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.

Energy storage units (ESU) and distributed generation (DG) plants including those using renewable energy sources can be used to develop isolated power supply systems (IPSS) and enhance their reliability. Operation of DG plants in the IPSS requires to consider restrictions for consumers maximum load, as well as effects of abrupt load increase or load shedding on the generating plants. These problems can be resolved using ESU and intelligent technologies for DG plants control. The paper considers IPSS of an industrial facility with turbogenerator plants (TGP), wind power plant (WPP) and high-capacity ESU for which fuzzy control systems and prognostic controllers were used. The simulation was performed in the MATLAB system using the Simulink and SimPowerSystems software packages. Normal and emergency modes were studied in IPSS with TGP, WPP, and high-capacity ESU. The simulation results indicated that combined use of high-capacity ESU and prognostic controller of TGP generator rotor speed allows to ensure stability and survivability of IPSS enhancing its damping properties. The auto-prognostic controller of the TGP generator, which does not require special adjustment, provides high quality indicators of the IPSS control in all considered modes.

The chapter considers the factors that affect the incomplete use of power. The analysis and systematization of accumulating systems on the types of accumulated energy, on the processes occurring during storage, types of devices and types of generated energy is performed. Each of the possible ways of accumulating energy is analyzed in detail. Various variants of conformity of schedules of change of a consumed load within a year and a total resource of solar radiation are considered. The analysis of the parameters of heat-accumulating materials and their classification depending on the material class, the way of heat accumulation and return, on the cyclicity of work, etc. are provided. It is shown that the level of temperature, the scale of the storage unit, and the necessary duration of heat storage determine the requirements for the construction of batteries and the choice of heat-storage substances. The prospects of research on the search for new ways of accumulating energy and technical means for their implementation are considered.

Energy storage technology offers a number of economic and environmental benefits. This paper provides an analysis of power grid backing up solutions with energy storage devices assuming that energy storage backing up can be generally more efficient for microgrids than conventional reserving options. Cost-effectiveness and a distance to a backup source have been accepted as criteria for comparing. For power supply systems of 200 AH, the energy storage backup efficiency has been proven by appropriate computations as reflected in this paper.
