This Expert Group Report provides recommendations on how to perform studies of wind and solar PV integration. It is based on more than 10 years of work within the International Energy Agency Wind Technology Collaboration Programme (IEA Wind TCP) Task 25: Design and Operation of Power Systems with Large Amounts of Wind Power and the IEA Photovoltaic Power System Programme (PVPS) TCP Task 14: High Penetration of PV Systems in Electricity Grids.
The report is issued as an IEA Wind TCP Recommended Practices (RP) document to provide research institutes, consultants, and system operators with the best available information on how to perform an integration study. An integration study seeks to find issues to energy systems, as well as mitigation measures, to absorb certain amounts of generation from wind or solar energy. This is the first update of the recommendations, adding solar photovoltaics (PV) to the previous edition on Recommended Practices for Wind Integration Studies. The update also benefits from comprehensive review of recent integration studies based on real integration experiences and improved integration study methodologies for both wind and photovoltaics.
This Expert Group Report describes the methodologies, study assumptions, and inputs needed to conduct a wind and PV integration study. Findings and results from previous wind integration studies are discussed in the summary reports and solar integration studies.
In RP 16, the Task 25 Expert Group developed a flow chart that outlines the phases of a complete wind integration study. In this second edition, the flow chart has been updated through close collaboration between Task 25 and Task 14 experts and is also applied to integration studies for photovoltaics. The flow chart describes a comprehensive yet flexible process which can be adapted to the specific objectives and requirements of the individual study. It covers aspects ranging from transmission system integration down to the distribution level, which is of particular relevance for solar PV.
Conducting a full study is a complicated process, especially taking into account all possible iteration loops. It may not be feasible or necessary for all integration studies to perform each phase included in the flow chart. The flow chart shows these relationships and points out the importance of the study set-up assumptions to results. It also allows reviewers to understand what was completed in any particular study and what was not, providing a context for comparison.
Rapid global urbanization and the increase of the Urban Heat Island (UHI) effect make urban cooling a necessity as well as an opportunity to increase the liveability and amenity of cities. This review is a scoping study of the relevant worldwide UHI mitigation/adaptation...Read more
Financing the upfront costs of energy efficiency and renewable energy projects in buildings can be a significant barrier to the expansion of sustainable, low carbon buildings, despite this being a low-cost option on the carbon abatement curve. Systematic literature on...Read more
Australia's Chief Scientist Alan Finkel points out, in this interview, the need for Australia to develop better storage systems and reflects on the recent report from ACOLA. California Energy Commissioner Andrew McAllister, also warns Australia to pursue demand side...Read more
In this report the effects of PV integration into diesel driven micro-grids was investigated. The focus was set to the fuel saving potential due to the PV integration and the resulting economics for the system.
The report starts with a summary of the most relevant technical aspects that need to be considered for the integration of PV in a diesel driven micro-grid.
This report summarises the findings from Stage 1 of the Future Grid Homes project, which involved in-depth and at-home interviews with 51 Australian households in five National Energy Market (NEM) states and territories (VIC, SA, NSW, ACT and QLD).
America has entered the “coal cost crossover” where existing coal is more expensive than cleaner alternatives. This report shows that today, local wind and solar could replace 74 percent of the U.S. coal fleet at an immediate savings to customers. By 2025, this number grows to 86 percent of the coal fleet.
The energy sector is undergoing a paradigm shift. By 2050, many predictions identify a future electric grid system in which renewables make up a significant share (30% or more) of overall electricity generation. In the fall of 2017, wind energy experts from around the world came together to look at an even grander vision of the future electricity system where wind energy could produce a majority (>50%) of global electricity generation.
