Abstract:

Purpose. Reducing active energy losses at industrial enterprises by improving the efficiency of renewable energy sources integration through the creation of an energy-efficient innovative power grid.

Methodology. The work used methods of system synthesis and computer modeling to calculate active power and voltage losses in power grid components.

Findings. The use of the proposed structure of an innovative power grid for industrial enterprises significantly reduces power losses in workshop grids and unwanted power flows in inter-transformer cable lines, as well as solving the problem of electromagnetic compatibility of the grid’s loads.

Originality. The paper proposes a scheme for an energy-efficient innovative power grid for industrial enterprises, according to which consumers and energy sources are connected to the corresponding local AC grids of high-quality and low-quality electricity, as well as a DC grid that combines the two above-mentioned grids into the enterprise’s power supply system. The use of this approach significantly reduces the cost of integrating renewable energy sources and solves the problem of electromagnetic compatibility with regard to the elements of the enterprise’s power grid.

Practical value. The use of an innovative power grid scheme for industrial enterprises does not lead to additional unwanted power flows in inter-transformer cable lines if renewable energy sources are involved, and also reduces active power losses in workshop grids. The results of a comparative analysis showed that when using the proposed innovative power grid scheme for an industrial enterprise, daily active power losses in its workshops are reduced by more than 40 %.

Keywords: power grid, power losses, renewable energy sources, power quality
