“…Unlike conventional fossil fuel power plants, renewable energy power plants are not "disposable" or "generative" (so called because they depend on variable resources such as solar and wind, which change over the course of a day). On a centralized supply scale, a renewable power plant is comparable to a fossil fuel power plant producing several hundred megawatts of electricity [179]. Wind, geothermal, solar, water, and other renewable technologies are the most popular energy sources in the world today.…”

The electrical power sector plays an important role in the economic growth and development of every country around the world. Total global demand for electric energy is growing both in developed and developing economies. The commitment to the decarbonization of economies, which would mean replacing fossil fuels with renewable energy sources (RES) as well as the electrification of transport and heating as a means to tackle global warming and dangerous climate change, would lead to a surge in electricity consumption worldwide. Hence, it appears reasonable that the electric power sector should embed the principles of sustainable development into its functioning and operation. In addition, events such as the recent European gas crisis that have emerged as a result of the massive deployment of renewables need to be studied and prevented. This review aims at assessing the role of the renewable energy in the sustainable development of the electrical power sector, focusing on the energy providers and consumers represented both by businesses and households that are gradually becoming prosumers on the market of electric energy. Furthermore, it also focuses on the impact of renewables on the utility side and their benefits for the grid. In addition, it identifies the major factors of the sustainable development of the electrical power sector.

“…The review looked at sources of flexibility in a power system and impact of intermittent renewable energy sources, and available metrics for quantifying flexibility. Power system flexibility metrics were also reviewed in detail in the review paper produced by Emmanuel et al [22]. The metrics for power system flexibility adequacy include available generation or demand response capacity in MW required to respond to a ramp event, and rate of response of generation output or load curtailment in MW/minute [22].…”

Entrance of intermittent renewable power energy sources has brought in benefits mainly associated with emission reduction to help the climate change cause and reduce pollution. However, entrance of renewable generation sources, mainly wind and solar generation that are intermittent energy sources by nature has not come without its own challenges. Future power grids will see continued elevation of intermittent generation with instantaneous penetration levels that may potentially be as high as 100% for some periods. This paper reviews published works and highlights technical challenges that require further research to ensure that power grids that will be dominated by inverter-based generation or purely powered by inverter-based generation continue to operate reliably and remain stable for all operating scenarios. The paper outlines further research opportunities in areas of power sytem security assessment, voltage and frequency management, power system stability, resource forecasting techniques for unit commitment, behind the meter generators and loads integration to grid, frequency and voltage support, power system flexibility assessment methods, protection schemes enhancement, power quality mitigation techniques and modelling requirements to support real-time power system operation.

“…This is why the power plant must be able to provide energy consistently to meet the load requirements at all times. The electric power system can be described in simple terms as a simple relationship between the generating unit and the energy users, which is currently evolving into a large grid electric power system with many interconnected physical parts [1,2]. This system has evolved rapidly with the advancement of electrical technology, incorporating various connections at various voltage levels into an integrated system.…”

The electricity system is generally rapidly developing for covering various power demands with requiring a reliable and safe supply where the substructures are expanding further in generation systems, transmission systems, and distribution systems. However, the system must be run economically to access energy at a cost-effective level related to existing energy enterprises and energy consumption in the load which is represented periodically in the total costs of operations for all operating units. As a basis for its determination, the transmission of economic power within the technical limits applicable is taken into consideration. Environmental factors, on the other hand, are also an impediment to technical limitations. As a result, the operation's economic measure is expressed in the process of providing and selling energy to customers. These works use the Artificial Bees Colony algorithm to determine the scheduling of generating units using the basic principle of optimization to describe its relationship as an economic function. The IEEE-30 bus system is used as a basic model for system development. The analysis' findings show that the weighting factor scheme has an impact on the minimum total cost and that the combination of the electricity distribution process and environmental factors has implications for the operational financial condition and electricity production. The power output, in particular, is proportional to the cost of each generating unit.
