Wholesale Electricity Market

This paper aims to diagnose the current situation of the Colombian wholesale electricity market in relation to the markets of Argentina, Ecuador, Mexico, Peru and Uruguay. The analysis has been carried out from the point of view of existing supply and demand in the market, of the market participants, of the types of market that have been able to be constituted depending on the regulatory transformations that have taken place, and of the institutional structure on which they are based. This analysis will make it possible to identify whether the Colombian market lags behind the region or whether, on the contrary, it can be considered a benchmark for the other countries in the region.

Advantageous Position

Abstract Legislators who control the congressional agenda have a significant advantage over the membership at large. Policy gatekeepers can restrict change to outcomes they prefer over the status quo and can use this prerogative to keep a legislative party or coalition unified. This article examines agenda-setting rules in 26 Latin American chambers, shows why the institutional structure is theoretically relevant, and reveals some implications for policymaking with evidence from Argentina, Chile, and Mexico. Majority leaders in the Argentine and Chilean lower chambers have successfully blocked passage of legislation opposed by most of their fellow partisans despite the lack of codified gatekeeping rights. Since 1997, none of the major Mexican parties has benefited from the gatekeeping rights established in the rules. Instead, the benefits have come from the parties' advantageous position with respect to the other parties on the steering committee setting the plenary agenda.

Wholesale Electricity Market

Changes in the Mexican electricity market is accompanied by large challenges in the country's economic sector. In the first instance, the need to create a financial market where agents participate of said sector, establishing financing mechanisms and clear rules of action, as well as institutions that safeguard the realization and compliance of operations between them. As in traditional financial markets, market participants will seek to maximize their returns, trying to limit the risks to which they are exposed, related to their operation itself and with the inherent characteristics of the good traded, electricity. The generation of electricity with renewable sources, the correct operation of the electricity market and greater use of electric vehicles, will achieve in Mexico a successful energy transition, where less hydrocarbons are used pollutants to use more clean energy, inheriting future generations a better world.

Resumen: Locura y literatura son dos temas queaparecen intrínsecamente unidos ya sea por esa fronteraliminal que existe entre el genio y la insensatez o quizápor la necesidad de poner en boca de personajes locosuna verdad peligrosa. La figura del loco se ha convertidoen un símbolo, analogía o parábola que significa unmundo en crisis y, en ocasiones, el espejo y catalizadorde la conciencia crítica de la humanidad. En este ensayose analizan dos textos de escritoras latinoamericanasque se acercan al tema de la locura desde la perspectivafemenina. En ambos textos, la locura ocupa un espaciocentral y tiene como objetivo presentar una realidaddesde una óptica diferente. Se establece así unacorrelación entre locura, mirada y literatura, como sila locura fuera el resultado de aprehender realidadesdesde una mirada alternativa para transmitir un mensajeque cuestiona o redefine una realidad. Las novelas sonLa nave de los locos, de la uruguaya Cristina Peri Rossiy Nadie me verá llorar de la mexicana Cristina RiveraGarza. En ambos casos, la figura del loco o de la locuraservirá como eje para transmitir un cuestionamiento yun desafío con respecto a la norma dictada por lasociedad.Palabras clave: locura, razón y sinrazón, mirada/espejo, novela, perspectiva femenina.Madness and Literature: The Other ViewAbstract: Madness and literature are intrinsicallyconjoined topics defined by that blurred line betweengenius and insanity. The figure of the ‘madman’ or theinsane has become staple symbol, analogy and parableto signify a world in crisis, and at times, the mirror andcatalyst of the critical consciousness of humankind. Inthis paper the concepts of madness and literature areexplored in two contemporary Latin American novelsfrom a feminine point of view. In both texts madness is atthe core and both use insanity to expose an alternateview of reality. Thus, a correlation of madness, literatureand gaze is created as if a particular connection betweensight and madness existed, or as if madness were theresult of being able to apprehend realities from analternative perspective. The two novels are La nave delos locos (1984) by Uruguayan Cristina Peri Rossi, andNadie me verá llorar (1999) by Mexican Cristina RiveraGarza. In both cases the topics of mad and madness willquestion and challenge the norms dictated by society.Key words: madness, reason and unreason, gaze/mirror, novel, feminine point of view.

The Military

Abstract Latin American militaries are today in many regards inoperative and obsolete as an instrument of defence. Yet, they seek to maintain their organisational power and privileges. Governments, on the other hand, lack the adequate means to fight criminality, persisting poverty and social inequality. In an apparent win-win situation, Latin American governments have used the military as a wildcard to step in where civilian state capacity falls short, including for urban and border patrols, literacy campaigns and to collect garbage, among many other tasks. The military's manifold internal use has been defended mainly based on pragmatic reasons. We argue instead that the ostensive pareto optimality between militaries and governments has had negative effects for civil-military relations from a democratic governance point of view that takes into consideration the efficiency and effectiveness of how the state delivers basic services across different policy areas.

