IEEE-PES Abriendo las puertas al almacenamiento de energía: Desafíos para sistema futuros

En esta edición se han recopilado un manual de aplicaciones de almacenamiento de energía. Se incluyen artículos en el diseño de modelos comerciales, análisis normativo, casos de estudio internacionales, evolución de la tecnologías en América Latina y tópicos en los que el almacenamiento podrá recudir costos, mejorar la confiabilidad y permitir la integración de renovables.



Evaluating the Technical and Economic Performance of PV Plus Storage Power Plants

There is growing interest in taking advantage of the declining costs of both PV and energy storage technologies to create combined “PV plus storage” power plants. Yet there has been limited deployment of utility-scale PV plus storage systems, and technical and economic performance metrics for utility-scale PV plus storage systems are not well defined. To help create a common framework for future discussion and analysis, we explore the technical and economic performance of utility-scale PV plus storage systems.



Electricity storage and renewables: Costs and markets to 2030

Electricity storage will play a crucial role in enabling the next phase of the energy transition. Along with boosting solar and wind power generation, it will allow sharp decarbonisation in key segments of the energy market.

As variable renewables grow to substantial levels, electricity systems will require greater flexibility. At very high shares of VRE, electricity will need to be stored over days, weeks
or months. By providing these essential services, electricity storage can drive serious electricity decarbonisation and help transform the whole energy sector.

Future energy systems will rely on a large array of services based on effective, economical electricity storage. This plethora of service needs, with varying performance
requirements, suggests an important role for many different storage technologies.



Perspectives for the energy transition: Investment needs for a low-carbon energy system

The IEA and IRENA separately have examined the investment needs for energy sector pathways that would foster putting the world on track towards a significant reduction in energy-related GHG emissions until the middle of this century. Each institution has developed one core scenario that would be compatible with limiting the rise in global mean temperature to 2°C by 2100 with a probability of 66%, as a way of contributing to the “well below 2°C” target of the Paris Agreement. Both the IEA and IRENA analyses start with the same carbon budget for the energy sector. But the pathways to reaching the goal differ between the two analyses.




Renewables 2017

Analysis and Forecasts to 2O22
