Special Issue Information

Dear Colleagues,

This Special Issue, entitled "Assessment of the Future Development of Renewable Energy", will present the results of completed and conducted research works, both in technical and soft (economic and social) terms, on the basis of which it is possible to try to set future directions for the development of renewable energy technologies as well as define its "dead ends".

Some examples of topics that contributions can focus on are as follows:

Current and future renewable energy technology application areas
The place of renewable energy technologies in the process of civic energy development – presentation of demonstrators
The current state of the RES technology market in different countries and the world in general
Comparison of conventional vs renewable energy technologies for system generation – presentation of interesting research results
Comparison of conventional vs energy technologies for micro-generation in technical and economic terms – presentation of interesting research results
Directions and development pace of RES technology
Technical barriers to the development of various RES technologies
Social barriers to the implementation of various RES technologies in the global energy sector
The role of renewable energy technologies in the future energy transformation of the global economy
The pace of R&D works at universities in the field of RES technology

Abstract

Nowadays, wind energy is receiving considerable attention due to its availability, low cost, and environment-friendly operation. Wind turbines are rarely placed individually but rather in the form of a wind farm with a group of several wind turbines. The purpose of this research is to perform studies on wind turbine farms in order to find the best distribution for wind turbines that maximizes the produced power, hence minimizing the wind farm area. Wind Farm Area Optimization (WFAO) is performed for optimal placement of wind turbines using elitist teaching–learning-based optimization (ETLBO) techniques. Three different scenarios of wind (first is fixed wind direction and constant speed, second is variable wind direction and constant speed, and third is variable wind direction and variable speed) are considered to find the optimal number of turbines and turbine positioning in a minimized squared land area that maximizes the power production while minimizing the total cost. Other research carried out in the past was to find the optimal placement of the wind turbines in a fixed squared land area of

2 km \times 2 km

. In the present study, WFAO–ETLBO algorithm has been implemented to get the optimal land area for the placement of the same number of turbines used in the past research. For Case 1, there is a significant reduction in land area by approximately 30.75%, 45.25%, and 51.75% for each wind scenario, respectively. For Case 2, the reductions in land area for three different wind scenarios are respectively 30.75%, 7.2%, and 7.2%. For Case 3, there is a reduction of 7.2% in land area for each wind scenario. It has been observed that the results obtained by the WFAO–ETLBO algorithm with a significant reduction in the land area along with optimal placement of wind turbines are better than the results obtained from the wind turbines placement in the fixed land area of

Case Study of Using the Geothermal Potential of Mine Water for Central District Heating—The Rožná Deposit, Czech Republic

Abstract

This paper analyzes the possibility of using the thermal energy of discharged environmentally friendly mine water for the heat supply of a selected locality. There are few cases of industrial use of geothermal water in the Czech Republic, but mine water has never been the source. Based on this fact, an analysis of the usability of mine water at the Rožná I Mine was carried out. The analysis showed that the energy output of this pumped water was sufficient for the selected location of the municipality of Dolní Rožínka, where long-term annual average consumptions are at a level of 4350 GJ. The theoretical maximum output of this source is calculated as 837.4 kW; therefore, it exceeds the output required to satisfy the energy needs of this location several times over. Based on this input information, a technical and economic model of the heating system installation project was developed with three options. The case study aimed to find and propose an optimal alternative solution to replace the current unsatisfactory state of heat supply in the village of Dolní Rožínka. In the final part of this paper, the most optimal option is identified by a comparative method, which replaces the existing central district heating based on the production of heat energy from natural gas, i.e., fossil fuels. This study was motivated by a strategy to replace fossil energy sources with renewable energy sources wherever conditions are suitable. Full article