Tradable Green Certificate

Tradable green certificate (TGC) systems are increasingly used to promote renewable energy generation and mitigate greenhouse gas emissions. In this paper, we investigate the performance of the optimal renewables policy under full separation and full integration scenarios for two countries with TGCs. Our analysis suggests that under full separation, one country’s optimal renewable quota, which maximizes its own welfare, is strategically substitutional for the other country’s in a Cournot Nash equilibrium of the monopolistic market, when cross-border pollution exists. A country tends to become the “leader” in the market by using an information advantage to gain higher welfare. Using geometric illustrations we demonstrate the possibility that a potentially fully integrated electricity market under a TGC system can improve welfare for each country, when compensation between the countries is possible. From a policy point of view, this is significant in support of the demand for a convergence of national renewable policy schemes, where countries cooperate on solving cross-border environmental problems.

This paper proposes a game-theoretic framework for quantifying effects of strategic bidding behavior of load aggregators (LAs) on wholesale electricity market equilibrium. The independent system operator (ISO) employs double-sided auction design to settle transactions in the wholesale electricity market. Generating companies (GENCOs) and LAs submit their bids to the ISO in the economic model of supply function equilibrium. Under the smart grid paradigm, a LA participates in the electricity market on behalf of end-consumers to minimize their total payment for purchasing electricity. In this paper, bi-level programming (BLP) method is employed to determine optimal bidding strategy of self-interested market participants. In the upper level, the profit of intended market participant is maximized and in the lower level, the ISO clears the market via a bid-based security constrained economic dispatch (SCED). Also, competition of GENCOs and LAs is modeled as a non-cooperative game. To examine the effects of strategic bidding behavior of LAs on market equilibrium, the proposed model is applied to the IEEE 9-bus and the IEEE 30-bus test systems. According to numerical results, to allow the LAs to behave strategically along with the GENCOs makes the former better off and the latter worse off, while the net effect of this on total social welfare turns out to be case-contingent.

Wholesale Electricity Market

This paper presents a proposal to estimate prices in the Mexican Wholesale Electric Market, which began operations in February 2016, which is why it moves from a scheme with a single bidder to a competitive market. There are particularities in the case of the Mexican market, the main one being the gradual increase in the number of competitors observed until now and, on the other hand, the geographic and technical characteristics of the electric power generation. The observed prices to date show great fluctuations in the observed data due to diverse aspects; among the stems we can mention the own seasonality of the demand of electrical energy, the availability of fuel, the problems of congestion in the electrical network, as well as other risks such as natural hazards. For the above, it is relevant in a market context to have a price estimation as accurate as possible for the decision-making of supply and demand. This paper proposes a methodology for the generation of electricity price estimation through the application of stable alpha regressions, since the behavior of the electric market has shown the presence of heavy tails in its price distribution.

Fuel cell electric vehicles (FCEVs) have the potential to be used as flexible power plants in future energy systems. To integrate FCEVs through vehicle-to-grid (V2G), agreements are needed between the FCEV owners and the actor that coordinates V2G on behalf of them, usually considered the aggregator. In this paper, we argue that, depending on the purpose of providing V2G and the goal of the system or the aggregator, different types of contracts are needed, not currently considered in the literature. We propose price-based, volume-based, and control-based contracts. Using agent-based modeling and simulation we show how price-based contracts can be applied for selling V2G in the wholesale electricity market and how volume-based contracts can be used for balancing the local energy supply and demand in a microgrid. The models can provide a base to explore strategies in the market and to improve performance in a system highly dependent on V2G.

Summary: My comment is basically restricted to the situation in which less-able students find themselves and refers only to literature in German. From this point of view I am basically able to confirm Marsh's results. It must, however, be said that with less-able pupils the opposite effect can be found: Levels of self-esteem in these pupils are raised, at least temporarily, by separate instruction, academic performance however drops; combined instruction, on the other hand, leads to improved academic performance, while levels of self-esteem drop. Apparently, the positive self-image of less-able pupils who receive separate instruction does not bring about the potential enhancement of academic performance one might expect from high-ability pupils receiving separate instruction. To resolve the dilemma, it is proposed that individual progress in learning be accentuated, and that comparisons with others be dispensed with. This fosters a self-image that can in equal measure be realistic and optimistic.
