Now a days non pollution power production is popular because of less pollution and eco-friendly. This paper presents a new system configuration of the front-end rectifier stage for automatic energy management system of renewable energy source. In today’s technology driven world electricity is one of the foremost things for our day-to-day life activities. As we all are oblivious of the fact that the renewable sources of energy are depleting at a lightning-fast rate. So, it’s time for us to shift the focus from conventional to non-conventional sources of energy to produce electricity. The output of the electricity produced by non-conventional sources is less than their counterparts. Renewable sources do not have any detrimental effect on the environment. Solar- wind and main automatic energy management system of renewable energy is basically an integration of solar plant and a wind energy plant. It will help in providing the uninterrupted power supply. As during bad weather conditions, the production can be shifted from one source to other with the help of a microcontroller. A microcontroller ensures the optimum utilization of resources and it also increases the efficiency of the combined system as compared to the individual mode of generation. It helps in decreasing the dependence on one single source and makes the system more reliable. The system can be used for both industrial and domestic applications. This configuration allows the two or more sources to supply the load depending on the availability of the energy sources and priority.

In order to carry out the maximum use of unstable renewable energy, progress of energy storage technology is indispensable. Hydrogen which is one of the storage media has a high possibility of becoming a leading energy career. We proposed the totalized hydrogen energy management system (THEM-System) that consists of fuel cells, water electrolyzes, metal hydride tanks and their auxiliaries. Firstly this paper presents the developed numerical analysis model of metal hydride tanks. From the comparison between calculated results and experimental results, it has been confirmed that the numerical analysis calculation can estimate reasonably the dynamics of the metal hydride tank in the 5 kW class system, and moreover, it has been confirmed that by using this model, the structure and the operation conditions of metal hydride tanks can be designed rationally for the THEM-System. Furthermore, Photovoltaic-Water electrolyzer system which performs suitable control in accordance with unstable weather conditions was introduced. Using this unstable hydrogen supply, the characteristic of the metal hydride hydrogen tank is also examined numerically and experimentally.

This paper proposes an enhanced energy management system (EEMS) for a residential AC microgrid. The renewable energy-based AC microgrid with hybrid energy storage is broken down into three distinct parts: a photovoltaic (PV) array as a green energy source, a battery (BT) and a supercapacitor (SC) as a hybrid energy storage system (HESS), and apartments and electric vehicles, given that the system is for residential areas. The developed EEMS ensures the optimal use of the PV arrays’ production, aiming to decrease electricity bills while reducing fast power changes in the battery, which increases the reliability of the system, since the battery undergoes fewer charging/discharging cycles. The proposed EEMS is a hybrid control strategy, which is composed of two stages: a state machine (SM) control to ensure the optimal operation of the battery, and an operating mode (OM) for the best operation of the SC. The obtained results show that the EEMS successfully involves SC during fast load and PV generation changes by decreasing the number of BT charging/discharging cycles, which significantly increases the system’s life span. Moreover, power loss is decreased during passing clouds phases by decreasing the power error between the extracted power by the sources and the required equivalent; the improvement in efficiency reaches 9.5%.
