The diffusion of renewable sources of energy has been increased because they reduce the environmental influence and meet the increase in demand of energy. The key feature of the renewable source of energy is their changeability and irregularity. These draw backs are overcome by combining the non-conventional sources through storage and back up. However the incorporation of renewable sources of energy makes the system more complex in respect of energy sharing, control and analysis. The main objectives of energy management configuration are to ensure the maximum exploitation of renewable sources, continues power supply to the load, lessen the rate of energy production and increase the steadiness of the system. To accomplish these purposes efficient and fast control techniques are required which are proficient of handling information perceptively and captivating acute decisions vigorously inside the operative limitations. This paper presents an explicit review of energy management approaches currently existing and those now in research for the smooth process of hybrid system with renewable sources.
