The high penetration of distributed renewable resources requires integration strategies that ensure a balance between supply and demand. Transactive energy (TE) comprises a set of mechanisms capable of achieving this objective by using value as an operational parameter. This paper presents a review of the state of the art in TE, aiming to provide the reader with a general overview of concepts and applications. To accomplish this, the document offers a review of market and operational structures, with a particular focus on the role of TE in the composition of local energy markets. Furthermore, an analysis of the value concept in energy is proposed as a linking element between two current topics of academic interest: multi-energy systems and the water-energy-food nexus. Finally, some international and national pilot projects are showcased, allowing for the identification of the practical validity of the concepts described. [ABSTRACT FROM AUTHOR]

Based on China's multilevel engagement strategy in Latin America and the Caribbean, this paper seeks to investigate Argentina's subnational strategies towards the Asian giant in terms of energy transition in two areas: the production of renewable energies and the production of lithium as a storage medium. The perspectives of asymmetric interdependence and structuralism are used to explain the pattern of links between the two countries; and studies of paradiplomacy are used to understand the international actions of Argentina's provinces. The analysis focuses on energy initiatives between 2014 and 2023, using a qualitative methodology with case studies. The initial argument maintains that the development of clean energy is a complementary interest between the Argentine provinces and China, as the Asian country builds its leadership in the field of energy transition, and the provinces diversify their local production matrices.

The proliferation of renewable energy sources and their impact on power systems makes it necessary to conduct studies to ensure the proper operation of the power system. This paper investigates recent research on the impact of renewable energy sources on voltage stability and new methods used to assess this stability. The effects of solar and wind power generation both individually and collectively are studied, along with other inverter models through which renewable energy sources are connected to transmission systems or distribution networks. In addition, the results are highlighted by categorizing them into a deterministic and probabilistic approach. [ABSTRACT FROM AUTHOR]

This document presents in detail the mathematical formulation of the second renewable energy auction in Colombia, used for the allocation of long-term energy contracts, which was carried out through a double-sided auction, defined in Resolutions 4-0590 and 4-0591 of 2019 from the UPME. The mixed integer linear programming model developed in this paper solves an optimization problem that seeks the combination of offers that maximizes the benefit of the consumer, subject to operational and economic constraints proposed by regulatory mechanisms. The effectiveness of the algorithm developed in Python was tested by validating it with real data, obtaining the same results published by UPME. [ABSTRACT FROM AUTHOR]

In recent decades, renewable energies have become increasingly important at the global level, with a significant impact on the sustainable development of various nations. Although multiple papers have examined the efficiency of policies and instruments to promote renewable energy sources, the majority have disregarded the fact that the context in which policies are implemented determines how well they perform. This paper analyzes renewable energy development in the electricity market in Argentina, paying special mind to the contextual conditions in which the policies were designed and finding that in recent history, it is precisely these conditions that constitute the main reason why renewable energies have such a low degree of penetration in the electrical power system in Argentina.

The path to achieve an increased use of renewable energy requires that the technical, political, and economic challenges are addressed in an integrated way. The objective of this paper is to present such socio-technical integration through the analysis of lessons learned in renewable energy in Puerto Rico. The pitfalls in the renewable energy market from technical, social and market acceptance perspectives are presented, as well as the main lessons on needed characteristics: a clear selection process of renewable energy suppliers to ensure socially and technically suitable projects, consistency in administrative decisions to achieve trust among stakeholders, effective inclusion of local communities for social acceptance, and transparency in establishing technical interconnection requirements. Considering the obstacles in the large-scale renewable market in Puerto Rico, distributed energy is presented as viable alternative that can better address social and technical challenges of renewable systems in tropical locations, in particular community microgrids.

