Human Machine Interface (HMI) serves as a bridge for operators to understand the processes that occur in a production system. Without the HMI, operators have difficulty in monitoring and controlling the production system. It serves to facilitate the operator in monitoring the plant, plant control, plant handling, and access historical data either for the whole process or each of the existing equipment in the process. This paper presents an investigation on the simulation of wind and solar power hybrid systems through the human machine interface using software InTouch Wonderware. This simulation features a visualization of the process of charging wind power and solar power in a hybrid and charging process on battery and load. The simulated investigation results show that each power source produces a maximum of 100 KW, the total power charging is the sum of the two power sources, which is a maximum of 200 KW, the charging capacity of the battery is a maximum of 100 KW, and the duration usage at the load is a maximum of 100 KW converted to 10 hours load usage. With this HMI, operators can easily control the hybrid system in the power charging field.
