In this paper, we describe a method of modeling the global solar irradiance on a clear sky. The proposed method is based on astrological phenomena, with which we can estimate the global solar irradiance of the few days, several months, and some years. To estimate the irradiance with high accuracy, it is necessary to calculate the solar radiation outside the Earth's atmosphere taking into account the...
We have been developing a high-speed simulator and micro-grid emulator for real-time energy management system. In this paper, we describe our new fast simulation model for PV system that will allow us to simulate 24-hour data in less than 5 sec. We use this simulator to make estimations and verify our management strategies. We have proposed a hybrid DC/AC micro-grid system in our previous work. The...
This paper presents a simulation model of green energy devices, which is developed for analyzing energy balance of a micro-grid and for optimizing its management. Several renewable energy based electricity production and storage are modeled and analyzed in the making of strategies for sustainable micro-grid management. In this study, two different simulation models are described, which call a “long-term...
