Analysis of an Independent Double Boost Interleaved Converter in a Renewable Energy Application

In the context of a photovoltaic application, the proposed power electronics conversion stage's operation mode has been considered. The converter is used as an interfacing stage between three PV modules connected in series and the appropriate load. In the second case, an on-premise Real-Time, Rapid Control Prototyping simulation using C2000-69M Texas Instruments DSP with HOTLINK jTAG connectivity to the host computer that runs Altair/Solid Thinking Embed as RCP development environment is established. The resulting current and voltage waveforms for various cases of solar irradiation values were displayed and analyzed.

Optimizing design and dispatch of a renewable energy system with combined heat and power

We add combined heat and power to this set, particularly because we add combined heat and power. Hundreds of thousands of variables and constraints are included in the final mixed-integer linear scheme. We demonstrate how to formulate and solve the corresponding problems, such as the production of near-optimal solutions in minutes, in minutes. For the same situations, a previous iteration of the model needed hours of solution time.

Do renewable energy consumption and green trade openness matter for human well-being? Empirical evidence from European Union countries

However, the effects of green trade openness on human well-being have yet to be investigated. Hence, this research aims to investigate the effects of green trade openness and renewable energy consumption on human well-being in 25 European Union member states over the period from 2003 to 2016. Green trade openness improves human well-being in all quantiles, according to the study, while renewable energy consumption has a significant and positive influence on human well-being in EU nations.

Performance and security enhancement using generalized optimal unified power flow controller under contingency conditions and renewable energy penetrations

In this paper, a novel modular AC transmission system controller called generalized optimal unified power flow controller is introduced to regulate the power flows in multi transmission lines and control the voltages and angles at the load buses. Simultane Simulation Studies were conducted on a standard IEEE 57-bus test platform under single line contingency and investigating various renewable energy source penetrations in New Zealand. The control parameters of GOUPFC are optimized by using whale optimization algorithm, which includes hybridizing WOA and BAT techniques, as well as increasing the voltage profile, and increasing the voltage profile.

N-shaped EKC in sub-Saharan Africa: the three-dimensional effects of governance indices and renewable energy consumption

The study also estimated the direct and indirect effects of the three governance indices on environmental quality in the area by expanding the EKC hypothesis and using three-stage simultaneous equation modeling. Government effectiveness has an indirect negative effect on renewable energy consumption in lower-income SSA countries, where the institutional governance index has a direct negative influence on environmental degradation. Although economic regulation has a direct positive influence, political and institutional policies have a direct negative effect on environmental degradation in the lower-middle-income SSA countries, where economic growth has a tangible positive effect, political and institutional governance have a direct negative effect on environmental degradation. Both income and renewable energy consumption are indicative of indirect negative impact on environmental quality in upper middle-income SSA countries. The inconclusive results of the three governance indices on environmental quality may be due to geographic dissimilarities.

Bi-level optimization based two-stage market clearing model considering guaranteed accommodation of renewable energy generation

The new electricity market mechanisms established to promote renewable energy generation's use are making network participation in market transactions more difficult due to unfair market environment, in which low cost renewable energy production is not included in the high bidding price of high-cost conventional energy generation is not reflected in the high bidding price of high-cost conventional electricity generation. This report explores this topic by recommending a bi-level optimization based two-stage market clearing scheme that considers market players' bidding policies and guarantees the acceptance of renewable energy generation. The first stage introduces a dual-market clearing system that includes a joint market for trading both renewable energy and conventional energy units as well as a subsidy market exclusive to conventional generation units. Following first stage energy allocations, a re-adjustment clearing scheme was then introduced in the second stage to accommodate the power generation of remaining renewable energy units.

Do public subsidies trigger firms’ overinvestment? Evidence from the Korean renewable energy technology industry

Using unbalanced panel data from 61 renewable energy technology companies in Korea between 1991 and 2018, we empirically examine whether government subsidies resulted in firms'u2019 overinvestment. We also find that leverage and free cash balance do not have a direct influence on overinvestment in Korea's renewable energy technology sector directly; however, companies with positive free cash flow tend to overinvest. External growth is the driving factor that has compelled renewable energy technology companies in Korea to overinvest.

Quantification of Wood Biomass in an Area of Sustainable Annual Production in the Brazilian Semiarid Region Aiming at Generating Renewable Energy

The purpose of this research was to quantify the growth and determine the energy potential of forest wood biomass grown from species exploitation in the Caatinga Biome. People with a bole diameter at breast height of at least 2 cm were rejected from Forest inventories.

Impacts of renewable energy on output elasticities and implications for factor shares in European countries: fresh evidence from panel threshold models

The results of labor analysis show the presence of thresholds in the use of renewable energy with nontrivial consequences for the first time; notably, after the thresholds are crossed, the output elasticity of labor rises; however, the production elasticity of labor increases as a result. These changes in the elasticities show significant shifts in factor shares triggered by the specified threshold level of renewable energy consumption. This paper also reports changes in output elasticities of factors of production for other critical parameters, including energy production from oil and gas or coal. These results show a complex and non-linear relationship between energy sources vis-a-vis the economic growth rate, with far-reaching implications for factor shares derived from using renewables vis-u00e0-vis non-renewables. Hence, future economic plans should emphasize the increase of renewable energy in the national energy system in order to maintain the rate of economic growth.

Climate change and 2030 cooling demand in Ahmedabad, India: opportunities for expansion of renewable energy and cool roofs

As climate change-driven temperatures continue to threaten India's population and fuel increased demand for air conditioning, there is a need to determine the local benefits of measures that increase renewable energy production and reduce cooling demand in buildings. Between 2018 and 2030, we investigate the impacts of climate change-driven temperature rises in Ahmedabad's Indian city of Ahmedabad, as well as population and economic growth, on demand for electricity and cool buildings. We estimate the number of energy demand fulfilled by coal-fired power plants versus renewable energy in 2030, as well as the cooling energy demand impacts of increased cool roof adaptation in the city, along with rising cool roof construction. We find that renewable energy capacity could increase from meeting 9% of cooling energy demand in 2018 to 45% in 2030. Cool roofs can be expanded to 20% of total roof area, potentially more than offsetting the city's climate change-driven 2030 rise in cooling demand.