After a large-scale blackout power system restoration must be accomplished as soon as possible. For this, the generation must be initially restored, then, the transmission system, and finally the load pick up must be completed. To obtain a faster restoration process, it is necessary to establish start-up methodologies for generating units that first start those units that provide black start, and then take the starting power to other generation units without this characteristic, by means of a feasible transmission route. This paper presents a review of different methodologies of optimal generation start-up for power system restoration reported in the scientific literature taking into account the integration of non-conventional renewable energy sources. Within this review it is highlighted that heuristic methods, despite of being effective, are not used in real-time operation due to their high computational cost. [ABSTRACT FROM AUTHOR]

Photovoltaic generation is considered an environmentally advantageous alternative over conventional energy sources. Although Cuba's energy system is fundamentally based on oil, advances are made in usage of these technologies. This paper objective is to propose an opportunity study of photovoltaic systems connected to grid in COPEXTEL Cienfuegos Territorial Division (DTCC) in order to reduce electricity consumption. PVsyst and RETScreen, design and simulation software for renewable energy systems are used. The profitability for the photovoltaic park in the roof area connected to the grid with internal loads and a total installed nominal power of 150 kW, was determined. The savings for DTCC could be of 2.86 million CUC and about 155 TCO2 are no longer delivered annually, demonstrating economic and environmental benefits. The opportunity to install a photovoltaic park connected to grid to cover the electricity demand is verified. [ABSTRACT FROM AUTHOR]

With the enactment of a new regime regarding the promotion of electrical energy from renewable sources in 2015, Argentina took up the transition towards a more sustainable and diversified energy matrix. Since then, national energy policy has driven the creation of a competitive domestic market for Energy from Renewable Sources (ERS). Meanwhile, industrial policy has focused on promoting the transfer of technology and local industry. This paper analyzes the orientation of these policies, the coherence of their objectives, and the immediate results. Energy policy and industrial policies designed for ERS develop at different speeds and with little coordination, making it necessary for national industry to participate in its value chains.

This paper introduces a methodology for the technical conception of microgrids. It takes into account aspects such as the topological survey of the medium power electrical system, the preselection of renewable sources technologies, the prioritisation of the electrical demand, the localization, dimensioning and operative strategies of the distributed generators, the components model and the microgrid evaluation. This methodology proposes the use of a multi-criteria analysis technique for the prioritisation of the demand and the stability index of (SI) voltage for the location of distributed generators in the microgrid. In this work the computational tool for the power system analysis Neplan® was used for the components modeling and evaluation of the microgrid performance through the IREG voltage regulation index and the optimal power management of the microgrid's generation units.

Optimal operation of energetic installations must considerably influence on its efficiency. By this, the objective of the present paper consists in the definition of the required models structure for the operation of downdraft gasifiers and its identification based on systemic analysis, it identification and the determination of the better adjustment type of model. For the models identification an experimental installation was constructed using, between other biomasses, firewood. Starting from an 3N experimental plan, with three replicas, needed models were identified helped by artificial neural networks and regression techniques. The best results were obtained using neural network, being therefore the most advisable in the preliminary stage of the process of the adaptive construction of operation models of the studied process.

The Cuban sugar industry opens possibilities for biorefinerydevelopment due the characteristics of its mass flow currents and its facilities for obtaining different products, co-products and energy. In present paper, biorefinery schemes were evaluated in a Cuban sugar factory with the integration of products and by-products. Two schemes were proposed for the development of a biorefinery in a Cuban sugar industry, considering the obtaining of second generation ethanol (2G) and third generation biodiesel (3G) (Alternative I), as well as obtaining ethanol from molasse -filters juices and bagasse hydrolyzed and biodiesel 3G (Alternative II). When analyzing these alternatives based on results of mass balances, the AlternativeI is not feasible from a technical point of view, since the amount of bagasse used for hydrolyzateproduction makes the plant not self-sufficient energetically, consuming 2 868 609 kW-h / year of the National Electric System (SEN). When carrying out the economic evaluation it was obtained that alternative IIis technically and economically feasible, since it has a NPV of $ 19 129 956, a TIR of 41.9% and a payback of 4.4 years, achieving in this way the integration of a sugar industry to a biorefinery that obtains second and third generation products.

