The goal of this paper is to introduce the market modeling tool Antares and to point out possibilities of its utilisation in cost-benefit analysis of energy projects. Market modeling of power systems represents a detailed modeling of generating units, consumption and cross-border connections with neighboring systems in order to find economically optimal dispatching of power plants by which the total consumption will be satisfied. In this paper, two power systems connected by cross-border transmission lines will be modeled (in one of them there is a large amount of installed capacity of renewable energy sources). The benefits of reinforcing cross-border connection embodied in avoiding curtailment of available renewable energy due to low energy consumption and lack of energy storage systems will be analyzed, along with corresponding benefits of reduced CO2 emissions due to the ability to transfer green energy into neighboring power systems through increased cross-border capacity.

Insight Into

Oil drives the entire world economy, and it is entirely a geostrategy issue. The strong development of the economy over the past few decades has provided a global stage for those countries that have a stable political establishment while managing enormous amounts of oil. Now, year after year, it is becoming increasingly clear that the importance of oil and gas is falling away, and it is those energy sources that bring about a reduction in the half-life that comes into the scene. Oil and gas are non-renewable energy sources and as such are naturally limited, therefore their reserve will become economically unprofitable in the future, and exploitation will reach its natural end. The aim of this research paper is divided into two structures: the first thesis concerns giving a fresh insight into the state of the oil market from the beginning of the pandemic to the present day. The issue of geopolitical relations between Riyadh and Moscow is to be addressed here and how much of a negative consequence the price war has left on their fiscal calculations, although geopolitical friction has deepened the shock further into financial markets. Thus, the fiscal calculation of both countries suffered revenue shocks, but it also prompted an even deeper decline in stock indexes and temporary stagflation of the global economy. The second thesis refers to a brief review of the analysis of the long-term future of non-renewable and renewable energy sources. The future of cleaner forms of energy is imperative, but also a challenging task, as this means shifting the entire structure of national economies to green and renewable. The focus is on giving insight into why this is a necessity, but also why there could be a dangerous precedent and negative cash flows in some structures of the economy. Currently, and any future planning and fulfillment of climate guidelines, must not lead to an increase in energy poverty and consequently a decrease in living standards, because in all geopolitical games the line is always drawn between rich and poor countries, that is, advanced economies and developing economies. Therefore, the long-term and global leaders in green and renewable energy sources will be those countries that successfully implement public interests in these projects, because only in this way can the goal be met – shifting a certain structure of the economy to cleaner sources while satisfying social utility and increasing employment.

Synchronous Generators

The main purpose of developing microgrids (MGs) is to facilitate the integration of renewable energy sources (RESs) into the power grid. RESs are normally connected to the grid via power electronic inverters. As various types of RESs are increasingly being connected to the electrical power grid, power systems of the near future will have more inverter-based generators (IBGs) instead of synchronous machines. Since IBGs have significant differences in their characteristics compared to synchronous generators (SGs), particularly concerning their inertia and capability to provide reactive power, their impacts on the system dynamics are different compared to SGs. In particular, system stability analysis will require new approaches. As such, research is currently being conducted on the stability of power systems with the inclusion of IBGs. This review article is intended to be a preface to the Special Issue on Voltage Stability of Microgrids in Power Systems. It presents a comprehensive review of the literature on voltage stability of power systems with a relatively high percentage of IBGs in the generation mix of the system. As the research is developing rapidly in this field, it is understood that by the time that this article is published, and further in the future, there will be many more new developments in this area. Certainly, other articles in this special issue will highlight some other important aspects of the voltage stability of microgrids.

Lighting Retrofit

The use of formal methods and artificial intelligence has made it possible to automatically design outdoor lighting. Quick design for large cities, in a matter of hours instead of weeks, and analysis of various optimization criteria enables to save energy and tune profit stream from lighting retrofit. Since outdoor lighting is of a large scale, having luminaires on every street in urban areas, and since it needs to be retrofitted every 10 to 15 years, choosing proper parameters and light sources leads to significant energy savings. This paper presents the concept and calculations of Levelized Cost of Electricity for outdoor lighting retrofit. It is understood as cost of energy savings, it is in the range from 23.06 to 54.64 EUR/MWh, based on real-world cases. This makes street and road lighting modernization process the best green “energy source” if compared with the 2018 Fraunhofer Institute cost of electricity renewable energy technologies ranking. This indicates that investment in lighting retrofit is more economically and ecologically viable than investment in new renewable energy sources.

The Future

The goal of power sector in Nigeria is to efficiently and reliably transmit electrical power to all parts of the country which are made up of thirty-six states of the federation and the federal capital territory. The constituents of electrical power system are the generation, transmission, distribution and the utilization of electrical energy. There is gross power imbalance between the generation and the required power demand which has culminated into a defective economy in the last three decades. This paper therefore examines the power imbalance between the generation and power demand by the consumers and therefore stresses the need to harness the opportunity of renewable energy generation close to the gap between the power generation and power demand. This will help in transmitting and distributing efficient, effective, reliable power to consumers and improve both human and capital development. The availability of renewable energy sources such as sun, wind and small hydro power will be explored for the future of power generation in the country to fill in the gap between power generation and demand in Nigeria

Load Variations

The frequency of power systems is very sensitive to load variations. Additionally, with the increased penetration of renewable energy sources in electrical grids, stabilizing the system frequency becomes more challenging. Therefore, Load Frequency Control (LFC) is used to keep the frequency within its acceptable limits. In this paper, an adaptive controller is proposed to enhance the system performance under load variations. Moreover, the proposed controller overcomes the disturbances resulting from the natural operation of the renewable energy sources such as Wave Energy Conversion System (WECS) and Photovoltaic (PV) system. The superiority of the proposed controller compared to the classical LFC schemes is that it has auto tuned parameters. The validation of the proposed controller is carried out through four case studies. The first case study is dedicated to a two-area LFC system under load variations. The WECS is considered as a disturbance for the second case study. Moreover, to demonstrate the superiority of the proposed controller, the dynamic performance is compared with previous work based on an optimized controller in the third case study. Finally in the fourth case study, a sensitivity analysis is carried out through parameters variations in the nonlinear PV-thermal hybrid system. The novel application of the adaptive controller into the LFC leads to enhance the system performance under disturbance of different sources of renewable energy. Moreover, a robustness test is presented to validate the reliability of the proposed controller.
