Special Issue Information

Dear Colleagues,

The sun's energy, which reaches the Earth, is most widely used to generate heat and power, both separately and combined. Rapid population growth and urbanization lead to growth of the global economy, which significantly expands the global demand for clean water and energy, affecting sustainable development. Northern territories become more available due to climate change, but the Arctic and permafrost regions' eco-systems are more sensible when affecting pollutants. High transportation cost and other issues limit fossil fuels for heating, ventilation and hot water supply in northern territories. Using fossil fuels for energy generation exhausts the supply of non-renewable resources and damages environmental systems. The application of solar use in many countries was investigated, and global maps show the significant potential of this kind of renewable energy.

The duration of sunshine in northern territories, in some places, is very high, which is favorable for the use of photovoltaic systems or the use of solar energy for hot water supply. The sustainable development of northern territories is naturally associated with energy-saving and enhancement of energy efficiency by applied technologies and equipment, including clean and renewable energy. This current Special Issue focuses on the main problems faced when implementing solar energy in northern territories, which have their features. It is essential within the global energy transition and sustainable energy grids to reduce modern society's environmental pressure.

Abstract: The global climate changes on Earth unites virtually every country in an energy transition with the ultimate goal of achieving zero carbon emissions. The acceleration of the energy transition in the energy sector will become a defining social, political and technical problem of the 21st century and will largely be associated with the increase in the use of renewable energy sources, including the most affordable solar energy. The widespread use of solar energy in the northern territories is still limited and studied weakly. This work presents the results of an experimental study of the features of the operation of solar hot water supply systems built in the northern territories. The study was carried out on a hot water system supplied by solar energy. The heat substations were placed in the apartment buildings of Yakutsk City close to Arctic Circle. An experimental unit was built in Western Siberia close to Tomsk City. Experimental data on ensuring the elimination of freezing of the coolant in the hydraulic circuits of the collectors at night were investigated. It was concluded that the icy surfaces reduce the thermal performance of the system by 30%. The optimal operation of a hydraulic pump and/or a regulating valve allows using water as a heat carrier and excludes freezing in the hydraulic circuits of collectors at negative outside temperatures. It was found that the decrease in the thermal performance of the surfaces of the evacuated tube collectors contaminated with snow is from 16.4% to 23.1%.

Title: Simulators for Designing Energy Efficient Power Supplies Based on Solar Panels for Autonomous Objects

Affiliation: Tomsk Polytechnic University
Abstract: Boosted interest in highly efficient power supplies based on renewables requires involving simulators during the designing stage. It is especially relevant for the power supplies that operate in harsh environmental conditions of Northern Territories. Modern solar panels based on Si and GaAs possess relatively higher efficiency and energy output. To save designing time and cost system developers use simulators for the solar panels coupled with the power converters that stabilize the output voltage and ensure the proper output power quality to supply autonomous objects, namely, private houses, moderate power (up to 100 kW) industrial buildings, submersible equipment, and satelites. It is crucial to provide a valid I-V curve for the solar panel operating in different operating modes and ambient conditions, namely, consumed power, temperature, solar irradiation, etc. This paper considers the solar panel simulators topologies and suggests the state-of-the-art solutions. These solutions are based on subordinate control principles involving buck converter topologies. Moreover, we employ the electric load simulators to provide the ground testing for the power supplies. This class of simulators are based on a boost converter topology with the current feedback. The developed simulators provide full-scale ground testing both for solar panels and power supplies operating in harsh environmental conditions and may serve as a base for developing a product line of energy efficient power supplies based on solar panels for autonomous objects.

Abstract: Boosted interest in highly efficient power supplies based on renewables requires involving simulators during both the designing stage and the testing one. It is especially relevant for the power supplies that operate in harsh environmental conditions of Northern Territories. Modern photovoltaic (PV) panels based on polycrystalline Si and GaAs possess relatively high efficiency and energy output. To save designing time and cost system developers use simulators for the PV panels coupled with the power converters that stabilize the output voltage and ensure the proper output power quality to supply autonomous objects, namely, private houses, moderate power (up to 10 kW) industrial buildings, submersible and other equipment. It is crucial to provide a valid I-V curve for the solar panel operating in different operating modes and ambient conditions, namely, consumed power, temperature, solar irradiation, etc. This paper considers the PV panel simulator topologies and suggests the state-of-the-art solution. This solution is based on subordinate control principles involving pulse buck converter topology. The developed simulator provides full-scale ground testing for solar panels and adjacent electrical equipment in various operating modes and may serve as a base for developing a product line of energy efficient power supplies for autonomous objects based on renewables including the PV panels.
