COTEVOS Updates White Book “Business Opportunities and Interoperability Assessment for EV Integration”

COTEVOS Updates White Book “Business Opportunities and Interoperability Assessment for EV Integration”

The COTEVOS project (Concepts, capacities and methods for Testing EV systems and their interOperability within Smart Grids) presents an updated version of its white book “Business Opportunities and Interoperability Assessment for EV Integration” aiming to raise the awareness on the integration of Electric Vehicles.
The project ran from September 2013 until February 2016 and involved eleven partners, including DERlab, and three external parties. Led by TECNALIA, COTEVOS developed optimal structures and capacities to test the conformance, interoperability and performance of all systems making up the infrastructure for the charge of EV.

Besides the main topic of interoperability between EV and electric power system, the white book also focuses on technologies for EV integration, potential business models, and the EV system architecture. It further outlines a roadmap for interoperability assessment and interoperability test development. The white book also presents best practices as a valuable insight for industry actors into future EV development on the one hand, as well as insights into ways of enhancing ICT testing capabilities for researchers on the other. The updated version also looks deeper into exploitation aspects of EV integration.

In order to overcome the challenges in EV business development, the white book gives several recommendations to different stakeholders with regards to business models and standards development, plug-test events for standards validation, strategies to develop a pan-European interoperable testing infrastructure, and control strategies for the cost-efficient grid integration of EVs and other distributed energy resources.

Sandia’s Solar Glitter closer to Market with New Licensing Agreement

Sandia’s Solar Glitter closer to Market with New Licensing Agreement

Power Technology,Inc., founded by a Sandia National Laboratories scientist-turned-entrepreneur, has received a license for a “home-grown” technology that could revolutionise the way solar energy is collected and used. The licensing agreement was signed between mPower Technology Inc. and Sandia for microsystems enabled photovoltaics (MEPV).


mPower focuses on Dragon SCALEs, small, lightweight, flexible solar cells that fit into and power devices or sensors of any shape or size, and is led by Murat Okandan who has worked for Sandia for the last 16 years before he started his own company. MEPV uses microdesign and microfabrication techniques to make miniature solar cells, also known as “solar glitter”. mPower is commercializing MEPV as Dragon SCALEs.

The high-efficiency solar cells can be integrated into satellites and drones, biomedical and consumer electronics, and can be folded like paper for easy transport. The technology is able to leverage the massive silicon PV and microelectronics infrastructure and supply chain already in place in order to deploy solar faster and more cost effectively. The Sandia license will allow mPower to ramp up commercialisation and attract more investment. It further applies to a portion of Sandia’s MEPV intellectual property portfolio associated with silicon solar cells.

DNV GL launches Smart Cable Guard 2.0 to locate and prevent outages in a more digitalised power grid

DNV GL launches Smart Cable Guard 2.0 to locate and prevent outages in a more digitalised power grid

As the number of renewables and smart electronics added to the electricity network is constantly increasing, the power grid must cope with more dynamic stress each year. Grid operators need to be able to locate and respond to faults in the grid quickly, in order to prevent power outages and to keep the electricity network reliable and affordable.

DERlab member DNV GL has launched its upgraded Smart Cable Guard 2.0, which is a data-driven online monitoring solution. Smart Cable Guard 2.0 enables system operators to digitalize their operations and to repair weak spots before the grid fails. This will keep power grids safe and reliable, resulting up to 25% fewer failures compared to traditional methods.

NREL Researchers lend their DER Integration Expertise to IEEE Power & Energy Magazine’s March/April Issue

NREL Researchers lend their DER Integration Expertise to IEEE Power & Energy Magazine’s March/April Issue

The March/April issue of IEEE Power & Energy Magazine features new ideas and solutions on how to tackle challenges and take advantage of the opportunities of more distributed energy on the grid. The issue also presents case studies and lessons learned from those on the front lines.

NREL’s Barry Mather served as guest editor for this issue which includes two articles by NREL staff. One of them is “Achieving a 100% Renewable Grid: Operating Electric Power Systems with Extremely High Levels of Variable Renewable Energy”.

NREL publishes Landmark Residential Solar PV + Energy Storage Cost Breakdown

NREL publishes Landmark Residential Solar PV + Energy Storage Cost Breakdown

The US National Renewable Energy Laboratory (NREL) has published a landmark report extensively detailing component and system-level cost breakdowns for residential PV solar systems equipped with energy storage.


Though costs of solar systems are steadily decreasing while the economic viability of energy storage systems has increased significantly over the last several years, gaps remain in developing an in-depth understanding of the costs of combined PV and battery systems and in effectively communicating their value proposition. The report “Installed Cost Benchmarks and Deployment Barriers for Residential Solar Photovoltaics with Energy Storage: Q1 2016” serves to quantify the previously unknown or uncertain soft costs for combined solar PV and energy storage. It is the first in a series of benchmark reports that will document progress in cost reductions for the emerging PV-plus-storage market over time.

ERIGrid on Co-simulation and Integrated Laboratory Based Validation Methods

ERIGrid on Co-simulation and Integrated Laboratory Based Validation Methods

Smart grids link various types of energy technologies such as power electronics, machines, grids, and markets via communication technology, which leads to trans-disciplinary, multi-domain system. Simulation packages for assessing system integration of components typically cover only one sub-domain, while terribly simplifying the others. Co-simulation overcomes this by coupling sub-domain models that are described and solved within their native environments, using specialised solvers and validated libraries.

Covering fundamentals and applications, the articles “Applied co-simulation of intelligent power systems: implementation, usage, examples” and “Co-simulation of intelligent power systems: Fundamentals, software architecture, numerics, and coupling” discuss the state of the art and conceptually describe the main challenges for simulating intelligent power systems. Supported by ERIGrid, these papers present the work performed in the project on improving simulation-based evaluation and validation approaches.

As the focus of smart grid solutions is moving from a single system to a system of systems perspective, the increasing complexity results in growing engineering efforts and costs. For this reason, new and automated engineering methods are necessary. The paper “Engineering Smart Grids: Applying Model-Driven Development from Use Case Design to Deployment” addresses these needs with a rapid engineering methodology that covers the overall engineering process for smart grid applications—from use case design to deployment.
