iDistributedPV newsletter

iDistributedPV aims at developing affordable integrated solutions to enhance the penetration of distributed solar PV (e.g. households/larger buildings/park areas) based on the effective integration of solar PV equipment, energy storage, monitoring and controlling strategies and procedures, active demand management, smart technologies and the integration of procedures in the power distribution system according to market criteria.

A “solution” in the context of the iDistributedPV project refers to a combination of a PV system and a load which is connected to the distribution grid, optionally supplemented by a battery system and/or demand side management technology. Eight solutions were identified for applications in Europe, distinguished by the arrangement of investor, operator and consumer: homeowner (single-family house), company as investor, contractors, municipal buildings (state as investor), controllable load, multi-family house (investor sells electricity to tenants), community storage (shared storage) and virtual power plant. Moreover, for each of the countries, the partners described the status and the political framework and provided data on electricity prices.

In the first year of the project, the partners have also analysed the existing barriers in 14 EU countries, in technical, regulatory and economic terms and identified a set of Key Performance Indicators (KPIs) in order to evaluate afterwards the solutions from a technical, economic and environmental point of view. Moreover, a simulation tool was developed in order to properly size the components of the solution based on the production profile and its volatility, the demand pattern and its volatility and the technical characteristics of the energy storage devices.

 iDistributedPV latest coordination meeting took place in Warsaw, Poland, on 16-17 October, in order to analyse the progress of the project and the forthcoming activities. Partners discussed about the case studies that were selected for the simulations and presented some preliminary results of the homeowner case study. Poland and Greece have a net-metering scheme for their PV installations, Lithuania’s main players under consideration will be a private user with a PV installation up to 10 kW, and an industrial user with a solar power installation up to 100 kW, Spain’s first study in three locations with 3 different level of irradiation in Spain showed that there is not economic benefit with the batteries investment, but other KPIs improved and in Germany, a study has been done not only with a storage system inside the solution, but also for fuel cells, heat pumps and electric vehicles, for 3 scenarios with need of grid reinforcement (0% battery systems, 50% battery systems, 100% battery system). Moreover, Fraunhofer ISE and Deloitte also presented an analysis of the impact of distributed solar PV on the German/Spanish wholesale electricity market price. Indicatively, in Spain, the impact of 1 TWh of distributed solar PV generation on the Wholesale electricity market price was studied for the years 2016, 2017. Deloitte reached to the conclusion that the profile of the consumption has low impact in the price of the pool and the shape of the slope in the Iberian market leads to a mitigation in the impact of DER. Fraunhofer ISE study was based on the impact of distributed solar PV on the electricity price through the merit-order effect and the results of the scatterplot over residual load showed that there is a mismatch mainly in the extreme price and residual load area. However, they matched most of the time.

In the following months, iDistributedPV members from each country will choose the most appropriate solutions within their borders to be analysed and evaluated from technical, economical and regulatory perspective. iDistributedPV will quantify the contribution of the solutions in terms of frequency and voltage control, the capacity to supply/demand electricity to/from the system, the maximum level of solar PV penetration and the contribution of the solution to provide ancillary services. It will also quantify the cost-benefits and the rate of return of the solutions, and the comparative analysis of the levelized cost of electricity (LCOE) of distributed solar PV solutions with the LCOE of the existing supply alternatives. Based on the evaluation of the KPIs, iDistributedPV will also identify the most promising solutions and make a gap analysis between them and the current situation.

Next coordination meeting will take place in Athens, in March/April 2019.
