This proposal is to investigate the basic theories and key technologies with regard to the dynamic regulation of frequency responses (viz., inertial response and primary frequency response) from wind turbines/plants, as well as its coordinated control with conventional synchronous generators, in power systems with highly-penetrated wind powers. Specifically, the main contents contain the following two aspects, viz., 1) the impacts of frequency responses from grid-connected wind power on the power system frequency characteristics and the electromechanical stress & structural loads in wind turbines are revealed, and the frequency control strategies and optimization methods available for wind turbines/plants are further proposed; 2) the interaction characteristics of dynamic coupling among wind turbines/farms and conventional synchronous generators to dynamic frequency in power systems are uncovered during frequency regulations, such that coordinated frequency control schemes between wind turbines/farms and synchronous generators are proposed. The outcomes of this proposal will provide.the theoretical basis and key technology support to the frequency stability as well as its assessment indicators’ establishing and improvement in power systems. This project and its accomplishment feature theoretical significance, urgent project requirements and promising applications, which, as a result, will promote research level in China up to the international forefront in the field of large-scale wind powers integrated into power systems.
