As Americans continue to reel from increasing mistrust of their current leadership, René Carayol’s groundbreaking leadership book hits the U.S. shelves at a poignant time. Published by LID Publishing (http://lidpublishing.com/), "SPIKE: What Are You Great At?" redefines the traditional American idea of leadership, replacing a dated performance management approach that focuses on improving weaknesses with a philosophy that motivates people to embrace their strengths—or what René eponymously refers to as “spikes.” As an acronym, "SPIKE" represents “Strengths Positively Identified Kickstart Excellence,” but according to René, a spike is not simply something you are good at—it is something that is your brand, the essence of who you are. Although strengths-focused, "SPIKE" is not a self-help guide; rather it attempts to develop a journey for self-discovery through real and emotionally relatable anecdotes from respected global leaders (President Bill Clinton, Sir Richard Branson) and world-champion athletes (David Haye, Ricky Hatton). René stresses that none of these great leaders were ever considered flawless or well-rounded—but they all knew their two or three spikes, and took the time and energy to fine-tune them to near Olympian standards. Indeed, current American leadership is treading turbulent waters. President Donald Trump has earned an abysmal 36% approval rating—the lowest approval rating at the six-month mark of any president in 70 years, ABC News reports (https://goo.gl/v9vcCQ). If there ever was a time for leadership with the speed, agility, and ability to think the unthinkable, it is now. To achieve these seemingly impossible results, organizations must learn how to release their people from the shackles of hierarchy and control, enabling them to identify and exercise their personal spikes. René strongly advises not to become fixated upon trying to fix weaknesses in people, but to look to identify the complementary spike in another member of the team. An individual cannot be good at everything—but a team can be—if they have been selected for their standout and complementary strengths. “It took meeting René to realize that no matter what others had said to put me down or put me off my dream, as I liberated my spikes, my dream of a world title fight became my reality.” -Ashley Theophane, Professional Boxer and World Title Challenger “René is an authentic new age leader who just simply practices what he preaches and I’ve had the pleasure of benefitting from his strong support.” -Jim Yong Kim, President of the World Bank "SPIKE: What Are You Great At?" is available via Amazon: https://goo.gl/VLJzMM About René Carayol René Carayol is one of the world's leading business gurus specializing in leadership, culture, and transformation, drawing from his own unique experiences on the boards of the biggest international organizations, from Marks & Spencer and Pepsi to IPC Media and the Inland Revenue.

6 Transmission System Operators (Belgium, France, Greece, Norway, Portugal and United Kingdom) and CORESO, a TSO coordination centre, together with 13 RTD performers propose a 4 year R&D project to develop and to validate an open interoperable toolbox which will bring support, by 2015, to future operations of the pan-European electricity transmission network, thus favouring increased coordination/harmonisation of operating procedures among network operators. Under the coordination of RTE, new concepts, methods and tools are developed to define security limits of the pan European system and to quantify the distance between an operating point and its nearest security boundary: this requires building its most likely description and developing a risk based security assessment accounting for its dynamic behaviour. The chain of resulting tools meets 3 overarching functional goals: i) to provide a risk based security assessment accounting for uncertainties around the most likely state, for probabilities of contingencies and for corresponding preventive and corrective actions. ii) to construct more realistic states of any system (taking into account its dynamics) over different time frames (real-time, intraday, day ahead, etc.). iii) to assess system security using time domain simulations (with less approximation than when implementing current standard methods/tools). The prototype tool box is validated according to use cases of increasing complexity: static risk-based security approach at control zone level, dynamic security margins accounting for new power technologies (HVDC, PST, FACTS), use of data coming from off-line security screening rules into on-line security assessment, and finally security maps at pan European level. Dissemination is based on periodic workshops for a permanent user group of network operators invited to use modules to meet their own control zone needs and the ones of present or future coordination centres.

Eight Transmission System Operators (BE, CZ, FR, DE, IT, PT, CH, PL) and ENTSO-E, together with 4 associations of technology manufacturers, and 16 RTD performers propose a 3-year R&D project to develop and to apply a methodology for the long-term development of the Pan-European transmission network. The project aims at delivering a top-down methodology to support the planning from 2020 to 2050. First, it implements a set of future power scenarios, including generation units, the possible use of electricity storage and demand-side management solutions: scenarios for power localization are proposed with assumptions on the energy mix in each of the connected clusters covering the ENTSO-E area. Network studies are performed to detect the weak points when implementing the scenarios for 2050. Grid architectures options and a modular development plan are then proposed, including electricity highways, on the basis of power flow calculations, network stability analysis, socio-economic, network governance considerations, and with remarks from the consultation of European stakeholders. In parallel, an advanced planning methodology is designed, developed and tested with academic laboratories to address a few critical aspects of the above planning methodology, which may impact the robustness of the resulting architectures. This enhanced approach takes into account the correlated uncertainties in renewable generation and consumption, potential voltage and stability issues, and black-out risks including the feasibility of defence plans to avoid uncontrolled cascading failures of the candidate architectures. It includes the use of non-linear detailed models of power grids and stochastic optimization techniques. The dissemination is coordinated by ENTSO-E to reach the widest audience and to prepare the exploitation of the results. Standardization and complementary research efforts are pointed out for the future investment optimization with the support of the manufacturing industry.

Electric power systems are facing a major new challenge (and hence opportunity): future massive integration in the electric grid of electric plug-in vehicles (EV). Distribution and transmission grids and power system architectures still follow planning rules and procedures defined for the traditional operational paradigm. Therefore, it is necessary to identify and prepare solutions for the operational problems that will be caused on the electric grid, to the generation sub-system and to its commercial operation as a result of progressively increasing deployment of EV. The conceptual approach in this project involves the development of a methodology consisting of two synergetic pathways: - Development of a management and control concept that will facilitate the actual transition the MERGE concept; - Development of an evaluation suite that consists of methods and programs of modeling, analysis, and optimization of electric networks into which electric vehicles and their charging infrastructure is integrated. The MERGE concept is inspired from consideration of DER deployment but differs in that we consider now the resources to be mobile in terms of their connection to the grid. Analogies will be derived and adapted to the case of mobile resources, which can be either consumers (when in charging mode) or injectors of power (if batteries are delivering power back to the grid). By exploiting a specific computational evaluation suite that is capable of simulating real world power systems (generation, transmission and distribution) for either steady state or dynamic behavior it will be possible to test the adequacy of EV preliminary smart control interfaces that will be developed in the project. It will address comprehensively the impact of EV presence regarding steady state operation, intermittent RES integration, system stability and dynamic behavior, system restoration, regulatory aspects and market arrangements.
