Recently smart energy management systems (SEMS) have been developed extremely fast. The significant methods facilitate SEMS to sustain system scheming via demand responses, possibly together with peak shaving and load changing as well as a few additional services. This paper reviews the thought of SEMS and looks into its environment. It highlights the SEMS most important apparatus and moderately analyzes a different technical approach. In adding together discuss a number of the concern and challenge as well as suggests a framework for prospect systems.

This article deals with the power flow control in a hybrid power system, which is composed of a fuel cell, photovoltaic system and a super capacitor. The super capacitor has been employed with an aim to ameliorate the performance of the hybrid power system. In addition, it takes into account the energy fluctuations of photovoltaic energy sources and the slow dynamic of the fuel cell. Each source is connected to a DC/DC converter and their outputs are connected to a common DC-link and they supply a DC load. Furthermore, an energy management algorithm has been carried out in order to commonly share the power between the sources and the load. The proposed energy management method shows its flexibility, and an efficient energy conditioning between different sources is guaranteed in case of multi-source system. The main originality of this work lies in the use of AC-link partial resonant DC–AC converter topology to interface hybrid system and to inject the excess of energy to the grid. In this article, the system description, the control and the modeling of DC/DC converters and the AC-link converter are provided. Finally, simulations under Matlab/Simulink are shown in order to validate the effectiveness of the proposed control strategy and the energy management algorithm. An implementation on real-time using dSpace 1104 is presented to illustrate the feasibility of the proposed control strategy.

In order to enhance navigation safety and promote environmental protection, this paper takes the problem of energy management in a ship-integrated energy system into consideration. According to the characteristics of navigation, an intelligent ship energy management model, simultaneously considering the social and economic benefits, has been proposed. Meanwhile, this paper analyzes a distributed optimal scheduling problem which considers renewable generation devices and an energy storage system. Combined with an electricity-power system and thermal-power system, we propose an optimal scheduling scheme to accurately meet the actual load demand based on the pre-results analyzed by the ensemble learning short-term load forecasting algorithm. In addition, the related stability analysis is given. Further, a series of simulation results have been presented, which denote that the proposed load forecasting algorithm can accurately analyze the short-term load demand trend, and the proposed optimization algorithm can effectively coordinate economic and environmental protection.
