Problems solved by technology

The document "Atsushi Yona, Hideomi Sekine, Chul-Hwan Kim, Output power control for large wind power penetration in small power system, Renewable Energy, 2009" aimed at the single-domain wind-diesel hybrid power system, through the fuzzy control method to realize the wind power output power frequency adjustment, but this must reduce the penetration rate of wind power. Although the method is feasible, it does not make full use of new energy

Abstract

The invention relates to a load frequency coordination control method of a fan-participated frequency modulation wind-diesel hybrid power system. The wind-diesel hybrid power system comprises a wind power generation sub-system and a diesel engine sub-system. The load frequency coordination control method comprises the following steps of (1) using a power output of the wind power generation sub-system as a control input of the diesel engine sub-system, establishing a system state equation and using a sliding-mode controller to calculate the control input u (t) of the diesel engine sub-system in the hybrid power system; (2) using the u (t) obtained in the step (1) through calculation as a control instruction of the wind power generation sub-system, adopting a PID variable pitch control method to control the output power of a wind driven generator according to the control instruction and optimizing the frequency deviation of the whole hybrid power system. Compared with the prior art, the load frequency coordination control method has the advantages of being high in control accuracy, effectively improving the load frequency deviation of the hybrid power system and the like.

Description

technical field [0001] The invention relates to a method for controlling the load frequency of a power system, in particular to a method for coordinating the load frequency control of a wind-fired hybrid power system in which fans participate in frequency modulation. Background technique [0002] In recent years, the pollution of the environment by traditional power generation forms such as thermal power has become increasingly serious, and in the context of the rapid depletion of traditional energy sources, new energy sources such as wind energy and solar energy have attracted more and more attention and research. However, areas rich in new energy resources are generally relatively remote, such as wind resources in islands and solar resources in Xinjiang are very rich. Due to the inconvenient transportation in remote areas and isolated islands, the large power grid cannot provide continuous power supply to them. In this way, these areas will be more equipped to vigorously ...
