Con el fin de apoyar de manera sostenible los múltiples sistemas de energía, las estrategiasde mejoramiento de sistemas de eficiencia energética implican la integración y aplicación deherramientas de análisis de energía urbanas. Los sistemas de energía, como la energía solarintermitente, requieren investigación sobre la capacidad de adaptación entre la demanda y laproducción. El análisis de coincidencia de energía requiere de fuentes de error mínimas, con elfin de obtener resultados más puntuales.En ciertas aplicaciones de simulación de energía, el intervalo de tiempo de uso común es deuna hora, sin embargo, estudios han demostrado que esto puede ser una fuente significativade error. Por ende, para la identificación del impacto que tiene la frecuencia temporal en lassimulaciones, se crearon modelos holísticos en alta resolución. Con estos modelos, se pretendela representación y obtención de resultados más precisos y exactos.El modelo de producción de energía fotovoltaica generada in-situ, se basa en un modelodesarrollado por el grupo de investigación Energy Effcient and Smart Cities (EESC). Datospertinentes, tales como la radiación incidente y la radiación global se obtuvieron del softwareMeteonorm. Para la elaboración del modelo de alta resolución de la demanda eléctricadoméstica, el modelo desarrollado por Centre for Renewable Energy Systems Technology ofLoughborough University, fue utilizado y modificado usando información pertinente de CostaRica.Estos modelos, implican módulos fotovoltaicos con producción energética in-situ y representanadecuadamente la demanda de electricidad doméstica. Por lo tanto, el cálculo de los análisisde la capacidad de adaptación de energía pudo ser efectuado. Dichos cálculos involucran losíndices OEF y OEM, que se refieren a la fracción de energía in situ y la coincidencia de energíaen las instalaciones, respectivamente. Mediante estos cálculos, se mostró que el uso de lasresoluciones más gruesas en el análisis de energía conduce a la sobreestimación, y a su vez elporcentaje de error incrementa.

This chapter describes ICT solutions for planning, maintaining and assessing urban energy systems. There is no single urban energy system, but – like the city itself – a system of sub-systems with different scales, spatially ranging from buildings to blocks, districts and to the city, temporally ranging from real time data to hourly, daily, monthly and finally annual totals. ICT support must consider these different sub-systems which makes necessary dividing the chapter into different sections. The chapter starts with framework conditions and general requirements for ICT solutions, and continues discussing urban development simulating models. Then decision support tools are described for energy supply and demand as well as for energy efficiency improvement assessment. Later further instruments for Smart Grid-, district heating- and cooling-planning, as well as demand side management are addressed. In the final section tools are discussed for building automation systems as smallest physical entity within the urban energy system.

Efficiency in the use of energy resources is a priority for the “smart cities” trajectory of sustainable development. This is an essential condition for improving the economic, social and environmental well-being of citizens in general. The importance of life systems orientation to the consumer as an effective user is emphasized. The factors of sustainable development of technologies were identified: updating and modernization of fixed assets in the fuel and energy complex and other sectors of the economy, social and industrial infrastructure on a new technological and energy-efficient basis; provision of forecasting, full accounting and regulation of energy resources consumption, as well as reduction of their losses. The directions of increasing the energy systems efficiency in various sectors are generalized. The necessity of developing human resources through digital skills training was emphasized.

Nowadays, modeling tools are a crucial part of best practice in the elaboration and implementation of a decarbonization plan in any organization, city, or country. The present review analyzes the different modeling tools available to assess energy systems in smart cities. It creates an updated overview of the modeling tools currently available, showing their capabilities and main potential outputs when considering the energy efficiency objective in the context of smart cities in Europe. A restricted set of 14 tools are identified which optimally fulfill the modeling mission of the energy sector, in a smart city context, for different time horizons. The selection considers the capability to include decarbonization assessments, namely, by considering the flexibility to use different external factors, energy policies, technologies, and mainly the implementation of Article 7 from the Energy Efficiency Directive and the “energy efficiency first” principle defined by the European Commission. The ELECTRE TRI method was used to implement a multi-criteria decision approach for sorting modeling tools, aiming at distributing the various alternatives by previously defined categories, and considering the performance criteria of each alternative modeling tool, the analysis suggests that the best options are the LEAP, MESSAGEix, and oemof tools.
