Design of solar power plants with hybrid systems

Abstract

The design of hybrid power plants aims to provide alternative solutions to the community in the event of a power outage. This solar power generation system utilizes solar panels that have the function of converting sunlight energy into direct electrical energy which is used as the main source in battery charging. In a hybrid solar power plant system that is made equipped with a logger system that stores data about temperature, current, voltage on the solar panel, battery percentage, output power at the load, charging source and the power used at the load. From the results of the design and testing of the hybrid charging system, the main power source of the solar panel, if the battery power is less than 40%, the charging system moves to PLN (the state electricity company) and when the battery power is above 50%, the charging from the PLN will be turned off, at Auto Transfer Switch (ATS) system will be active if the power from the PLN goes out, the relay will move the PLN power to battery power for 3 seconds due to the start of the inverter, if the PLN power is on, the power from the inverter will move to PLN directly with no pause.
