Abstract
The object of this study is the process of integrating industrial energy storage units (IESU)
into distribution electrical networks. Their connection helps reduce peak loads on the elements
of networks and improve the quality of voltage.
However, determining the optimal IESU capacities and their places of connection to networks is
associated with objective difficulties. It is necessary to apply comprehensive optimality criteria
and take into consideration active restrictions. In
addition, the trends in the development of distribution networks and pricing in the energy market
are partially undefined. The current study proposes the formalization of the problem of optimizing the placement of IESU in distribution networks and reports a new method to solve it. Its
application contributes to a reasonable definition of the volume of investments in the development of IESU, taking into consideration technical
restrictions on the part of distribution networks.
To solve the problem of multifactorial optimization of the energy storage system, the decomposition and method of ideal current distribution (for
electricity losses) were applied. It is shown that
this problem can be reduced to an iterative calculation of current distribution in the substitution
circuit of power grids with active resistances.
And, to take into consideration economic factors,
a technique to determine and adjust fictitious
resistances was devised. An optimization algorithm has been proposed that ensures a decrease
in the number of computing operations and an
increase in the reliability of obtaining an optimal
solution. Its application makes it possible to take
into consideration the dynamics of pricing, consumption, and electricity generation processes
over long periods. This contributes to the formation of sound design decisions on the connection
of IESU to distribution networks
