A 100% renewable energy-based stand-alone microgrid system can be developed by robust energy storage systems to stabilize the variable and intermittent renewable energy resources. Hydrogen as an energy carrier and energy storage medium has gained enormous interest globally in recent years. Its use in stand-alone or off-grid microgrids for both the urban and rural communities has commenced recently in some locations. Therefore, this research evaluates the techno-economic feasibility of renewable energy-based systems using hydrogen as energy storage for a stand-alone/off-grid microgrid. Three case scenarios in a microgrid environment were identified and investigated in order to select an optimum solution for a remote community by considering the energy balance and techno-economic optimization. The "HOMER Pro" energy modelling and simulating software was used to compare the energy balance, economics and environmental impact amongst the proposed scenarios. The simulation results showed that the hydrogen-battery hybrid energy storage system is the most cost-effective scenario, though all developed scenarios are technically possible and economically comparable in the long run, while each has different merits and challenges. It has been shown that the proposed hybrid energy systems have significant potentialities in electrifying remote communities with low energy generation costs, as well as a contribution to the reduction of their carbon footprint and to ameliorating the energy crisis to achieve a sustainable future.A modern microgrid is an integrated energy system consisting of localised grouping of distributed electricity generation with storage and multiple electrical loads [11,12]. It can be controlled as one entity or grid, either standalone, completely separate from, or connected to, the existing utility grid [13]. The development of the microgrid has been largely dominated by energy demand-side management, RE penetration and its integration into the utility grid [14,15]. In cases where it is not possible to connect the microgrid to the utility grid for any reason such as the remote or isolated location, a stand-alone microgrid (SAM) is an answer to the power supply challenges [16]. The authors of this research envisioned that the SAM is a good starting point to transit from the classic trend of fossil-fuelled powered systems to 100% RE powered systems.The SAM is a low-voltage power system that supplies a specific localised area [17]. It comprises local power generation systems with load demands, that can operate in islanded mode or off-grid [18,19].In the transition to a 100% RE SAM system, hybrid distributed (decentralized) or centralized energy generation and storage systems are used to meet the energy need [18]. The SAM is presented as a viable and effective solution to the utilisation of renewable energy resources (RER), by minimizing the problems associated with variability and intermittency of the renewables [16]. The main challenge in a SAM system is the optimal sizing of the system components to make the...

ResumenEl presente artículo analiza el modelado de una red de distribución como un mercado energético, pasando de una estructura monopolística a un escenario con un número creciente de competidores. Para lograr este objetivo se evaluó el escenario de una red que hace la transición de la oferta centralizada a distribuida. Se compararon las características del mercado energético, tales como el precio y la cantidad, considerando la generación distribuida y centralizada, y teniendo en cuenta los crecientes niveles de penetración de las energías renovables. Los resultados mostraron que a medida que aumenta el nivel de penetración, el precio de la energía disminuye, aunque muy lentamente debido a la elasticidad precio-demanda de la energía. Finalmente, se concluye que la estructura del mercado de la energía está cambiando debido a las nuevas tecnologías de generación de energía y generación distribuida. Palabras clave: demanda de energía; generación distribuida; mercados energéticos; micro redes The Influence of Penetration Levels of Distributed Generation in the Energy Markets AbstractThe present paper analyzes the modeling of a distribution network as an energy market, moving from a monopolistic structure to a scenario with an increasing number of competitors. To achieve this objective, the scenario of a network considering the transition from centralized to distributed supply was evaluated.Comparison of the characteristics of the energy market, such as price and quantity, considering the distributed and centralized generation was done, also taking into account the increasing levels of penetration of renewable energies. The results showed that as the level of penetration increases, the price of energy decreases, although very slowly, because of the price-demand elasticity of energy. Finally, it is concluded that the structure of the energy market is changing due to the new technologies of generation of energy and distributed generation.

“…At the same time, practical results from OECD countries have shown that technological improvements and optimization of the energy structure and economic structure are crucial to achieving reduction goals [29][30][31]. Based on existing research, we encapsulate the elements of reduction policies into five main factors: energy structure, economic structure, human capital, capital stock, and potential energy efficiency, and consider all reduction policies and measures to be the optimization of one or more factors [32][33][34][35][36].…”

In order to achieve China's target of carbon intensity emissions reduction in 2030, there is a need to identify a scientific pathway and feasible strategies. In this study, we used stochastic frontier analysis method of energy efficiency, incorporating energy structure, economic structure, human capital, capital stock and potential energy efficiency to identify an efficient pathway for achieving emissions reduction target. We set up 96 scenarios including single factor scenarios and multi-factors combination scenarios for the simulation. The effects of each scenario on achieving the carbon intensity reduction target are then evaluated. It is found that: (1) Potential energy efficiency has the greatest contribution to the carbon intensity emissions reduction target; (2) they are unlikely to reach the 2030 carbon intensity reduction target of 60% by only optimizing a single factor; (3) in order to achieve the 2030 target, several aspects have to be adjusted: the fossil fuel ratio must be lower than 80%, and its average growth rate must be decreased by 2.2%; the service sector ratio in GDP must be higher than 58.3%, while the growth rate of non-service sectors must be lowered by 2.4%; and both human capital and capital stock must achieve and maintain a stable growth rate and a 1% increase annually in energy efficiency. Finally, the specific recommendations of this research were discussed, including constantly improved energy efficiency; the upgrading of China's industrial structure must be accelerated; emissions reduction must be done at the root of energy sources; multi-level input mechanisms in overall levels of education and training to cultivate the human capital stock must be established; investment in emerging equipment and accelerate the closure of backward production capacity to accumulate capital stock.Nations Climate Change Conference in 2015, China submitted its Intended Nationally Determined Contribution (INDC) report, in which it states that it will reduce its carbon intensity (CO 2 emissions per unit GDP) by 60-65% in 2030 compared to the level in 2005 [7]. The realization of this target can accelerate China's transformation to a green, low-carbon economy and serve as an important foundation and model in achieving the global target of 2 • C temperature increase [8]. Although some progress has been achieved (i.e., the energy intensity decreased 33.8% from 2005 to 2014), China's carbon intensity is still at a high level. The energy consumption structure still needs to be optimized [9]. In order to achieve its target on emissions reduction in 2030, there is a need for identifying a scientific pathway and feasible strategies, especially before China achieves the early peaking of its carbon emissions [10][11][12].The imbalance in economy development between regions appears in all economies, as differentiated growth always results in early-developing and late-developing regions [13]. The imbalances are visible not only in economic growth, but also in other facets like sectorial structures and models of energ...
