Description
Summary:The first system protection demonstration project-Eastern China emergency frequency control system is introduced in detail. Then, the specialty of flywheel energy storage in frequency control is researched, and the analysis result show that the flywheel energy storage can be used in emergency frequency control. In addition, mathematical model of frequency estimation is proposed based on the frequency characteristics of generator and load. Thus, the frequency response can be calculated after power loss that caused by DC block. At last, a method of emergency frequency control with Multi-resources coordination is proposed based on the curve of frequency response.
