Valley Area

The state and county governments in the Tennessee Valley area, particularly in Tennessee, completed 1940 with one of their most pressing financial problems solved or well on the way to solution. The threatened loss of taxes to governmental units, resulting from the program of public ownership of power and the purchase by the Tennessee Valley Authority and the municipalities of the properties of private electrical power companies, had been serious to many counties facing bankruptcy, curtailment of services, or exorbitant taxes. Besides the financial effects, the situation strikingly demonstrated the need for reforms in local government, mainly the consolidation of counties and the introduction of better budgeting and accounting practices. Moreover, the problem has also been significant because of certain issues resulting from the venture into public ownership. Should proprietary agencies of the national government engaged in competition with private business and acquiring existing taxable facilities be responsible for the taxes thereby displaced and replace them as a matter of policy? Are proprietary functions of the national government subject to state and local taxing authority? These issues have demanded widespread consideration not only in the Tennessee Valley area but also in other sections where public power programs are being tried on a large scale. A bill was introduced into Congress on September 30, 1940, to provide for payments to governmental units affected by displacement of taxes arising from the Bonneville Power Project, and a more recent bill applies to the proposed Arkansas Valley Authority Project. The passage of the Norris-Sparkman amendment by Congress in June, 1940, whereby payments in lieu of taxes are being made by the T.V.A., has answered these questions and relieved the pressing financial aspects of the situation. The tax replacement provision has now been in operation more than six months, and an analysis of the period affords an interesting insight into its effects on the various governments concerned.

Local Nature

The development of the public power program in the Tennessee Valley area has had marked effects on inter-governmental relations, in some cases creating new relationships and in other cases modifying those already existing. Many of these relations concern coöperative activities of the T. V. A. and the state and local governments, and the results of their joint endeavors have done much to expand and improve governmental services. In its relations with the local governments, the Authority has consistently followed the policy of depending on their coöperative efforts to achieve the social and economic development of the Valley without attempting to impose its will on them. “The rôles of the states, and of cities, counties, districts, and voluntary associations within the states, are enhanced, not diminished, in importance, by this recognition of interest and jurisdiction. Coöperation, not destructive competition; Federal responsibility in Federal and interstate matters, with local initiative and self-reliance in matters of a local nature—these are policies by which the development of the Valley is being and should continue to be guided.” These principles have not always been appreciated by the local units, however, and their occasional unwillingness to assume responsibilities or to fulfil obligations to each other have presented problems that have tended to hinder the most successful conduct of the public ownership program. In fact, the readjustments in inter-governmental relations that have sometimes been necessitated, especially in connection with the power program and the resulting loss of taxes, have in some instances been accompanied by painful and significant friction.

Optimal Power

The Optimal Power Flow (OPF) problem is a fundamental building block for the optimization of electrical power systems. It is nonlinear and nonconvex and computes the generator setpoints for power and voltage, given a set of load demands. It is often solved repeatedly under various conditions, either in real-time or in large-scale studies. This need is further exacerbated by the increasing stochasticity of power systems due to renewable energy sources in front and behind the meter. To address these challenges, this paper presents a deep learning approach to the OPF. The learning model exploits the information available in the similar states of the system (which is commonly available in practical applications), as well as a dual Lagrangian method to satisfy the physical and engineering constraints present in the OPF. The proposed model is evaluated on a large collection of realistic medium-sized power systems. The experimental results show that its predictions are highly accurate with average errors as low as 0.2%. Additionally, the proposed approach is shown to improve the accuracy of the widely adopted linear DC approximation by at least two orders of magnitude.

The Impact

Social considerations for a sustainable future lead to market demands for electromobility. Hence, electrical power distribution operators are concerned about the real ongoing problem of the electrification of the transport sector. In this regard, the paper aims to investigate the large-scale integration of electric vehicles in a Swedish distribution network. To this end, the integration pattern is taken into consideration as appears in the literature for other countries and applies to the Swedish culture. Moreover, different charging power levels including smart charging techniques are examined for several percentages of electric vehicles penetration. Industrial simulation tools proven for their accuracy are used for the study. The results indicate that the grid can manage about 50% electric vehicles penetration at its current capacity. This percentage decreases when higher charging power levels apply, while the transformers appear overloaded in many cases. The investigation of alternatives to increase the grid’s capabilities reveal that smart techniques are comparable to the conventional re-dimension of the grid. At present, the increased integration of electric vehicles is manageable by implementing a combination of smart gird and upgrade investments in comparison to technically expensive alternatives based on grid digitalization and algorithms that need to be further confirmed for their reliability for power sharing and energy management.

