PROJECT OVERVIEW

challenges & objectives of

the project

SERENDI-PV addresses two important challenges:

- To keep reducing the Levelized Cost of Energy (LCoE) for PV

- To make it possible to integrate a rapidly increasing share of PV power into the power networks, up to penetration levels of several dozens of percent


The objective of SERENDI-PV is to propose innovations on PV systems and their grid integration to improve:

- Lifetime, reliability, performance and profitability (including uncertainties) of PV generation;

- High-penetration of the PV generation in the grids with improved stability

Research & Development

the project's

R&D activities

SERENDI-PV project is addressing some of the main concerns which would enable the increase in the penetration of PV generated power on to the European grids. The project will address modelling, diagnostics and quality control.  

First, SERENDI-PV will provide higher accuracy of modelling for the new PV technologies (such as bifacial PV, floating PV and BIPV) allowing better energy yield assessments.

Second, the project will innovate in advanced fault diagnosis in PV plants, with special focus in fault diagnosis in the new technologies, and by using the predictive maintenance of the most complex components in PV system and with the highest impact on energy availability: PV inverter and batteries. This will be achieved by means of a better understanding of potential failures and aging processes of these components allowing to anticipate them.

Third, in addition to this, the better-quality controls in the field and in the lab will increase PV project’s quality & lifetime and reduce their performance uncertainty and improve bankability of the new PV technologies.

On the other hand, the project will address the technical challenges and opportunities that will come with the increase of the PV penetration in the grids. This will be managed, first, by means of improving PV power forecasting (mid-term, short-term and nowcasting) of the new PV technologies and in case of specific atmospheric events (snow, dust, frog). 

Second there will be the need for innovative monitoring and management of millions of distributed energy resources (PV plants) in order to maintain grid stability bringing in parallel the opportunity of additional revenues for PV (new business models). The PV data and the corresponding IT infrastructure will be utilized to develop and test several technical solutions to enable higher PV contribution and a utility friendly integration of it.

THE PROJECT's

expected innovations

A selection of the innovations of the SERENDI-PV project:

Simulation, modelling and design for better PV reliability, performance and profitability. SERENDI-PV will tackle the new challenges of modelling on four aspects: losses and degradation modelling, new PV technology/configuration modelling (such as bifacial and floating), solar resource and uncertainties modelling, and financial risk modelling.

Monitoring and image-based fault diagnosis for higher PV performance and profitability. SERENDI-PV will develop solutions and services based on five technical approaches:

a) advanced fault diagnosis in large PV plants; b) fault diagnosis in new technologies (bifacial, floating); c) data analytics algorithms for diagnostics of medium/long trend processes  d) digital twins for predictive maintenance of the most complex components, such as inverters and batteries e) improved infrared thermography data analytics.

Quality Control (QC) equipment and procedures for PV components and systems reliability

To ensure an effective quality control throughout the whole supply chain, SERENDI-PV will develop instruments (testing equipment and procedures) for:
•    Laboratory facilities, providing indoor quality controls at the component level. SERENDI-PV will address two issues: a) soiling and cleaning on the one hand; b) PV module degradation and failures in the floating environment on the other hand.
•    Field testing toolboxes, providing outdoor quality controls at the component and system level. SERENDI-PV will address another two issues: c) soiling and d) PV strings ageing/degradation.
•    Quality control procedures for e) PV inverters and f) energy storage, providing a coherent frame to exploit field and laboratory testing. 

Further innovations:

Mid-term, short-term forecasting, and nowcasting for PV system aggregations. 

Collaborative platform for modelling, data analytics, QC, databases and grid integration.

Removing technical constraints for integrating large volumes of PV in the grids

Expected Impacts

SERENDI-PV will:

Contribute to increasing the reliability of PV systems, by improving the knowledge of PV components’ and systems failure, providing better answers through operations and maintenance, developing virtual and digital twins at component level (inverters, batteries), and assessing the collective reliability of a PV fleet from a grid operators’ point of view.

Increase the real performances of PV systems by improving modelling tools for energy production forecasting and failure detection algorithms, especially for emerging applications such as the use of bifacial modules and floating PV systems.

Improve system management with high shares of PV electricity by allowing grid operators to get accurate data about the grid-connected PV fleet, energy production and service provision.

Accelerate the development of PV in Europe by improving a combination of technical and psychological factors improving its competitiveness, its ability to be seamlessly integrated into the distribution and transmission grids and to be dispatchable enough to increase its penetration in electricity grids, while providing ancillary services.

Increase the profitability of grid-connected PV systems by the reduction of some elements of the OPEX costs and influence indirectly the WACC
