Abstract
The Republic of Kazakhstan has significant deposits of fossil fuels and is one of the largest energy producers among the countries of Central Asia. At the same time, The Republic of Kazakhstan is one of the richest countries of the world in terms of renewable resources, evaluated to over 1000 billion kWh/year. The application of therenewable energy sources (RES), both on a large scale and at the level of a single household, ensures the transformation of the energy system to a “green state”. However, these initiatives should be substantiated by relevant supportive information to promote transformation of the country's economy to a qualitative ecological state.The paper covers developed multi-criteria decision-making system (MCDM) and software tools for processing of spatial heterogeneous data which could be applied for evaluation of the RES potential.The developed system serves to evaluate the potential of usable RES as it allows the assessment of a territory of the country in terms of installing photovoltaic and wind generators.A feature of the proposed MCDM is the use of an analytical hierarchical process (AHP) in combination with the Bayesian approach, which allows obtaining two complementary assessments of the territory areas. The method allows a rough estimate in an event of lack of data.The verification performed based on the available data on the installed solar and wind power stations shows that the system gives a relatively small root-mean-square error within 15%.
Highlights
IntroductionSince 2011 growth of production capacities at the expense of renewables constantly exceeded growth of production capacities due to use of the traditional power technologies based on use of organic fuel and nuclear energy
Renewable Energy Sources (RES) find more and more broad application in the world, both in centralized(grid), and in the small-scale distributed, autonomous and individual power generation for power supply and heat supply of end users.According to the Global Status Report on ‘‘Renewables 2018’’ Renewable Energy Policy Network for the 21st Century, an increase in global energy potential in 2017 for 70% was reached due to the application of renewable energy technologies.The associate editor coordinating the review of this article and approving it for publication was Chang Choi.Since 2011 growth of production capacities at the expense of renewables constantly exceeded growth of production capacities due to use of the traditional power technologies based on use of organic fuel and nuclear energy
In the current implementation of the system, several sets of layers are loaded into the system, which are necessary for decision-making in deployment of renewable energy generators
Summary
Since 2011 growth of production capacities at the expense of renewables constantly exceeded growth of production capacities due to use of the traditional power technologies based on use of organic fuel and nuclear energy. As a result of it the general power of the power plants, the renewables using new technologies of use (without large hydroelectric power stations), exceeded 1200 GW in 2018, and the general rated capacity of power plants in the world is about 5500 - 6000 GW. The main participants of the world sector of renewables are wind turbines (about 550 GW), solar power stations, generally photo-electric (about 500 GW), biofuel power plants (more than 100 GW) and geothermal power plants (about 13 GW). The highest average annual rates of gain of input power are shown by solar energy - more
