Developing small energy, based on local energy sources, is top priority and challenging industrial trend today. According with the last International Energy Agency data (further, IEA) using renewable energy sources has been increasing comparable to other sources. Using alternative energy sources is expanding geographically every year. According to forecasts of IEA 75 countries will have wind power plants in 2018. Solar batteries of more than 100kW will be used in 65 countries, but now only 30 countries. Total power capacity of electricity from alternative energy sources will increase from 1580kW in 2012 to 2350kW in 2018. In 2016 renewable sources will be second to coal, edging out gas and atom energy. The major renewable energy source is still hydro-energy, however, the most significant increase involves wind energy and solar batteries, i.e. from 4% in 2011 to 8% in 2018 (doubled proportion).
Even today many populated areas in Tomsk Oblast centralized electric power supply. The situation is the same for many and many areas of Russia (according to the latest data not less than 70% of the Russian Federation). In remote villages and towns electricity is produced by diesel power stations (DPS). In this case, the application of solar -wind power stations in remote areas would be the most effective and rational solution, as connecting a remote populated area to centralized electric power supply would be not only technologically difficult (sometimes even impossible) but also exclusively expensive.
One of the pilot projects in developing local power economy would be the construction of solar-wind power station (SWPS) in Alataevo, Parabelsk region. The project was approved by Tomsk Oblast Administration as its implementation would be the proof of applying such energy source and its possible development.
The project involved changing over from diesel power station to autonomous solar-wind power station to supply electric power in Alataevo and Narim.
This combined electric power station included solar batteries, battery accumulator (stabilizing unit), wind generator, as well as electronic unit, embracing controlling system (controling batteries), charging unit and invertor, converting DC to AC -220W and frequency- 50Hz. Electric power loading and accumulator charging occur if the sun is shining and the wind is blowing, but visa versa, at night or in storms, the loading is through the accumulators. Applying two wind generators recovers 75% of necessary energy involving minimum investment and operating costs. SWPS capacity is sufficient for all the demands in these two villages. According to expert calculations payback period will be 3-4 years.
If obtained energy effect will coincide with presupposed energy capacity, then it would be possible to further this experience throughout Russia.
The project was ceritified in autonomous institution “Government Expertise of Project Documentation Agency of Tomsk Oblast” OGAI “TOMSKGOSEXPERTISE” (positive expertise № 70-1-5-0004-13 dated 14.02.2013).
At present an analogous project “Wind-diesel power station of 100kW supplying autonomous power for Novonikolskoe, Aleksandrovsk region” is being certified in this organization. This project involves the development of a wind park of 5 wind generators which would decrease the costs on fuel and its delivery and increase the operating resource of existing diesel units- additional sources for electric power supply in Novonikolskoe.
Besides, our experts are developing project documentation on “Solar-wind power station of 250kW supplying autonomous power for Lukashkin Yar, Aleksandrovsk region.” The project includes the following stages:
Stage 1- establishing a meteorological station for monitoring;
Stage 2 — monitoring all major climatic parameters and techno-economic feasibility;
Stage 3 — design-estimate documentation.
A meteorological station was established to observe wind velocity and direction and measure sun ray magnitude. A software program package was installed for remote monitoring and archivation of obtained data. Thus, 24-hour monitoring of basic climatic parameters on the construction site (wind energy, insolation) throughout summer, fall, winter and spring was provided and starting from project contract execution to site construction.
However, it should be stated that Russia today has the last position in the market of alternative energy sources comparable to countries of equal status. At the same time Russia has all possible inexhaustible opportunities in this field. Obtained experience in developing and executing such projects would be priceless and highly-effective in solving arising technical problems and would promote knowledge accumulation in this field and further finding solutions and enhancing existing energy standards, as energy efficiency of alternative sources to 50% would depend on not only the capacity of the source itself but also technologically designed stations and sites.
