“…El uso de los SIG y los MSE plantea retos de integración como la disponibilidad de datos y los recursos computacionales para tratar la información. Así también el enfoque de los SIG permite localizar de manera óptima las energías renovables variables (ERV) basados en condiciones meteorológicas (Martínez-Gordón et al, 2021). En ciertos casos, debido a la carencia de información geográfica, es necesario el diseño de plataformas para recolectar información espacial.…”

El sector residencial es un ejemplo de los retos que se presentan al momento de modelar la heterogeneidad del sistema energético en búsqueda de la evaluación de la política energética. Algunas de las características que influyen en la oferta y demanda de energía del sector residencial son el tipo de consumo, el ingreso de los hogares, la composición familiar, el tipo de vivienda, la zona climática de residencia, entre otras. El objetivo de esta investigación es caracterizar los agentes de consumo energético en el sector residencial del Ecuador. Para lograrlo, en este artículo se presenta una metodología que combina una encuesta nacional (en línea y puerta a puerta) con sistemas de información geográfica (SIG). La encuesta permite definir las principales motivaciones, objetivos de inversión y método de decisión de los agentes al momento de renovar o mantener tecnologías energéticas del hogar. Para esto, se ha clasificado a los agentes con base en su nivel de ingresos. Los SIG permiten localizar espacialmente a los agentes y tener una estimación sobre la población que pertenece a cada agente por el nivel de ingreso. Los resultados se presentan por nivel de ingreso para cada grupo de agentes y se geolocalizan caracterizándolos de forma espacial. Se determina los atributos cuantitativos de cada agente con el fin de ser utilizados en modelación de sistemas de energía.

“…Energinet and Tennet in the North Sea Wind Power Hub 3 ). The NSOG has also been discussed in the political sphere, mainly in the Netherlands, Denmark and Germany 4 There is a large body of literature analysing the implications of the NSOG, for example, in [10] Dedecca et al reviewed NSOG related studies from 2010 to 2016, while in [11] Martinez-Gordón et al included an analysis of NSOG studies up to 2021. These two review efforts identified more than 40 studies evaluating the NSOG from different perspectives.…”

The North Sea Offshore Grid concept has been envisioned as a promising alternative to: 1) ease the integration of offshore wind and onshore energy systems, and 2) increase the cross-border capacity between the North Sea region countries at low cost. In this paper we explore the techno-economic benefits of the North Sea Offshore Grid using two case studies: a power-based offshore grid, where only investments in power assets are allowed (i.e. offshore wind, HVDC/HVAC interconnectors); and a power-and-hydrogen offshore grid, where investments in offshore hydrogen assets are also permitted (i.e. offshore electrolysers, new hydrogen pipelines and retrofitted natural gas pipelines). We compare these scenario results with a business as usual scenario, in which offshore wind is connected radially to the shore and no offshore grid is deployed. All scenarios are run with the IESA-NS model, without any specific technology ban and under open optimization. This paper also presents a novel methodology, combining Geographic Information Systems and Energy System Models, to cluster offshore spatial data and define meaningful offshore regions and offshore hub locations. This novel methodology is applied to the North Sea region to define nine offshore clusters taking into account offshore spatial claims, and identifying suitable areas for single-use and multi-use of space for renewable energy purposes. The scenario results show that the deployment of an offshore grid provides relevant cost savings, ranging from 1% to 4.1% of relative cost decrease (2.3 bn € to 8.7 bn €) in the power-based, and ranging from 2.8% to 7% of relative cost decrease (6 bn € to 14.9 bn €) in the power-and-hydrogen based. In the most extreme scenario (H2) an offshore grid permits to integrate 283 GW of HVDC connected offshore wind and 196 GW of HVDC meshed interconnectors. Even in the most conservative scenario (P1) the offshore grid integrates 59 GW of HVDC connected offshore wind capacity and 92 GW of HVDC meshed interconnectors. When allowed, the deployment of offshore electrolysis is considerable, ranging from 61 GW to 96 GW, with capacity factors of around 30%. Finally, we also find that, when imported hydrogen is available at 2 €/kg (including production and transport costs), large investments in an offshore grid are not optimal anymore. In contrast, at import costs over 4 €/kg imported hydrogen is not competitive.

The energy transition requires integration of different energy carriers, including electricity, heat, and transport sectors. Energy modeling methods and tools are essential to provide a clear insight into the energy transition. However, the methodologies often overlook the details of small-scale energy systems. The study states an innovative approach to facilitate sub-national energy systems with 100% renewable penetration and sectoral integration. An optimization model, OSeEM-SN, is developed under the Oemof framework. The model is validated using the case study of Schleswig-Holstein. The study assumes three scenarios representing 25%, 50%, and 100% of the total available biomass potentials. OSeEM-SN reaches feasible solutions without additional offshore wind investment, indicating that they can be reserved for supplying other states’ energy demand. The annual investment cost varies between 1.02 bn – 1.44 bn €/yr for the three scenarios. The electricity generation decreases by 17%, indicating that with high biomass-based combined heat and power plants, the curtailment from other renewable plants can be decreased. Ground source heat pumps dominate the heat mix; however, their installation decreases by 28% as the biomass penetrates fully into the energy mix. The validation confirms OSeEM-SN as a beneficial tool to examine different scenarios for sub-national energy systems.
