Abstract The purpose of this study is to optimize the operation of wind power generation-based standalone microgrid linking P2G technology.
Renewable energy sources, such as wind turbine, photovoltaic, etc., use natural energy as a power source, so the system operator could not control the power of the renewable energy sources. Failure may occur and damage such as power failure may occur if the facilities of the RES that cannot be controlled output increase and the balance of power supply and demand in the power system is not matched. In this study, insufficient power is supplemented by power supply using diesel generator, and excess power is supplemented by Battery Energy Storage System (BESS) and Power-to-Gas (P2G) technologies. In particular, P2G technology using hydrogen energy is mainly dealt with, and multi-objective optimization programming that satisfies both objective functions is interpreted based on pareto-front optimization by deriving the power limit of wind power generators and system costs incurred when building and operating microgrids
