Improving reliability of power supply facilities in agro-industrial sector

Abstract

The analysis of energy efficiency of territorial network organization (TNO) of the Ministry of Energy and agricultural company (AC) with renewable energy source (RES) on the balance of TNO or AC was carried out. It is shown that when evaluating the energy efficiency of technical facilities, it is possible to use the efficiency factor, and when evaluating the technologies of product manufacturing, the energy intensity of product manufacturing can be used. If RES is on the balance of TNO, the efficiency of TNO is determined by the additional gross income (GI) received from the electric power (EP) sales of RES and the reduction of EP losses in its transmission line (PL) of the centralized power supply system (CPSS). AC buys all the necessary EP, for agricultural production (AP), from TNO. If the RES is on AC balance sheet, the TNO efficiency is determined only by the reduction of EP losses transmitted through the CPSS PL. In this case, TNO loses part of the gross income from the reduction of the amount of EP purchased by AC, by the amount of EP produced by RES. The energy efficiency of agricultural production (AP) in AC increases because the energy intensity of AP production is reduced by the EP additionally received from RES.
