Calculation of the Optimum Parameters of Electrical Energy Storage and Generating Sources in Autonomous Local Electrical Systems

The paper presents the issue of determining the most the optimal parameters for electrical energy storage and generating equipment in autonomous local electrical systems (ALES). The substantiation of the role of energy storage devices in the presence of renewable energy sources in autonomous local electrical systems with a stochastic mode of operation is given. The main provisions of the used model of electrical systems are given. The dependence of the parameters of the energy storage device depending on the composition of generating capacities has been studied. The implementation of the problem of determining the parameters of electric energy storage devices by the method of purposeful simulation is considered. The results of the multi-criteria choice of power and energy intensity of the electric energy storage are substantiated. A mathematical model has been developed for determining the optimal parameters of electric energy storage devices for autonomous local electrical systems using mixed integer programming with optimization and taking into account economic indicators. The main provisions of the model used are considered. The dependences of the parameters of electric energy storage devices on the composition of the generation of autonomous local electrical systems have been studied.
