A hybrid microgrid, combining wind and solar energy, for remote locations. It suggests the idea of enhancing customer understanding through a virtual tour using a 3D model created with Dassault Systemes' 3DEXPERIENCE platform. The platform employs Dymola, a tool for modeling complex systems. The design of a stand-alone microgrid that integrates a 3kW solar system and a 5kW wind system, connected in parallel to a 100Ah battery. The DC power from the battery is converted to 230V, 50Hz AC power using a single-phase full bridge inverter, and the output is tested for both resistive (R) and RL loads. A 3D model is created for the entire microgrid system.
Objective
Objective
Design of solar PV and wind energy system of the project using Dymola: Design involves selecting suitable type of solar panel and wind turbine to get best possible efficiency.
Sizing wind/PV the microgrid using Dymola: Sizing includes iterative simulations to be done to decide the number and capacity of PV panels, wind turbines, battery storage.
Design and simulate suitable power converters: Power converters are integral parts of PV and wind generation system to maintain a constant voltage and frequency. Power converters with closed loop control will be developed using Dymola.
3D Model of PV/Wind microgrid using 3DEXPERIENCE: A complete 3D model of the microgrid to give the users a virtual experience of the system.

Fig 1: Overview of Microgrid
The overview of the standalone PV/wind microgrid is shown in figure. Here solar and wind energy system both are connected to a dc bus. A battery is also connected to the dc bus to store the energy generated from the renewable sources.
Then the DC supply from the battery is converted to AC with the help of an inverter and finally given to the load.

3D Modeling
3D Modeling
The 3D modelling of the microgrid is carried out using CATIA software available in 3DEXPERIENCE platform. The 3D model of microgrid is built in two stages. In first stage, individual 3D parts are designed using part design software. In this software, initially 2D sketches of all parts are created and then they are converted to 3D parts with the help of several tools available in the software.
In the final stage all the 3D parts are assembled using assembly design software and the microgrid is built in the 3D environment. The assembled 3D model of microgrid is shown in figure 4.2. This model is then integrated with virtual reality, so that the newcomers can have better understanding about the area covering the microgrid.
PROJECT OUTCOMES
PROJECT OUTCOMES
A stand-alone microgrid combining solar and wind energy sources is designed and developed using Dymola. Here a 3kW solar energy system and a 5kW wind energy system are connected in parallel across a 48V, 100Ah battery to form the microgrid. Then the DC power from the battery is then converted to 230V, 50Hz AC power with the help of a single-phase full bridge inverter. By considering R load as 25Ω and RL load as 25Ω & 0.1H, the AC output from the microgrid is verified. Also an interactive 3D model of the solar-wind microgrid is successfully built using 3DEXPERIENCE platform.
