Abstract:

The paper presents a research on the assessment of cost-effectiveness of an hybrid electric power system including photovoltaic modules, wind turbines, wood-fired biomass gasification power plants, batteries for electric energy storage, and diesel power plant. An optimal structure of the electric power system is determined for different climatic zones of Russia. The energy sources are ranked with respect to their efficiency, by imposing constraints on capacity of individual plants (ban on commissioning). The study demonstrates a considerable economic effect of the renewable energy sources for many considered variants. However, the most preferable option is the combined use of different renewable energy sources: wind turbines, photovoltaics and a biomass gasification power plant.
