The embodiments of the invention provide an active power and reactive voltage control method and device of a wind-storage combined power generation system, wherein the method comprises the steps of: obtaining the active power and reactive voltage of an energy storage power station in real time; according to the deviation of the active power and the deviation of the reactive voltage, determining the priority of adjustment carried out on an active power instruction and a reactive voltage instruction; and according to the determined priority, adjusting the active power instruction and the reactive voltage instruction. According to the scheme, the active power and the reactive voltage of the energy storage power station are coordinated and corrected according to the priority.
Description
technical field [0001] The invention relates to the field of new energy technologies, in particular to a method and device for controlling active power and reactive voltage of a wind-storage combined power generation system. Background technique [0002] New energy represented by wind power has developed by leaps and bounds in the past 10 years. As of June 2015, the cumulative grid-connected capacity of wind power in my country was 105.53 million kilowatts, and the cumulative installed capacity and newly installed capacity of wind power ranked first in the world. The rapid development of new energy provides a broad application space for large-scale energy storage. The use of energy storage devices to redistribute intermittent energy such as wind power in time can play a role in gathering and abandoning wind, cutting peaks and filling valleys, and smoothing fluctuations, thereby improving the continuity and stability of new energy power generation and improving grid consumpti...
