This paper highlights the recenttrends followed by CSIR- Central Glass & Ceramic Research Institute (CGCRI) in establishing Solar Photo-Voltaic Power Plants. This work is aimed at meeting up the conventional energy scarcity at CSIR-CGCRI, SIRSA Campus and developing clean/green energy in order to compensate the global challenges of energy scarcity, climate change and renewable energy development.Abiding by the scheme of Jawaharlal Nehru National Solar Mission (JNNSM) under the aegis ofMinistry of New & Renewable Energy (MNRE), CSIR-CGCRI has implemented Solar Roof-top Grid connected Power Plant at SIRSA Residential staff quarter since February 2014 with the capacity of 37.5KWp (as per agreement). From September 2017, CSIR-CGCRI hasfurther enhanced the capacity to 100.5KWp (as per agreement). Results revealed that there is a stable growth of solar power energy generation. Keeping this in mind, the work pertains to the basic objectives of achieving reduction in carbon food printin line with clean energy generation which leads to reduction in air-pollution and global warmingand at the same time conservation of conventional resources, which is getting reduced day-by-day.Nevertheless, the solar energy generated would eventually lessen the amount of energy purchased from the local Distribution Company (DISCOM) which would benefit our organisation economically.

Renewable Energy Production

This paper is based on a novel approach towards clean energy production, i.e., space innovative applications toward sustainable development. Specifically, the role of Earth observation (EO) satellites in maximizing renewable energy production is considered to show the enormous potential in exploiting sustainable energy generation plants when the Earth is mapped by satellites to provide some peculiar parameters (e.g., solar irradiance, wind speed, precipitation, climate conditions, geothermal data). In this framework, RETScreen clean energy management software can be used for numerical analysis, such as energy generation and efficiency, prices, emission reductions, financial viability and hazard of various types of renewable-energy and energy-efficient technologies (RETs), based on a large database of satellite parameters. This simplifies initial assessments and provides streamlined processes that enable funders, architects, designers, regulators, etc. to make decisions on future clean energy initiatives. After describing the logic of life cycle analysis of RETScreen, two case studies (Mexicali and Toronto) on multiple technologies power plant are analyzed. The different results obtained, when projecting the two scenarios, showed how the software could be useful in the pre-feasibility phase to discriminate the type of installation not efficient for the selected location or not convenient in terms of internal rate of return (IRR) on equity.

The purpose of the study was the comparative analysis of Russian and foreign practices of alternative energy development at the local level. The object of this research is the set of administrative influences that act as determinants of the formation of generation based on renewable energy as part of sustainable development of local communities and green economy. The subject of study is mechanisms, tools and practices of development of alternative energy. The main methods of research work are general theoretical research methods: analysis and synthesis, as well as methods of measurement, comparison, grouping and graphics. To assess the "gaps" between the current and target status of "green" energy as a set of controlled subsystems, the authors propose a method of GAP analysis, at this the main subsystems are allocated as the share of clean energy in the total volume of its generation, the average share of domestic equipment and components in the composition of power plants for alternative energy, the average level of depreciation of power plants to alternative energy, the average time to receive a construction permission for installations of renewable energy sources and connection to the central power grid. The article analyzed and systematized to-date mechanisms to stimulate the development of alternative energy in municipalities and regional governments in foreign countries. General constraints in the development of alternative power generation are revealed. The differentiation of regions of Russia according to the share of "green" power generation in its total production is made. Practices for effective implementation of infrastructure projects of "green" energy in municipalities of the Russian Federation are described and incentives for alternative energy development at the local level are defined. On the basis of generalization of experience of infrastructure projects in the field of alternative energy in cities and regions of Russia the most significant "barriers" in the development of renewable energy infrastructure at the local level are selected and classified , which include economic, administrative, institutional, technological and climatic ones. Several recommendations for the development of incentives to overcome constraints are formulated.

