| Outline of Final Research Achievements |
In this study, a new method of building a dynamic load model for dynamic stability analysis was proposed. This method is as follows: First, inject some small electric power modulations of known pattern to power systems and measure the responses in the distribution system. Next, analyze the measured responses using system identification.
Simulation was performed with power system simulation software(PSCAD), and a dynamic load model was build and evaluated. In the simulation, the availability of the proposal method was confirmed. The model could reproduce the response of the stable system precisely. In addition to it, the trend of system becoming unstable could be evaluated with the proposal method.
