Abstract
The expansion of renewable energies is progressing strongly. The influence on the power supply networks by the variability of the infeed must be met with new concepts. In this paper, we investigate the possibilities of integrating microgrids as a cooperating unit in the power supply network to support further expansion of renewable energy sources (RES) power plants. In this paper, a differentiation of microgrids from similar network structures is established, and a classification of proposed groups is made. Then, after the description of the simulation of the components in a microgrid, with practical advice, an example model is shown, which aids the dimensioning of the components within a microgrid to achieve a specified goal.

The politically-promoted development of renewable energy sources (RES) in recent years is enormous
The simulation-based approach is applied to fully simulate a complex microgrid connected to a local medium voltage (MV) distribution grid, including charging stations and Electric vehicles’ (EV)
The main contributions of this paper lie in the presentation of practical considerations related to the operation and modelling of microgrids, the design of a complete framework for simulation and the optimization of a microgrid composed of photovoltaic generation, battery storage, combined heat and power (CHP) and an electrical vehicle charging pool
Summary
The politically-promoted development of renewable energy sources (RES) in recent years is enormous. The simulation-based approach is applied to fully simulate a complex microgrid connected to a local medium voltage (MV) distribution grid, including charging stations and EVs. Research related to the control of microgrids’ components, presented in [13,14], shows that the simulation-based approach is able to facilitate the evaluation of smart grid- and EV-related communication protocols, control algorithms for charging and the functionalities of local distribution grids as part of a complex, critical cyber-physical system. The main contributions of this paper lie in the presentation of practical considerations related to the operation and modelling of microgrids, the design of a complete framework for simulation and the optimization of a microgrid composed of photovoltaic generation, battery storage, combined heat and power (CHP) and an electrical vehicle charging pool.
