Dispersed Renewable Generation In The Power Supply System Of An Industrial Enterprise: Technical Feasibility And Economic Effectiveness
Keywords:Effectiveness, energy potential, integration, power supply systems, renewable energy resources, solar energy, wind energy
This paper is concerned with the possibility of using renewable energy sources for power supply to an industrial enterprise (a mechanical plant). We assessed the climatic conditions of the area and explored if it is possible to install renewable energy facilities (solar panels and wind turbines) at this plant. The assessment of climatic conditions in Irkutsk revealed that the use of wind turbines is not reasonable due to the weak wind activity in the city. However, this area has a relatively high potential of solar energy. The paper presents an in-depth analysis of the integration of solar panels into the power supply system of a mechanical plant. Their actual output depending on solar activity was calculated. Based on the area of the buildings roofs, the number of solar modules, inverters and other equipment pieces connected to them was calculated. The payback period of installed equipment was determined to assess the economic effectiveness. According to the assessment results, the economic effectiveness of their use is currently quite low. However, with the expected reduction in the equipment cost and an increase in electricity prices, renewable energy sources will become more cost-effective in the future.
