The problem of power supply to remote consumers in the “Baikal-Khövsgöl” Cross-Border Recreation Area, associated with the high length and low reliability of power lines is discussed. The assessment of the modes of the power distribution grid showed that the introduction of new consumers in this territory will lead to unacceptable voltage deviations, even taking into account the installation of reactive power compensating devices. Since the area under consideration has a high solar energy potential, it is advisable to use distributed solar generation. The choice of locations and capacities of solar power plants is a multi-criteria optimization problem. Four criteria are proposed: total voltage deviation, total active power losses, reliability and capital costs for construction. An algorithm for multi-criteria optimizationis developed and implemented as a program in the MATLAB, which consists in sequential verification of the feasibility of installing additional power of solar power plants at the consumers of each of the substations under consideration. For each variant, the electric grid mode is assessed using the Power system analysis toolbox program. Solutions for the choice of locations and capacities of solar power plants are obtained, providing high scores by criteria in accordance with the given criteria importance coefficients.

Express Methods

The chapter presents express methods for estimating the solar energy potential at a given point on the basis of combining the solar radiation daily profile application method under clear skies and actinometrical data of the NASA electronic base. Such a new approach including the climatological conditions of the region, significantly reduces the calculation time, and improves the accuracy of the decisions with a minimum of initial data. For the speed and convenience of calculations based on the proposed methodology, it was implemented in the form of a computer program. The article also analyzes the influence of spatial orientation on the maximum electricity produced during the month, season and year and it reveals that the use of an optimal inclination angle for the specified periods of time makes it possible to realize the existing solar potential of the region at the same capital expenditures.

The solar radiation and energy potential in Serbia is 30% higher than in Central Europe, and the intensity of solar radiation is among the highest in Europe. Specifically suitable are the condition for usage of solar energy in southeast Serbia where the annual average of global radiation on a horizontal surface amounts to more than 4.2 kWh/m2 a day. This chapter discusses four photovoltaic solar power plants, two having been installed in the territory of the city of Leskovac and two in the Bosilegrad territory. The research is based on geographical location of solar power plants, orientation, and inclination of the panels in respect to the horizontal surface. All the processed solar power plants have the capacity 30-40 kW. The chapter is projection of two years of researching and measuring data on the initial investments in order reach profitability and investment return period. The solar power plants that have fitted angle of 33° (Fortuna) give higher production of electric power than in those panels that have angle inclination of 10° (Domit).

Solar Power Plants

The expediency of using several sources of information on climate factors for estimating the potential of wind and solar energy is substantiated. Specific features of the methodology and developed software for estimating the generation of energy by wind power plants based on weather stations open access data are considered. The possibility of taking into account the results of aerodynamic modeling of the flow of the terrain by the wind flow is realized. The methodology is implemented in the form of a computer program called Wind-MCA. It includes a module for analyzing wind power potential, a module for analyzing wind turbines, an economic analysis module, and a multi-criteria analysis module. Specific features of the methodology and developed software for estimating the generation of energy by solar power plants based on data on the transparency of the atmosphere, temperature and cloudiness are considered. The technique is implemented in the form of a computer program called Sun-MCA. The estimation of the wind energy and solar energy potential of several settlements in the central zone of the Baikal region is carried out taking into account the climate change in the region.

Renewable energy is a solution for electricity generation for cleaner and green energy. The aim of this paper is to find the energy potential of India in terms of sources, per-capita energy consumption and the main potential consumers. Comparing consumption of fossil fuels and Renewable energy sources (RES) of India in 2019 and 2020 and finally to find whether there is any change in energy generation of two solar power plants in different geographical location of India with the help of independent t-test statistics. In this paper two statistical analysis are proposed. One is the statistical analysis of installed capacity, generation and consumption of fossil fuels and renewable energy in India. Other one is the statistical analysis of two solar power plants located at different geographical locations in India. From the statistical analysis it is found that, installed capacity of coal, RES and hydro is increased in 2020 as compared to 2019. Total demand in January 2020 is 2,77,140.33 MW whereas total installed capacity is 3,71,126 MW, this means that installed capacity is more but are not in running condition. From the statistical analysis of two independent solar power plants it is found that solar power plant-1 generates more energy but with high conversion loss hence poor efficiency.
