Modeling and Simulation of Renewable Energy Sources in Smart Grid Using DEVS Formalism

Because of safety, economical, and environmental reasons, the community of power systems is being working on developing a new and clean power grid, the smart grid. Smart grid infrastructure brings together renewable energy sources with information technology domain to find optimal and clean power generation, storage, and consumption. The first step in designing an intelligent power and data infrastructure, is to model and simulate the different components of smart grid in order to make accurate design decisions. In this paper, a modeling and simulation approach in the Discrete EVent System Specification (DEVS) environment is proposed. The approach models four main components in smart grid which are: photovoltaic arrays, wind turbines, storage devices, and load demand. Also, other components are being developed as well and will be discussed. Real wind speed and solar radiation profiles were used in the simulation. The tool results of the maximum amount of stored power and the power shortage are used to help the power system designer at a specific location in making decisions on the capacities needed for photovoltaic arrays, wind turbines, and storage