This study proposes a framework for incorporating time-dependent fragility into large-scale risk assessment models, focusing on incremental building expansion as a significant driver of changes in vulnerability. In rapidly urbanizing areas in developing countries, the pay-as-you-go process of informal building construction and staged expansion is the de facto pattern of growth. While there is a common understanding that such expansions increase the earthquake vulnerability of buildings, this study proposes a framework to model and quantify this increase. Vulnerability curves are developed through incremental dynamic structural analysis for common building expansion typologies. Building expansions are modeled as Markov chain processes and used to simulate stochastic expansion sequences over a building's lifetime. The model is then used to simulate a hypothetical neighborhood in the Kathmandu valley area to understand neighborhood-level risk over time. The study provides a new methodology to analyze changing seismic risk over time, driven by any building modification that impacts the building's vulnerability (incremental expansion, deterioration, retrofit, etc.).

AbstractWhen a large chemical incident occurs and people are injured, public health agencies need to be able to provide guidance and respond to questions from the public, the media, and public officials. Because of this urgent need for information to support appropriate public health action, the Agency for Toxic Substances and Disease Registry (ATSDR) of the US Department of Health and Human Services has developed the Assessment of Chemical Exposures (ACE) Toolkit. The ACE Toolkit, available on the ATSDR website, offers materials including surveys, consent forms, databases, and training materials that state and local health personnel can use to rapidly conduct an epidemiologic investigation after a large-scale acute chemical release. All materials are readily adaptable to the many different chemical incident scenarios that may occur and the data needs of the responding agency. An expert ACE team is available to provide technical assistance on site or remotely. (Disaster Med Public Health Preparedness. 2016;10:631–632)

From the first self-sustaining nuclear reaction to the present day represents a span of three decades: within that time large-scale generation of electrical power from nuclear energy has become acknowledged as economic, safe and environmentally acceptable. Within the U .K . 10% of electricity consumed is of nuclear origin. Some of the C.E.G.B. reactors have been in service for over 10 years. The operating experience that has been gained shows how the original design concepts have been ultimately developed. Some of the difficulties encountered and the engineering solutions are presented. Operating experience feeds back to the design philosophy and safety requirements for future nuclear plant. In this way a foundation is provided for the further exploitation of what must become a major source of energy in the next decade.

Arvien aktuālāki kļūst jautājumi par valsts un pašvaldības institūciju kompetenci sabiedriskās kārtības un drošības garantēšanā publisku pasākumu laikā. Tiesību aizsardzības iestādēm viens no svarīgākajiem uzdevumiem ir sabiedriskās kārtības un drošības garantēšana šo pasākumu norises vietās. Lai arī būtiska loma tās nodrošināšanā ir atvēlēta pašvaldību institūcijām (pašvaldības policija šobrīd ir viens no nozīmīgākajiem Valsts policijas sadarbības partneriem policijas funkciju pildīšanā), praksē novērojamas vairākas problēmas. Pirmkārt, vai valsts un pašvaldības policijas iestādēm ir pietiekami materiāltehniskie un cilvēkresursi, lai garantētu sabiedrisko kārtību liela mēroga (arī paaugstināta riska) publiskos pasākumos? Otrkārt, vai šo iestāžu darbinieki publisku pasākumu laikā izmanto samērīgus tiesiskos līdzekļus, lai vērstos pret sabiedriskās kārtības pārkāpējiem? Issues affecting the state and local government institution competence in public order and security maintaining in public events is becoming increasingly crucial. One of the most important tasks of the law enforcement agencies is guaranteeing public order and security. Although the crucial role in guaranteeing is devoted to local government bodies, where municipal police institute is currently one of the most important partners of the State Police in police powers provision, in practice are turning out a number of problems. First, whether the state and municipal police authorities have sufficient logistical and human resources to ensure public order in large-scale (and sensitive) public events. Second, whether the enforcement officers during public events use proportionate legal means to crack down violators of public order.

The Impact

<p><em>Environmental concerns along with the increasing demand on electrical power, have led to power generation of renewable sources like wind. Connecting wind turbines in large scale powers with transmission network makes new challenges like the impact of these renewable sources on power system protection. This paper studies the impact of fault resistance and its location on voltage and current fundamental frequencies of faulted lines connected to DFIG based wind farms and it will be demonstrated that because of the large differences between these frequencies, impedance measuring of distance relays is inefficient. Hence in these power systems using conventional impedance measurements is not suitable anymore and new impedance measuring approaches are required in distance relays.</em></p>