This paper presents the process of selecting a set of criteria for use in energy planning processes using renewable energy sources in rural areas of Colombia. The implementation of renewable energies in the electrification programs of rural areas in Colombia has several obstacles, among which the inadequate selection of criteria to assess the relevance of projects is highlighted. From a bibliographic review, 33 criteria were identified and submitted to expert judgment with a questionnaire based on the Likert scale. For the selection process, the arithmetic mean and the level of significance were used as reference. After processing the results, 20 subcriteria were selected and grouped into five criteria: technical, economic, social, environmental and risk; which allow a comprehensive evaluation of energy planning projects.

Energy policy, like any other public policy, requires the powers of the government to devise precise and coordinated provisions to efficiently manage a strategic sector. Every country adopts its own energy policy based on factors like resource endowment, macroeconomic policy, the regulatory framework, and its own vision of the relationship between the state and market in a given field, to name a few factors. This paper analyzes energy policy in twenty-first century Argentina, considering its most notable peculiarities, how it has changed and remained the same, and the principal challenges looming ahead.

This paper aims to identify the key determinants of Chilean spot power price and assess their relative importance in recent price decline. To do so, we use a VAR model with weekly data between the years 2015-2016 and variance decomposition analysis to attribute variations of marginal cost to different shocks. The results show that while the availability of water for hydropower and lower fuel prices are important for explaining power spot prices, they only account for 50%-75% of the marginal cost's variance, leaving 25%-50% to other factors, such as more renewable generation and lower generation from oil sources, among other factors.

Given the current environmental problems such as climate change, it is urgent to move towards a new technological and production pattern that allow economic growth and care for the environment to be compatible with each other. Different economic growth models have addressed the relationship between this and technical change, however, they have given little importance to the environment. For this reason, the objective of the current paper is to perform an exploratory and descriptive analysis of the role of technological change as a determinant of economic growth from the Solow (1957) and Kaldor & Mirrlees (1962) models, as well as to raise the need to move towards more sustainable growth models based on a new technological pattern and more efficient forms of production that guarantees a green economy, some principles of Industrial Ecology and the intensive use of renewable energy, sustainability.

The especial characteristics of the Spanish electricity industry hinder the effective competition, in spite of the liberalization process developed. The high concentration in this industry facilitates the possible exercise of market power with the following negative consequences on electricity prices. Likewise, the high energy dependency and the greater participation of renewable energies would have an important impact on prices too. The aim of this paper is to analyze the effects of the liberalization of the Spanish electricity industry on the competition by means of an economic and institutional approach and, by extension, study other factors that have an impact on the household electricity prices.

Wind energy is a renewable system of power generation with great potential to be used and it is a sector with good growth prospects. The development of new wind turbine models assumed that the lifetime of machines is constrained, as the power supplied by the turbine is considered small for the state of wind technology. This involves replacing obsolete turbines to adjust production of wind energy to a growing demand. However, these turbines which are considered obsolete still have good performance for reuse in areas with adequate energy demand. An opportunity to reuse these machines is the isolated rural areas which are typical in northwestern Spain. In this paper is studied the feasibility of obsolete wind turbines to meet the energy needs of isolated rural areas. The methods exposed were used to facilitate the decision making process. We studied the economic feasibility and the results demonstrated that it is a viable investment. [ABSTRACT FROM AUTHOR]

Despite the actions toward a more sustainable development, a poor understanding of the role of architecture and urban design to achieve this goal is appreciated in Cuba. The objective of this paper is to show how it is possible to improve the sustainability in a built environment, by simple and economic transformations, taking as study object the Universidad de Ciencias Informáticas (UCI). A qualitative urban diagnosis was carried out in order to define the main performance strategies. The proposals are progressive, based on minimum intervention and maximum impact. Some of them are: rezoning to reduce distances, using alternative transportation means as bicycles and zero energy minibuses, incorporating new services, using renewable sources of energy and creating an ecological park with a wetland for the gray water treatment. This diagnosis allowed to select the more problematic buildings to be transformed based on a qualitative and quantitative evaluation. [ABSTRACT FROM AUTHOR]
