Assessment of the effectiveness of the use of alternative and renewable energy sources (RES): solar, wind, small streams.
The proposed technique has been tested in Tomsk region. The initial data of calculations are: cadaster of alternative and renewable sources of the investigated region, technical and economic parameters of components and equipment produced by leading Russian enterprises, State itemized estimate standards (SIES) on construction and installation works.
Criteria and the technique for assessment of the effectiveness of the use of alternative and renewable energy sources (RES) (solar, wind, small streams) are offered.
Three groups of indicators were used as criteria for the assessment of RES efficiency:
- social and environmental.
Assessment of the effectiveness of the use of alternative and renewable energy sources for electrification of objects without a centralized power supply is made on the basis of a comparative technical-and-economic analysis of all possible variants of electrification. The variants of power supply are taken into account not only from non-conventional energy sources but from conventional ones as well: construction of power lines and the use of diesel power plants.
The group of technical indicators includes only one criterion - the criterion of the project technical feasibility. The input data for determination of this criterion is the information on main technical characteristics of the primary energy source. In this regard, the criterion of the project technical feasibility on the basis of diesel power stations is always positive; when power is supplied from a centralized grid, it depends on the installed capacity of the power supply system P (kW) and the distance to the centralized power grid L (km); for a micro HPP it is determined from the minimum flow rate of water at the location of the station Vmin (m/s) and the minimal water discharge Qmin (l/s); for a wind power plant the criterion is the average annual wind speed at the level of the propeller hub Vav (m/s); for solar power plants it is the average daily irradiance E (kW×h/m2).
The group of economic indicators has two criteria: reduced annual costs per 1 kW of the installed power of a power plant and the cost of production of generated electricity.
Socio-environmental criteria of the effectiveness of the use of different types of power supply are as follows:
- potential threat to human life;
- availability of the fuel component;
- transfer of land;
- impact on birds and animals;
- acoustic impact and vibration;
- electromagnetic radiation.
