“…This time reserve can further enhance the flexibility of electricity consumption at the residential and commercial levels [2]. According to [5], the use of demand-side flexibility in energy systems will play an important role in the expansion of renewable energy generation, but additional practical assessment is needed. The study proposed in [6], presents an example of how the management of electrical loads can directly support the cost-effective integration of renewable energy into power systems in North America.…”

<p>Demand-side flexibility is defined as the capacity to increase, decrease, or shift a fraction of the electricity consumption in a power system. This type of load management could increase the use of renewable energy sources and the reliability of distributed energy systems. Renewable energy sources, particularly wind and solar energy, are variable in time and usually, the periods of higher generation do not coincide with peak demand periods. This can reduce the share of such renewable energy sources in the energy balance of power systems. This work presents the modeling of a distributed energy system located in Colombia with solar photovoltaic and wind energy installations, as well as lithium-ion batteries. In the model, demand-side flexibility is applied to increase the share of renewable generation in the energy balance of the system, increase the system’s reliability and decrease the cost of electricity for consumers. The model is compared with a system that has no management of electricity consumption to assess the impact of demand-side flexibility on the share of renewables on the energy balance of the system and the system’s reliability.</p>

“…The generated electricity by these plants is expensive and generally leads to pollution and consequent health problems. Hence solar energy system as a replacement of coalbased plant is the better option for reducing the carbon footprints [23].Rising concern of the lack of energy resources and dangerous result of fossil fuel emissions release has started new need of cleaner solar energy source [24], [25], [26]. But one needs to look at the viability of replacing coal-based power plants entirely with renewable energy systems looking at coal's dominance.…”

Solar energy technology has gained significant attention in recent years. It has strongly emerged as an alternative to the conventional mode of electricity generation for developing countries like India for their rising energy needs. Solar energy based electricity generation not only addresses environmental concerns but also increases the energy security and reduces the carbon footprints generated by the coal-based power plant. To boost the share of Renewable energy in the energy mix, the renewable energy policy introduced by the government has acted as a catalyst for large scale deployment of solar energy system to push it as the major energy alternative for India. The normal intensity of solar radiation in India is 220 MW per km square with around 300 sunny days in a year, whereas the coal-based plant generates a huge amount of carbon footprints. Therefore, solar based power generation has the potential of not only reducing the emissions and but also it can cater the rising energy demand. Thus solar photovoltaic plants has become a major alternative energy option in India with the ability to give an improved power supply, reduced global warming and enhance the security of energy supply. In this paper, efforts have been made to look into the overall perspective of solar energy and coal based generation by studying and analyzing the present status, technologies use, accessibility, policies interventions, major contributions, future potentials and trends of solar energy and fossil fuels in the Indian power sector. A feasibility analysis of solar technology implementation with the replacement of coal based plant pant is carried out for Singrauli, India. Results of the proposed study shows that the coal-based power plant generates a huge amount of carbon footprints and it can be reduced by replacing the coal based power plants with solar energy based power generation system. Consequently solar energy based power generation system is a key alternative for developing countries like India having metrological parameters similar to the case study done in this paper with the capacity to provide an improved supply, decreased global warming in addition to improving the energy security.

“…Сложившаяся за последнее десятилетие концепция построения интеллектуальных систем электроснабжения (СЭ), которая в научной литературе получила название Smart Grid, открывает новые возможности по внедрению современных технологий в энергетику с целью ее модернизации [1][2][3]. Ключевым требованием реализации Smart Grid является снижение потерь энергии при ее производстве, передаче, распределении и потреблении.…”

Получены аналитические соотношения, позволяющие рассчитать максимально возможный и реальный коэффициент полезного действия трехфазных трехпроводных систем электроснабжения с двунаправленным потоком энергии. Показано, что даже при высоких значениях КПД в однонаправленных прямом и обратном потоках, общий КПД двунаправленной системы электроснабжения может оказаться незначительным. Корректность полученных соотношений проверена при помощи компьютерной Matlab-модели трехфазной системы электроснабжения с силовым активным фильтром. Ключевые слова: трехфазная система электроснабжения; КПД; мощность резистивного короткого замыкания; коэффициент возврата энергии; двунаправленный поток энергии; полезная мощность
