In this paper, a class of mixed H2/H∞ controller is designed for an energy router (ER) within the scenario of an energy Internet (EI). The considered ER is assumed to have access with photovoltaic panels, wind turbine generators, micro-turbines, fuel cells, diesel engine generators, battery energy storage devices, flywheel energy storage devices, loads, and other ERs. Two types of control targets are considered. First, due to the access of large-scale renewable energy sources, the DC bus voltage deviation within the ER system shall be regulated. Second, an optimal energy management strategy shall be achieved, such that the autonomous power supply-demand balance within each ER is achieved with priority and the rational utilization of controllable power generation devices and energy storage devices are realized. When these objectives are considered simultaneously, the control issues with respect to ER is formulated as a mixed robust H2/H∞ control problem with analytical solutions provided. Several numerical examples are given, and the feasibility and effectiveness of the proposed method are demonstrated.

Battery Energy

Frequency oscillations due to large load disturbance can be effectively damped by fast acting energy storage devices, because additional energy storage capacity is provided as a supplement to the kinetic energy storage in the moving mass of the generator rotor. The energy storage devices share the sudden changes in power requirement in the load. This paper deals with the concept of Load Frequency Control (LFC) in a deregulated power system considering Battery Energy Storage (BES) system. Time domain simulations are carried out to study the performance of the power system and BES system. The performance of the power system under realistic situation is investigated by including the effects of Generation Rate Constraint (GRC) and governor Dead Band (DB) in the simulation studies.

A detailed substantiation of the use of electric energy storage devices in the presence of generators on renewable energy sources in the power supply system is given. The dependence of the storage parameters on the composition and priority of generation in the system is investigated. The solution of the problem of determining the parameters of electricity storage devices by means of purposeful simulation of generation parameters is considered. The results of the choice of power and capacity of the energy storage using technical and economic indicators are shown. Optimal parameters of electric energy storage devices as one of the most important means of ensuring the activity of isolated power supply systems together with selection of generating devices are determined. The results of calculations of capacity of renewable energy sources in isolated power supply systems in combination with classical energy sources are given. The necessity of using the principle of activity of the distribution electric network and the possibility of its realization is demonstrated. The optimal storage capacity as a function of the share of renewable generation, the non-integrated energy produced by renewable sources and the total storage capacity are plotted for several isolated systems. The main points of the used model of the power supply system of isolated networks are given. In the studied isolated power supply systems, wind power plants and solar power plants, which have significant unpredictability of generation, are used as generation based on renewable energy sources. The problem of undersupply of electricity to the grid by stepwise increase of generation is analysed. The results of the multi-step selection of power and energy consumption of electricity storage are determined by technical criteria.

End Use

Renewable energy resources have been investigated as alternatives to fossil fuels. Though the energy density of these renewable sources is not comparable to the fossil fuels, their abundance make them highly interesting. There are three main steps in the renewable energy utilization: harvesting, conversion, and storage. Thus, after harvesting renewable energy, storing this energy is an important aspect for its large-scale end use. Considering the fact that the energy is a basic need for life on earth, there has been a strong scientific temperament towards the renewable energy utilization. The electrical energy storage maintains the key to promote the use of renewable energy. Among the storage devices, the rechargeable lithium ion batteries (LIBs) are the most promising energy storage devices. Among various cathodes proposed for LIBs, the most promising one is the spinel lithium manganese oxide (LiMn2O4). Its non-toxicity, low cost, abundance, and ease of synthesis, besides being environmentally friendly, make it suitable for next generation green LIBs.
