New technologies or approaches are being widely developed and proposed to be deployed in real energy systems to improve desired objectives; however, supporting decision making processes to select best solutions in terms of performance and efficiently following cost-benefit analysis require some sort of scientific evidence based tools. These tools should be reliable, robust, and capable of demonstrating the behaviour and impact of newly developed devices or algorithms in different pre- defined scenarios. Therefore, new approaches and technologies need to be tested and verified using a safe laboratory test environment.This report is about the development and realisation of some major tools and reliable methods to calculate risks and opportunities for integrating of new energy resources into the European electricity grid. Hanze University Groningen and Politecnico di Torino worked together within the STORE&GO project sharing laboratories, knowledge, hardware facilities and researchers for the realisation of the characterisation and mathematical modelling of renewable resources. Needed to realize a stable and reliable environment for remote physical hardware in the loop simulations.For this realisation we started with the local characterisation of a PV-Field and a PEM electrolyser at Entrance Groningen by logging and measuring the electric behaviour and specific device parameters to integrate and convert these into working mathematical models of a PV-Field and electrolyser prosumer. After testing and evaluating these models by comparing the results with the real-time measurements, these test and modelling is also realised from the remote laboratory in Torino. To achieve dynamical physical hardware we also realised dynamic mathematical model(s) with real-time functionality to interact directly with the remote electrolyser. To connect both the laboratories with full duplex communication functionalities between physical hardware and models we have also realized a network which is able to share network resources on both local and remote sites.

tract Micro wind turbines can be structurally integrated on top of the solid base of noise barriers near highways. A number of performance factors were assessed with holistic experiments in wind tunnel and in the field. The wind turbines underperformed when exposed in yawed flow conditions. The theoretical cosθ theories for yaw misalignment did not always predict power correctly. Inverter losses turned out to be crucial especially in standby mode. Combination of standby losses with yawed flow losses and low wind speed regime may even result in a net power consuming turbine. The micro wind turbine control system for maintaining optimal power production underperformed in the field when comparing tip speed ratios and performance coefficients with the values recorded in the wind tunnel. The turbine was idling between 20%–30% of time as it was assessed for sites with annual average wind speeds of three to five meters per second without any power production. Finally, the field test analysis showed that inadequate yaw response could potentially lead to 18% of the losses, the inverter related losses to 8%, and control related losses to 33%. The totalized loss led to a 48% efficiency drop when compared with the ideal power production measured before the inverter. Micro wind turbine’s performance has room for optimization for application in turbulent wind conditions on top of noise barriers. https://doi.org/10.3390/en14051288

In maart 2011 dreigde Muammer Gaddafi van Libya duizenden onschuldige burgers van de stad Benghazi uit hun huizen te halen om hen te vermoorden. De Veiligheidsraad van de Verenigde Naties verwees de situatie door naar het Internationaal Strafhof in Den Haag, dwong een no-flyzone af en gaf de NAVO een mandaat om burgers te beschermen with all necessary means, met de uitzondering van grondtroepen. Deze operatie was snel, robuust en effectief. Het principe van The Responsibility to Protect (R2P) -de verantwoordelijkheid van de internationale gemeenschap om genocide, misdaden tegen de menselijkheid, etnische zuivering en oorlogsmisdaden te voorkomen en te stoppen- werd voor het eerst volledig toegepast. Is R2P daarmee een norm geworden? Dit onderzoek plaatst de casus Libië in het model van de "Norm Life Cycle" (de levenscyclus van een norm) van de Constructivistische theoretici Finnemore en Sikkink (1998). Libië toont aan dat R2P nu een tipping point (omslagpunt) heeft bereikt, en zich van de fase norm emergence (opkomende norm) naar de fase norm cascade heeft verplaatst. Er is echter een spanning ontstaan: de terughoudendheid van de Veiligheidsraad om R2P toe te passen in Syrië (2012) wijst de andere kant uit. Er is dus nog een lange weg te gaan, voordat R2P als een internalised norm (vanzelfsprekende norm) kan worden beschouwd. ABSTRACT In March 2011, Muammar Gaddafi of Libya threatened to pull thousands of civilian protesters in the city of Benghazi out of their homes and kill them. The Security Council of the United Nations referred the crisis to the International Criminal Court, imposed a no-fly zone and provided NATO with a mandate to protect civilians by all necessary means, with the exception of ground troops. This operation was fast, robust and effective. It also marked the first time that the Responsibility to Protect (R2P) principle was fully implemented, being the responsibility of the international community to prevent and respond to genocide, crimes against humanity and war crimes if the state in question is not able or not willing to protect its citizens itself. Has R2P become a new norm? This study situates the case of Libya in the 'Norm Life Cycle' model of Constructivist theorists Finnemore and Sikkink (1998). It suggests that R2P has reached a tipping point and has moved from the stage of norm emergence to the stage of norm cascade. However, a certain tension still exists: the reluctance of the Security Council to implement R2P again in the crisis in Syria (2012)points in the opposite direction. This suggests there is still a long way to go before R2P becomes an internalised norm in the international community.
