Modeling of the Renewable Energy System of an Net Zero Energy Community

This paper introduces our research in modeling the renewable energy system of Historic Green Village, which is a real-world net zero energy community (NZEC) in Florida. We will first introduce the renewable energy system that serves the Historic Green Village and the design of our modeling framework. Then we show the implementation of Modelica models for the renewable energy network, including the renewable energy generation by the photovoltaic(PV) panel, energy consumption of buildings, and the interface between the power grid and the NZEC. After that, we will present simulation results and compare them with the onsite measure data from the Historic Green Village. The results show that the Modelica models are able to reveal the dynamic behaviors in renewable energy network in NZEC. That information can be used for future research in the optimization of NZEC operations.
