Balanced Development

The need to enhance energy access has led to the growing recognition of renewable energy sources in sustainable regional development. However, solar power, one of the less polluting renewable energy sources, continues to receive little attention in some developing countries seeking balanced development. Through a review of the literature, this paper examines the need for regional electrification by solar power and suggests measures to integrate regional energy policies and processes for balanced development. The authors find that there are many social, economic, and environmental benefits associated with using solar power. For instance, solar energy creates employment opportunities, reduces a country’s foreign dependence, improves freedom of choice, improves a country’s gross domestic product (GDP) and human development index (HDI), and is associated with improved environmental conservation. The region of East Africa is keen to reap these sustainable development gains through solar power electrification. The establishment of the East African Centre for Renewable Energy and Energy Efficiency constitutes an important melting pot for diverse renewable energy policies, in addition to confirming a commitment to solar power deployment. Moreover, some East African Community (EAC) states appear to be progressing faster towards regional solar power projects, while other states are lagging due to complex contextual challenges. However, the overall contribution of solar power to sustainable development remains low, as individual states appear to be focused on developing their national solar power projects. Nonetheless, there is great hope for regional development through shared solar power development if EAC states implement a number of regulatory and voluntary interventions.

AbstractSudan is an agricultural country with fertile soil and ample water resources, as well as livestock and forestry resources, and agricultural residues. Energy is one of the key factors in the development of Sudan's national economy. We present an overview of the energy situation in Sudan, with reference to its end uses and its regional distribution. We separate energy sources into two main types: conventional energy (biomass, petroleum products, and electricity) and non-conventional energy (solar power, wind energy, hydro-electric, etc.). Sudan has a relatively high abundance of sunshine and solar radiation, and has moderate biomass, hydro-electric and wind energy resources. Exploiting the available new and renewable energy sources to provide part of the local energy demand, as alternatives to conventional fossil energy, has become a major issue in Sudan's strategic planning of future energy policies. Sudan presents an important case study with respect to renewable energy, as it has a long history of meeting its energy needs by use of renewable sources; Sudan's portfolio is broad and diverse, due in part to the country's wide range of climates and landscapes. Like many African frontrunners in the utilisation of renewable energy, Sudan has a well-defined commitment to continue research, development, and implementation of new technologies. Sustainable low-carbon energy scenarios in the new century emphasize the importance of exploiting the untapped potential of renewable resources. Sudan's rural areas in particular, can benefit from this transition. The increased availability of reliable and efficient energy services will stimulate the development of new alternatives. We conclude that using renewable, environmentally friendly energy must be encouraged, promoted, implemented, and demonstrated by full-scale energy plants or collection devices, in particular for use in remote rural areas.

Wind Potential

In parallel with the rapid increase in energy consumption today, it is known that conventional energy resources will be exhausted in the near future. Renewable energy sources are becoming more important today with decreasing available fossil resources and increasing energy needs. Wind energy is a clean and renewable energy source and has a remarkable importance. Wind energy is one of the most important renewable energy sources, whose technology and use have developed rapidly and their economy has become competitive with fossil energy sources. The systems that convert the energy in the wind into electrical energy are wind turbines. Wind turbines are classified according to their rotational axes, revolutions, powers, number of wings, wind effect, gear characteristics and installation locations. Energy has become one of the most important problems of the world countries today. Energy demand, as in many countries, is increasing with each passing day in Turkey. For this reason, solutions are sought to provide the energy needed in a timely, sufficient and reliable manner. The energy needed in these solution suggestions should be provided from domestic production opportunities and local energy sources as much as possible. In this study, usability of wind energy is tried to be revealed in Osmaniye province and its surroundings. When the wind map studies in Turkey are examined, in Osmaniye Province it has been found that the presence of wind potential, it is necessary to increase the number of WPP to benefit more from the potential of wind energy.

Power Quality Improvement

Due to the rapid increase in energy demand with depleting conventional sources, the world’s interest is moving towards renewable energy sources. Microgrid provides easy and reliable integration of distributed generation (DG) units based on renewable energy sources to the grid. The DG’s are usually integrated to microgrid through inverters. For a reliable operation of microgrid, it must have to operate in grid connected as well as isolated mode. Due to sudden mode change, performance of the DG inverter system will be compromised. Design and simulation of an optimized microgrid model in MATLAB/Simulink is presented in this work. The goal of the designed model is to integrate the inverter-interfaced DG’s to the microgrid in an efficient manner. The IEEE 13 bus test feeder has been converted to a microgrid by integration of DG’s including diesel engine generator, photovoltaic (PV) block and battery. The main feature of the designed MG model is its optimization in both operated modes to ensure the high reliability. For reliable interconnection of designed MG model to the power grid, a control scheme for DG inverter system based on PI controllers and DQ-PLL (phase-locked loop) has been designed. This designed scheme provides constant voltage in isolated mode and constant currents in grid connected mode. For power quality improvement, the regulation of harmonic current insertion has been performed using LCL filter. The performance of the designed MG model has been evaluated from the simulation results in MATLAB/ Simulink.

The Impact

Abstract Increasing the share of renewable energy sources is one of the core policies of the European Union. This is because of the fact that this energy is essential in reducing the greenhouse gas emissions and securing energy supplies. Currently, the share of wind energy from all renewable energy sources is relatively low. The choice of location for a certain wind farm installation strongly depends on the wind potential. Therefore the accurate assessment of wind potential is extremely important. In the present paper an analysis is made on the impact of significant possible parameters on the determination of wind energy potential for relatively large areas. In the analysis the type of measurements (short- and long-term on-site measurements), the type of instrumentation and the terrain roughness factor are considered. The study on the impact of turbulence on the wind flow distribution over complex terrain is presented, and it is based on the real on-site data collected by the meteorological tall towers installed in the northern part of Bulgaria. By means of CFD based software a wind map is developed for relatively large areas. Different turbulent models in numerical calculations were tested and recommendations for the usage of the specific models in flows modeling over complex terrains are presented. The role of each parameter in wind map development is made. Different approaches for determination of wind energy potential based on the preliminary developed wind map are presented.

The Impact

The overall purpose of this study is to evaluate the impact of financing renewable energy sources on the assessment of sustainable development in Poland’s provinces. There are also two detailed objectives: (1) define how Polish policies are being passed on to local authorities; (2) realize a Poland’s provinces ranking, taking into account the indicators of sustainable development, thanks to the taxonomic measure of development in the area of environmental order. This study deals with the taxonomic assessment of local sustainable development in the local administration units of Poland. To this end, the methods of linear ordering were applied for the assessment of the level of objects differentiation with the use of a closed set of statistical features. The presented analysis proved that the taxonomic distances between synthetic measures for particular provinces are considerable. The highest values of the integrated measure in 2018 were obtained by the following provinces: Podlaskie, Subcarpathian and Lubusz. It is noteworthy to point to the big changes in the ranking between 2018 and 2016. The cluster analysis showed some progress in achieving the goals of sustainable development. The group of provinces with an average level of sustainable development in 2018 included six provinces compared to two provinces in 2016. Removing one indicator from the integrated measure (the financing of renewable energy sources (RES)) led to a moderate increase in the integrated measure across all the provinces. This implies that, on average, the financing of renewable energy sources exerts increasingly smaller impacts on the level of sustainable development in Poland.
