Ítem Game Theory Modeling For Decentralized Peer-To-Peer Solar Energy Market In Colombian Nanogrids(Universidad EAFIT, 2022) Henao Ramírez, Tomás; García Rendón, John JairoAs microgeneration increases, the centralized model of electricity generation will be significantly altered. One of the new models being investigated is the notion of a peer-to-peer electricity market in which prosumers can market their electricity exports to any other household. This new kind of transactive energy market, and community or collective self-consumption, offer new models for trading energy locally. Over the past 10 years, there has been significant growth in the amount of academic literature and trial projects examining how these energy trading models might function. The results show that P2P energy trading provides significant financial and technical benefits to the community and is emerging as an alternative to cost-intensive energy storage systems. This paper investigates a possible game theoretic model for Colombian nanogrids and proposes a new algorithm for automating the sale and purchase of electricity in this market, aiming to optimize the market while providing increased control to householders. It is found that nanogrids may improve financial viability for solar systems at the residential level, concluding that the future for residential solar prosumers is beyond isolated self-consumption.Publicación Impacto de los cambios en el precio del cobre y la tasa de cambio en la rentabilidad de las empresas de instalaciones eléctricas de Colombia(Universidad EAFIT, 2022) Restrepo Aristizábal, Manuela; Isaza Cuervo, Felipe; Corrales Espinosa, AlejandroThis work aims to understand the impact of copper price and exchange rate variations during 2018-2021 period on the profitability of electrical engineering companies (CIIU 4321 in Colombia). For this analysis we used panel data estimation, choosing as measures of profitability the financial indicators of operating margin, gross margin, ROE and ROA as the dependent variable, including the Markup of costs as an independent variable and choosing the size classification according to their incomes level for the unobserved heterogeneity. We conclude that the impact over the cost is controlled for the companies through their expected profit margins, being that an indirect impact on the gross and operating profit and a direct impact on ROE and ROA returnsÍtem Strategic behaviors, pass-through, and the impact of new renewable energy on wholesale cost and retail price in electricity markets : a case study for Colombia(Universidad EAFIT, 2023) Correa Giraldo, Manuel Salvador; García Rendón, John JairoÍtem The role of electricity price and generation from renewable sources in Consumer Index Price- Econometric analysis from Latin American countries(Universidad EAFIT, 2023) Ramos Murillo, Tobías; Fragozo Díaz, Rafael Enrique; Vergara Garavito, Judith Cecilia
