IEA PVPS Task 14: Solar PV in the 100% Renewable Energy Source based Power System (working period 2018 - 2022)
IEA PVPS Task 14 aims to enhance the international collaborative efforts defining the technical base for photovoltaic solar energy as a cornerstone in the future 100% renewable energy source based electric power system.
By participating in the IEA Wind Task 27, a number of goals could be achieved, including the development of a site assessment scheme for wind turbines in areas with high turbulence intensities, the further development of the IEC 61400 standard, the participation in the “Compendium of IEA Wind TCP Task 27 case studies “And the update of the “Small Wind Power Report 2018” as well as activities such as holding the event “Small Wind Power Conference” in Austria.
The international Smart Grid Action Network (ISGAN) aims to improve the understanding of Smart-Grid-technologies and to accelerate global deployment. The work in ISGAN is structured in eight standing working groups (annexes). The present project describes the Austrian contribution to Annex 1: Smart Grids Inventory and Annex 2: Smart Grids Case Studies.
ISGAN Annex 7 deals primarily with institutional and socio-technical issues in connection with the transition of the energy system, with smart grids at its core. It thus aims to bundle international experience and interdisciplinary research activities on smart grids, to process them and to make them usable for policy makers and stakeholders.
The IEA-PVPS Task 14, led by Austria as Operating Agent, promotes the use of grid connected PV as an important source in electric power systems on a high penetration level where additional efforts may be necessary to integrate the dispersed generators in an optimum manner. In a number of case studies from the participating countries, the challenges and approaches in the field of distribution networks, system management and power electronics components were shown in an international context. The result being elaborate reports with targeted recommendations and required measures to significantly increase the share of photovoltaics in electricity grids.
As part of the "Annex 63" project, Austria has worked with 10 other countries to develop guidelines for the successful implementation of energy strategies at local level. The results include support for nine strategic measures, descriptions of case studies, support materials and recommendations for different target groups.
Together with experts from 11 countries, the EI-JKU has analysed cost-benefit models and developed proposals for their adaptation and further development. In the course of the work, the EI-JKU dealt in particular with two questions: how such an evaluation model can be adapted to Austrian conditions and which socio-economic factors influence the question of whether an end consumer emerges as a winner or loser from Smart Grid-based functionalities.
The aim of Annex 42 is to analyse the technical possibilities as well as the economic/regulatory framework conditions of heat pumps for load balancing in smart grids, which are largely controlled by electricity supplier, and to investigate the impact on thermal consumers and possible potentials, in order to work out economic incentive models for load shifting and the benefits for energy supply companies and end customers on this basis.
IEA SHC Task 52 focused on the analysis of the future role of solar thermal heat in integrated urban energy systems. The potential of solar thermal applications to cover the low-temperature heat demand in future low-carbon energy systems was investigated against the background of the rapidly changing framework conditions in the energy sector. Best practice examples for the integration of solar thermal systems into urban energy systems were evaluated and documented.
IEA EBC Annex 64: Optimised Performance of Energy Supply Systems with Exergy Principles (Working period 2014-2018)
To reduce CO2 emissions in cities, an overall understanding of energy conversion processes is necessary, which also takes temperature levels into account. This is particularly important when alternative heat sources such as waste heat, ambient heat, solar and geothermal energy are to be used, as these often have a low temperature level, i.e. a low exergy content. Accordingly, urban energy systems are analysed and optimised within the framework of the IEA EBC Annex 64 with the help of the exergy approach.
The goal of the Annex Electric Motor Systems is to raise awareness on the large savings potential in motor systems, while showing the realization method of such a path. Currently, Austria leads the task Energy Audits for Motor Systems to develop recommendations for carrying out energy audits for motor systems based on international standards.
The focus of IEA SHC Task 51 ‚Solar Energy in Urban Planning’ has been placed on the topic of solar energy integration in urban environment. Hereby, different international examples, options and processes for planning and implementation of solar energy measures in cities throughout the world have been screened, outlined and equipped with recommendations for further development. The core outcomes of the project address different options and possibilities for optimization of planning processes, framework conditions, tools, methods and education aiming to attain more effective and timely understanding as well as integration of solar energy in urban context.
This task aims at the identification and development of effective business models for energy services, which lead to a sustainable growth of energy efficiency services. Therefore the various national framework conditions and contexts have been analysed, that are necessary for a successful development of such business models. Examples for start-ups and entrepreneurs have been discussed, their challenges and deficits as well as success factors in terms of capabilities/skills identified and out of these findings a web based analysis tool been developed.
Target of IEA EBC Annex 61 was the development of technical and economical concepts for Deep Energy Retrofit of public buildings. To force high-quality and energy efficient retrofit, besides the enhancement and dissemination of innovative, technical retrofit concepts, the focus was in the development of innovative business models (energy-contracting).
IEA DSM Task 24: Behaviour Change in DSM – Helping the Behaviour Changers (Working period 2015-2017)
More than 20% of the use of energy for small consumers can be saved by changed behaviours. Past efforts to tap these potentials through DSM-interventions are not effective. The Task 24 dealt with the most important actors groups as well as tools, which support the behaviour changers in their daily work. In addition, an assessment method for DSM-interventions in the frame of the Austrian law on energy efficiency was elaborated.
IEA EBC Annex 60: New generation computational tools for building and community energy systems based on the Modelica and Functional Mockup Interface standards
The objective was to develop and demonstrate next-generation computational tools that allow building and community energy grids to be designed and operated as integrated systems. The work conducted in Annex 60 has helped to share, further develop and deploy free open-source contributions of previously uncoordinated activities in modeling and simulation, based on the Modelica and Functional Mockup Interface standards.
The International Smart Grid Action Network (ISGAN) aims at fostering the global implementation of Smart Grids. Annex 7 – Smart Grid Transitions deals with the related challenges regarding institutional change and socio-technical transition of the electricity systems.
The aim was to increase the efficiency of outdoor air heat pumps in cold climates in locations with low outside temperatures of up to -25°C. Newly developed heat exchanger concepts were tested and optimized regarding their icing behaviour. Different circuit modifications were modelled and simulation studies for low ambient temperatures were carried out.
The intention of this project was to visualize the current activities of the IEA Energy Technology Network and to identify possible gaps and overlaps. The mapping includes 185 ongoing tasks and annexes (Status September 2017).
