‘Repowering Europe’ conference – Day 1 – greater penetrations of
PV through optimal use of the grid
Brussels, 19th May 2016
The joint annual meeting of the European Technology and Innovation Platform (ETIP) on
Photovoltaics and the ETIP on Smartgrids was hailed by Jeroen Schuppers, deputy Head
of Unit for Advanced Energy Production in DG Research and Innovation of the European
Commission as “very timely and relevant […] The event brings together two groups.
Col aboration and cooperation is the main objective of the Energy Union.”
110 attended day 1 of the conference, which was held under the banner
‘Photovoltaics: centre-stage in the power system'.
Fairness in al ocating the costs for ensuring system adequacy was a sensitive discussion
point. There has been a steep rise in the number of PV systems serving particular
buildings. These buildings may stil need to take electricity from the grid from time to time
(night, cloudy days etc). How should this service be remunerated, now that the
building’s overal demand for grid electricity is less?
Dr Venizelos Efthymiou, co-organiser of the conference, said, “Capacity payments [fees
that change little or not at all with respect to overal electricity consumption] are a way
of reflecting the cost implications of utilising the integrated grid.” But Solar Power Europe
CEO Dr James Watson said, “There should be no move at this point in having grid tariffs
put on self-consumed solar electricity […] Let’s not create any more barriers for this
energy transition especial y when we’re doing so wel and becoming daily more and
more competitive.” He said Solar Power Europe “could support the energy-only market,
reformed to have 15-minute gate-closure times and increased intra-day trading” as the
primary way of ensuring system adequacy. Furthermore, according to Watson,
payments that help to keep existing technologies in the market should be removed (“we
need a very orderly ‘retreat-from-coal’ plan”), while incentives and / or tariff
restructuring to harness demand-response and storage should be created.
As to the relative positioning of demand response and electricity storage, Marion Perrin
(head of storage and electrical systems at CEA-INES) said, “Storage is the last flexibility
option. There are plenty other solutions to integrate PV before needing to use a battery.”
Advances in forecasting tools and system intel igence, including in features that may be
incorporated into inverters, were highlighted as developments that wil make PV systems
responsive to system needs.
Dr Pierre-Jean Alet, leader of ETIP PV’s Grid Integration working group, was struck by the
correlation between greater penetrations of PV and wind, and decreasing grid outages
in Germany and Italy: “Distributed renewable generation is triggering a rethink of how the
grid operates, leading to better service quality for al .”
Several research projects (or initiatives) (all of them EU-funded) were picked out by
presenters as having made a useful contribution to the chal enge of integrating PV into
the grid: EEBUS, the Horizon 2020 projects Migrate and Flexiciency and the FP7 project
Sustainable.
