[en] The impacts are getting closer, and we all know the consequences. There is probably no one in the energy industry who is not familiar with the novel "BLACKOUT-Morgen ist es zu spät" (It's Too Late in the Morning BLACKOUT), which was published on 17.6.2013.
[de]Die Einschläge kommen näher und wir kennen alle die Folgen. Es dürfte (wahrscheinlich) niemand in der Energiebranche geben, der den am 17.6.2013 erschienenen Roman "BLACKOUT-Morgen ist es zu spät" nicht kennt.
[en] Conclusions: ♦ SMR CHP has significant role in heat demand provision considering low emissions scenarios; ♦ SMR only electricity are not built; ♦ Only SMR CHP are ‘interesting’ to PLEXOS model; ♦ Due to high variability of heat demand (season but also during week) SMR CHP has rather low heat CF; ♦ SMR CHPs are superior even to Biomas CHP plants in this model.
[en] The strategic guidelines of the Armenian Long-Term State Energy Policy are Energy and Environmental Security, as well as Energy and Budget Efficiency. Nuclear Scenario Fragmentation of Energy Policy Problems: Objective - Minimization of GHG emissions in mid-century long term perspective; Criteria - Estimated Values of the appropriate positions on ecology.
[en] Key messages: 1. To achieve 2°C and 1.5°C, leading global energy scenario studies show: • Increased nuclear power deployment (and electrification); • Complementary role for nuclear and renewables. 2. Compared to current trends, more conducive market and policy conditions are needed to unlock nuclear power’s mitigation potential.
[en] Field emission arrays are attracting the attention of the scientific community due to their unique emission properties and potential technological applications. The present work deals with the Fowler–Nordheim (FN) plot behavior for virtual arrays composed of ZnO and Cu emitters with predefined geometrical properties. Electron emission is assumed to occur in these arrays based on fundamental electron tunneling with preserved emission characteristics in both semiconducting and metallic emitters (i.e., degree of field penetration near the emitter surface, band bending effects and saturation of the conduction band current at high fields). The effect of the emitter’s size distribution and the dependence of conduction band current saturation on emitter’s diameter for ZnO emitters are taken into consideration. Results show that the FN plot characteristics are greatly influenced by the investigated parameters signifying the complicated nature of field emission from these arrays. The present work is believed to be of significance for interpretation of field emission data and can assist further development of field emission arrays for future applications. (author)
[en] At a time when the world is facing global warming and the burden on natural resources is increasing. Now, the world is switching towards cleaner form of energies. Renewable solar roof top is one of them. Most developed economies of the world have started their solar programmes by targeting household rooftops. Solar power has reached grid parity and is the cheapest source of distributed power across the world
[en] The demand of energy usage is increasing rapidly and to meet the energy requirements, best possible transmission systems should be adopted to avoid energy losses in our transmission systems. In Pakistan’s WAPDA (Water & Power Development Authority) system, the rapid increase in load and less generation capacity has increased load shedding thought the country. The government has planned to increase the generation capacity but the supply companies are facing line load-ability, environmental constraints, power limitations problems etc. Most of the supply companies prefer to extend the existing electrical networks instead of building new network to reduce financial burdens. In this paper the implementation of the FACTS (Flexible AC Transmission Systems) Devices in an electrical network is described. The FACTS devices enhance power transfer capacity of the line without adding new transmission line. These devices also protect the system from overloading in case of any contingency in the electrical network. The control of power flow, reactive power compensation and voltage control are the main capabilities of FACTS devices. This paper describes the impacts of FACTS devices on improving the voltage stability and power handling capability of a transmission line. The proposed methods for the controllable flow of active and reactive power in a transmission line are also elaborated. A simple electrical system is examined to explain the improvement in the constraints of power system using FACTS devices. (author)
