“…We found scant literature in this line. Primarily, public supports are tested with energy utility transmission (Heideier et al , 2020), energy policy optimization (Safarzadeh et al , 2020), energy efficiency initiatives (Lim and Brown, 2018), techno-economic perspectives of societies (Bukarica and Tomšić, 2017). We use following equation to estimate the connection between public supports and energy efficiency financing during the COVID-19 pandemic, where, i indicates the country (= 1,… i N ) and t indicates the time period (= 1 …) t .where Yit indicates the public supports from i countries at t time, with a vector notation factor highlighting CGM function effects, that are key proxy measures of energy efficiency financing along with β and ϑit central limits.…”

PurposeThe study aims to empirically estimate the role of public supports for energy efficiency financing and presents the way forward to mitigate the energy financing barriers that incurred during the COVID-19 crisis.Design/methodology/approachUsing the G7 countries data, the study estimated the nexus between the constructs. Generalized method of moments (GMM) and conventional increasing-smoothing asymptotic of GMM are applied to justify the study findings. Wald econometric technique is also used to robust the results.FindingsThe study findings reported a consistent role of public support on energy efficiency financing indicators, during the COVID-19 crisis period. G7 countries raised funds around 17% through public supports for energy efficiency financing, and it raised 4% of per unit energy usage to GDP, accelerated 16% energy efficiency and 24% output of renewable energy sources, during COVID-19. By this, study findings warrant a maximum support from public offices, energy ministries and other allied departments for energy efficiency optimization.Practical implicationsThe study presents multiple policy implications to enhance energy efficiency through different alternative sources, such as, on-bill financing, direct energy efficiency grant, guaranteed financial contracts for energy efficiency and energy efficiency credit lines. If suggested policy recommendations are applied effectively, this holds the potential to diminish the influence of the COVID-19 crisis and can probably uplift the energy efficiency financing during structural crisis.Originality/valueThe originality of the recent study exists in a novel framework of study topicality. Despite growing literature, the empirical discussion in the field of energy efficiency financing and COVID-19 is still shattered and less studied, which is contributed by this study.

“…A meta é ousada considerando que a necessidade de aumento da produção de energia é reconhecida como um dos fatores mais relevantes na aceleração das mudanças climáticas e no agravamento do aquecimento global (GARLET et al, 2019). O tema há muito vem sendo discutido em nível internacional e, atualmente, pode-se considerar que há consenso no que diz respeito à urgência em se reduzir a emissão de gases do efeito estufa (HEIDEIER et al, 2020), potencializadores destes fenômenos. Neste sentido, considerando que o processo de geração de energia por meio da queima de combustíveis fósseis representa aproximadamente 80% do fornecimento de energia primária global (JOHANSSON; THOLLANDER, 2018), constata-se que esta figura como um dos principais causadores deste tipo de emissão (IPCC, 2014), além das limitações econômicas e comerciais inerentes à exploração deste recurso (CARPIO, 2021).…”

A energia é um recurso fundamental para a manutenção da vida humana e para o contínuo desenvolvimento de uma sociedade moderna, uma vez que praticamente todas as atividades atuais requerem sua ampla utilização. Considerando a tendência atual de expansão da demanda por eletricidade, há uma crescente procura por tecnologias renováveis. Neste contexto, o objetivo deste trabalho é a análise da evolução da geração distribuída de energia fotovoltaica nas cidades das Regiões dos Lagos e Norte Fluminense. O objetivo proposto foi atingido por meio da prospecção de informações junto à Agência Nacional de Energia Elétrica e do Instituto Brasileiro de Geografia e Estatística, as quais em uma primeira etapa foram compiladas, classificadas e agrupadas em tabelas e planilhas de forma a facilitar sua visualização e compreensão. Após a análise crítica dos dados, conclui-se que todas as cidades analisadas encontram-se em franco processo de expansão desta tecnologia, havendo uma predominância das classes de consumo residencial e comercial. Além disso, não foi identificada relação direta entre o PIB per capita dos municípios e sua capacidade instalada, porém, esta hipótese não deve ser totalmente descartada, considerando-se o crescimento exponencial apresentado pela cidade de Maricá nos últimos dois anos. Com este estudo, espera-se apresentar informações atualizadas, permitindo aos tomadores de decisão locais a implantação de projetos e legislações mais assertivas sobre o tema que, inclusive, integra um dos dezessete Objetivos de Desenvolvimento Sustentável da Organização das Nações Unidas.

“…Those limitations are mainly due to maintaining the stability and maintaining the voltage range of the power system at its permissible level [3,4]. Distributed Generations (DGs) are one of the best solutions to prevent congestion in the transmission lines [5]. DGs have several advantages, such as reducing energy costs, improving power quality and reliability, and preventing environmental pollutions.…”

Optimal Power Flow Incorporating FACTS Devices and Stochastic Wind Power Generation Using Krill Herd Algorithm

et al. 2020

View full text Add to dashboard Cite

This paper deals with investigating the Optimal Power Flow (OPF) solution of power systems considering Flexible AC Transmission Systems (FACTS) devices and wind power generation under uncertainty. The Krill Herd Algorithm (KHA), as a new meta-heuristic approach, is employed to cope with the OPF problem of power systems, incorporating FACTS devices and stochastic wind power generation. The wind power uncertainty is included in the optimization problem using Weibull probability density function modeling to determine the optimal values of decision variables. Various objective functions, including minimization of fuel cost, active power losses across transmission lines, emission, and Combined Economic and Environmental Costs (CEEC), are separately formulated to solve the OPF considering FACTS devices and stochastic wind power generation. The effectiveness of the KHA approach is investigated on modified IEEE-30 bus and IEEE-57 bus test systems and compared with other conventional methods available in the literature.
