Abstract
The existing methods for calculation electricity tariffs for enterprises are analyzed numerically. The efficiency of diesel generators use for power supply was estimated using a real object as an example. A methodology has been developed for choosing the optimal price category, based on the schedule for consumption of electrical energy of a particular enterprise, taking into account introduction of its own generation in the 0.4 kV network. It is shown how to get the maximum benefit using one of the most affordable and autonomous power sources, taking into account the peculiarities of tariff setting for electricity.
Highlights
In modern electric power industry, there is a problem of constant growth of electricity tariffs, under centralized electricity supply
We consider the choice of optimal price category and assessment of efficiency of using diesel generators in a 0.4 kV network using the example of a woodworking enterprise
The initial data provided by the enterprise include: - Volumes of electricity by feeder at hourly intervals for the billing period. - The voltage side on which electricity is being purchased
Summary
In modern electric power industry, there is a problem of constant growth of electricity tariffs, under centralized electricity supply. The introduction of own generation at industrial facilities is the most optimal solutions to the problem, both from practical and from economic points of view [1], [2]. As it is known, the main consumers of electricity are industrial enterprises, and a significant share of consumption is accounted by small and medium-sized enterprises, the installed capacities of which are in the range from several kilowatts to ten megawatts [3] - [5]. We take into consideration this category of own generation [5] - [8]
