Photovoltaic power station active power change rate control method and system, and storage medium

Abstract

The invention discloses a photovoltaic power station active power change rate control method. For the photovoltaic power plant active power change rate control, a method of combination of periodic adjustment and real-time sudden drop detection is adopted to effectively solve the photovoltaic power station active power change rate out-of-limit problem in the various weather work condition. The maximum limit remaining amount of the 10-minute active power change rate is calculated in real time, a 1-minute active power change rate limit value is corrected in a rolling mode to meet the requirementsof the 1-minute active power change rate and the 10-minute active power change rate at the same time and maximize the photovoltaic generating capacity of the photovoltaic power station.

Description

technical field

[0001] The invention belongs to the technical field of power system control, and in particular relates to a method, system and storage medium for controlling the rate of change of active power of a photovoltaic power station. Background technique:

[0002] In recent years, photovoltaic power generation has been vigorously developed as a renewable clean energy power generation. Due to the randomness and volatility of photovoltaic power generation, the grid connection of large-scale photovoltaic power plants will affect the safe and stable operation of the power grid, especially the short-term and large fluctuations of photovoltaic power will bring a huge impact to the power grid. "Q / GDW 617-2011 Technical Regulations for Connecting Photovoltaic Power Stations to the Grid" puts forward specific requirements for the 1-minute active power change and 10-minute active power change limits of photovoltaic power stations under normal operation conditions, so it is nec...
