Renewable energy is an indispensable source at present, where many resorted to the use of renewable energy, but there is a problem as a discontinuous source, according to climatic conditions and the surrounding environment. Thus, researchers worked on a new system to control climate changes affecting the production of renewable energy, which is a Hybrid system where Uses more than one source to maintain energy continuity and uses an energy storage system. In this paper, three different sources of renewable energy (solar energy - wave energy - fuel cell energy) are integrated and an energy storage system was used. Buck-boost converter circuits were used in the three sources and connecting them to the DC busbar. The inverter was used to convert from DC to AC to supply the load. A new integrating system was used to connect three sources and store energy at the same time from the surplus energy. When there is a problem with one of the sources, the battery bank feeds the system directly. The simulation model of the whole hybrid power system is implemented using Matlab / Simulink. It is clear from the results that the controller has high efficiency and accuracy and has the ability to integrate more than two sources.
