Visualization Technique of Smart Grid Simulator

Abstract

We have developed a visualization technique of smart grid simulator as a combination of graphics technology and power system simulation. Renewable energy is being widely and rapidly deployed worldwide, however, it may cause variations such as reverse power flow and voltage fluctuations. The main reason of the variation of photovoltaic generator is clouds in the sky. We've developed a cloud model by using graphical technology and utilize it for not only the visualization of the variations but also emulation of photovoltaic generators. We create the cloud model as the particle model whose statistical property can be adjusted to the measured irradiance data. Numerical experiments show that the statistical properties between the measured data and simulated data can be tuned similarly.
