays and weekends, the beginning of the month and the end of the month, holidays and non-holidays, etc. It is often necessary to change different operation strategies in different periods to ensure the safety and stability of the power grid. run, and allow the power station to generate electricity with high load; currently the power regulation system can only run according to the dispatching instructions, or run by the user; after the dispatching system is overhauled, or the user sets it for a period of time, the user needs to reset it according to the requirements, regular Work seriously reduces work efficiency