This article examines the current prospects for developing nuclear energy in Ukraine in terms of sustainable development. The strategic importance of nuclear energy for Ukraine is indicated. The advantages of nuclear energy in the context of electricity production's external costs over other energy generation technologies are noted. Today, nuclear energy is considered the most cost-effective low-carbon energy source. An analysis of reports from the Atomic Energy Agency and the US Department of Energy shows that nuclear power generation is a leader in many countries' energy sector, producing cheaper electricity than traditional TPPs. The main challenges for the energy system of Ukraine are highlighted. Among them are: wear and tear and impact on the environment of thermal generation (equipment at thermal power plants is worn out by 70–90 %); the unsatisfactory pace of modernization of the main generating capacities, mainly TPPs; the inconsistency of the flexibility of the United Energy System (UES) of Ukraine with the development of "green" energy (increasing the share of "green" energy increases the risks of UES sustainability) and the corresponding ill-consideredness in the pace and scale of renewable energy implementation. Lack of shunting power; the need to duplicate the capacity of renewable energy due to the low installed capacity factor (ICUF) and significant dependence on natural and climatic conditions; the need to replace existing nuclear power units, which end their extended service life with new, more modern ones that will meet the latest safety and economy standards; the imperfection of the electricity market, primarily in the context of its sale by nuclear generation producers under bilateral agreements; deficit of investments in the whole fuel and energy complex. The main prospects for the development of nuclear energy in Ukraine are identified. Completion of Units 3 and 4 of Khmelnytskyi NPP (KhNPP) remains a critical prospect. An obstacle to this for Ukraine is the lack of appropriate technologies on the Ukrainian side and the curtailment of cooperation with Russia and companies belonging to this state. Another obstacle is that the promising power units of KhNPP based on WWER-1000 belong to the second generation, which today do not morally meet the latest trends and requirements in efficiency and safety standards. Theoretically, Western leaders in the nuclear industry, Orano and Westinghouse, could develop nuclear power plants based on their next-generation "3" and "3+" reactors, where the essential safety requirements are already embedded in the original design of the unit. Another option would be to implement a small modular reactor technology project in Ukraine. Technologically, this will quickly resolve the issue of load management, which arose due to the rapid increase in the share of renewable energy generation in our country. This type of reactor has a significant advantage, which in addition to the minimum load on the environment is: the possibility of placement in areas where additional services are needed in the energy market; low construction costs; frequency of service and operating time; the full cycle of work with fuel. In general, low-power reactors can be used to implement the strategy of hybrid power generation (renewable + nuclear energy).

As reported in the “Clean energy for all Europeans package” set by the EU, a sustainable transition from fossil fuels towards cleaner energy is necessary to improve the quality of life of citizens and the livability in cities. The exploitation of renewable sources, the improvement of energy performance in buildings and the need for cutting-edge national energy and climate plans represent important and urgent topics to be faced in order to implement the sustainability concept in urban areas. In addition, the spread of polygeneration microgrids and the recent development of energy communities enable a massive installation of renewable power plants, high-performance small-size cogeneration units, and electrical storage systems; moreover, properly designed local energy production systems make it possible to optimize the exploitation of green energy sources and reduce both energy supply costs and emissions. In the present paper, a set of key performance indicators is introduced in order to evaluate and compare different energy communities both from a technical and environmental point of view. The proposed methodology was used in order to assess and compare two sites characterized by the presence of sustainable energy infrastructures: the Savona Campus of the University of Genoa in Italy, where a polygeneration microgrid has been in operation since 2014 and new technologies will be installed in the near future, and the SPEED2030 District, an urban area near the Campus where renewable energy power plants (solar and wind), cogeneration units fed by hydrogen and storage systems are planned to be installed.

This paper assesses the relative economic and jobs benefits of retrofitting an 847 MW USA coal power plant with carbon capture, utilization, and storage (CCUS) technology compared to replacing the plant with renewable (RE) energy and battery storage. The research had two major objectives: 1) Estimate the relative environmental, economic, and jobs impacts of CCUS retrofit of the coal plant compared to its replacement by the RE scenario; 2) develop metrics that can be used to compare the jobs impacts of coal fueled power plants to those of renewable energy. The hypotheses tested are: 1) The RE option will reduce CO2 emissions more than the CCUS option. We reject this hypothesis: We found that the CCUS option will reduce CO2 emissions more than the RE option. 2) The RE option will generate greater economic benefits than the CCUS option. We reject this hypothesis: We found that the CCUS option will create greater economic and jobs benefits than the RE option. 3) The RE option will create more jobs per MW than the CCUS option. We reject this hypothesis: We found that the CCUS option will create more jobs per MW more than the RE option. We discuss the implications of these findings.

A nuclear power plant is one of the power sources that shares a large portion of base-load. However, as the proportion of renewable energy increases, nuclear power plants will be required to generate power more flexibly due to the intermittency of the renewable energy sources. This paper reviews a layout thermally integrating the liquid air energy storage system with a nuclear power plant. To evaluate the performance realistically while optimizing the layout, operating nuclear power plant conditions are used. After revisiting the analysis, the optimized performance of the proposed system is predicted to achieve 59.96% of the round-trip efficiency. However, it is further shown that external environmental conditions could deteriorate the performance. For the design of liquid air energy storage-nuclear power plant integrated systems, both the steam properties of the linked plants and external factors should be considered.

In this paper we present a road-map for rural electrification in developing countries by means of Renewable Energy based MiViPPs (Microutility virtual power plants). First and foremost a feasibility and viability analysis of the various upcoming and alternative renewable energy options is performed with respect to rural environmental constraints and demands. Renewable Energy based DDG’s (Decentralized Distributed Generation Units) offer the potential for affordable, clean electricity with minimal losses and effective maintenance and local cost recovery. But Independent DDG projects are fraught with their own issues mainly stemming from the unreliable and intermittent nature of the generated power and high costs. We propose an alternative approach to rural electrification which involves off grid DDG units operated at the local level taking advantage of feasible renewable energy technologies, which can effectively serve rural areas and reduce the urgency of costly grid extension. In MIVIPP model, a multitude of decentralized units (renewable energy based units and a non-renewable energy based unit for last mile backup) are centrally controlled and managed as part of an interconnected network, resulting into a virtual power plant that can be operated as a distributed power plant large enough to reliably serve all the local electricity demands in a cost effective manner. Finally, by a set of simulation results we establish how an automated MIVIPP (based on an Intelligent Auto Control System) effectively addresses all the issues pertaining to Dispersed DDG units by leveraging the scalability achieved by mutually augmenting the supplies from different Renewable Energy Based DDG units.

Renewable Energy Generation

Due to the irreversible energy substitution from fossil fuels to clean energy, the development trend of future power systems is based on renewable energy generation. However, due to the incompatibility of converter-based non-dispatchable renewable energy generation, the stability and reliability of traditional power systems deteriorate as more renewables are introduced. Since conventional power systems are dominated by synchronous machines (SM), it is natural to utilize a virtual synchronous generator (VSG) control strategy that intimates SM characteristics on integrated converters. The VSG algorithm developed in this paper originates from mimicking mathematic models of synchronous machines. Among the different models of implementation, the second-order model is simple, stable, and compatible with the control schemes of current converters in traditional power systems. The VSG control strategy is thoroughly researched and case studied for various converter-interfaced systems that include renewable generation, energy storage, electric vehicles (EV), and other energy demands. VSG-based integration converters can provide grid services such as spinning reserves and inertia emulation to the upper grids of centralized plants, distributed generation networks, and microgrids. Thus, the VSG control strategy has paved a feasible way for an evolutionary transition to a power electronics-based future power grid. By referring to the knowledge of traditional grids, a hierarchical system of operations can be established. Finally, generation and loads can be united in universal compatibility architecture under consolidated synchronous mechanisms.
